8e611b42aa Fix bug in add_conditional_edges when no path_map is provided (#809)
* Fix bug in add_conditional_edges when no path_map is provided

When an instance of a callable class is passed as the path arg to
add_conditional_edges but no path_map is provided, get_type_hints(path) is
called, which raises a TypeError (since get_type_hints only accepts a module,
class, method, or function).

This patch fixes the error by trying to get type hints from path.__call__ first,
which should work for instances of callable classes.

Tested: Added a test that raises TypeError without the fix in this patch but
passes with the fix.

* More defensive, additional test

# Contributing to LangGraph
Thank you for being interested in contributing to LangGraph!
## General guidelines
Here are some things to keep in mind for all types of contributions:
- Follow the ["fork and pull request"](https://docs.github.com/en/get-started/exploring-projects-on-github/contributing-to-a-project) workflow.
- Fill out the checked-in pull request template when opening pull requests. Note related issues and tag relevant maintainers.
- Ensure your PR passes formatting, linting, and testing checks before requesting a review.
- If you would like comments or feedback, please open an issue or discussion and tag a maintainer.
- Backwards compatibility is key. Your changes must not be breaking, except in case of critical bug and security fixes.
- Look for duplicate PRs or issues that have already been opened before opening a new one.
- Keep scope as isolated as possible. As a general rule, your changes should not affect more than one package at a time.
### Bugfixes
For bug fixes, please open up an issue before proposing a fix to ensure the proposal properly addresses the underlying problem. In general, bug fixes should all have an accompanying unit test that fails before the fix.
### New features
For new features, please start a new [discussion](https://github.com/langchain-ai/langgraph/discussions), where the maintainers will help with scoping out the necessary changes.
## Contribute Documentation
Documentation is a vital part of LangGraph. We welcome both new documentation for new features and
community improvements to our current documentation. Please read the resources below before getting started:

## Documentation Style Guide
As LangGraph continues to grow, the surface area of documentation required to cover it continues to grow too.
This page provides guidelines for anyone writing documentation for LangGraph, as well as some of our philosophies around organization and structure.
## Philosophy
LangGraph's documentation follows the [Diataxis framework](https://diataxis.fr).
Under this framework, all documentation falls under one of four categories: [Tutorials](#tutorials),
[How-to guides](#how-to-guides),
[References](#references), and [Explanations (aka conceptual guides)](#conceptual-guide).
### Tutorials
Tutorials are lessons that take the reader through a practical activity. Their purpose is to help the user
gain understanding of concepts and how they interact by showing one way to achieve some goal in a hands-on way.
They should **avoid** giving
multiple permutations of ways to achieve that goal in-depth. Choice is burdensome. Instead, they should guide a new user through a recommended path to accomplishing a concrete goal. While the end result of a tutorial does not necessarily need to
be completely production-ready, it should be useful and practically satisfy the the goal that you clearly stated in the tutorial's introduction.
To quote the Diataxis website:
> A tutorial serves the users *acquisition* of skills and knowledge - their study. Its purpose is not to help the user get something done, but to help them learn.
In LangGraph, these are often higher level guides that show off end-to-end use cases.
Some examples include:
- [Build a Customer Support Bot](https://langchain-ai.github.io/langgraph/tutorials/customer-support/customer-support/)
- [Build a SQL Agent](https://langchain-ai.github.io/langgraph/tutorials/sql-agent/)
Here are some high-level tips on writing a good tutorial:
- Focus on guiding the user to get something done, but keep in mind the end-goal is more to impart principles than to create a perfect production system.
- Be specific, not abstract and follow one path.
- No need to go deeply into alternative approaches, but its ok to reference them, ideally with a link to an appropriate how-to guide.
- Get "a point on the board" as soon as possible - something the user can run that outputs something.
- You can iterate and expand afterwards.
- Try to frequently checkpoint at given steps where the user can run code and see progress.
- Focus on results, not technical explanation.
- Crosslink heavily to appropriate conceptual/reference pages
- The first time you mention a LangGraph concept, use its full name (e.g. "human-in-the-loop"), and link to its conceptual/other documentation page.
- It's also helpful to add a prerequisite callout that links to any pages with necessary background information.
- End with a recap/next steps section summarizing what the tutorial covered and future reading, such as related how-to guides.
- Use phrases like "Next we can run X & Y. We will expect Z.". Then afterwards, use language like "Notice Z" that recalls our expectations and directs the reader's attention to the topic we are trying to teach.
- Do not shy away from repetition.
### How-to guides
A how-to guide, as the name implies, demonstrates how to do something discrete and specific.
It should assume that the user is already familiar with underlying concepts, and is trying to solve an immediate problem, but
should still give some background or list the scenarios where the information contained within can be relevant.
They can and should discuss alternatives if one approach may be better than another in certain cases.
To quote the Diataxis website:
> A how-to guide serves the work of the already-competent user, whom you can assume to know what they want to do, and to be able to follow your instructions correctly.
Some examples include:
- [How to add persistence to your graph](https://langchain-ai.github.io/langgraph/how-tos/persistence/)
- [How to view and update past graph state](https://langchain-ai.github.io/langgraph/how-tos/human_in_the_loop/time-travel/)
Here are some high-level tips on writing a good how-to guide:
- Clearly explain what you are guiding the user through at the start
- Assume higher intent than a tutorial and show what the user needs to do to get that task done
- Assume familiarity of concepts, but explain why suggested actions are helpful
- Crosslink heavily to conceptual/reference pages
- Discuss alternatives and responses to real-world tradeoffs that may arise when solving a problem
- Use lots of example code, ideally within complete code blocks that the reader can copy and run.
- End with a recap/next steps section summarizing what the tutorial covered and future reading, such as other related how-to guides
### Conceptual guides
LangGraph's conceptual guides fall under the **Explanation** quadrant of Diataxis. They should cover LangChain terms and concepts
in a more abstract way than how-to guides or tutorials, and should be geared towards curious users interested in
gaining a deeper understanding of the framework. Try to avoid excessively large code examples. The goal here is to
impart perspective to the user rather than to finish a practical project. These guides should cover **why** things work they way they do.
To quote the Diataxis website:
> The perspective of explanation is higher and wider than that of the other types. It does not take the users eye-level view, as in a how-to guide, or a close-up view of the machinery, like reference material. Its scope in each case is a topic - “an area of knowledge”, that somehow has to be bounded in a reasonable, meaningful way.
Some examples include:
- [What does it mean to be agentic?](https://langchain-ai.github.io/langgraph/concepts/high_level/)
- [Tool calling](https://langchain-ai.github.io/langgraph/concepts/agentic_concepts/#tool-calling)
Here are some high-level tips on writing a good conceptual guide:
- Explain design decisions. Why does concept X exist and why was it designed this way?
- Use analogies and reference other concepts and alternatives
- Avoid blending in too much reference content
- You can and should reference content covered in other guides, but make sure to link to them
### References
References contain detailed, low-level information that describes exactly what functionality exists and how to use it.
In LangGraph, this is mainly our API reference pages, which are populated from docstrings within code.
References pages are generally not read end-to-end, but are consulted as necessary when a user needs to know
how to use something specific.
To quote the Diataxis website:
> The only purpose of a reference guide is to describe, as succinctly as possible, and in an orderly way. Whereas the content of tutorials and how-to guides are led by needs of the user, reference material is led by the product it describes.
Many of the reference pages in LangChain are automatically generated from code,
but here are some high-level tips on writing a good docstring:
- Be concise
- Discuss special cases and deviations from a user's expectations
- Go into detail on required inputs and outputs
- Light details on when one might use the feature are fine, but in-depth details belong in other sections.
Each category serves a distinct purpose and requires a specific approach to writing and structuring the content.
## General guidelines
Here are some other guidelines you should think about when writing and organizing documentation.
We generally do not merge new tutorials from outside contributors without an actue need.
We welcome updates as well as new integration docs, how-tos, and references.
### Avoid duplication
Multiple pages that cover the same material in depth are difficult to maintain and cause confusion. There should
be only one (very rarely two), canonical pages for a given concept or feature. Instead, you should link to other guides.
### Link to other sections
Because sections of the docs do not exist in a vacuum, it is important to link to other sections as often as possible
to allow a developer to learn more about an unfamiliar topic inline.
This includes linking to the API references as well as conceptual sections!
### Be concise
In general, take a less-is-more approach. If a section with a good explanation of a concept already exists, you should link to it rather than
re-explain it, unless the concept you are documenting presents some new wrinkle.
Be concise, including in code samples.
### General style
- Use active voice and present tense whenever possible
- Use examples and code snippets to illustrate concepts and usage
- Use appropriate header levels (`#`, `##`, `###`, etc.) to organize the content hierarchically
- Use fewer cells with more code to make copy/paste easier
- Use bullet points and numbered lists to break down information into easily digestible chunks
- Use tables (especially for **Reference** sections) and diagrams often to present information visually
- Include the table of contents for longer documentation pages to help readers navigate the content, but hide it for shorter pages
## Setup
LangChain documentation consists of two components:
1. Main Documentation: Hosted at [https://langchain-ai.github.io](https://langchain-ai.github.io/langgraph/),
this comprehensive resource serves as the primary user-facing documentation.
It covers a wide array of topics, including tutorials, use cases, integrations,
and more, offering extensive guidance on building with LangGraph.
The content for this documentation lives in the `/docs` directory of the monorepo.
2. In-code Documentation: This is documentation of the codebase itself, which is also
used to generate the externally facing [API Reference](https://langchain-ai.github.io/langgraph/reference/graphs/).
The content for the API reference is autogenerated by scanning the docstrings in the codebase. For this reason we ask that developers document their code well.
We appreciate all contributions to the documentation, whether it be fixing a typo,
adding a new tutorial or example and whether it be in the main documentation or the API Reference.
### 📜 Main Documentation
The content for the main documentation is located in the `/docs` directory of the monorepo.
The documentation is written using a combination of ipython notebooks (`.ipynb` files)
and markdown (`.md` files). The notebooks are converted to markdown
and then built using [MkDocs](https://www.mkdocs.org/).
Feel free to make contributions to the main documentation! 🥰
After modifying the documentation:
1. Run the linting and formatting commands (see below) to ensure that the documentation is well-formatted and free of errors.
2. Optionally build the documentation locally to verify that the changes look good.
3. Make a pull request with the changes.
### ⚒️ Linting and Building Documentation Locally
After writing up the documentation, you may want to lint and build the documentation
locally to ensure that it looks good and is free of errors.
If you're unable to build it locally that's okay as well, as you will be able to
see a preview of the documentation on the pull request page.
From the **monorepo root**, run the following command to install the dependencies:
```bash
poetry install --with docs --no-root
```
#### Building
The code that builds the documentation is located in the `/docs` directory of the monorepo.
Before building the documentation, it is always a good idea to clean the build directory:
```bash
make clean-docs
```
You can build and preview the documentation as outlined below:
```bash
make serve-docs
```
#### Linting
The documentation is linted from the **monorepo root**. To lint it, run the following from there:
```bash
make spellcheck
```
### In-code Documentation
The in-code documentation is autogenerated from docstrings.
For the API reference to be useful, the codebase must be well-documented. This means that all functions, classes, and methods should have a docstring that explains what they do, what the arguments are, and what the return value is. This is a good practice in general, but it is especially important for LangChain because the API reference is the primary resource for developers to understand how to use the codebase.
We generally follow the [Google Python Style Guide](https://google.github.io/styleguide/pyguide.html#38-comments-and-docstrings) for docstrings.
Here is an example of a well-documented function:
```python
def my_function(arg1: int, arg2: str) -> float:
"""This is a short description of the function. (It should be a single sentence.)
This is a longer description of the function. It should explain what
the function does, what the arguments are, and what the return value is.
It should wrap at 88 characters.
Examples:
This is a section for examples of how to use the function.
.. code-block:: python
my_function(1, "hello")
Args:
arg1: This is a description of arg1. We do not need to specify the type since
it is already specified in the function signature.
arg2: This is a description of arg2.
Returns:
This is a description of the return value.
"""
return 3.14
```

## Overview
[LangGraph](https://langchain-ai.github.io/langgraph/) is a library for building stateful, multi-actor applications with LLMs, used to create agent and multi-agent workflows. Compared to other LLM frameworks, it offers these core benefits: cycles, controllability, and persistence. LangGraph allows you to define flows that involve cycles, essential for most agentic architectures, differentiating it from DAG-based solutions. As a very low-level framework, it provides fine-grained control over both the flow and state of your application, crucial for creating reliable agents. Additionally, LangGraph includes built-in persistence, enabling advanced human-in-the-loop and memory features.

