activitypub.js

An opinionated, practical and useful implementation of the ActivityPub spec

WARNING, this is VERY early stage and doesn't work yet.

Goals

• Fully interoperable with existing ActivityPub implementations (e.g. Mastodon)
• Complete, covering Client to Server and Server to Server
• Well tested
• Vanilla and opinionated
• Includes applied security best practices
• Straightforward to drop in to another node app or bootstrap from
• Full federation support

What does this do?

Running this application will give you an application API that supports all of the standard ActivityPub requirements for a full social app including WebFinger, ActivityPub, ActivityStreams, Actors, Authentication and basic app features. You can then extend or modify this to create pretty much any social application you can think of.

See [some examples](##Try It) of what you can do out of the box.
