LangGraph

Adds instrumentation for LangGraph.

Import name: Sentry.langChainIntegration

LangGraph is instrumented via the langChainIntegration, which automatically captures spans for LangGraph operations including agent invocations, graph executions, and node operations.

Copied
import { ChatOpenAI } from "@langchain/openai";
import { createReactAgent } from "@langchain/langgraph/prebuilt";
import { HumanMessage, SystemMessage } from "@langchain/core/messages";

// Create LLM and agent
const llm = new ChatOpenAI({
  modelName: "gpt-4o",
  apiKey: process.env.OPENAI_API_KEY,
});

const agent = createReactAgent({ llm, tools: [] });

// Invoke the agent - automatically instrumented
const result = await agent.invoke({
  messages: [
    new SystemMessage("You are a helpful assistant."),
    new HumanMessage("Hello!"),
  ],
});

For configuration options, runtime-specific setup, and detailed information, see the LangChain integration documentation.
