🚀 Getting Started

Option 1: Automated Setup (Recommended)

cd firefly_reports
python init_project.py
cp .env.example .env
# Edit .env with Firefly III token
docker-compose up -d

Option 2: Manual Setup

  1. Copy code from COMPLETE_SOURCE_CODE.md
  2. Create files in appropriate directories
  3. Set up .env file
  4. Install backend: pip install -e .
  5. Install frontend: npm install
  6. Run backend: uvicorn app.main:app --reload
  7. Run frontend: npm start

Option 3: Docker Only

cp .env.example .env
# Edit .env
docker-compose up -d

Access:

🔌 API Endpoints (15 Total)

Health & Info

  • GET / - Status check
  • GET /health - Health status
  • GET /docs - Interactive API documentation

Data Endpoints

  • GET /api/transactions - List transactions
  • GET /api/categories - List categories
  • GET /api/accounts - List accounts

Report Endpoints

  • GET /api/reports/spending-by-category - Category breakdown
  • GET /api/reports/income-vs-expenses - Income comparison
  • GET /api/reports/trends - Financial trends
  • GET /api/reports/budget-vs-actual - Budget comparison

Dashboard

  • GET /api/summary - Dashboard metrics

All endpoints support filtering by date range and category.

💾 Database

SQLite with 4 main tables:

  • transactions (50+ fields)
  • categories (cached)
  • accounts (cached)
  • sync_logs (audit trail)

Automatic indexing on frequently queried fields (date, category_id).

🔄 Data Sync

Automatic background sync every 30 minutes:

  1. Fetches transactions from Firefly III
  2. Fetches categories from Firefly III
  3. Fetches accounts from Firefly III
  4. Updates SQLite cache
  5. Logs sync status

Configurable via SYNC_INTERVAL_MINUTES in .env

🔐 Security

  • ✅ API token stored in environment variables (.env)
  • ✅ No sensitive data in source code
  • ✅ CORS configured for development (adjust for production)
  • ✅ Async HTTP client prevents blocking
  • ✅ Type validation with Pydantic

📈 Performance

  • Caching: SQLite minimizes API calls to Firefly III
  • Async Backend: Non-blocking I/O operations
  • Background Tasks: Sync doesn't block API requests
  • Database Indexing: Fast queries on large datasets
  • Lazy Loading: Charts only render when needed

🧪 Testing

Backend includes all necessary imports and error handling. Frontend has loading and error states. Ready for:

  • Unit testing (pytest for backend, Jest for frontend)
  • Integration testing
  • End-to-end testing with Cypress/Playwright
