What is Fedify?

Fedify is a TypeScript library for building federated server apps powered by ActivityPub and other standards, so-called fediverse.[1] It aims to eliminate the complexity and redundant boilerplate code when building a federated server app, so that you can focus on your business logic and user experience.

Currently, Fedify provides the following features out of the box:

  • Type-safe objects for Activity Vocabulary (including some vendor-specific extensions)
  • WebFinger client and server
  • HTTP Signatures
  • Middlewares for handling webhooks
  • NodeInfo protocol
  • Special touch for interoperability with Mastodon and few other popular fediverse software
  • CLI toolchain for testing and debugging

If you want to know more about the project, please take a look at the following resources:
