A JavaScript/Node.js tutorial project that builds a RAG (retrieval-augmented generation) pipeline from scratch using node-llama-cpp with local LLMs. It walks through embeddings, vector search, retrieval, and context-augmented generation without hiding the internals behind a framework.

You want to actually understand how RAG works rather than treating it as a black box.

Use it to

  • Learn how RAG pipelines work step by step
  • Run a local LLM chatbot with retrieval
  • Study embeddings and vector search in Node.js
  • Use as a starting point for a custom RAG chatbot

For Node.js developers learning RAG concepts hands-on