One of the central concepts of LangGraph is state. Each graph execution creates a state that is passed between nodes in the graph as they execute, and each node updates this internal state with its return value after it executes. The way that the graph updates its internal state is defined by either the type of graph chosen or a custom function.
Let's take a look at a simple example of an agent that can search the web using [Tavily Search API](https://tavily.com/).

# API Concepts
This page describes the high-level concepts of the LangGraph Cloud API. The conceptual guide of LangGraph (Python library) is [here](../../concepts/index.md).
## Data Models
The LangGraph Cloud API consists of a few core data models: [Assistants](#assistants), [Threads](#threads), [Runs](#runs), and [Cron Jobs](#cron-jobs).
### Assistants
An assistant is a configured instance of a [`CompiledGraph`](../../../reference/graphs/#compiledgraph). It abstracts the cognitive architecture of the graph and contains instance specific configuration and metadata. Multiple assistants can reference the same graph but can contain different configuration and metadata, which may differentiate the behavior of the assistants. An assistant (i.e. the graph) is invoked as part of a run.
An assistant is a configured instance of a [`CompiledGraph`][compiledgraph]. It abstracts the cognitive architecture of the graph and contains instance specific configuration and metadata. Multiple assistants can reference the same graph but can contain different configuration and metadata, which may differentiate the behavior of the assistants. An assistant (i.e. the graph) is invoked as part of a run.
The LangGraph Cloud API provides several endpoints for creating and managing assistants. See the <a href="../reference/api/api_ref.html#tag/assistantscreate" target="_blank">API reference</a> for more details.
### Threads
A thread contains the accumulated state of a group of runs. If a run is executed on a thread, then the [state](../../../concepts/#persistence) of the underlying graph of the assistant will be persisted to the thread. A thread's current and historical state can be retrieved. To persist state, a thread must be created prior to executing a run.
A thread contains the accumulated state of a group of runs. If a run is executed on a thread, then the [state][state] of the underlying graph of the assistant will be persisted to the thread. A thread's current and historical state can be retrieved. To persist state, a thread must be created prior to executing a run.
The state of a thread at a particular point in time is called a checkpoint.
For more on threads and checkpoints, see this section of the [LangGraph conceptual guide](../../concepts/low_level.md#checkpointer).
The LangGraph Cloud API provides several endpoints for creating and managing threads and thread state. See the <a href="../reference/api/api_ref.html#tag/threadscreate" target="_blank">API reference</a> for more details.
### Runs
A run is an invocation of an assistant. Each run may have its own input, configuration, and metadata, which may affect execution and output of the underlying graph. A run can optionally be executed on a thread.

Streaming is critical for making LLM applications feel responsive to end users. When creating a streaming run, the streaming mode determines what data is streamed back to the API client. The LangGraph Cloud API supports five streaming modes.
- `values`: Stream the full state of the graph after each node is executed. See the [How-to Guide](../how-tos/cloud_examples/stream_values/) for streaming values.
- `messages`: Stream complete messages (at the end of node execution) as well as tokens for any messages generated inside a node. This mode is primarily meant for powering chat applications. This is only an option if your graph contains a `messages` key. See the [How-to Guide](../how-tos/cloud_examples/stream_messages/) for streaming messages.
- `updates`: Streams updates to the state of the graph after each node is executed. See the [How-to Guide](../how-tos/cloud_examples/stream_updates/) for streaming updates.
- `events`: Stream all events (including the state of the graph) after each node is executed. See the [How-to Guide](../how-tos/cloud_examples/stream_events/) for streaming events. This can be used to do token-by-token streaming for LLMs.
- `debug`: Stream debug events after each node is executed. See the [How-to Guide](../how-tos/cloud_examples/stream_debug/) for streaming debug events.
Streaming is critical for making LLM applications feel responsive to end users. When creating a streaming run, the streaming mode determines what data is streamed back to the API client. The LangGraph Cloud API supports five streaming modes.
You can also specify multiple streaming modes at the same time. See the [How-to Guide](../how-tos/cloud_examples/stream_multiple/) for configuring multiple streaming modes at the same time.
- `values`: Stream the full state of the graph after each node is executed. See the [how-to guide](../how-tos/stream_values.md) for streaming values.

### Human-in-the-Loop
There are many occasions where the graph cannot run completely autonomously. For instance, the user might need to input some additional arguments to a function call, or select the next edge for the graph to continue on. In these instances, we need to insert some human in the loop interaction, which you can learn about in the [human in the loop how-tos](../how-tos/cloud_examples/human_in_the_loop_breakpoint).

### Double Texting
Many times users might interact with your graph in unintended ways. For instance, a user may send one message and before the graph has finished running send a second message. To solve this issue of "double-texting" (i.e. prompting the graph a second time before the first run has finished), Langgraph has provided four different solutions, all of which are covered in the [Double Texting how-tos](../how-tos/cloud_examples/interrupt_concurrent/). These options are:
- `reject`: This is the simplest option, this just rejects any follow up runs and does not allow double texting. See the [How-to Guide](../how-tos/cloud_examples/reject_concurrent/) for configuring the reject double text option.
- `enqueue`: This is a relatively simple option which continues the first run until it completes the whole run, then sends the new input as a separate run. See the [How-to Guide](../how-tos/cloud_examples/enqueue_concurrent/) for configuring the enqueue double text option.
- `interrupt`: This option interrupts the current execution but saves all the work done up until that point. It then inserts the user input and continues from there. If you enable this option, your graph should be able to handle weird edge cases that may arise. See the [How-to Guide](../how-tos/cloud_examples/interrupt_concurrent/) for configuring the interrupt double text option.
- `rollback`: This option rolls back all work done up until that point. It then sends the user input in, basically as if it just followed the original run input. See the [How-to Guide](../how-tos/cloud_examples/rollback_concurrent/) for configuring the rollback double text option.

Stateless runs are still retried as regular retries are per node, while everything still in memory, so doesn't use checkpoints.

### Webhooks
For all types of runs, langgraph cloud supports completion webhooks. When you create the run you can pass a webhook URL to be called when the completes (successfully or not). This is especially useful for background runs and cron jobs, as the webhook can give you an indication the run has completed and you can perform further actions for your appilcation.

# Cloud Concepts
This page describes the high-level concepts of the LangGraph Cloud deployment.
## Deployment
A deployment is an instance of a LangGraph API. A single deployment can have many [revisions](#revision). When a deployment is created, all of the necessary infrastructure (e.g. database, containers, secrets store) are automatically provisioned. See the [architecture diagram](#architecture) below for more details.
See the [how-to guide](../deployment/cloud.md#create-new-deployment) for creating a new deployment.
## Revision
A revision is an iteration of a [deployment](#deployment). When a new deployment is created, an initial revision is automatically created. To deploy new code changes or update environment variable configurations for a deployment, a new revision must be created. When a revision is created, a new container image is built automatically.
See the [how-to guide](../deployment/cloud.md#create-new-revision) for creating a new revision.
## Asynchronous Deployment
Infrastructure for [deployments](#deployment) and [revisions](#revision) are provisioned and deployed asynchronously. They are not deployed immediately after submission. Currently, deployment can take up to several minutes.
## Architecture
!!! warning "Subject to Change"
The LangGraph Cloud deployment architecture may change in the future.

# How to test a LangGraph app locally
This guide assumes you have a LangGraph app correctly set up with a proper configuration file and a corresponding compiled graph, and that you have a proper LangChain API key.
Testing locally ensures that there are no errors or conflicts with Python dependencies and confirms that the configuration file is specified correctly.
## Setup
Install the proper packages:
```shell
pip install langgraph-cli
```
Ensure you have an API key, which you can create from the LangSmith UI (Settings > API Keys). This is required to authenticate that you have LangGraph Cloud access. After you have saved the key to a safe place, place the following line in your `.env` file:
```python
LANGCHAIN_API_KEY = *********
```
## Start the API server
Once you have downloaded the CLI, you can run the following command to start the API server for local testing:
```shell
langgraph up
```
This will start up the LangGraph API server locally. If this runs successfully, you should see something like:
```shell
Ready!
- API: http://localhost:8123
2024-06-26 19:20:41,056:INFO:uvicorn.access 127.0.0.1:44138 - "GET /ok HTTP/1.1" 200
```
### Interact with the server
We can now interact with the API server using the LangGraph SDK. First, we need to start our client, select our assistant (in this case a graph we called "agent", make sure to select the proper assistant you wish to test).
=== "Python"
```python
from langgraph_sdk import get_client
# only pass the url argument to get_client() if you changed the default port when calling langgraph up
client = get_client()
assistant_id = "agent"
thread = await client.threads.create()
```
=== "Javascript"
```js
import { Client } from "@langchain/langgraph-sdk";
// only set the apiUrl if you changed the default port when calling langgraph up
const client = new Client();
const assistantId = "agent"
const thread = await client.threads.create();
```
Now we can invoke our graph to ensure it is working. Make sure to change the input to match the proper schema for your graph.

If your graph works correctly, you should see your graph output displayed in the console. Of course, there are many more ways you might need to test your graph, for a full list of commands you can send with the SDK, see the [Python](https://langchain-ai.github.io/langgraph/cloud/reference/sdk/python_sdk_ref/) and [JS/TS](https://langchain-ai.github.io/langgraph/cloud/reference/sdk/js_ts_sdk_ref/) references.

## Enqueue
This guide assumes knowledge of what double-texting is, which you can learn about in the [double-texting conceptual guide](../concepts/api.md#double-texting).
The guide covers the `enqueue` option for double texting, which adds the interruptions to a queue and executes them in the order they are received by the client. Below is a quick example of using the `enqueue` option.
First, we will define a quick helper function for printing out JS model outputs (you can skip this if using Python):
```js
function prettyPrint(m) {
const padded = " " + m['type'] + " ";
const sepLen = Math.floor((80 - padded.length) / 2);
const sep = "=".repeat(sepLen);
const secondSep = sep + (padded.length % 2 ? "=" : "");
console.log(`${sep}${padded}${secondSep}`);
console.log("\n\n");
console.log(m.content);
}
```
Then, let's import our required packages and instantiate our client, assistant, and thread.
=== "Python"
```python
import asyncio
import httpx
from langchain_core.messages import convert_to_messages
from langgraph_sdk import get_client
client = get_client(url="whatever-your-deployment-url-is")
assistant_id = "agent"
thread = await client.threads.create()
```
=== "Javascript"
```js
import { Client } from "@langchain/langgraph-sdk";
const client = new Client({ apiUrl:"whatever-your-deployment-url-is" });
const assistantId = "agent";
const thread = await client.threads.create();
```
Now let's start two runs, with the second interrupting the first one with a multitask strategy of "enqueue":
=== "Python"
```python
first_run = await client.runs.create(
thread["thread_id"],
assistant_id,
input={"messages": [{"role": "human", "content": "what's the weather in sf?"}]},
)
second_run = await client.runs.create(
thread["thread_id"],
assistant_id,
input={"messages": [{"role": "human", "content": "what's the weather in nyc?"}]},
multitask_strategy="enqueue",
)
```
=== "Javascript"
```js
const firstRun = await client.runs.create(
thread["thread_id"],
assistantId,
input={"messages": [{"role": "human", "content": "what's the weather in sf?"}]},
)
const secondRun = await client.runs.create(
thread["thread_id"],
assistantId,
input={"messages": [{"role": "human", "content": "what's the weather in nyc?"}]},
multitask_strategy="enqueue",
)
```
Verify that the thread has data from both runs:
=== "Python"
```python
# wait until the second run completes
await client.runs.join(thread["thread_id"], second_run["run_id"])
state = await client.threads.get_state(thread["thread_id"])
for m in convert_to_messages(state["values"]["messages"]):
m.pretty_print()
```
=== "Javascript"
```js
await client.runs.join(thread["thread_id"], secondRun["run_id"]);
const state = await client.threads.getState(thread["thread_id"]);
for (const m of state["values"]["messages"]) {
prettyPrint(m);
}
```

