Build a ReAct Agent with LangGraph

In this video, I’ll walk you through building a ReAct agent using LangGraph from scratch.
We’ll cover everything step by step — from understanding graph architecture, nodes, edges, states, and tools — to implementing an agent that can query Wikipedia.

I’ll first build the agent using LangGraph’s basic building blocks and test it. Then, I’ll also show you how to create the same agent using LangGraph’s prebuilt create_react_agent for faster development.

To make it more practical, I’ll showcase how you can trace and debug the workflow in LangSmith, giving you clear insights into how your agent is reasoning and acting.

If you’re learning LangChain, LangGraph, or AI agents, this tutorial will help you build a strong foundation.
