Stop writing chatbots. Start engineering intelligent systems.

This is the definitive guide for Node.js developers ready to build production-grade AI agents that reason, act, and evolve.

Building AI Agents with TypeScript moves beyond simple API calls to teach you the architecture of modern agentic workflows. You will learn to construct robust "ReAct" loops, orchestrate multi-agent swarms, and deploy self-correcting systems using the latest 2026 stack: LangChain.js, LangGraph, and Node.js 24. From handling the newest models like GPT-5 and Claude 3.7 to mastering RAG 2.0 with vector databases, this book bridges the gap between experimental prototypes and scalable, high-value enterprise applications.

What You Will Learn:

  • Agentic Architecture: Master the shift from brittle "chains" to adaptive "loops" that can reason and recover from errors.

  • The 2026 Tech Stack: Build with strict-mode TypeScript, Node.js 24, and pnpm for type-safe, production-ready code.

  • Advanced RAG 2.0: Implement hybrid search, re-ranking, and GraphRAG to ground your agents in reality.

  • Multi-Agent Swarms: Create "supervisor" architectures where specialized agents collaborate to solve complex tasks.

  • Production Mastery: Learn to deploy, scale, and monetize your agents in the emerging Agent Economy.
