Activitypub is decentralized social networking protocol recommended by the W3C. It provides a client to server API for creating, updating and deleting content, as well as a federated server to server API for delivering notifications and content. As part of the work on Lemmy, we have implemented some high-level abstractions for handling the server-to-server protocol in Rust. These abstractions are now available as a standalone library.
The main features are:
Documentation is currently lacking. If you want to get started with the library, best look at the example.
The code has already been used in production as part of Lemmy for a long time, without any notable problems. However, ergonomics are lacking and need to be improved. There are also many additional features which would be worth implementing. See the project readme for details. Contributions and suggestions are very much welcome!
