Learn AI Agent

A small monorepo for learning how AI agents are built.

The learning roadmap will be added later. This repo currently contains the base Node.js workspace, tooling, and a simple Hono API app to make sure the setup can run, typecheck, and test cleanly. The AI agent learning path will focus on Node.js, LangChain, and LangGraph.

Stack

Commands

nvm use
pnpm install
pnpm dev
pnpm check
pnpm test:e2e

This repo enforces the Node.js and pnpm versions declared in package.json. If you switch from another repo and run a pnpm command with the wrong runtime, pnpm will stop with an engine error instead of continuing with a mismatched version.
