## Database
|
||||
## 💾 Database
|
||||
|
||||
The application uses SQLite database stored at `/app/storage/db/db.sqlite`. The database is automatically created when the application starts.
|
||||
**Storage Location**: `/app/storage/db/db.sqlite`
|
||||
|
||||
## Author
|
||||
The application uses SQLite for simplicity and portability. The database is automatically created on first run, with tables managed through Alembic migrations.
|
||||
|
||||

|
||||
**Todo Schema:**
|
||||
- `id`: Primary key (auto-increment)
|
||||
- `title`: Todo title (required)
|
||||
- `description`: Optional description
|
||||
- `completed`: Completion status (default: false)
|
||||
- `created_at`: Creation timestamp
|
||||
- `updated_at`: Last modification timestamp
|
||||
|
||||
## 🔧 Development
|
||||
|
||||
### Running Tests
|
||||
```bash
|
||||
# Add your test command here when tests are implemented
|
||||
pytest
|
||||
```
|
||||
|
||||
### Code Quality
|
||||
```bash
|
||||
# Lint and format code
|
||||
ruff check --fix .
|
||||
```
|
||||
|
||||
### Database Management
|
||||
```bash
|
||||
# Create new migration
|
||||
alembic revision --autogenerate -m "description"
|
||||
|
||||
# Apply migrations
|
||||
alembic upgrade head
|
||||
|
||||
# Rollback migration
|
||||
alembic downgrade -1
|
||||
```
|
||||
|
||||
## 📦 Deployment
|
||||
|
||||
For production deployment, consider:
|
||||
|
||||
1. **Environment Variables**: Configure database URL and secrets
|
||||
2. **Process Manager**: Use Gunicorn with Uvicorn workers
|
||||
3. **Reverse Proxy**: Place behind Nginx or similar
|
||||
4. **Database**: Migrate to PostgreSQL for production workloads
|
||||
|
||||
Example production command:
|
||||
```bash
|
||||
gunicorn main:app -w 4 -k uvicorn.workers.UvicornWorker
|
||||
```
