This repo is just the back-end: TypeScript and Prisma with PostgreSQL. Express for routing, Pino for logging and Vine for validation.
Prisma is the ORM, handling database schemas and relations, including data integrity, indexing and cascading deletes.
Image processing is handled via Sharp. Image uploads are validated and compressed server-side, using magic-bytes to determine file type.
This runs on a VPS with Caddy for the reverse proxy. Kept alive with a systemd service. Docker containerizes the database.
I have a self-hosted instance of Uptime Kuma to monitor uptime, integrated with ntfy so I get a phone notification if something goes wrong.
The front-end is an iOS app written in Swift.
To keep related concerns together, I went for an entity-based folder structure. Each entity gets their own model, controller, router, schema and test file.
Authentication is handled with token-based sessions issued on login and checked with each request. No cookies since this is iOS-only. Registration requires invitation codes generated by existing members.
