Clone the repository with git clone, run npm install to install dependencies, copy .env.example to .env and fill in MongoDB URI and JWT secret, then run npm run dev to start the Express server.
Either works. Local MongoDB is faster and doesn't require internet. MongoDB Atlas is easier to set up (no local install) and is free for small projects. Use Atlas if you want a managed cloud database.
After starting the server, use curl or Postman to hit POST /api/signup with a JSON body containing firstName, lastName, email, and password. A 201 response with user data and a Set-Cookie header confirms it works.
