aiwithts/langgraph-js-mastery

This is a hands-on coding sandbox for the LangGraph.js Mastery course, where developers build progressively complex AI agents using TypeScript across 36 structured lessons. The project provides a pre-configured Next.js chat interface and PostgreSQL database, with each lesson containing a `graph.ts` file that learners fill in to create AI systems that think, remember, and act. It's designed for developers wanting to master LangGraph.js through practical implementation, covering fundamentals through production-ready AI systems with built-in testing and validation.
