I'm happy to announce that my barebones ActivityPub server, implemented in Node.js/Express, is now open source! I intend for it to be a reference implementation for developers who are adding ActivityPub to their own services, but also it is an application server that you can build on if you want.

In other words, t's a few hundred lines of code that lets you create Mastodon-compatible accounts that can accept follow requests and post stuff to their followers.

I actually built a little toy service (that I will also eventually open source) which converts any RSS feed to an ActivityPub actor that you can subscribe to in Mastodon (or any other AP-compatible client).

Play with it if you like! It is SUPER rough and most feeds end up horribly rendered in Mastodon but it's still kinda cool to see it work: bots.tinysubversions.com/conve

Thanks for building this.

I set up @Algot

and then did a feed update.

As yet, the account has not displayed anything via the Mastodon web client.

@Algot Did you follow the account? Its updates will only appear in your notifications feed because there is no persistence for a "profile" page with a list of posts (yet)

Follow

@darius

I see the profile page but have had no notifications.

I did follow the account and can see the account (with a nice avatar image built from my RSS header graphic - COOL!)
