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:

Visualize your server in the fediverse with the fedify node command and share it with us using the #FedifyNode hashtag!

minat tapi kayaknya terlalu overkill untuk 1 user instance, butuh postgres, redis dll.

It's the output of the fedify node command for fosstodon.org.

The version 1.2.0 of #Fedify, an #ActivityPub server framework, released! The key changes include:

• Added InboxContext.recipient property. It's useful for determining whether it is a shared inbox or a personal inbox, and whose personal inbox is invoked.

• Added getNodeInfo() function, a NodeInfo client.

• Added followedMessage property, which corresponds to _misskey_followedMessage, to Actor type in Activity Vocabulary API.

• Log messages now can be traced using LogTape's implicit contexts, which means you can filter log messages by requestId (an HTTP request identifier) or messageId (a background task identifier).

• Now you can choose an AMQP driver (which supports RabbitMQ) for the message queue in the fedify init command.

• Added the fedify node subcommand, which fetches the given instance's NodeInfo document and visualizes it in neofetch-style.

For details, see the full changelog as well!

Fedify 1.2.0 is available at JSR and npm.

#fedidev

Starting with the next release of #Fedify, v1.2.0, we will support traceable logs for easier debugging. Fedify's traceable logs are implemented using the implicit contexts introduced in LogTape 0.7.0, and most of the logs that Fedify records are given a requestId or messageId. This means that logs can be grouped into requests or background tasks for better analysis.

Want to try it out in advance? Try Fedify v1.2.0-dev.468+2e17cd69 (JSR & npm)!

#fedidev #ActivityPub

The next release of Fedify will introduce the fedify node command, which fetches the NodeInfo of the asked instance and visualizes it in neofetch-style.

If you're running GoToSocial prior to v0.17.0, please, for the love of all good developers sanity, please upgrade.

GoToSocial prior to v0.17.0 had a broken JSON-LD context, which prevents federation from working correctly with some servers (e.g., anything built on Fedify)

The translation of @monaco_koukoku's review on the Japanese version of Creating your own federated microblog:

I read about 70% of the Fedify book on the plane. It was carefully explained step by step, and I could easily understand the contents. Maybe it's because I have researched on implementing ActivityPub before, but I got the impression that I can create it easily. It is also good that there are plenty of ways to check how the implementation works. (I didn't know such a service existed…)

Fedify's only role is to speak ActivityPub, so you need to write your own UI and store data in a database (examples of each are included), but this also means that you can use any UI framework or relational database you like, which opens up a wide range of application possibilities. However, if Fedify does nothing too much, it will just be a hassle, so it is probably a good balance between the two. (Note: I'm saying this before I've even gotten around to doing it myself yet.)

This would propagate through @fedify to implementations (e.g., Hollo) where they would fail to lookup the @context for schema.org, which would prevent fetching Actor documents from GoToSocial 0.19.x

cc @gotosocial in case this is something you want to improve on your side

Fixed a rather gnarly bug in @fedify last night where schema.org's @context wasn't being resolved correctly because schema.org doesn't do content-neg and instead using link alternate headers to point to the JSON-LD context document. However, instead of using a fully qualified URL, it used a relative URL to the initial request, which caused Fedify to fail to fetch that context.

The main way to do that is to use a library that implements ActivityPub for you, like Fedify. https://fedify.dev/

As someone who works mainly in the front-end, ActivityPup (and related) always felt quite overwhelming and complicated to understand. I’ve been playing around with #Fedify for the past week or so and the documentation is so good it all just clicked for me! (I think so, at least :p)

Really excited to see what people build as ActivityPub becomes more approachable!

Due to the Internet Archive's unavailability, the https://purl.archive.org/socialweb/webfinger context is unable to be loaded, so a patch was made to preload (embed) the JSON-LD context. This patch was applied to #Fedify versions 0.15.3, 1.0.5, and 1.1.1, so please update if you are experiencing this issue.
