# Task Management Tool

A FastAPI-based task management system that allows you to create, read, update, and delete tasks.

## Features

- **CRUD Operations**: Create, read, update, and delete tasks
- **Task Properties**: Each task has a title, description, completion status, and priority level
- **SQLite Database**: Data persistence using SQLite with SQLAlchemy ORM
- **API Documentation**: Automatic API documentation with Swagger UI
- **Health Check**: Built-in health check endpoint
- **CORS Support**: Cross-origin resource sharing enabled

## API Endpoints

### Base Endpoints
- `GET /` - API information and links
- `GET /health` - Health check endpoint
- `GET /docs` - Swagger UI documentation
- `GET /redoc` - ReDoc documentation
- `GET /openapi.json` - OpenAPI specification

### Task Endpoints
- `POST /tasks/` - Create a new task
- `GET /tasks/` - Get all tasks (with pagination)
- `GET /tasks/{task_id}` - Get a specific task by ID
- `PUT /tasks/{task_id}` - Update a specific task
- `DELETE /tasks/{task_id}` - Delete a specific task

## Installation and Setup

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

2. Run the application:
   ```bash
   uvicorn main:app --host 0.0.0.0 --port 8000
   ```

The application will be available at http://localhost:8000

## Task Model

Each task has the following properties:
- `id`: Unique identifier (auto-generated)
- `title`: Task title (required)
- `description`: Task description (optional)
- `completed`: Completion status (default: false)
- `priority`: Priority level - "low", "medium", "high" (default: "medium")
- `created_at`: Creation timestamp (auto-generated)
- `updated_at`: Last update timestamp (auto-updated)

## Environment Variables

No environment variables are required for basic operation. The application uses SQLite database stored at `/app/storage/db/db.sqlite`.

## Database

The application uses SQLite database with Alembic for migrations. The database will be automatically created when the application starts.

## Development

- Database models are in `app/models/`
- API routes are in `app/routers/`
- Pydantic schemas are in `app/schemas/`
- Database configuration is in `app/db/`

## Health Check

The `/health` endpoint provides information about the application and database status:
- Returns service status
- Checks database connectivity
- Provides error information if issues are detected
