Llm Application Dev

You get practical patterns for prompt engineering (structured prompts, few-shot examples, chain of thought), complete code samples for integrating OpenAI and Anthropic APIs, and a working RAG implementation with document chunking and vector search using pgvector. The error handling section covers retry logic and rate limiting, which you'll definitely need in production. It's TypeScript-focused and assumes you're familiar with async patterns. Best used when you're past the experimentation phase and need production-ready patterns for chatbots, semantic search, or AI-enhanced features.
