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:

• Type-safe objects for Activity Vocabulary (including some vendor-specific extensions)
• #WebFinger client and server
• HTTP Signatures & Linked Data Signatures & Object Integrity Proofs
• Middleware for handling webhooks
• #NodeInfo protocol
• #Node.js, #Deno, and #Bun support
• CLI toolchain for testing and debugging

If you're curious, take a look at the #Fedify website! There's comprehensive docs, a demo, a tutorial, example code, and more:

https://fedify.dev/

In the next version of #Fedify, the Article, ChatMessage, Note, and Question classes will have a quoteUrl property. This property corresponds to the following three JSON-LD properties all at once:

• as:quoteUrl
• misskey:_misskey_quote
• fedibird:quoteUri

Available for preview in version 0.15.0-dev.384+6c39741b (JSR & npm).

Today, thanks to @ellemedit, we've added two more example projects to #Fedify!

• Express integration example
• Next.js integration example

If you're interested in Fedify and these two frameworks, take a look!

#ExpressJS #NextJS

As a trilingual, I've written the #Fedify's tutorial in three languages:

• English: https://unstable.fedify.dev/tutorial/microblog
• Korean: https://hackmd.io/@hongminhee/fedify-tutorial-ko
• Japanese: https://zenn.dev/hongminhee/books/4a38b6358a027b

In the next version of #Fedify, it will allow you to decouple actor URIs from WebFinger usernames with the mapHandle() method. For example, you can use UUIDs for actor URIs but let users use their own username of choice for their fediverse handle.

You can preview it in v0.15.0-dev.382+a8a9b73b: JSR & npm.

@antolius Glad you enjoyed reading this!

@fedify this is incredibly helpful! I went into it with some beforehand knowledge & it was still useful.

The structure & flow are great, it's telling a story & leading the reader through it. The tips alone make it worth a read. I love how detailed it is, covering everything from database to frontend. On the other hand, every lib/tool is well & succinctly explained which makes it easy to swap out with an alternative. The prompts for improvements at the end are great.

⭐⭐⭐⭐⭐, will read again.

Thank you for your advice. As you mentioned, Fedify currently has actor URIs consisting of handles. This limitation is due to the early design of Fedify and will be fixed before we release v1.0!

한국어판 Fedify 튜토리얼 《나만의 연합우주 마이크로블로그 만들기》를 공개합니다! Fedify나 ActivityPub을 몰라도 차근차근 따라할 수 있게 되어 있으니, ActivityPub 구현에 관심이 있으신 분들은 부디 읽어 주시기 바랍니다. (대신, 조금 깁니다. 😅)

We just finished drafting a new tutorial for #Fedify! This tutorial will walk you through the steps of creating your own federated #microblog. It's pretty long, though.

Please read it, give us feedback, and have fun!

The next version of #Fedify will add the Context.lookupObject() method, which is preferred over the global lookupObject() function.

Are there any features you'd like to see in #Fedify?

Question for those who have followed the #Fedify tutorial: How long did it take you to follow the tutorial?

#fedidev

I finally finished the first draft of the new #Fedify tutorial, but it's still in Korean. Now I just need to polish it up and translate it into English.

#fedidev

Did you know? #Fedify offers the markdown-it plugins for parsing #Mastodon-style mentions and hashtags syntax:

• @fedify/markdown-it-mention: JSR & npm
• @fedify/markdown-it-hashtag: JSR & npm

Check it out!

Released #Fedify 0.14.2 & 0.13.3, which fix an incompatibility issue with Meta's Threads where sent activities had not been verified by their inbox.

• Fedify 0.14.2: JSR & npm
• Fedify 0.13.3: JSR & npm

Released Fedify 0.14.1 & 0.13.2, which fix a few bugs in the fedify inbox command:

This frustration later became the impetus for creating @fedify:

https://todon.eu/@hongminhee/110971265294250919

We've released v0.14.0 of #Fedify, the #ActivityPub server framework, with the following key changes:

• It is now possible to set the recipient of the sendActivity() method to "followers" in just the Context instead of the RequestContext.
• Improved performance of the Object.toJsonLd() method by about 3,000 times.
• Added source property to Object.
• Added aliases property to Actor, corresponding to ActivityPub's alsoKnownAs property.
• fedify init command now adds default compilerOptions settings to tsconfig.json and deno.json.

Fedify v0.14.0 is available from JSR and npm. See also the full changelog for details.

Happy #fedidev!

We've added the Inspecting ActivityPub objects section to the #Fedify docs, introducing BrowserPub and the fedify lookup command!

Do you know that? Some of the properties in Activity Vocabulary have been renamed in #Fedify's JavaScript APIs. Below are some examples:

• alsoKnownAs → aliases
• publicKeyPem → publicKey
• hreflang → language
• publicKeyMultibase → publicKey
• orderedItems → items
• oneOf → exclusiveOptions
• anyOf → inclusiveOptions
• votersCount → voters
• attributedTo → attributions
• inReplyTo → replyTargets

I'm sharing a prototype of #Fedify written in #Python, codenamed “FediKit.” Many of the ideas for Fedify were already implemented in this prototype, albeit in a different language.

@cybertailor @oleg_ru

Касаясь систем управления контентом с поддержкой #ActivityPub, хотелось бы отметить и библиотеку для построения собственного федеративного сервера @fedify. Отлично подходит, когда "все эти ваши вордпрессы мне нафиг не сдались". :blobcatmeltthumbsup:

#Fedify

For educational purpose, I've created a federated microblog example using #Fedify, with a total of about 30 commits, which you can follow step by step.

Now, I'm starting to write a hands-on Fedify tutorial based on this example code. I'll make it public when I'm done!
