Install LangGraph

To install the base LangGraph package:

npm install @langchain/langgraph @langchain/core

pnpm add @langchain/langgraph @langchain/core

yarn add @langchain/langgraph @langchain/core

bun add @langchain/langgraph @langchain/core

To use LangGraph you will usually want to access LLMs and define tools. You can do this however you see fit.

One way to do this (which we will use in the docs) is to use LangChain.

Install LangChain with:

npm install langchain

pnpm add langchain

yarn add langchain

bun add langchain

To work with specific LLM provider packages, you will need install them separately.

Refer to the integrations page for provider-specific installation instructions.
