Github Webhooks Filter

A Github Webhooks filter that lets you select as you want your webhooks events

Installation

• Clone the repo
• Install the dependencies with npm install
• Build the app with npm run build
• Run the app with npm start. You need to define the environment variable WEBHOOK_URL, which is the url to send the filtered webhooks to.
• Add a webhook on your Github repository or organization. The Payload URL should be the url where this application run, and the Content type should be set as application/json. Choose Send me everything for the events trigger as this application will filter the events.

And you are done ! Now you can edit the fully typed file filterConfiguration.json, to filter as you would like your webhooks.

You can find all the possible events here: https://docs.github.com/en/developers/webhooks-and-events/webhooks/webhook-events-and-payloads

Development

If you want to test locally, you will need to redirect the webhook sent by Github to your local server. One solution is to use ngrok, as explained in the Github's documentation: https://docs.github.com/en/developers/webhooks-and-events/webhooks/creating-webhooks#exposing-localhost-to-the-internet.

You can also have access to the recent deliveries of a webhook, as explained here: https://docs.github.com/en/developers/webhooks-and-events/webhooks/testing-webhooks.

To generate new events json schema, add them to the file events/index.ts and run the command npm run generate-schemas.
