Fedify is a TypeScript library for building federated server apps powered by ActivityPub and other standards, so-called fediverse. 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.

Fedify is an #ActivityPub server framework in #TypeScript & #JavaScript. 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.
The key features it provides currently are:
If you're curious, take a look at the #Fedify website! There's comprehensive docs, a demo, a tutorial, example code, and more:

@fedify/markdown-it-hashtag, a markdown-it plugin that parses and renders Mastodon-style #hashtags, just released 0.3.0! In this release, link, linkAttributes, and label callbacks became to take one more parameter, a markdown-it environment, which enables your hashtag rendering more flexible. For example, now hashtag links can be dynamically determined:
import MarkdownIt from "markdown-it";
import { hashtag } from "@fedify/markdown-it-hashtag";
const md = new MarkdownIt();
md.use(hashtag, {
link: (tag: string, env: any) => `${env.origin}/tags/${tag.substring(1)}`
});
const html = md.render("Your Markdown text with #hashtags!", {
origin: "https://example.com"
});
@fedify/markdown-it-hashtag 0.3.0 is available at both JSR and npm!

This is great - @fedify has launched an @opencollective to help sustain the project. This is a great library and framework that is helping many other projects grow into the #fediverse. Shout-out to @hongminhee! (also to @liaizon for posting about it as well)
@liaizon@social.wake.st
Today @fedify launched an @opencollective to support the project.
@hongminhee has been doing amazing work on it. 
Fedify has shown itself to be one of the most promising ways for other projects to become part of the #fediverse. If you liked seeing Ghost (@index) make such fast progress bringing in potentially thousands (millions?) of blogs and newsletters to the fediverse, this is what they are using behind the scenes! So lets support this project together!

FediAuth、apsigが地味に未完成 (ActorのJSON-LDの問題もあるだろうけどFedify Inboxでの検証が通らない)なのでFedify使うことを検討中

Valtteri Laitinen (@valtlai) managed to get #Fedify running on #Cloudflare Workers!

@thisismissem @fedify I got this working with the JSR package by adding a Temporal polyfill and stripping import attributes (see https://github.com/fedify-dev/fedify/issues/161#issuecomment-2618947880).

We've just moved the #Fedify project and related repositories to our new GitHub organization account, @fedify-dev! 🎉
Here's what moved:
All repositories have been transferred and GitHub's automatic redirects are in place, so existing links will continue to work. Also, the project's core functionality and development process remain unchanged.
Thanks to everyone who participated in our naming poll. Looking forward to Fedify's continued growth under its new organizational home!
New GitHub organization: https://github.com/fedify-dev.

Äh… Halusin koodata oman fediverseinstanssin @fedify-kirjastolla. Alustana olisi Cloudflare (Workers, KV, D1, Queues, R2). Workersin Node.js-yhteensopivuustilasta huolimatta Fedify ei kuitenkaan toimi: palauttaa ainakin syntaksivirheitä. Turhauttaa!
Nyt sitten forkkaan Fedifyn toistaiseksi ja yritän saada sen toimimaan. En nimittäin halua ohjelmoida ActivityPub-palvelinta ilman apukirjastoa, enkä mielelläni vaihtaisi hostausympäristöäkään toiseen.

We appreciate the thoughtful suggestions about moving Fedify to platforms like Codeberg that better align with the federation ideals our project upholds. These suggestions raise important points about corporate centralization and the broader FOSS ecosystem that we've carefully considered.
After thorough deliberation, we plan to keep Fedify's primary repository on GitHub for the foreseeable future. This decision stems from several practical considerations:
First, we aim to make Fedify as accessible as possible to potential contributors. While platforms like Codeberg represent important alternatives, GitHub remains the platform most developers are familiar with, particularly in the JavaScript/TypeScript ecosystem where Fedify operates.
Second, GitHub currently provides significant visibility benefits that help us reach more developers who could benefit from or contribute to Fedify. As a relatively new project, this broader reach is particularly valuable for building our community.
Additionally, our package registry JSR's provenance attestation feature, which we rely on for security guarantees, currently only supports GitHub Actions integration. This technical dependency would make migration particularly challenging at this time.
However, we recognize the value in supporting more decentralized platforms. As a middle ground, we are considering setting up a mirror repository on Codeberg. This would provide an alternative access point while maintaining our GitHub presence.
We're committed to regularly reassessing this position as the ecosystem evolves and as alternative platforms continue to mature.

Okay, since we couldn't get in touch with the @fedify account owner, we need a new name for our GitHub organization. Which alternative do you prefer?
Your suggestions for other names are welcome in the comments! We'll make the final decision based on your feedback.

#Fedify already uses the #Temporal API exclusively for representing temporal data.

Here's a quick update on our GitHub organization plans: GitHub support has informed us they no longer process inactive username requests. We'll try reaching out to the current owner of @fedify account to see if we can work something out.
We'll keep you posted on how this goes! 🤞
@fedify@hollo.social
We're planning to move our GitHub repository to an organization account for better project management. We've requested GitHub support to help us acquire the inactive @fedify username for this purpose. (The attached screenshot is our formal request to GitHub support.)
If we successfully acquire @fedify, that will be our new organization name. If not, we'll choose an alternative name. We'll keep you updated on the progress!
In any case, we'll ensure a smooth transition with proper redirects from the current repository. Stay tuned for updates!
