In this book, we take you on a fun, hands-on and pragmatic journey to learning LangGraph. You'll start building your first graph within minutes. Every chapter is written in a bite-sized manner and straight to the point as I don’t want to waste your time (and most certainly mine) on the content you don't need.

In the course of this book, we will cover:
