Fert Recon

React + Vite + Leaflet frontend and FastAPI backend for Morocco fertilizer recommendations and EE-powered maps.

Frontend

npm install
npm run dev           # localhost:5173

Set VITE_API_BASE to point at your backend in prod (defaults to /api locally).

Backend

python -m venv .venv
source .venv/bin/activate
pip install -r server/requirements.txt
uvicorn server.main:app --host 0.0.0.0 --port 8000

Provide EE creds via GOOGLE_APPLICATION_CREDENTIALS (or upload through /api/auth/service-account in the UI). Ensure public/data/fertimap_grid.csv and server/fertimap_rf_models.joblib are present; retrain surrogates with:

python - <<'PY'
from server.fertimap_service import train_local_models
train_local_models()
PY

Deploy hints

• Frontend: build npm run build (output dist), serve statically; set VITE_API_BASE=https://your-backend.
• Backend: deploy uvicorn server.main:app (Railway/Fly/Render/etc.), install server/requirements.txt, keep model/data files accessible, add EE auth env vars.
