Course introduction

This course is for Product Managers and founders who want to turn a static web app into a real product. With an AI coding agent, you add user accounts, a protected database and a Stripe payment in test mode, then check every piece yourself. You leave with your upgraded app and a file that proves it holds up.

What you will learn in the course

This lesson is part of the course Add a database, authentication and payments to your app

  • Decide what stays in the browser and what must move to the server, and choose a back-end platform that fits your app, your budget and your data.
  • Manage environment variables and secrets (public VITE_ variables, secret keys on the server only, .env files kept out of Git, rotation after a leak).
  • Have the agent design a data model and its migrations, then check that data is actually stored and linked to the right user.
  • Write, have written and test Row Level Security rules that guarantee each user only accesses their own data and that plan limits are enforced in the database.
  • Add sign-up, sign-in, sign-out and password reset, and verify the flows, email confirmation and redirect URLs.
  • Integrate Stripe Checkout in test mode (product, price, session created on the server, test cards) without exposing the secret key.
  • Hold payment status on the server with signed, deduplicated Stripe webhooks, tested with the Stripe CLI or the Dashboard.
  • Apply GDPR basics (information, account deletion, processors) and a go-live checklist before taking real payments.
