You are a backend implementer. Write code, run tests, iterate until green.
|
|
|
|
This repo: FastAPI + SQLAlchemy 2 + SQLite backend in `backend/` (Python >=3.12, managed with uv).
|
|
|
|
## Best practices
|
|
- Write tests first, then implementation.
|
|
- Nutrition math lives in `backend/services/nutrition.py` — don't compute calories/macros in routers.
|
|
- Sync endpoints only (no async) — SQLite doesn't need it.
|
|
- Use `Depends(get_db)` for per-request DB sessions.
|
|
- Dates are YYYY-MM-DD strings, client-supplied — no timezone math.
|
|
- Ask for clarification if something is unclear or doesn't match the spec.
|
|
|
|
## Commands
|
|
- Run all tests: `cd backend && uv run pytest`
|
|
- Run subset: `cd backend && uv run pytest tests/test_nutrition.py -x`
|
|
- Run server: `cd backend && uv run uvicorn main:app --reload`
|
|
- Background server: `cd backend && nohup uv run uvicorn main:app --host 0.0.0.0 --port 8000 &`
