Backend From Zero

Let's read the map together

Look at this with us. Don't open the editor yet. By the end of the day you will be able to point at every box and say what it does.

Follow the arrows with your finger:

  1. You (browser or curl) hit a public address — a public IP is enough. A domain like api.sreecharandesu.in is optional
  2. Nginx + Certbot on one Ubuntu machine. Port 4000 stays closed. The world talks to 80/443
  3. Express — our API, kept alive by PM2 (club-api)
  4. Neon (Postgres) through Prisma — members and one-time mail tokens
  5. Amazon SES — verify and reset mail. Sandbox: From and To must be verified identities
  6. GitHub Actions — a push SSHs into the box, writes your whole .env, restarts PM2

Your laptop runs the same API on localhost:4000. Live is the same git repo. Two .env files. One Neon project.

We will build this, not screenshot it. When you need a second look, the finished code is public: https://github.com/sreecharan-desu/club-portal-backend — open it after you have tried the step, so you still understand each file.
