# Task Manager API

A simple task management API built with FastAPI and SQLite.

## Features

- Create, read, update, and delete tasks
- Task priority levels (high, medium, low)
- Task completion status tracking
- RESTful API design
- Automatic API documentation with Swagger UI

## Quick Start

1. Install dependencies:
   ```bash
   pip install -r requirements.txt
   ```

2. Run database migrations:
   ```bash
   alembic upgrade head
   ```

3. Start the application:
   ```bash
   uvicorn main:app --reload
   ```

4. Open your browser and navigate to:
   - API Documentation: http://localhost:8000/docs
   - Alternative Documentation: http://localhost:8000/redoc
   - Health Check: http://localhost:8000/health

## API Endpoints

### Base Routes
- `GET /` - API information and links
- `GET /health` - Health check endpoint

### Task Management
- `GET /api/v1/tasks` - Get all tasks (with pagination)
- `GET /api/v1/tasks/{id}` - Get a specific task
- `POST /api/v1/tasks` - Create a new task
- `PUT /api/v1/tasks/{id}` - Update a task
- `DELETE /api/v1/tasks/{id}` - Delete a task

## Task Schema

```json
{
  "title": "string",
  "description": "string (optional)",
  "completed": "boolean (default: false)",
  "priority": "string (default: medium)",
  "id": "integer (auto-generated)",
  "created_at": "datetime (auto-generated)",
  "updated_at": "datetime (auto-generated)"
}
```

## Database

The application uses SQLite for data storage. The database file is created automatically at `/app/storage/db/db.sqlite`.

## Development

The application is configured with:
- CORS enabled for all origins
- Automatic API documentation
- Database migrations with Alembic
- Pydantic models for request/response validation
