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.
Fedify supports Node.js, Bun, and Deno. We recommend using the latest version of Node.js for the best 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
- Integration with various web frameworks
- CLI toolchain for testing and debugging
