Building High-Performance Vector Search in Node.js with FAISS — Without Blocking the Event Loop

If you're building a RAG pipeline, semantic search engine, or AI-powered app in Node.js, you've probably hit the same wall I did - vector search libraries that freeze your entire server while searching through embeddings. Today I want to share faiss-node-native, a project I've been building to fix exactly that. What is Vector Search and Why Does It Matter? Modern AI applications - chatbots, semantic search, recommendation engines - all rely on embeddings: high-dimensional vectors that represent the meaning of text, images, or audio.