# How to Add Breakpoints
When creating LangGraph agents, it is often nice to add a human-in-the-loop component.
This can be helpful when giving them access to tools.
Often in these situations you may want to manually approve an action before taking.
This can be in several ways, but the primary supported way is to add an "interrupt" before a node is executed.
This interrupts execution at that node.
You can then resume from that spot to continue.
## Setup
### Code for your graph
In this how-to we use a simple ReAct style hosted graph (you can see the full code for defining it [here](../../how-tos/human_in_the_loop/breakpoints.ipynb)). The important thing is that there are two nodes (one named `agent` that calls the LLM, and one named `action` that calls the tool), and a routing function from `agent` that determines whether to call `action` next or just end the graph run (the `action` node always calls the `agent` node after execution).
### SDK Initialization
=== "Python"
```python
from langgraph_sdk import get_client
client = get_client(url="whatever-your-deployment-url-is")
assistant_id = "agent"
thread = await client.threads.create()
```
=== "Javascript"
```js
import { Client } from "@langchain/langgraph-sdk";
const client = new Client({ apiUrl:"whatever-your-deployment-url-is" });
const assistantId = "agent"
const thread = await client.threads.create();
```
## Adding a breakpoint
We now want to add a breakpoint in our graph run, which we will do before a tool is called.
We can do this by adding `interrupt_before=["action"]`, which tells us to interrupt before calling the action node.
We can do this either when compiling the graph or when kicking off a run.
Here we will do it when kicking of a run, if you would like to to do it at compile time you need to edit the python file where your graph is defined and add the `interrupt_before` parameter when you call `.compile`.
First let's access our hosted LangGraph instance through the SDK:
And, now let's compile it with a breakpoint before the tool node:
=== "Python"
```python
input = {"messages": [{"role": "human", "content": "what's the weather in sf"}]}
async for chunk in client.runs.stream(
thread["thread_id"],
assistant_id,
input=input,
stream_mode="updates",
interrupt_before=["action"],
):
print(f"Receiving new event of type: {chunk.event}...")
print(chunk.data)
print("\n\n")
```
=== "Javascript"
```js
const input = { "messages": [{ "role": "human", "content": "what's the weather in sf"}] }
const streamResponse = client.runs.stream(
thread["thread_id"],
assistantId,
{
input: input,
streamMode: "updates",
interruptBefore: ["action"],
}
);
for await (const chunk of streamResponse) {
console.log(`Receiving new event of type: ${chunk.event}...`);
console.log(chunk.data);
console.log("\n\n");
}
```
Output:

# How to Edit State of a Deployed Graph
When creating LangGraph agents, it is often nice to add a human-in-the-loop component. This can be helpful when giving them access to tools. Often in these situations you may want to edit the graph state before continuing (for example, to edit what tool is being called, or how it is being called).
This can be in several ways, but the primary supported way is to add an "interrupt" before a node is executed. This interrupts execution at that node. You can then use update_state to update the state, and then resume from that spot to continue.
## Setup
We are not going to show the full code for the graph we are hosting, but you can see it [here](../../how-tos/human_in_the_loop/edit-graph-state.ipynb#build-the-agent) if you want to. Once this graph is hosted, we are ready to invoke it and wait for user input.
### SDK initialization
First, we need to setup our client so that we can communicate with our hosted graph:
=== "Python"
```python
from langgraph_sdk import get_client
client = get_client(url="whatever-your-deployment-url-is")
assistant_id = "agent"
thread = await client.threads.create()
```
=== "Javascript"
```js
import { Client } from "@langchain/langgraph-sdk";
const client = new Client({ apiUrl:"whatever-your-deployment-url-is" });
const assistantId = "agent";
const thread = await client.threads.create();
```
## Editing state
### Initial invocation
Now let's invoke our graph, making sure to interrupt before the `action` node.
=== "Python"
```python
input = { 'messages':[{ "role":"user", "content":"search for weather in SF" }] }
async for chunk in client.runs.stream(
thread["thread_id"],
assistant_id,
input=input,
stream_mode="updates",
interrupt_before=["action"],
):
if chunk.data and chunk.event != "metadata":
print(chunk.data)
```
=== "Javascript"
```js
const input = {"messages": [{ "role": "human", "content": "search for weather in SF"}] }
const streamResponse = client.runs.stream(
thread["thread_id"],
assistantId,
{
input: input,
streamMode: "updates",
interruptBefore: ["action"],
}
);
for await (const chunk of streamResponse) {
if (chunk.data && chunk.event !== "metadata") {
console.log(chunk.data);
}
}
```
Output:
{'agent': {'messages': [{'content': [{'text': "Certainly! I'll search for the current weather in San Francisco for you using the search function. Here's how I'll do that:", 'type': 'text'}, {'id': 'toolu_01KEJMBFozSiZoS4mAcPZeqQ', 'input': {'query': 'current weather in San Francisco'}, 'name': 'search', 'type': 'tool_use'}], 'additional_kwargs': {}, 'response_metadata': {}, 'type': 'ai', 'name': None, 'id': 'run-6dbb0167-f8f6-4e2a-ab68-229b2d1fbb64', 'example': False, 'tool_calls': [{'name': 'search', 'args': {'query': 'current weather in San Francisco'}, 'id': 'toolu_01KEJMBFozSiZoS4mAcPZeqQ'}], 'invalid_tool_calls': [], 'usage_metadata': None}]}}
### Edit the state
Now, let's assume we actually meant to search for the weather in Sidi Frej (another city with the initials SF). We can edit the state to properly reflect that:
=== "Python"
```python
# First, lets get the current state
current_state = await client.threads.get_state(thread['thread_id'])
# Let's now get the last message in the state
# This is the one with the tool calls that we want to update
last_message = current_state['values']['messages'][-1]
# Let's now update the args for that tool call
last_message['tool_calls'][0]['args'] = {'query': 'current weather in Sidi Frej'}
# Let's now call `update_state` to pass in this message in the `messages` key
# This will get treated as any other update to the state
# It will get passed to the reducer function for the `messages` key
# That reducer function will use the ID of the message to update it
# It's important that it has the right ID! Otherwise it would get appended
# as a new message
await client.threads.update_state(thread['thread_id'], {"messages": last_message})
```
=== "Javascript"
```js
// First, lets get the current state
const currentState = await client.threads.getState(thread['thread_id']);
// Let's now get the last message in the state
// This is the one with the tool calls that we want to update
let lastMessage = currentState['values']['messages'][-1];
// Let's now update the args for that tool call
lastMessage['tool_calls'][0]['args'] = {'query': 'current weather in Sidi Frej'};
// Let's now call `update_state` to pass in this message in the `messages` key
// This will get treated as any other update to the state
// It will get passed to the reducer function for the `messages` key
// That reducer function will use the ID of the message to update it
// It's important that it has the right ID! Otherwise it would get appended
// as a new message
await client.threads.updateState(thread['thread_id'], {values:{"messages": lastMessage}});
```
Output:
{'configurable': {'thread_id': '88d58d3f-4151-47a9-a8e0-e42fdd3527b8',
'thread_ts': '1ef3274b-a809-6913-8002-91536ce6554d'}}
### Resume invocation
Now we can resume our graph run but with the updated state:
=== "Python"
```python
async for chunk in client.runs.stream(
thread["thread_id"],
assistant_id,
input=None,
stream_mode="updates",
):
if chunk.data and chunk.event != "metadata":
print(chunk.data)
```
=== "Javascript"
```js
const streamResponse = client.runs.stream(
thread["thread_id"],
assistantId,
{
input: null,
streamMode: "updates",
}
);
for await (const chunk of streamResponse) {
if (chunk.data && chunk.event !== "metadata") {
console.log(chunk.data);
}
}
```
Output:

Result: It\'s sunny in San Francisco, but you better look out if you\'re a Gemini 😈."]', 'additional_kwargs': {}, 'response_metadata': {}, 'type': 'tool', 'name': 'search', 'id': '1161b8d1-bee4-4188-9be8-698aecb69f10', 'tool_call_id': 'toolu_01KEJMBFozSiZoS4mAcPZeqQ'}]}}
{'agent': {'messages': [{'content': [{'text': 'I apologize for the confusion in my search query.

{'agent': {'messages': [{'content': "Now, based on the search results, I can provide you with information about the current weather in San Francisco:\n\nThe weather in San Francisco is currently sunny. \n\nIt's worth noting that the search result included an unusual comment about Gemini, which doesn't seem directly related to the weather. This might be due to the search engine including some astrological information or a joke in its results. However, for the purpose of weather information, we can focus on the fact that it's sunny in San Francisco right now.\n\nIs there anything else you'd like to know about the weather in San Francisco or any other location?", 'additional_kwargs': {}, 'response_metadata': {}, 'type': 'ai', 'name': None, 'id': 'run-227a042b-dd97-476e-af32-76a3703af5d8', 'example': False, 'tool_calls': [], 'invalid_tool_calls': [], 'usage_metadata': None}]}}
As you can see it now looks up the current weather in Sidi Frej (although our dummy search node still returns results for SF because we don't actually do a search in this example, we just return the same "It's sunny in San Francisco ..." result every time).

# How to Replay and Branch from Prior States
With LangGraph Cloud you have the ability to return to any of your prior states and either re-run the graph to reproduce issues noticed during testing, or branch out in a different way from what was originally done in the prior states. In this guide we will show a quick example of how to rerun past states and how to branch off from previous states as well.
## Setup
We are not going to show the full code for the graph we are hosting, but you can see it [here](../../how-tos/human_in_the_loop/time-travel.ipynb#build-the-agent) if you want to. Once this graph is hosted, we are ready to invoke it and wait for user input.
### SDK initialization
First, we need to setup our client so that we can communicate with our hosted graph:
=== "Python"
```python
from langgraph_sdk import get_client
client = get_client(url="whatever-your-deployment-url-is")
assistant_id = "agent"
thread = await client.threads.create()
```

```js
import { Client } from "@langchain/langgraph-sdk";
const client = new Client({ apiUrl:"whatever-your-deployment-url-is" });
const assistantId = agent;
const thread = await client.threads.create();
```
## Replay a state
### Initial invocation
Before replaying a state - we need to create states to replay from! In order to do this, let's invoke our graph with a simple message:
=== "Python"
```python
input = { 'messages':[{ "role":"user", "content":"Please search the weather in SF" }] }
async for chunk in client.runs.stream(
thread["thread_id"],
assistant_id, # graph_id
input=input,
stream_mode="updates",
):
if chunk.data and chunk.event != "metadata":
print(chunk.data)
```
=== "Javascript"
```js
const input = {"messages": [{ "role": "human", "content": "Please search the weather in SF"}] }
const streamResponse = client.runs.stream(
thread["thread_id"],
assistantId,
{
input: input,
streamMode: "updates",
}
);
for await (const chunk of streamResponse) {
if (chunk.data && chunk.event !== "metadata") {
console.log(chunk.data);
}
}
```
Output:
{'agent': {'messages': [{'content': [{'text': "Certainly! I'll use the search function to look up the current weather in San Francisco for you. Let me do that now.", 'type': 'text'}, {'id': 'toolu_011vroKUtWU7SBdrngpgpFMn', 'input': {'query': 'current weather in San Francisco'}, 'name': 'search', 'type': 'tool_use'}], 'additional_kwargs': {}, 'response_metadata': {}, 'type': 'ai', 'name': None, 'id': 'run-ee639877-d97d-40f8-96dc-d0d1ae22d203', 'example': False, 'tool_calls': [{'name': 'search', 'args': {'query': 'current weather in San Francisco'}, 'id': 'toolu_011vroKUtWU7SBdrngpgpFMn'}], 'invalid_tool_calls': [], 'usage_metadata': None}]}}
{'action': {'messages': [{'content': '["I looked up: current weather in San Francisco.

{'agent': {'messages': [{'content': "Based on the search results, I can provide you with information about the current weather in San Francisco:\n\nThe weather in San Francisco is currently sunny.

