My new laravel-activitypub library is really coming along, and I will be using it for Loops and eventually Pixelfed.
It leverages a lot of Laravel magic to handle many aspects of federation, you simply have to map a few models and attributes in the config file, and it will work with new and existing laravel projects!
Just imagine adding ActivityPub support to your app, while only writing less than 10 lines of code.
It's Magic ✨
