@obyflow/adapter-framework

LangChain callback handler adapter for Obyflow, turning LangChain chain/tool/LLM run callbacks into Obyflow chain, tool_call, and llm_call events.

This package is consumed internally by @obyflow/node's instrument.langchain() helper. Install it directly only if you're wiring LangChain instrumentation into a custom setup outside the Node SDK.

Install

npm install @obyflow/adapter-framework

Requires Node.js ≥ 22. Has no dependency on langchain itself — it works structurally against any compatible callback-handler version.

Usage

import { createLangChainCallbackHandler } from "@obyflow/adapter-framework";

const handler = createLangChainCallbackHandler({
  service: "checkout-api",
  emit: (event) => store.append(event),
});
