Code without a preview is just text. You'll spin up a local dev server, open localhost:3000 in your browser, and see your prototype rendered in real-time — refreshing automatically every time Claude Code makes a change.

See Your Prototype Live

Exit Claude Code

Type exit and press Enter to return to Terminal.

Initialize a React App (If Needed)

Run:

Terminal
npx create-react-app .

This sets up the structure React needs to run.

Start Your Development Server

Run:

Terminal
npm start

Your prototype will automatically open in your browser at localhost:3000!

Watch for Live Updates

When Claude Code makes changes, your browser automatically updates. No manual refresh needed!

Live preview running

  • Set up the React project structure with create-react-app
  • Started the dev server with npm start
  • Confirmed the prototype renders at localhost:3000 with live reload

Two windows, one workflow. Last lesson in this module: keeping the dev server running while you keep editing.
