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:
|
||||||
|

|
||||||
|

|
||||||
|

||||||

|
||||||
|

||||||

|
||||||

|
||||||
|
mastodonInstance: "https://social.lol"
|
||||||
|
mastodonToken: ${{ secrets.MASTODON_TOKEN }}
|
||||||
|
testMode: true
|
||||||
|

|
||||||
|

|
||||||
|
- 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.
