# Mitgliederladen
## Development branches
backend
: Server component, using Rust/SQL, offering API (via HTTP/2?)
db_scripts
: SQL scripts
main
: frontend client as flutter app
## Tech used
### Backend
- Database connection using Rust-lang and SQLx
- RESTful (Level 2, JSON over RPC) API using Rust-lang (and probably (actix web framework)[https://actix.rs] plus (utoipa\[sic! 🍺 beer-branded punny name\])[https://github.com/juhaku/utoipa]
## Frontend
- Google Flutter using Dart.
Target platforms?
- probably Android[^1], iOS[^2].
- Debug target could be desktop for fastest deployment. Production targets: Perhaps desktop and/or web, if wanted.
[1]: via APK? Via Play Store or F-Droid? Then Registration as Play store developer (for charity or one time purchase with credit card?) needed.
[2]: Registration as Apple developer for charity needed.