This might be due to the search engine including some astrological information or a joke in its results. However, for the purpose of answering your question about the weather, we can focus on the fact that it's sunny in San Francisco.\n\nIf you need any more specific information about the weather in San Francisco, such as temperature, wind speed, or forecast for the coming days, please let me know, and I'd be happy to search for that information for you.", 'additional_kwargs': {}, 'response_metadata': {}, 'type': 'ai', 'name': None, 'id': 'run-dbac539a-33c8-4f0c-9e20-91f318371e7c', 'example': False, 'tool_calls': [], 'invalid_tool_calls': [], 'usage_metadata': None}]}}
Now let's get our list of states, and invoke from the third state (right before the tool get called):
=== "Python"
```python
states = await client.threads.get_history(thread['thread_id'])
# We can confirm that this state is correct by checking the 'next' attribute and seeing that it is the tool call node
state_to_replay = states[2]
print(state_to_replay['next'])
```
=== "Javascript"
```js
const states = await client.threads.getHistory(thread['thread_id']);
// We can confirm that this state is correct by checking the 'next' attribute and seeing that it is the tool call node
const stateToReplay = states[2];
console.log(stateToReplay['next']);
```
Output:
['action']
To rerun from a state, we need to pass in the `checkpoint_id` into the config of the run like follows:
=== "Python"
```python
async for chunk in client.runs.stream(
thread["thread_id"],
assistant_id, # graph_id

console.log(chunk.data);

```
Output:

As we can see, the graph restarted from the tool node with the same input as our original graph run.
## Branch off from previous state
Using LangGraph's checkpointing, you can do more than just replay past states. You can branch off previous locations to let the agent explore alternate trajectories or to let a user "version control" changes in a workflow.
Let's show how to do this to edit the state at a particular point in time. Let's update the state to change the input to the tool
=== "Python"
```python
# Let's now get the last message in the state
# This is the one with the tool calls that we want to update
last_message = state_to_replay['values']['messages'][-1]
# Let's now update the args for that tool call
last_message['tool_calls'][0]['args'] = {'query': 'current weather in SF'}
new_state = await client.threads.update_state(thread['thread_id'],{"messages":[last_message]},checkpoint_id=state_to_replay['checkpoint_id'])
```
=== "Javascript"
```js
// Let's now get the last message in the state
// This is the one with the tool calls that we want to update
let lastMessage = stateToReplay['values']['messages'][-1];
// Let's now update the args for that tool call
lastMessage['tool_calls'][0]['args'] = {'query': 'current weather in SF'};
const newState = await client.threads.updateState(thread['thread_id'],{values:{"messages":[lastMessage]},checkpointId:stateToReplay['checkpoint_id']});
```
Now we can rerun our graph with this new config, starting from the `new_state`, which is a branch of our `state_to_replay`:
=== "Python"
```python
async for chunk in client.runs.stream(
thread["thread_id"],
assistant["assistant_id"], # graph_id
input=None,
stream_mode="updates",
config={"configurable": {"thread_ts": new_state['configurable']['thread_ts']}}
):
if chunk.data and chunk.event != "metadata":
print(chunk.data)
```
=== "Javascript"
```js
const streamResponse = client.runs.stream(
thread["thread_id"],
assistant["assistant_id"],
{
input: null,
streamMode: "updates",
config: {"configurable": {"thread_ts": newState['configurable']['thread_ts']}},
}
);
for await (const chunk of streamResponse) {
if (chunk.data && chunk.event !== "metadata") {
console.log(chunk.data);
}
}
```
Output:
{'action': {'messages': [{'content': '["I looked up: current weather in SF. Result: It\'s sunny in San Francisco, but you better look out if you\'re a Gemini 😈."]', 'additional_kwargs': {}, 'response_metadata': {}, 'type': 'tool', 'name': 'search', 'id': '2baf9941-4fda-4081-9f87-d76795d289f1', 'tool_call_id': 'toolu_011vroKUtWU7SBdrngpgpFMn'}]}}
{'agent': {'messages': [{'content': "Based on the search results, I can provide you with information about the current weather in San Francisco (SF):\n\nThe weather in San Francisco is currently sunny. This means it's a clear day with plenty of sunshine. \n\nIt's worth noting that the specific temperature wasn't provided in the search result, but sunny weather in San Francisco typically means comfortable temperatures. San Francisco is known for its mild climate, so even on sunny days, it's often not too hot.\n\nThe search result also included a playful reference to astrological signs, mentioning Gemini. However, this is likely just a joke or part of the search engine's presentation and not related to the actual weather conditions.\n\nIs there any specific information about the weather in San Francisco you'd like to know more about? I'd be happy to perform another search if you need details on temperature, wind conditions, or the forecast for the coming days.", 'additional_kwargs': {}, 'response_metadata': {}, 'type': 'ai', 'name': None, 'id': 'run-a83de52d-ed18-4402-9384-75c462485743', 'example': False, 'tool_calls': [], 'invalid_tool_calls': [], 'usage_metadata': None}]}}
As we can see, the search query changed from San Francisco to SF, just as we had hoped!

# How to Wait for User Input
One of the main human-in-the-loop interaction patterns is waiting for human input. A key use case involves asking the user clarifying questions. One way to accomplish this is simply go to the `END` node and exit the graph. Then, any user response comes back in as fresh invocation of the graph. This is basically just creating a chatbot architecture.
The issue with this is it is tough to resume back in a particular point in the graph. Often times the agent is halfway through some process, and just needs a bit of a user input. Although it is possible to design your graph in such a way where you have a `conditional_entry_point` to route user messages back to the right place, that is not super scalable (as it essentially involves having a routing function that can end up almost anywhere).
A separate way to do this is to have a node explicitly for getting user input. This is easy to implement in a notebook setting - you just put an `input()` call in the node. But that isn't exactly production ready.
Luckily, LangGraph makes it possible to do similar things in a production way. The basic idea is:
- Set up a node that represents human input. This can have specific incoming/outgoing edges (as you desire). There shouldn't actually be any logic inside this node.
- Add a breakpoint before the node. This will stop the graph before this node executes (which is good, because there's no real logic in it anyways)
- Use `.update_state` to update the state of the graph. Pass in whatever human response you get. The key here is to use the `as_node` parameter to apply this update **as if you were that node**. This will have the effect of making it so that when you resume execution next it resumes as if that node just acted, and not from the beginning.
## Setup
We are not going to show the full code for the graph we are hosting, but you can see it [here](../../how-tos/human_in_the_loop/wait-user-input.ipynb#build-the-agent) if you want to. Once this graph is hosted, we are ready to invoke it and wait for user input.
### SDK initialization
First, we need to setup our client so that we can communicate with our hosted graph:
=== "Python"
```python
from langgraph_sdk import get_client
client = get_client(url="whatever-your-deployment-url-is")
assistant_id = "agent"
thread = await client.threads.create()
```
=== "Javascript"
```js
import { Client } from "@langchain/langgraph-sdk";
const client = new Client({ apiUrl:"whatever-your-deployment-url-is" });
const assistantId = "agent";
const thread = await client.threads.create();
```
## Waiting for user input
### Initial invocation
Now, let's invoke our graph by interrupting before `ask_human` node:
=== "Python"
```python
input = { 'messages':[{ "role":"user", "content":"Use the search tool to ask the user where they are, then look up the weather there" }] }
async for chunk in client.runs.stream(
thread["thread_id"],
assistant_id,
input=input,
stream_mode="updates",
interrupt_before=["ask_human"],
):
if chunk.data and chunk.event != "metadata":
print(chunk.data)
```
=== "Javascript"
```js
const input = { "messages":[{ "role":"human", "content": "Use the search tool to ask the user where they are, then look up the weather there"}] }
const streamResponse = client.runs.stream(
thread["thread_id"],
assistantId,
{
input: input,
streamMode: "updates",
interruptBefore: ["ask_human"],
}
);
for await (const chunk of streamResponse) {
if (chunk.data && chunk.event !== "metadata") {
console.log(chunk.data);
}
}
```
Output:
{'agent': {'messages': [{'content': [{'text': "Certainly! I'll use the AskHuman function to ask the user about their location, and then I'll use the search function to look up the weather for that location. Let's start by asking the user where they are.", 'type': 'text'}, {'id': 'toolu_01RFahzYPvnPWTb2USk2RdKR', 'input': {'question': 'Where are you currently located?'}, 'name': 'AskHuman', 'type': 'tool_use'}], 'additional_kwargs': {}, 'response_metadata': {}, 'type': 'ai', 'name': None, 'id': 'run-a8422215-71d3-4093-afb4-9db141c94ddb', 'example': False, 'tool_calls': [{'name': 'AskHuman', 'args': {'question': 'Where are you currently located?'}, 'id': 'toolu_01RFahzYPvnPWTb2USk2RdKR'}], 'invalid_tool_calls': [], 'usage_metadata': None}]}}
### Adding user input to state
We now want to update this thread with a response from the user. We then can kick off another run.
Because we are treating this as a tool call, we will need to update the state as if it is a response from a tool call. In order to do this, we will need to check the state to get the ID of the tool call.
=== "Python"
```python
state = await client.threads.get_state(thread['thread_id'])
tool_call_id = state['values']['messages'][-1]['tool_calls'][0]['id']
# We now create the tool call with the id and the response we want
tool_message = [{"tool_call_id": tool_call_id, "type": "tool", "content": "san francisco"}]
await client.threads.update_state(thread['thread_id'], {"messages": tool_message}, as_node="ask_human")
```
=== "Javascript"
```js
const state = await client.threads.getState(thread['thread_id']);
const toolCallId = state['values']['messages'][-1]['tool_calls'][0]['id'];
# We now create the tool call with the id and the response we want
const toolMessage = [{"tool_call_id": toolCallId, "type": "tool", "content": "san francisco"}];
await client.threads.updateState(thread['thread_id'], {values: {"messages": toolMessage}, asNode:"ask_human"})
```
Output:
{'configurable': {'thread_id': '10d0ee61-db47-48fc-a58c-109a1e68cd73',
'thread_ts': '1ef32729-3cc3-6647-8002-14dcb621b46e'}}
### Invoking after receiving human input
We can now tell the agent to continue. We can just pass in None as the input to the graph, since no additional input is needed:
=== "Python"
```python
async for chunk in client.runs.stream(
thread["thread_id"],
assistant_id, # graph_id
input=None,
stream_mode="updates",
):
if chunk.data and chunk.event != "metadata":
print(chunk.data)
```
=== "Javascript"
```js
const streamResponse = client.runs.stream(
thread["thread_id"],
assistantId,
{
input: null,
streamMode: "updates",
}
);
for await (const chunk of streamResponse) {
if (chunk.data && chunk.event !== "metadata") {
console.log(chunk.data);
}
}
```
Output:
{'agent': {'messages': [{'content': [{'text': "Thank you for letting me know that you're in San Francisco. Now, I'll use the search function to look up the weather in San Francisco.", 'type': 'text'}, {'id': 'toolu_01K57ofmgG2wyJ8tYJjbq5k7', 'input': {'query': 'current weather in San Francisco'}, 'name': 'search', 'type': 'tool_use'}], 'additional_kwargs': {}, 'response_metadata': {}, 'type': 'ai', 'name': None, 'id': 'run-241baed7-db5e-44ce-ac3c-56431705c22b', 'example': False, 'tool_calls': [{'name': 'search', 'args': {'query': 'current weather in San Francisco'}, 'id': 'toolu_01K57ofmgG2wyJ8tYJjbq5k7'}], 'invalid_tool_calls': [], 'usage_metadata': None}]}}
{'action': {'messages': [{'content': '["I looked up: current weather in San Francisco. Result: It\'s sunny in San Francisco, but you better look out if you\'re a Gemini 😈."]', 'additional_kwargs': {}, 'response_metadata': {}, 'type': 'tool', 'name': 'search', 'id': '8b699b95-8546-4557-8e66-14ea71a15ed8', 'tool_call_id': 'toolu_01K57ofmgG2wyJ8tYJjbq5k7'}]}}
{'agent': {'messages': [{'content': "Based on the search results, I can provide you with information about the current weather in San Francisco:\n\nThe weather in San Francisco is currently sunny. It's a beautiful day in the city! \n\nHowever, I should note that the search result included an unusual comment about Gemini zodiac signs.

