GraphRAG.js
The comprehensive Graph RAG framework for JavaScript and TypeScript.
Overview
GraphRAG.js is the most complete Graph RAG implementation for the JavaScript ecosystem. It unifies all major graph-enhanced retrieval algorithms—LightRAG, Microsoft GraphRAG, Fast GraphRAG, and AWS GraphRAG—into a single, production-ready framework with a consistent API.
With 1,000+ GitHub stars and 20,000+ npm downloads, GraphRAG.js has become the go-to solution for teams building intelligent retrieval systems in Node.js and TypeScript environments.
Why GraphRAG.js
Traditional vector search retrieves similar text chunks. Graph-enhanced RAG goes further—understanding relationships between entities, leveraging community structures, and following multi-hop reasoning paths. This results in more accurate, contextually rich answers for complex queries.
GraphRAG.js eliminates the need to choose between competing algorithms or maintain multiple implementations. One framework, all strategies, production-ready.
