3D-Printly

A small full-stack web app for a fictional 3D-printing service based in Bern. Customers submit print requests through a public landing page (in German); an admin dashboard lists, adds, edits, and deletes those submissions.

The whole thing runs as a single docker compose stack and is exposed to the internet through a Cloudflare tunnel — no port forwarding, no public IP.

Stack

• Apache — serves the static site and reverse-proxies /api/* to Node. Handles basic auth on /admin.html and the admin API routes.
• Node + Express — small JSON API for the contact form and admin CRUD.
• MariaDB — stores submissions.
• Cloudflared — outbound-only tunnel; nothing is exposed on the host.