# How-to Guides
Welcome to the LangGraph Cloud how-to guides! These guides provide practical, step-by-step instructions for accomplishing key tasks in LangGraph Cloud.
## Deployment
LangGraph Cloud gives you best in class observability, testing, and hosting services. Read more about them in these how to guides:
- [How to set up app for deployment (requirements.txt)](../deployment/setup.md)
- [How to set up app for deployment (pyproject.toml)](../deployment/setup_pyproject.md)
- [How to test locally](../deployment/test_locally.md)
- [How to deploy to LangGraph cloud](../deployment/cloud.md)
- [How to self-host](../deployment/self_hosted.md)
## Streaming
Streaming the results of your LLM application is vital for ensuring a good user experience, especially when your graph may call multiple models and take a long time to fully complete a run. Read about how to stream values from your graph in these how to guides:
- [How to stream values](./stream_values.md)
- [How to stream updates](./stream_updates.md)
- [How to stream messages](./stream_messages.md)
- [How to stream events](./stream_events.md)
- [How to stream in debug mode](./stream_debug.md)
- [How to stream multiple modes](./stream_multiple.md)
## Double-texting
Graph execution can take a while, and sometimes users may change their mind about the input they wanted to send before their original input has finished running. For example, a user might notice a typo in their original request and will edit the prompt and resend it. Deciding what to do in these cases is important for ensuring a smooth user experience and preventing your graphs from behaving in unexpected ways. The following how-to guides provide information on the various options LangGraph Cloud gives you for dealing with double-texting:
- [How to use the interrupt option](./interrupt_concurrent.md)
- [How to use the rollback option](./rollback_concurrent.md)
- [How to use the reject option](./reject_concurrent.md)
- [How to use the enqueue option](./enqueue_concurrent.md)
## Human-in-the-loop
When creating complex graphs, leaving every decision up to the LLM can be dangerous, especially when the decisions involve invoking certain tools or accessing specific documents. To remedy this, LangGraph allows you to insert human-in-the-loop behavior to ensure your graph does not have undesired outcomes. Read more about the different ways you can add human-in-the-loop capabilities to your LangGraph Cloud projects in these how-to guides:
- [How to add a breakpoint](./human_in_the_loop_breakpoint.md)
- [How to wait for user input](./human_in_the_loop_user_input.md)
- [How to edit graph state](./human_in_the_loop_edit_state.md)
- [How to replay and branch from prior states](./human_in_the_loop_time_travel.md)
## LangGraph Studio
LangGraph Studio is a built-in UI for visualizing, testing, and debugging your agents.
- [How to enter LangGraph Studio](./test_deployment.md)
- [How to test your graph in LangGraph Studio](./invoke_studio.md)
- [Interact with threads in LangGraph Studio](./threads_studio.md)
## Different Types of Runs:
LangGraph Cloud supports multiple types of runs besides streaming runs.
- [How to run an agent in the background](cloud_examples/background_run.ipynb)
- [How to run multiple agents in the same thread](cloud_examples/same-thread.ipynb)
- [How to create cron jobs](cloud_examples/cron_jobs.ipynb)
- [How to create stateless runs](cloud_examples/stateless_runs.ipynb)
## Other
Other guides that may prove helpful!
- [How to configure agents](cloud_examples/configuration_cloud.ipynb)
- [How to convert LangGraph calls to LangGraph cloud calls](cloud_examples/langgraph_to_langgraph_cloud.ipynb)
- [How to integrate webhooks](cloud_examples/webhooks.ipynb)

## Interrupt
This guide assumes knowledge of what double-texting is, which you can learn about in the [double-texting conceptual guide](../concepts/api.md#double-texting).
The guide covers the `interrupt` option for double texting, which interrupts the prior run of the graph and starts a new one with the double-text. This option does not delete the first run, but rather keeps it in the database but sets its status to `interrupted`. Below is a quick example of using the `interrupt` option.
First, we will define a quick helper function for printing out JS model outputs (you can skip this if using Python):
```js
function prettyPrint(m) {
const padded = " " + m['type'] + " ";
const sepLen = Math.floor((80 - padded.length) / 2);
const sep = "=".repeat(sepLen);
const secondSep = sep + (padded.length % 2 ? "=" : "");
console.log(`${sep}${padded}${secondSep}`);
console.log("\n\n");
console.log(m.content);
}
```
Now, let's import our required packages and instantiate our client, assistant, and thread.
=== "Python"
```python
import asyncio
from langchain_core.messages import convert_to_messages
from langgraph_sdk import get_client
client = get_client(url="whatever-your-deployment-url-is")
assistant_id = "agent"
thread = await client.threads.create()
```
=== "Javascript"
```js
import { Client } from "@langchain/langgraph-sdk";
const client = new Client({ apiUrl:"whatever-your-deployment-url-is" });
const assistantId = "agent";
const thread = await client.threads.create();
```
Now we can start our two runs and join the second on euntil it has completed:
=== "Python"
```python
# the first run will be interrupted
interrupted_run = await client.runs.create(
thread["thread_id"],
assistant_id,
input={"messages": [{"role": "human", "content": "what's the weather in sf?"}]},
)
await asyncio.sleep(2)
run = await client.runs.create(
thread["thread_id"],
assistant_id,
input={"messages": [{"role": "human", "content": "what's the weather in nyc?"}]},
multitask_strategychrom="interrupt",
)
# wait until the second run completes
await client.runs.join(thread["thread_id"], run["run_id"])
```
=== "Javascript"
```js
// the first run will be interrupted
let interruptedRun = await client.runs.create(
thread["thread_id"],
assistantId,
{ input: { messages: [{ role: "human", content: "what's the weather in sf?" }] } }
);
await new Promise(resolve => setTimeout(resolve, 2000));
let run = await client.runs.create(
thread["thread_id"],
assistantId,
{
input: { messages: [{ role: "human", content: "what's the weather in nyc?" }] },
multitaskStrategy: "interrupt"
}
);
// wait until the second run completes
await client.runs.join(thread["thread_id"], run["run_id"]);
```
We can see that the thread has partial data from the first run + data from the second run
=== "Python"
```python
state = await client.threads.get_state(thread["thread_id"])
for m in convert_to_messages(state["values"]["messages"]):
m.pretty_print()
```
=== "Javascript"
```js
const state = await client.threads.getState(thread["thread_id"]);
for (const m of state['values']['messages']) {
prettyPrint(m);
}
```

The search results provide weather forecasts and information for New York City. Based on the top result from AccuWeather, here are some key details about the weather in NYC:
- This is a monthly weather forecast for New York City for the month of June.
- It includes daily high and low temperatures to help plan ahead.
- Historical averages for June in NYC are also provided as a reference point.
- More detailed daily or hourly forecasts with precipitation chances, humidity, wind, etc. can be found by visiting the AccuWeather page.
So in summary, the search provides a convenient overview of the expected weather conditions in New York City over the next month to give you an idea of what to prepare for if traveling or making plans there. Let me know if you need any other details!

