About the Book

Unlock the power of Cyclical AI with LangGraph.js.

The era of linear "chains" is ending. The future of AI engineering belongs to Agents—systems that can reason, loop, self-correct, and collaborate. Building Autonomous Agents with LangGraph.js is your deep-dive technical guide to mastering the framework that is redefining how we build LLM applications.

Written for serious TypeScript developers and AI engineers, this book skips the fluff and goes straight into the architecture of stateful, multi-agent systems. You won't just learn syntax; you will learn the design patterns used in production-grade SaaS applications.

Inside Volume 1, you will discover:

  • The Agentic Shift: Why loops and state persistence are the keys to autonomous problem solving.
  • Core Architectures: Master the ReAct pattern, Plan-and-Execute workflows, and Reflection loops that allow agents to fix their own mistakes.
  • Multi-Agent Orchestration: Build hierarchical teams where Supervisor Agents delegate tasks to specialized workers (Coders, Researchers, Reviewers).
  • Advanced State Management: Implement Postgres Checkpointing for long-running processes and master Time Travel debugging to rewind and fork agent execution.
  • Human-in-the-Loop: Design safe systems that pause for human approval before executing sensitive actions.
  • Production Deployment: Learn how to stream events to a frontend, implement Optimistic UIs, and deploy using Docker and LangGraph Cloud.

Whether you are building a coding assistant, a customer support bot, or a complex research engine, this book provides the blueprints you need to build reliable, scalable, and intelligent systems.

Stop building scripts. Start building Agents.

About the Author

Edgar Milvus

A veteran software engineer with 20 years of experience, I have dedicated my career to the art of automation. My philosophy is simple: programming should eliminate repetitive chores to unlock human creativity. This journey began early on with the development of custom code-generation tools and has evolved into a deep mastery of LLMs and their APIs. Today, I specialize in architecting AI-driven solutions that handle everything from complex coding and security tasks to advanced knowledge retrieval, transforming the way we interact with technology
