A web-based task scheduler built with FastAPI and Jinja2 that allows you to schedule, view, and delete tasks using different trigger types (date, interval, cron). Tasks are stored in a SQLite database and executed in the background.
- Web UI: Schedule tasks using a simple web interface.
- Trigger Types: Supports one-time (date), interval, and cron-style scheduling.
- Task Management: View all scheduled tasks and delete them as needed.
- Persistent Storage: Tasks are stored in a SQLite database.
- Concurrent Execution: Uses threading to run the web server and task executor simultaneously.
- Error Handling: User-friendly error messages for invalid input.
- Python 3.8+
