+After posting and [discussing](https://social.lol/@nhoizey@mamot.fr/110101373765987885) [my post from yesterday](/posts/2023/automate-syndicate-content-mastodon-eleventy/) with [Nicolas Hoizey](https://nicolas-hoizey.com/) I decided to explore his suggested path and explore using a GitHub action to handle posts to Mastodon, rather than Make.<!-- excerpt --> Nicolas, thankfully, [has an action that supports exactly this path](https://github.com/marketplace/actions/any-feed-to-mastodon). It currently supports JSON feeds, [with planned support for Atom/RSS](https://github.com/nhoizey/github-action-feed-to-mastodon/issues/16).[^1]
+
+For now, to surface my Eleventy activity feed as JSON, we peak under the hood of [`@11ty/eleventy-activity-feed`](https://www.npmjs.com/package/@11ty/eleventy-activity-feed) and, rather than calling `toRssFeed`, call `getEntries` and use the merged feed data it returns as JSON to construct a [`follow.json`](https://coryd.dev/follow.json) feed in [`src/_data/follow.js`](https://github.com/cdransf/coryd.dev/blob/66085dfdb1fab7bd46b8aa3e4b5e40ced906fb93/src/_data/follow.js)[^2]
+
+```javascript
+module.exports = async function () {
+  const { ActivityFeed } = await import('@11ty/eleventy-activity-feed')
+  const feed = new ActivityFeed()
+  feed.addSource('atom', 'Blog', 'https://coryd.dev/feed.xml')
+  feed.addSource('rss', 'Letterboxd', 'https://letterboxd.com/cdme/rss')
+  feed.addSource('rss', 'Glass', 'https://glass.photo/coryd/rss')
+  feed.addSource('rss', 'Oku', 'https://oku.club/rss/collection/NvEmF')
+  const entries = feed.getEntries()
+  const res = await entries
+  const activity = { posts: [] }
+  res.forEach((entry) =>
+    activity.posts.push({
+      id: entry.url,
+      title: entry.title,
+      url: entry.url,
+      content_html: entry.content || '',
+      date_published: entry.published,
+    })
+  )
+  return activity
+}
+```
+
+We can then render this to our desired feed in [`follow.11ty.liquid`](https://github.com/cdransf/coryd.dev/blob/66085dfdb1fab7bd46b8aa3e4b5e40ced906fb93/src/follow.11ty.liquid):
+
+{% raw %}
+
+```json
+---
+permalink: '/follow.json'
+---
+{% assign posts = follow.posts %}
+{
+"version": "https://jsonfeed.org/version/1",
+"title": "All activity • Cory Dransfeldt",
+"icon": "https://coryd.dev/static/images/avatar.webp",
+"home_page_url": "https://coryd.dev",
+"feed_url": "https://coryd.dev/follow.json",
+"items": [{% for item in posts %}
+  {
+  "id": "{{ item.id }}",
+  "title": "{{ item.title }}",
+  "url": "{{ item.url }}",
+  "content_html": "",
+  "date_published": "{{ item.date_published | date: "%Y-%m-%dT%H:%M:%S-08:00" }}"
+  }{% if not forloop.last %},{% endif %}
+{% endfor %}
+]
+}
+```
+
+{% endraw %}
+
+Finally, we skip the Make-dependent portion of this exercise and leverage a [cron-based action](https://github.com/cdransf/coryd.dev/blob/66085dfdb1fab7bd46b8aa3e4b5e40ced906fb93/.github/workflows/scheduled-post.yaml#L21):
+
+```yaml
+name: Scheduled follow feed to Mastodon
+on:
+  schedule:
+    - cron: '0 * * * *'
+jobs:
+  JSONFeed2Mastodon:
+    runs-on: ubuntu-latest
+    steps:
+      - name: Checkout
+        uses: actions/checkout@v3
+      - name: Feed to Mastodon
+        uses: nhoizey/github-action-feed-to-mastodon@v2
+        with:
+          feedUrl: "https://coryd.dev/follow.json"
+          mastodonInstance: "https://social.lol"
+          mastodonToken: ${{ secrets.MASTODON_TOKEN }}
+          testMode: true
+      - name: Pull any changes from Git
+        run: git pull
+      - name: Commit and push
+        uses: stefanzweifel/git-auto-commit-action@v4
+```
+
+GitHub will now check the `follow.json` feed and post updates hourly.
+
+[^1]: This is also the part where I should make the time to try and add support for this and contribute the change.
+[^2]: The JSON Feed site [provides a validator](https://validator.jsonfeed.org/) and this feed validates, but I'm returning an empty `content_html` field to satisfy their schema. This is in large part because returning properly sanitized and formatted html inside a string got messier than I would have liked and is not strictly necessary for my purposes here.
