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.

@darius thanks again for this, Darius - humming right along on the raspberry pi 3 I set up as a dev system for my fork of your code  gimme a few days to knock a couple more of my ideas into it and maybe I'll be able to return the favor a bit ;)
@djsundog Fantastic!! This is all I wanted :)
