# Reference
|
|
|
|
Welcome to the LangGraph reference docs! These pages detail the core interfaces you will use when building with LangGraph. Each section covers a different part of the ecosystem.
|
|
|
|
!!! tip
|
|
|
|
If you are just getting started, see [LangGraph basics](../concepts/why-langgraph.md) for an introduction to the main concepts and usage patterns.
|
|
|
|
|
|
## LangGraph
|
|
|
|
The core APIs for the LangGraph open source library.
|
|
|
|
- [Graphs](graphs.md): Main graph abstraction and usage.
|
|
- [Functional API](func.md): Functional programming interface for graphs.
|
|
- [Pregel](pregel.md): Pregel-inspired computation model.
|
|
- [Checkpointing](checkpoints.md): Saving and restoring graph state.
|
|
- [Storage](store.md): Storage backends and options.
|
|
- [Caching](cache.md): Caching mechanisms for performance.
|
|
- [Types](types.md): Type definitions for graph components.
|
|
- [Config](config.md): Configuration options.
|
|
- [Errors](errors.md): Error types and handling.
|
|
- [Constants](constants.md): Global constants.
|
|
- [Channels](channels.md): Message passing and channels.
|
|
|
|
## Prebuilt components
|
|
|
|
Higher-level abstractions for common workflows, agents, and other patterns.
|
|
|
|
- [Agents](agents.md): Built-in agent patterns.
|
|
- [Supervisor](supervisor.md): Orchestration and delegation.
|
|
- [Swarm](swarm.md): Multi-agent collaboration.
|
|
- [MCP Adapters](mcp.md): Integrations with external systems.
|
|
|
|
## LangGraph Platform
|
|
|
|
Tools for deploying and connecting to the LangGraph Platform.
|
|
|
|
- [CLI](../cloud/reference/cli.md): Command-line interface for building and deploying LangGraph Platform applications.
|
|
- [Server API](../cloud/reference/api/api_ref.md): REST API for the LangGraph Server.
|
|
- [SDK (Python)](../cloud/reference/sdk/python_sdk_ref.md): Python SDK for interacting with instances of the LangGraph Server.
|
|
- [SDK (JS/TS)](../cloud/reference/sdk/js_ts_sdk_ref.md): JavaScript/TypeScript SDK for interacting with instances of the LangGraph Server.
|
|
- [RemoteGraph](remote_graph.md): `Pregel` abstraction for connecting to LangGraph Server instances.
|
|
- [Environment variables](../cloud/reference/env_var.md): Supported configuration variables when deploying with the LangGraph Platform. |
