## Installation
|
|
|
|
1. Clone the repository
|
|
2. Install dependencies:
|
|
|
|
```bash
|
|
pip install -r requirements.txt
|
|
```
|
|
|
|
## Database Setup
|
|
|
|
The application uses SQLite, and the database will be created automatically at `/app/storage/db/db.sqlite` when the application starts.
|
|
|
|
## Running the Application
|
|
|
|
```bash
|
|
uvicorn main:app --reload
|
|
```
|
|
|
|
The API will be available at http://localhost:8000
|
|
|
|
## API Documentation
|
|
|
|
Once the application is running, you can access the API documentation at:
|
|
|
|
- Swagger UI: http://localhost:8000/docs
|
|
- ReDoc: http://localhost:8000/redoc
|
|
|
|
## API Endpoints
|
|
|
|
### Health Check
|
|
|
|
- `GET /health` - Check if the API is running
|
|
|
|
### Todo Operations
|
|
|
|
- `GET /todos/` - List all todos (supports pagination and filtering by completion status)
|
|
- `POST /todos/` - Create a new todo
|
|
- `GET /todos/{todo_id}` - Get a specific todo
|
|
- `PUT /todos/{todo_id}` - Update a todo
|
|
- `DELETE /todos/{todo_id}` - Delete a todo
|
|
|
|
