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 Question about licensing: the readme says MIT at the end, but there's no normal slightly tweaked MIT LICENSE file, and the package.json says ISC. What's it under?
@bb010g I meant for it to be MIT, will fix
@bb010g Okay, all fixed!