## Reject
This guide assumes knowledge of what double-texting is, which you can learn about in the [double-texting conceptual guide][double-texting].
The guide covers the `reject` option for double texting, which rejects the new run of the graph by throwing an error and continues with the original run until completion. Below is a quick example of using the `reject` option.
First, we will define a quick helper function for printing out JS model outputs (you can skip this if using Python):
```js
function prettyPrint(m) {
const padded = " " + m['type'] + " ";
const sepLen = Math.floor((80 - padded.length) / 2);
const sep = "=".repeat(sepLen);
const secondSep = sep + (padded.length % 2 ? "=" : "");
console.log(`${sep}${padded}${secondSep}`);
console.log("\n\n");
console.log(m.content);
}
```
Now, let's import our required packages and instantiate our client, assistant, and thread.
=== "Python"
```python
import httpx
from langchain_core.messages import convert_to_messages
from langgraph_sdk import get_client
client = get_client(url="whatever-your-deployment-url-is")
assistant_id = "agent"
thread = await client.threads.create()
```

```js
import { Client } from "@langchain/langgraph-sdk";
const client = new Client({ apiUrl:"whatever-your-deployment-url-is" });
const assistantId = "agent";
const thread = await client.threads.create();
```
Now we can run a thread and try to run a second one with the "reject" option, which should fail since we have already started a run:
=== "Python"
```python
run = await client.runs.create(
thread["thread_id"],
assistant_id,
input={"messages": [{"role": "human", "content": "what's the weather in sf?"}]},
)
try:
await client.runs.create(
thread["thread_id"],
assistant_id,
input={
"messages": [{"role": "human", "content": "what's the weather in nyc?"}]
},
multitask_strategy="reject",
)
except httpx.HTTPStatusError as e:
print("Failed to start concurrent run", e)
```
=== "Javascript"
```js
const run = await client.runs.create(
thread["thread_id"],
assistantId,
input={"messages": [{"role": "human", "content": "what's the weather in sf?"}]},
);
try {
await client.runs.create(
thread["thread_id"],

================================== Ai Message ==================================
According to the search results from Tavily, the current weather in San Francisco is:
The average high temperature in San Francisco in June is around 65°F (18°C), with average lows around 54°F (12°C). June tends to be one of the cooler and foggier months in San Francisco due to the marine layer of fog that often blankets the city during the summer months.
Some key points about the typical June weather in San Francisco:
- Mild temperatures with highs in the 60s F and lows in the 50s F
- Foggy mornings that often burn off to sunny afternoons
- Little to no rainfall, as June falls in the dry season
- Breezy conditions, with winds off the Pacific Ocean
- Layers are recommended for changing weather conditions
So in summary, you can expect mild, foggy mornings giving way to sunny but cool afternoons in San Francisco this time of year. The marine layer keeps temperatures moderate compared to other parts of California in June.

## Rollback
This guide assumes knowledge of what double-texting is, which you can learn about in the [double-texting conceptual guide][double-texting].
The guide covers the `rollback` option for double texting, which interrupts the prior run of the graph and starts a new one with the double-text. This option is very similar to the `interrupt` option, but in this case the first run is completely deleted from the database and cannot be restarted. Below is a quick example of using the `rollback` option.
First, we will define a quick helper function for printing out JS model outputs (you can skip this if using Python):
```js
function prettyPrint(m) {
const padded = " " + m['type'] + " ";
const sepLen = Math.floor((80 - padded.length) / 2);
const sep = "=".repeat(sepLen);
const secondSep = sep + (padded.length % 2 ? "=" : "");
console.log(`${sep}${padded}${secondSep}`);
console.log("\n\n");
console.log(m.content);
}
```
Now, let's import our required packages and instantiate our client, assistant, and thread.
=== "Python"
```python
import asyncio
import httpx
from langchain_core.messages import convert_to_messages
from langgraph_sdk import get_client
client = get_client(url="whatever-your-deployment-url-is")
assistant_id = "agent"
thread = await client.threads.create()
```
=== "Javascript"
```js
import { Client } from "@langchain/langgraph-sdk";
const client = new Client({ apiUrl:"whatever-your-deployment-url-is" });
const assistantId = "agent";
const thread = await client.threads.create();
```
Now let's run a thread with the multitask parameter set to "rollback":
=== "Python"
```python
# the first run will be rolled back
rolled_back_run = await client.runs.create(
thread["thread_id"],
assistant_id,
input={"messages": [{"role": "human", "content": "what's the weather in sf?"}]},
)
await asyncio.sleep(2)
run = await client.runs.create(
thread["thread_id"],
assistant_id,
input={"messages": [{"role": "human", "content": "what's the weather in nyc?"}]},
multitask_strategy="rollback",
)
# wait until the second run completes
await client.runs.join(thread["thread_id"], run["run_id"])
```
=== "Javascript"
```js
// the first run will be interrupted
let rolledBackRun = await client.runs.create(
thread["thread_id"],
assistantId,
{ input: { messages: [{ role: "human", content: "what's the weather in sf?" }] } }
);
await new Promise(resolve => setTimeout(resolve, 2000));
let run = await client.runs.create(
thread["thread_id"],
assistant_id,
{
input: { messages: [{ role: "human", content: "what's the weather in nyc?" }] },
multitaskStrategy: "rollback"
}
);
// wait until the second run completes
await client.runs.join(thread["thread_id"], run["run_id"]);
```
We can see that the thread has data only from the second run
=== "Python"
```python
state = await client.threads.get_state(thread["thread_id"])
for m in convert_to_messages(state["values"]["messages"]):
m.pretty_print()
```
=== "Javascript"
```js
const state = await client.threads.getState(thread["thread_id"]);
for (const m of state['values']['messages']) {
prettyPrint(m);
}
```

# How to stream debug events
This guide covers how to stream debug events from your graph (`stream_mode="debug"`).
First let's set up our client and thread:
=== "Python"
```python
from langgraph_sdk import get_client
client = get_client(url="whatever-your-deployment-url-is")
# create thread
thread = await client.threads.create()
print(thread)
```
=== "Javascript"
```js
import { Client } from "@langchain/langgraph-sdk";
const client = new Client({ apiUrl:"whatever-your-deployment-url-is" });
// create thread
const thread = await client.threads.create();
console.log(thread)
```
Output:
{'thread_id': 'd0cbe9ad-f11c-443a-9f6f-dca0ae5a0dd3',
'created_at': '2024-06-21T22:10:27.696862+00:00',
'updated_at': '2024-06-21T22:10:27.696862+00:00',
'metadata': {}}
Streaming debug events produces responses containing `type` and `timestamp` keys. Debug events correspond to different steps in the graph's execution (e.g. `task`, `task_result`, `checkpoint`).
=== "Python"
```python
# create input
input = {
"messages": [
{
"role": "human",
"content": "What's the weather in SF?",
}
]
}
# stream debug
async for chunk in client.runs.stream(
thread_id=thread["thread_id"],
assistant_id="agent",
input=input,
stream_mode="debug",
):
print(f"Receiving new event of type: {chunk.event}...")
print(chunk.data)
print("\n\n")
```
=== "Javascript"
```js
// create input
const input = {
"messages": [
{
"role": "human",
"content": "What's the weather in SF?",
}
]
}
// stream debug
const streamResponse = client.runs.stream(
thread["thread_id"],
"agent",
{
input,
streamMode: "debug"
}
);
for await (const chunk of streamResponse) {
console.log(f"Receiving new event of type: {chunk.event}...")
console.log(chunk.data)
console.log("\n\n")
}
```

# How to stream events
This guide covers how to stream events from your graph (`stream_mode="events"`). Depending on the use case and user experience of your LangGraph application, your application may process event types differently.
=== "Python"
```python
from langgraph_sdk import get_client
client = get_client(url="whatever-your-deployment-url-is")
# create thread
thread = await client.threads.create()
print(thread)
```
=== "Javascript"
```js
import { Client } from "@langchain/langgraph-sdk";
const client = new Client({ apiUrl:"whatever-your-deployment-url-is" });
// create thread
const thread = await client.threads.create();
console.log(thread)
```
Output:
{'thread_id': '3f4c64e0-f792-4a5e-aa07-a4404e06e0bd',
'created_at': '2024-06-24T22:16:29.301522+00:00',
'updated_at': '2024-06-24T22:16:29.301522+00:00',
'metadata': {}}
Streaming events produces responses containing an `event` key (in addition to other keys such as `data`). See the LangChain [`Runnable.astream_events()` reference](https://api.python.langchain.com/en/latest/runnables/langchain_core.runnables.base.Runnable.html#langchain_core.runnables.base.Runnable.astream_events) for all event types.
=== "Python"
```python
# create input
input = {
"messages": [
{
"role": "human",
"content": "What's the weather in SF?",
}
]
}
# stream events
async for chunk in client.runs.stream(
thread_id=thread["thread_id"],
assistant_id="agent",
input=input,
stream_mode="events",
):
print(f"Receiving new event of type: {chunk.event}...")
print(chunk.data)
print("\n\n")
```
=== "Javascript"
```js
// create input
const input = {
"messages": [
{
"role": "human",
"content": "What's the weather in SF?",
}
]
}
// stream events
const streamResponse = client.runs.stream(
thread["thread_id"],
"agent",
{
input,
streamMode: "events"
}
);
for await (const chunk of streamResponse) {
console.log(f"Receiving new event of type: {chunk.event}...")
console.log(chunk.data)
console.log("\n\n")
}
```
Output:

## Token-by-Token Streaming
Token-by-token streaming can be implemented with the `events` streaming mode. The `on_chat_model_stream` event type should be processed to stream LLM responses token-by-token.
=== "Python"
```python
llm_response = ""
# stream token-by-token
async for chunk in client.runs.stream(
thread_id=thread["thread_id"],
assistant_id="agent",
input=input,
stream_mode="events",
):
if (
chunk.event == "events" and
chunk.data["event"] == "on_chat_model_stream"
):
llm_response += chunk.data["data"]["chunk"]["content"]
print(llm_response)
```
=== "Javascript"
```js
const llmResponse = "";
// stream events
const streamResponse = client.runs.stream(
thread["thread_id"],
"agent",
{
input,
streamMode: "events"
}
);
for await (const chunk of streamResponse) {
if (chunk.event === "events" && chunk.data.event === "on_chat_model_stream") {
llmResponse += chunk.data.data.chunk.content;
console.log(llmResponse);
}
}
```

# How to stream messages from your graph
LangGraph Cloud supports multiple streaming modes. The main ones are:
- `values`: This streaming mode streams back values of the graph. This is the **full state of the graph** after each node is called.
- `updates`: This streaming mode streams back updates to the graph. This is the **update to the state of the graph** after each node is called.
- `messages`: This streaming mode streams back messages - both complete messages (at the end of a node) as well as **tokens** for any messages generated inside a node. This mode is primarily meant for powering chat applications.
This guide covers `stream_mode="messages"`.
In order to use this mode, the state of the graph you are interacting with MUST have a `messages` key that is a list of messages.
E.g., the state should look something like:
=== "Python"
```python
from typing import TypedDict, Annotated
from langgraph.graph import add_messages
from langchain_core.messages import AnyMessage
class State(TypedDict):
messages: Annotated[list[AnyMessage], add_messages]
```
Alternatively, you can use an instance or subclass of `from langgraph.graph import MessagesState` (`MessagesState` is equivalent to the implementation above).
> [!NOTE]
> LangGraph Cloud only supports hosting graphs written in Python at the moment.
With `stream_mode="messages"` two things will be streamed back:
- It outputs messages produced by any chat model called inside (unless tagged in a special way)
- It outputs messages returned from nodes (to allow for nodes to return `ToolMessages` and the like
First let's set up our client and thread:
=== "Python"
```python
from langgraph_sdk import get_client
client = get_client(url="whatever-your-deployment-url-is")
# create thread
thread = await client.threads.create()
print(thread)
```
=== "Javascript"
```js
import { Client } from "@langchain/langgraph-sdk";
const client = new Client({ apiUrl:"whatever-your-deployment-url-is" });
// create thread
const thread = await client.threads.create();
console.log(thread)
```
Output:
{'thread_id': 'e1431c95-e241-4d1d-a252-27eceb1e5c86',
'created_at': '2024-06-21T15:48:59.808924+00:00',
'updated_at': '2024-06-21T15:48:59.808924+00:00',
'metadata': {}}
Let's also define a helper function for better formatting of the tool calls in messages
=== "Python"
```python
def format_tool_calls(tool_calls):
if tool_calls:
formatted_calls = []
for call in tool_calls:
formatted_calls.append(
f"Tool Call ID: {call['id']}, Function: {call['name']}, Arguments: {call['args']}"
)
return "\n".join(formatted_calls)
return "No tool calls"
```
=== "Javascript"
```js
function formatToolCalls(toolCalls) {
if (toolCalls && toolCalls.length > 0) {
const formattedCalls = toolCalls.map(call => {
return `Tool Call ID: ${call.id}, Function: ${call.name}, Arguments: ${call.args}`;
});
return formattedCalls.join("\n");
}
return "No tool calls";
}
```
Now we can stream by messages, which will return complete messages (at the end of node execution) as well as tokens for any messages generated inside a node:
=== "Python"
```python
input = {"messages": [{"role": "user", "content": "what's the weather in sf"}]}
config = {"configurable": {"model_name": "openai"}}
async for event in client.runs.stream(
thread["thread_id"],
assistant_id="agent",
input=input,
config=config,
stream_mode="messages",
):
if event.event == "metadata":
print(f"Metadata: Run ID - {event.data['run_id']}")
print("-" * 50)
elif event.event == "messages/partial":
for data_item in event.data:
if "role" in data_item and data_item["role"] == "user":
print(f"Human: {data_item['content']}")
else:
tool_calls = data_item.get("tool_calls", [])
invalid_tool_calls = data_item.get("invalid_tool_calls", [])
content = data_item.get("content", "")
response_metadata = data_item.get("response_metadata", {})
if content:
print(f"AI: {content}")
if tool_calls:
print("Tool Calls:")
print(format_tool_calls(tool_calls))
if invalid_tool_calls:
print("Invalid Tool Calls:")
print(format_tool_calls(invalid_tool_calls))

# How to configure multiple streaming modes at the same time
This guide covers how to configure multiple streaming modes at the same time.
First let's set up our client and thread:
=== "Python"
```python
from langgraph_sdk import get_client
client = get_client(url="whatever-your-deployment-url-is")
# create thread
thread = await client.threads.create()
print(thread)
```
=== "Javascript"
```js
import { Client } from "@langchain/langgraph-sdk";
const client = new Client({ apiUrl:"whatever-your-deployment-url-is" });
// create thread
const thread = await client.threads.create();
console.log(thread)
```
Output:
{'thread_id': 'bfc68029-1f7b-400f-beab-6f9032a52da4',
'created_at': '2024-06-24T21:30:07.980789+00:00',
'updated_at': '2024-06-24T21:30:07.980789+00:00',
'metadata': {}}
When configuring multiple streaming modes for a run, responses for each respective mode will be produced. In the following example, note that a `list` of modes (`messages`, `events`, `debug`) is passed to the `stream_mode` parameter and the response contains `events`, `debug`, `messages/complete`, `messages/metadata`, and `messages/partial` event types.
=== "Python"
```python
# create input
input = {
"messages": [
{
"role": "human",
"content": "What's the weather in SF?",
}
]
}
# stream events with multiple streaming modes
async for chunk in client.runs.stream(
thread_id=thread["thread_id"],
assistant_id="agent",
input=input,
stream_mode=["messages", "events", "debug"],
):
print(f"Receiving new event of type: {chunk.event}...")
print(chunk.data)
print("\n\n")
```
=== "Javascript"
```js
// create input
const input = {
"messages": [
{
"role": "human",
"content": "What's the weather in SF?",
}
]
}
// stream events with multiple streaming modes
const streamResponse = client.runs.stream(
thread["thread_id"],
"agent",
{
input,
streamMode: ["messages", "events", "debug"]
}
);
for await (const chunk of streamResponse) {
console.log(f"Receiving new event of type: {chunk.event}...")
console.log(chunk.data)
console.log("\n\n")
}
```

# How to stream state updates of your graph
LangGraph Cloud supports multiple streaming modes. The main ones are:
- `values`: This streaming mode streams back values of the graph. This is the **full state of the graph** after each node is called.
- `updates`: This streaming mode streams back updates to the graph. This is the **update to the state of the graph** after each node is called.
- `messages`: This streaming mode streams back messages - both complete messages (at the end of a node) as well as **tokens** for any messages generated inside a node. This mode is primarily meant for powering chat applications.
This guide covers `stream_mode="updates"`.
First let's set up our client and thread:
=== "Python"
```python
from langgraph_sdk import get_client
client = get_client(url="whatever-your-deployment-url-is")
# create thread
thread = await client.threads.create()
print(thread)
```
=== "Javascript"
```js
import { Client } from "@langchain/langgraph-sdk";
const client = new Client({ apiUrl:"whatever-your-deployment-url-is" });
// create thread
const thread = await client.threads.create();
console.log(thread)
```
Output:
{'thread_id': '979e3c89-a702-4882-87c2-7a59a250ce16',
'created_at': '2024-06-21T15:22:07.453100+00:00',
'updated_at': '2024-06-21T15:22:07.453100+00:00',
'metadata': {}}
Now we can stream by updates, which outputs updates made to the state by each node after it has executed:
=== "Python"
```python
input = {
"messages": [
{
"role": "human",
"content": "what's the weather in la"
}
]
}
async for chunk in client.runs.stream(
thread["thread_id"],
"agent",
input=input,
stream_mode="updates",
):
print(f"Receiving new event of type: {chunk.event}...")
print(chunk.data)
print("\n\n")
```
=== "Javascript"
```js
const input = {
"messages": [
{
"role": "human",
"content": "What's the weather in la",
}
]
}
const streamResponse = client.runs.stream(
thread["thread_id"],
"agent",
{
input,
streamMode: "updates"
}
);
for await (const chunk of streamResponse) {
console.log(f"Receiving new event of type: {chunk.event}...")
console.log(chunk.data)
console.log("\n\n")
}
```

