LangChain.js is a TypeScript/JavaScript framework for building applications powered by large language models (LLMs). It provides modular, interoperable components—like models, tools, and data connectors—to simplify the development of context-aware reasoning and agent-based workflows. The project is designed for JavaScript and TypeScript developers across environments like Node.js, browsers, and edge platforms who need to create, experiment with, and deploy AI applications efficiently.
