Building a RAG System from Scratch with Next.js: Vectors, Chunking, and Real-World Retrieval
Learn how to build a production-grade Retrieval-Augmented Generation (RAG) system using Next.js App Router and TypeScript. This deep dive covers embedding models, chunking strategies, pgvector and Pinecone setup, semantic search, hybrid retrieval, and streaming LLM responses — everything you need to ship a real-world RAG app.
