Bluesky Feed Bot is a GitHub Action for posting RSS feeds to Bluesky via GitHub Actions workflows.

1. Go to https://bsky.app/settings/app-passwords and add a new app password.

   • Name it whatever you want.
   • Save it and grab the app password. For security reasons, you won't be able to view this again. If you lose this app password, you'll need to generate a new one.

2. Create a new GitHub repository.

3. Go to your repository settings at https://github.com/${YOUR_REPO}/settings/secrets/actions/new, and add a new secret with the value of the access token.

4. Add a file named .github/workflows/blueskyfeedbot.yml with the following content:

   name: FeedBot
   on:
     schedule:
       # This will run every five minutes. Alter it using https://crontab.guru/.
       - cron: '*/5 * * * *'
     workflow_dispatch: # This allows manually running the workflow from the GitHub actions page
   concurrency:
     group: feedbot
   jobs:
     rss-to-bluesky:
       runs-on: ubuntu-latest
       steps:
         - name: Generate cache key
           uses: actions/github-script@v6
           id: generate-key
           with:
             script: |
               core.setOutput('cache-key', new Date().valueOf())
         - name: Retrieve cache
           uses: actions/cache@v3
           with:
             path: ${{ github.workspace }}/blueskyfeedbot
             key: feed-cache-${{ steps.generate-key.outputs.cache-key }}
             restore-keys: feed-cache-
         - name: GitHub
           uses: 'joschi/blueskyfeedbot@v1'
           with:
             # This is the RSS feed you want to publish
             rss-feed: https://www.githubstatus.com/history.rss
             # Template of status posted to Bluesky (Handlebars)
             template: |
               {{item.title}}
   
               {{item.link}}
             # This is your service URL (optional)
             service-url: https://bsky.social
             # This is the Bluesky username (example: username.bsky.social)
             username: ${{ secrets.BLUESKY_USERNAME }}
             # This is the app password you created earlier
             password: ${{ secrets.BLUESKY_PASSWORD }}
             # This is a path to the cache file, using the above cache path
             cache-file: ${{ github.workspace }}/blueskyfeedbot/cache.json
             # The maximum number of posts created on the first run
             initial-post-limit: 10
             # Maximum number of XML entity expansions allowed when parsing feeds (0 = unlimited)
             # xml-entity-expansion-limit: 10000

5. Commit and publish your changes.

The status template (status-template) is using Handlebars as template engine.

The action is passing in an instance of FeedData (field feedData) and the current FeedEntry (field item) into the template:

export interface FeedEntry {
  link?: string;
  title?: string;
  description?: string;
  published?: Date;
}

export interface FeedData {
  link?: string;
  title?: string;
  description?: string;
  generator?: string;
  language?: string;
  published?: Date;
  entries?: Array<FeedEntry>;
}
