Udemy – AI Engineering with LangChain for JavaScript Developers

In this course, you’ll start from a blank TypeScript project and end with a working AI Engineering Copilot — an agent system that takes a feature request, searches the web, reads your codebase, writes multi-file code changes, gets your approval, and opens a GitHub pull request. Fully automated. Fully understandable. Every concept is introduced with a minimal standalone example before it’s wired into the Copilot, so you always know what you’re building and why.

What makes this course different:

• Everything is in TypeScript — no Python detour required
• You build one real system across the entire course, adding one capability per section
• You learn LangChain and LangGraph by using them for something that actually matters
• The Copilot you build is a realistic, production-inspired system — not a toy demo
