-# LangGraph JS/TS SDK
-
-This repository contains the JS/TS SDK for interacting with the LangGraph REST API.
-
-## Quick Start
-
-To get started with the JS/TS SDK, [install the package](https://www.npmjs.com/package/@langchain/langgraph-sdk)
-
-```bash
-yarn add @langchain/langgraph-sdk
-```
-
-You will need a running LangGraph API server. If you're running a server locally using `langgraph-cli`, SDK will automatically point at `http://localhost:8123`, otherwise
-you would need to specify the server URL when creating a client.
-
-```js
-import { Client } from "@langchain/langgraph-sdk";
-
-const client = new Client();
-
-// List all assistants
-const assistants = await client.assistants.search({
- metadata: null,
- offset: 0,
- limit: 10,
-});
-
-// We auto-create an assistant for each graph you register in config.
-const agent = assistants[0];
-
-// Start a new thread
-const thread = await client.threads.create();
-
-// Start a streaming run
-const messages = [{ role: "human", content: "what's the weather in la" }];
-
-const streamResponse = client.runs.stream(
- thread["thread_id"],
- agent["assistant_id"],
- {
- input: { messages },
- }
-);
-
-for await (const chunk of streamResponse) {
- console.log(chunk);
-}
-```
-
-## Documentation
-
-To generate documentation, run the following commands:
-
-1. Generate docs.
-
- yarn typedoc
-
-1. Consolidate doc files into one markdown file.
-
- npx concat-md --decrease-title-levels --ignore=js_ts_sdk_ref.md --start-title-level-at 2 docs > docs/js_ts_sdk_ref.md
-
-1. Copy `js_ts_sdk_ref.md` to MkDocs directory.
-
- cp docs/js_ts_sdk_ref.md ../../docs/docs/cloud/reference/sdk/js_ts_sdk_ref.md
