About the book

I wrote this book for working JavaScript developers who keep hearing about vector search and want to build with it, not just read definitions of it. It walks through what embeddings are, how similarity search works, and then spends most of its pages building a real search service in Node.js.

You don't need a math background. By the end you will have generated embeddings, built and tuned a vector index, and shipped search that understands meaning instead of matching keywords.

In the book

  • Generate embeddings and construct efficient vector indexes
  • Build recommendation systems and personalized search
  • Power content discovery with semantic search
  • Integrate vector search into JavaScript applications
  • Build scalable, high-performance search systems