# How to stream full state of your graph
LangGraph Cloud supports multiple streaming modes. The main ones are:
- `values`: This streaming mode streams back values of the graph. This is the **full state of the graph** after each node is called.
- `updates`: This streaming mode streams back updates to the graph. This is the **update to the state of the graph** after each node is called.
- `messages`: This streaming mode streams back messages - both complete messages (at the end of a node) as well as **tokens** for any messages generated inside a node. This mode is primarily meant for powering chat applications.
This guide covers `stream_mode="values"`.
First let's set up our client and thread:
=== "Python"
```python
from langgraph_sdk import get_client
client = get_client(url="whatever-your-deployment-url-is")
# create thread
thread = await client.threads.create()
print(thread)
```
=== "Javascript"
```js
import { Client } from "@langchain/langgraph-sdk";
const client = new Client({ apiUrl: "whatever-your-deployment-url-is" });
// create thread
const thread = await client.threads.create();
console.log(thread)
```
Output:
{'thread_id': 'bfc68029-1f7b-400f-beab-6f9032a52da4',
'created_at': '2024-06-24T21:30:07.980789+00:00',
'updated_at': '2024-06-24T21:30:07.980789+00:00',
'metadata': {}}
Now we can stream by values, which streams the full state of the graph after each node has finished executing:
=== "Python"
```python
input = {"messages": [{"role": "human", "content": "what's the weather in la"}]}
# stream values
async for chunk in client.runs.stream(
thread["thread_id"],
"agent",
input=input,
stream_mode="values"
):
print(f"Receiving new event of type: {chunk.event}...")
print(chunk.data)
print("\n\n")
```
=== "Javascript"
```js
const input = {"messages": [{"role": "human", "content": "what's the weather in la"}]}
const streamResponse = client.runs.stream(
thread["thread_id"],
"agent",
{
input,
streamMode: "values"
}
);
for await (const chunk of streamResponse) {
console.log(f"Receiving new event of type: {chunk.event}...")
console.log(chunk.data)
console.log("\n\n")
}
```
Output:

# Quick Start
This quick start guide will cover how to develop an application for LangGraph Cloud, run it locally in Docker, and call the APIs to invoke a graph.
Alternatively, clone or fork the [`langgraph/example`](https://github.com/langchain-ai/langgraph-example) GitHub repository and follow the instructions in the `README`.
This quick start guide will cover how to build a simple agent that can look up things on the internet. We will then deploy it to LangGraph Cloud, use the LangGraph Studio to visualize and test it out, and use the LangGraph SDK to interact with it.
## Set up requirements
This tutorial will use:
- Anthropic for the LLM - sign up and get an API key [here](https://console.anthropic.com/)
- Tavily for the search engine - sign up and get an API key [here](https://app.tavily.com/)
- LangSmith for hosting - sign up and get an API key [here](https://smith.langchain.com/)
## Set up local files

The following code is a simple example, the important thing is that at some point in your file you compile your graph and assign the compiled graph to a variable (in this case the `graph` variable).

4. The `langgraph.json` file is a configuration file that describes what graph you are going to host. It is important to note that you can host multiple graphs at a time. In this case we only host one: the `graph` Runnable from `agent.py`, but we could have defined multiple different graphs within `agent.py` to host, or written multiple python files to each host one or more graphs. Each graph you wish to host should have a unique identifier.
4. The [`langgraph.json`][langgraph.json] file is a configuration file that describes what graph(s) you are going to host. In this case we only have one graph to host: the compiled `graph` object from `agent.py`.
```json
{
"dependencies": ["."],
"graphs": {
"agent": "./agent.py:graph"
},
"env": ".env"
"dependencies": ["."],
"graphs": {
"agent": "./agent.py:graph"
},
"env": ".env"
}
```
Learn more about the LangGraph CLI configuration file [here](./reference/cli.md#configuration-file).
5. The `.env` file should contain the environment variables that are needed to run your graph. In this case we just need to specify the OpenAI API key, as well as the authentication type for langgraph.
5. The `.env` file should have any environment variables needed to run your graph. This will only be used for local testing, so if you are not testing locally you can skip this step. NOTE: if you do add this, you should NOT check this into git. For this graph, we need two environment variables:
OPENAI_API_KEY=<add your key here>
LANGGRAPH_AUTH_TYPE=noop
```shell
ANTHROPIC_API_KEY=...
TAVILY_API_KEY=...
```
!!! warning "Disable Authentication"
When testing locally, set `LANGGRAPH_AUTH_TYPE` to `noop` to disable authentication.
Now that we have set everything up on our local file system, we are ready to host our graph.
Now that we have set everything up on our local file system, we are ready to host our graph.
## Test the graph build locally
## Run Locally
Before deploying to the cloud, we probably want to test the building of our graph locally. This is useful to make sure we have configured our [CLI configuration file][langgraph.json] correctly and our graph runs.
1. Install the [LangGraph CLI](./reference/cli.md#installation).
In order to do this we can first install the LangGraph CLI
2. Run the following command to start the API server in Docker:
```shell
pip install langgraph-cli
```
langgraph up -c langgraph.json
We can then test our API server locally. This requires access to LangGraph closed beta. In order to run the server locally, you will need to add your `LANGSMITH_API_KEY` to the .env file so we can validate you have access to LangGraph closed beta.
3. The API server is now running at `http://localhost:8123`. Navigate to [`http://localhost:8123/docs`](http://localhost:8123/docs) to view the API docs.
```shell
langgraph up
```
4. You can now test that your deployment is working as intended by invoking some of the cURL commands from the API docs.
This will start up the LangGraph API server locally. If this runs successfully, you should see something like:
First, let's test that the assistant we are hosting is indeed retrievable by the API, which we can do by using the "assistants/search" endpoint:
```shell
Ready!
- API: http://localhost:8123
2024-06-26 19:20:41,056:INFO:uvicorn.access 127.0.0.1:44138 - "GET /ok HTTP/1.1" 200
```
curl --request POST \
--url http://localhost:8123/assistants/search \
--header 'Content-Type: application/json' \
--data '{
"metadata": {},
"limit": 10,
"offset": 0
}
You can now test this out! **Note: this local server is intended SOLELY for local testing purposes and is not performant enough for production applications, so please do not use it as such.** To test it out, you can go to another terminal window and run:
If the hosting is working as expected, you should receive a 200 response which looks something like this example response:
[
{
"assistant_id": "123e4567-e89b-12d3-a456-426614174000",
"graph_id": "agent",
"config": {
"tags": [
"…"
],
"recursion_limit": 1,
"configurable": {}
},
"created_at": "2024-06-24T19:21:47.514Z",
"updated_at": "2024-06-24T19:21:47.514Z",
"metadata": {}
}
]
If you are hosting multiple graphs, you should see all of them in this response. Once you have verified that this step is working as intended, you can test out that invoking your hosted graphs works as intended without any bugs. You can do this by calling the a version of the following cURL command:
curl --request POST \
--url http://localhost:8123/runs/stream \
--header 'Content-Type: application/json' \
--data '{
"assistant_id": "123e4567-e89b-12d3-a456-426614174000",
"input": {
"messages": [
{
```shell
curl --request POST \
--url http://localhost:8123/runs/stream \
--header 'Content-Type: application/json' \
--data '{
"assistant_id": "agent",
"input": {
"messages": [
{
"role": "user",
"content": "How are you?"
}
]
},
"metadata": {},
"config": {
"configurable": {}
},
"multitask_strategy": "reject",
"stream_mode": [
"values"
}
]
}'
},
"metadata": {},
"config": {
"configurable": {}
},
"multitask_strategy": "reject",
"stream_mode": [
"values"
]
}'
```
Make sure to edit the `input` and `assistant_id` fields to match what assistant you want to test. If you receive a 200 response then congratulations your graph has run successfully and you are ready to move on to hosting on Langgraph Cloud!
If you get back a valid response, then all is functioning properly!
## Deploy to Cloud
### Push your code to GitHub
Create a git repo in the `<my-app>` directory, and verify its existence. You can use the GitHub CLI if you like, or just create a repo manually.
Turn the `<my-app>` directory into a GitHub repo. You can use the GitHub CLI if you like, or just create a repo manually (if unfamiliar, instructions [here](https://docs.github.com/en/migrations/importing-source-code/using-the-command-line-to-import-source-code/adding-locally-hosted-code-to-github)).
### Deploy from GitHub with LangGraph Cloud
Once you have created your github repository with a Python file containing your compiled graph as well as a `langgraph.json` file containing the configuration for hosting your graph, you can head over to LangSmith and click on the 🚀 icon on the left navbar to create a new deployment. Click the `+ New Deployment` button.

5. For Git Reference, you can select either the git branch for the code you want to deploy, or the exact commit SHA.
6. If your chain relies on environment variables (for example, an OPENAI_API_KEY), add those in. They will be propagated to the underlying server so your code can access them.

## Use with the SDK
Once you have tested that your hosted graph works as expected using Langgraph Studio, you can start using your hosted graph all over your organization by using the Langgraph SDK. You can learn about how to do that by following [this how-to guide](./sdk/python_sdk.ipynb)
Once you have tested that your hosted graph works as expected using LangGraph Studio, you can start using your hosted graph all over your organization by using the LangGraph SDK. Let's see how we can access our hosted graph and execute our run from a python file.
First, make sure you have the SDK installed by calling `pip install langgraph_sdk`.
Before using, you need to get the URL of your LangGraph deployment. You can find this in the `Deployment` view. Click the URL to copy it to the clipboard.
You also need to make sure you have set up your API key properly so you can authenticate with LangGraph Cloud.
```shell
export LANGSMITH_API_KEY=...
```
The first thing to do when using the SDK is to setup our client, access our assistant, and create a thread to execute a run on:
```python
from langgraph_sdk import get_client
# Replace this with the URL of your own deployed graph
URL = "https://chatbot-23a570f3210f52a7b167f09f6158e3b3-ffoprvkqsa-uc.a.run.app"
client = get_client(url=URL)
# Search all hosted graphs
assistants = await client.assistants.search()
# In this example we select the first assistant since we are only hosting a single graph
assistant = assistants[0]
# We create a thread for tracking the state of our run
thread = await client.threads.create()
```
We can then execute a run on the thread:
```python
input = {"messages":[{"role": "user", "content": "Hello! My name is Bagatur and I am 26 years old."}]}
async for chunk in client.runs.stream(
thread['thread_id'],
assistant["assistant_id"],
input=input,
stream_mode="updates",
):
if chunk.data and chunk.event != "metadata":
print(chunk.data)
```
{'agent': {'messages': [{'content': "Hi Bagatur! It's nice to meet you. How can I assist you today?", 'additional_kwargs': {}, 'response_metadata': {'finish_reason': 'stop', 'model_name': 'gpt-4o-2024-05-13', 'system_fingerprint': 'fp_9cb5d38cf7'}, 'type': 'ai', 'name': None, 'id': 'run-c89118b7-1b1e-42b9-a85d-c43fe99881cd', 'example': False, 'tool_calls': [], 'invalid_tool_calls': [], 'usage_metadata': None}]}}

Memory is a key concept to agentic applications. Memory is important because end users often expect the application they are interacting with remember previous interactions. The most simple example of this is chatbots - they clearly need to remember previous messages in a conversation.
LangGraph is perfectly suited to give you full control over the memory of your application. With user defined [`State`](#state) you can specify the exact schema of the memory you want to retain. With [checkpointers](#checkpointer) you can store checkpoints of previous interactions and resume from there in follow up interactions.

See [this guide](../how-tos/persistence.ipynb) for how to add memory to your graph.
## Human-in-the-loop
Agentic systems often require some human-in-the-loop (or "on-the-loop") interaction patterns. This is because agentic systems are still not super reliable, so having a human involved is required for any sensitive tasks/actions. These are all easily enabled in LangGraph, largely due to [checkpointers](#checkpointer). The reason a checkpointer is necessary is that a lot of these interaction patterns involve running a graph up until a certain point, waiting for some sort of human feedback, and then continuing. When you want to "continue" you will need to access the state of the graph previous to getting interrupted, and checkpointers are a built in, highly convenient way to do that.

