Fedify: an ActivityPub server framework

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 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 & HTTP Message Signatures
• Object Integrity Proofs & Linked Data Signatures
• Middlewares for handling webhooks
• NodeInfo protocol
• Enhanced interoperability with Mastodon and other popular fediverse software
