- **Alembic**: Database migration tool
- **SQLite**: Lightweight disk-based database
- **Pydantic**: Data validation and settings management
- **Uvicorn**: ASGI server for FastAPI

   ```

2. Install dependencies:
   ```
   pip install -r requirements.txt

## API Endpoints

### Health Check
- `GET /health` - Check if the API is running

### Todo Operations
- `POST /api/todos/` - Create a new todo
- `GET /api/todos/` - List all todos (with optional filters)
- `GET /api/todos/{todo_id}` - Get a specific todo
- `PUT /api/todos/{todo_id}` - Update a todo
- `DELETE /api/todos/{todo_id}` - Delete a todo

## Example API Usage

### Create a Todo Item
```bash
curl -X 'POST' \
  'http://127.0.0.1:8000/api/todos/' \
  -H 'Content-Type: application/json' \
  -d '{
  "title": "Buy groceries",
  "description": "Milk, eggs, bread",
  "completed": false
}'
```

### Get All Todos
```bash
curl -X 'GET' 'http://127.0.0.1:8000/api/todos/'
```

### Get a Specific Todo
```bash
curl -X 'GET' 'http://127.0.0.1:8000/api/todos/1'
```

### Update a Todo
```bash
curl -X 'PUT' \
  'http://127.0.0.1:8000/api/todos/1' \
  -H 'Content-Type: application/json' \
  -d '{
  "completed": true
}'
```

### Delete a Todo
```bash
curl -X 'DELETE' 'http://127.0.0.1:8000/api/todos/1'
```

## Database

The application uses SQLite with the database file stored at `/app/storage/db/db.sqlite`.

## Migrations

Migrations are handled with Alembic:

```bash
# Apply migrations
alembic upgrade head

# Create a new migration
alembic revision --autogenerate -m "Description of changes"
```