There are a few common human-in-the-loop interaction patterns we see emerging.
### Approval
A basic one is to have the agent wait for approval before executing certain tools. This may be all tools, or just a subset of tools. This is generally recommend for more sensitive actions (like writing to a database). This can easily be done in LangGraph by setting a [breakpoint](#breakpoints) before specific nodes.

### Time travel
This is a pretty advanced interaction pattern. In this interaction pattern, the human can look back at the list of previous checkpoints, find one they like, optionally [edit it](#edit-agent-actions), and then resume execution from there.
See [this guide](../how-tos/human_in_the_loop/time-travel.ipynb) for how to do this in LangGraph.
## Map-Reduce
A common pattern in agents is to generate a list of objects, do some work on each of those objects, and then combine the results. This is very similar to the common [map-reduce](https://en.wikipedia.org/wiki/MapReduce) operation. This can be tricky for a few reasons. First, it can be tough to define a structured graph ahead of time because the length of the list of objects may be unknown. Second, in order to do this map-reduce you need multiple versions of the state to exist... but the graph shares a common shared state, so how can this be?
LangGraph supports this via the [Send](#send) api. This can be used to allow a conditional edge to Send multiple different states to multiple nodes. The state it sends can be different from the state of the core graph.

# FAQ
Common questions and their answers!
## Do I need to use LangChain in order to use LangGraph?
No! LangGraph is a general-purpose framework - the nodes and edges are nothing more than Python functions. You can use LangChain, raw HTTP requests, or even other frameworks inside these nodes and edges.
## Does LangGraph work with LLMs that don't support tool calling?
Yes! You can use LangGraph with any LLMs. The main reason we use LLMs that support tool calling is that this is often the most convenient way to have the LLM make its decision about what to do. If your LLM does not support tool calling, you can still use it - you just need to write a bit of logic to convert the raw LLM string response to a decision about what to do.
## Does LangGraph work with OSS LLMs?
Yes! LangGraph is totally ambivalent to what LLMs are used under the hood. The main reason we use closed LLMs in most of the tutorials is that they seamlessly support tool calling, while OSS LLMs often don't. But tool calling is not necessary (see [this section](#does-langgraph-work-with-llms-that-dont-support-tool-calling)) so you can totally use LangGraph with OSS LLMs.

At its core, LangGraph models agent workflows as graphs. You define the behavior of your agents using three key components:
1. `State`: A shared data structure that represents the current snapshot of your application. It can be any Python type, but is typically a `TypedDict` or Pydantic `BaseModel`.
1. [`State`](#state): A shared data structure that represents the current snapshot of your application. It can be any Python type, but is typically a `TypedDict` or Pydantic `BaseModel`.
2. `Nodes`: Python functions that encode the logic of your agents. They receive the current `State` as input, perform some computation or side-effect, and return an updated `State`.
2. [`Nodes`](#nodes): Python functions that encode the logic of your agents. They receive the current `State` as input, perform some computation or side-effect, and return an updated `State`.
3. `Edges`: Python functions that determine which `Node` to execute next based on the current `State`. They can be conditional branches or fixed transitions.
3. [`Edges`](#edges): Python functions that determine which `Node` to execute next based on the current `State`. They can be conditional branches or fixed transitions.
By composing `Nodes` and `Edges`, you can create complex, looping workflows that evolve the `State` over time. The real power, though, comes from how LangGraph manages that `State`. To emphasize: `Nodes` and `Edges` are nothing more than Python functions - they can contain an LLM or just good ol' Python code.
In short: _nodes do the work. edges tell what to do next_.
LangGraph's underlying graph algorithm uses [message passing](https://en.wikipedia.org/wiki/Message_passing) to define a general program. When a `Node` completes, it sends a message along one or more edges to other node(s). These nodes run their functions, pass the resulting messages to the next set of nodes, and on and on it goes. Inspired by [Pregel](https://research.google/pubs/pregel-a-system-for-large-scale-graph-processing/), the program proceeds in discrete "super-steps" that are all executed conceptually in parallel. Whenever the graph is run, all the nodes start in an `inactive` state. Whenever an incoming edge (or "channel") receives a new message (state), the node becomes `active`, runs the function, and responds with updates. At the end of each superstep, each node votes to `halt` by marking itself as `inactive` if it has no more incoming messages. The graph terminates when all nodes are `inactive` and when no messages are in transit.

A super-step can be considered a single iteration over the graph nodes. Nodes that run in parallel are part of the same super-step, while nodes that run sequentially belong to separate super-steps. At the start of graph execution, all nodes begin in an `inactive` state. A node becomes `active` when it receives a new message (state) on any of its incoming edges (or "channels"). The active node then runs its function and responds with updates. At the end of each super-step, nodes with no incoming messages vote to `halt` by marking themselves as `inactive`.

## `Send`
By default, `Nodes` and `Edges` are defined ahead of time and operate on the same shared state. However, there can be cases where the exact edges are not known ahead of time and/or you may want different versions of `State` to exist at the same time. A common of example of this is with `map-reduce` design patterns. In this design pattern, a first node may generate a list of objects, and you may want to apply some other node to all those objects. The number of objects may be unknown ahead of time (meaning the number of edges may not be known) and the input `State` to the downstream `Node` should be different (one for each generated object).
To support this design pattern, LangGraph supports returning [`Send`](https://langchain-ai.github.io/langgraph/reference/graphs/#send) objects from conditional edges. `Send` takes two arguments: first is the name of the node, and second is the state to pass to that node.

## Checkpointer
One of the main benefits of LangGraph is that it comes backed by a persistence layer. This is accomplished via [checkpointers](https://langchain-ai.github.io/langgraph/reference/checkpoints/#basecheckpointsaver).
LangGraph has a built-in persistence layer, implemented through [checkpointers][basecheckpointsaver]. When you use a checkpointer with a graph, you can interact with the state of that graph. When you use a checkpointer with a graph, you can interact with and manage the graph's state. The checkpointer saves a _checkpoint_ of the graph state at every super-step, enabling several powerful capabilities:
Checkpointers can be used to save a _checkpoint_ of the state of a graph after all steps of the graph. This allows for several things.
First, checkpointers facilitate [human-in-the-loop workflows](agentic_concepts.md#human-in-the-loop) workflows by allowing humans to inspect, interrupt, and approve steps.Checkpointers are needed for these workflows as the human has to be able to view the state of a graph at any point in time, and the graph has to be to resume execution after the human has made any updates to the state.

Checkpointers are needed for these workflows as the human has to be able to view the state of a graph at any point in time, and the graph has to be to resume execution after the human has made any updates to the state.
Second, it allows for ["memory"](agentic_concepts.md#memory) between interactions. You can use checkpointers to create threads and save the state of a thread after a graph executes. In the case of repeated human interactions (like conversations) any follow up messages can be sent to that checkpoint, which will retain its memory of previous ones.

Threads are used to checkpoint multiple different runs. This can be used to enable a multi-tenant chat applications.
Threads enable the checkpointing of multiple different runs, making them essential for multi-tenant chat applications and other scenarios where maintaining separate states is necessary. A thread is a unique ID assigned to a series of checkpoints saved by a checkpointer. When using a checkpointer, you must specify a `thread_id` or `thread_ts` when running the graph.
`thread_id` is simply the ID of a thread. This is always required

## Checkpointer state
When you use a checkpointer with a graph, you can interact with the state of that graph.
This usually done when enabling different human-in-the-loop interaction patterns.
When interacting with the checkpointer state, you must specify [thread identifiers](#threads)
When interacting with the checkpointer state, you must specify a [thread identifier](#threads).Each checkpoint saved by the checkpointer has two properties:
Each checkpoint has two properties:

## Breakpoints
It can often be useful to set breakpoints before or after certain nodes execute. This can be used to wait for human approval before continuing. These can be set when you ["compile" a graph](#compiling-your-graph). You can set breakpoints either *before* a node executes (using `interrupt_before`) or after a node executes (using `interrupt_after`.)

## Visualization
It's often nice to be able to visualize graphs, especially as they get more complex. LangGraph comes with several built-in ways to visualize graphs. See [this how-to guide](https://langchain-ai.github.io/langgraph/how-tos/visualization/) for more info.

## Streaming
LangGraph is built with first class support for streaming. There are several different streaming modes that LangGraph supports:
- `"values"`: This streams the full value of the state after each step of the graph.
- `"updates`: This streams the updates to the state after each step of the graph. If multiple updates are made in the same step (e.g. multiple nodes are run) then those updates are streamed separately.
- [`"values"`](../how-tos/stream-values.ipynb): This streams the full value of the state after each step of the graph.
- [`"updates`](../how-tos/stream-updates.ipynb): This streams the updates to the state after each step of the graph. If multiple updates are made in the same step (e.g. multiple nodes are run) then those updates are streamed separately.
- `"debug"`: This streams as much information as possible throughout the execution of the graph.
In addition, you can use the [`astream_events`](https://langchain-ai.github.io/langgraph/how-tos/streaming-tokens/) method to stream back events that happen _inside_ nodes. This is useful for streaming tokens of LLM calls.
In addition, you can use the [`astream_events`](../how-tos/streaming-events-from-within-tools.ipynb) method to stream back events that happen _inside_ nodes. This is useful for [streaming tokens of LLM calls](../how-tos/streaming-tokens.ipynb).

"# How to Wait for User Input\n",
"\n",
"One of the main human-in-the-loop interaction patterns is waiting for human input. A key use case involves asking the user clarifying questions. One way to accomplish this is simply go to the END node and exit the graph. Then, any user response comes back in as fresh invocation of the graph. This is basically just creating a chatbot architecture.\n",
"\n",
"The issue with this is it is tough to resume back in a particular point in the graph. Often times the agent is halfway through some process, and just needs a bit of a user input. Although it is possible to design your graph in such a way where you have a `conditional_entry_point` to route user messages back to the right place, that is not super scalable (as it essentially involves having a routing function that can end up almost anywhere).\n",
"\n",
"A separate way to do this is to have a node explicitly for getting user input. This is easy to implement in a notebook setting - you just put an `input()` call in the node. But that isn't exactly production ready.\n",
"\n",
"Luckily, LangGraph makes it possible to do similar things in a production way. The basic idea is:\n",
"\n",
"- Set up a node that represents human input. This can have specific incoming/outgoing edges (as you desire). There shouldn't actually be any logic inside this node.\n",
"- Add a breakpoint before the node. This will stop the graph before this node executes (which is good, because there's no real logic in it anyways)\n",
"- Use `.update_state` to update the state of the graph. Pass in whatever human response you get. The key here is to use the `as_node` parameter to apply this update **as if you were that node**. This will have the effect of making it so that when you resume execution next it resumes as if that node just acted, and not from the beginning."

"\n",
"- Mild temperatures with highs in the 60s F and lows in the 50s F\n",
"- Foggy mornings that often burn off to sunny afternoons\n",
"- Little to no rainfall, as June falls in the dry season\n",

"# How to stream messages from your graph\n",
"\n",
"LangGraph Cloud supports multiple streaming modes. The main ones are:\n",
"\n",
"- `values`: This streaming mode streams back values of the graph. This is the **full state of the graph** after each node is called.\n",
"- `updates`: This streaming mode streams back updates to the graph. This is the **update to the state of the graph** after each node is called.\n",
"- `messages`: This streaming mode streams back messages - both complete messages (at the end of a node) as well as **tokens** for any messages generated inside a node. This mode is primarily meant for powering chat applications.\n",
"\n",
"\n",
"This guide covers `stream_mode=\"messages\"`.\n",
"\n",
"In order to use this mode, the state of the graph you are interacting with MUST have a messages key that is a list of messages.\n",
"Eg, the state should look something like:\n",
"\n",
"```python\n",
"from typing import TypedDict, Annotated\n",
"from langgraph.graph import add_messages\n",
"from langchain_core.messages import AnyMessage\n",
"\n",
"class State(TypedDict):\n",
" messages: Annotated[list[AnyMessage], add_messages]\n",
"```\n",
"\n",
"OR it should be an instance or subclass of `from langgraph.graph import MessageState` (`MessageState` is just a helper type hint equivalent to the above).\n",
"\n",
"With `stream_mode=\"messages\"` two things will be streamed back:\n",
"\n",
"- It outputs messages produced by any chat model called inside (unless tagged in a special way)\n",
"- It outputs messages returned from nodes (to allow for nodes to return `ToolMessages` and the like"
