PyPi Notifier

A script to notify you about new releases of Python packages via Discord webhooks. The script checks for updates on the specified packages at regular intervals, stores the information in a SQLite database, and sends notifications when a new version is released.

Upon initial launch, no notifications will be sent until a new update is detected.

Supported Notification Clients:

• Discord

Prerequisites

• Python 3.10 or higher
• Docker (if using Docker setup)

Setup

Options for Use

• Docker
• Package

Running the Script as a Package

1. Install the package

   poetry add pypi-notifier
   # or
   pip install pypi-notifier
   

2. Use in your Python code

   from pypi_notifier import PyPiNotifier
   notifier = PyPiNotifier(
        discord_webhook="https://discord.com/api/webhooks/...",
        tracked_packages={
            "PySide6": "https://pypi.org/rss/project/PySide6/releases.xml",
            "TkFontSelector": "https://pypi.org/rss/project/tkfontselector/releases.xml",
        },
        cron_schedule="0 * * * *",  # Cron schedule format for checking updates every hour
   )
   
   # Run the notifier once
   notifier.run()
   
   # Or run continuously as scheduled by cron
   notifier.run_forever()
   

Running the Docker Container

To run the Docker container with the appropriate environment variables, use the following command:

docker run -e "DISCORD_WEBHOOK=<your_webhook_url>" -e "TRACKED_PACKAGES=<your_tracked_packages_json>" -e "CRON_SCHEDULE=0 * * * *" -v "app_data:/app_data"

• Replace <your_webhook_url> with your Discord webhook URL.
• Replace <your_tracked_packages_json> with the JSON string of your tracked packages, for example:

{
  "PySide6": "https://pypi.org/rss/project/PySide6/releases.xml",
  "TkFontSelector": "https://pypi.org/rss/project/tkfontselector/releases.xml"
}

This command will mount the app_data volume to persist the database and logs across container restarts.

Checking Logs

Outside of Docker, you can view the logs in ./app_data/logs/.

Notes

• The app_data volume is used for persistent storage, including the SQLite database and logs.
• If you're running the script outside Docker, the app_data folder will be created in your local directory to store logs and the database.
• The cron_schedule format follows standard cron syntax for scheduling tasks. For example, 0 * * * * runs the script every hour.
• If no updates are detected for a package, no notifications will be sent until a newer version is found.

Troubleshooting

• Error Logs: If something goes wrong, check the logs at ./app_data/logs/ for more details.
• Database Issues: Ensure that the SQLite database is properly initialized and accessible.
