Explanation

Instead of having a single Discord channel for all your GitHub repository feeds, or having a separate tech channel for each repository, you can use this worker to create a forum post for each repository and sort your GitHub activity into those forum posts individually. This way, you can have a single channel for all your GitHub activity, but still keep it organized by repository - and users can easily follow the forum posts that they are interested in.

Setting up with Cloudflare Workers

1. Deploy to Cloudflare Workers using the button above.
2. Insert the environment variables listed in the wrangler.toml file. You can either use the wrangler command, or do it through the worker dashboard.
3. Add your new worker URL (https://gitcord-forum.WORKER_SUBDOMAIN.workers.dev/) as a webhook in your GitHub repository settings with your preferred set of notifications to get from the repository. Make sure to set content type to application/json and also match the secret you set in the environment variables.
   • You can also add this URL as a webhook for your entire GitHub organization!

    W->>W: Find thread ID for repository

    alt no forum thread exists
        W->>D: Create a new forum thread and send first message
        D->>W: Return message data with thread ID
