I started a new project, the federails gem. It’s a Rails engine, so it will be usable in Rails projects, which will provide the basic endpoints for an ActivityPub application. In addition, it will give the tools to publish data from the application in an ActivityPub format.
It’s a real work in progress, as I have to include the work from the proof of concept and adapt it in the engine.
Maybe we should start a new thread to discuss about the whats and hows you want to use it ?
EDIT: Discussion started here.
