Fedify: an ActivityPub server framework

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:

Hello, #fediverse! It's the official fedi account of the Fedify, an #ActivityPub server framework!

@Rumisan 私はChatGPTではなくClaudeを使っていますが、Claudeのプロジェクト機能を活用して、プロジェクトにFedifyのドキュメントを全て入れて質問しています。実際にチュートリアルやサンプルコードをそうやって生成した事も有ります！

Since #Fedify 1.4.0, our next release, the fedify lookup command will have the -t/--traverse option! It takes a URL of the collection, and traverse its items from the beginning to the end. Here's a demo:

とりあえず、最近fedifyでDevContainer経由で建てたローカルのリレーサーバとMastodonでリレーの処理が確認できそうなことがわかったんで動作確認手順まとめてます

そういやリレーサーバの疎通確認、fedify tunnel使ってできたよ

@hongminhee
Yay!

fedify 튜토리얼 읽어봐야지..

I made a thing. You can put a Mastodon post URL in the search box and it will show the post.

I was learning #Fedify and I wanted to make a minimal Next.js example of a "read-only" app that was for consuming the Fediverse and didn't mess with interactions. It started as a boilerplate to benefit other devs, but the act of making it forced me to learn a lot more about Fedify and ActivityPub.
#WebDev #Demo

@chris_hayes Yes, it corresponds to the misskey:isCat property! According to the docs:

Used on actors to indicate that they in some way identify as a cat, expressed as a boolean value. If this property is set to true, displaying the actor or their notes will have some special effects attached in some clients.

I was looking at the properties on the Person #ActivityPub object implemented by #fedify, and wasn't expecting this one, haha!

I'm presuming this is #Misskey related? The quirks of having to implement many different versions of a spec!

#WIP - I'm learning ActivityPub for a larger project, but taking a moment to #design and code a minimal fediverse reader.

I found it tricky learning to make a read-only app with #Fedify, so wanted to make this example Next.js project available. Got a little carried away with the design.

Mockup in #Inkscape, it's a better prototyping tool than one might expect.

Hopefully @tamami doesn't mind me using her nice post in my mockup .

The #Fedify repository has reached 600 stars! Thank you everyone!

Here's the detailed release note of Fedify 1.3.0!

https://dev.to/hongminhee/fedify-130-opentelemetry-support-enhanced-message-queue-42gk

ActivityPubサーバーフレームワークのFedifyの1.3.0バージョンがリリースされました。主な変更点は以下の通りです。

• OpenTelemetry の計装のスパンが追加されました。殆どの場合、アプリケーションにOpenTelemetry SDKが設定されていれば、自動的に計装されます。
• 今回のバージョンから、受信アクティビティと送信アクティビティに対して異なるMessageQueueを設定する事が出来る様に成りました。
• Activityを手動でインボックスリスナーにルーティングする事が出来る様に成りました。
• Context.sendActivity()とforwardActivity()メソッドは、タスクをキューに入れる事に失敗した場合、エラーを出す様に成りました。
• @robin_maki さんのおかげでSvelteKitと連携する為に@fedify/fedify/x/sveltekitモジュールが追加されました。
• 正しいUser-Agentヘッダ（例えば、`User-Agent: Fedify/1.3.0 (Deno/2.1.2)`）を含めてHTTPリクエストを送る様に成りました。

詳細は変更ログをご覧ください！

The version 1.3.0 of #Fedify, an #ActivityPub server framework, released! The key changes include:

• Instrumented spans for OpenTelemetry are added. In most cases, it's automatically enabled if your application configured OpenTelemetry SDK.
• Since Fedify 1.3.0, you can configure different MessageQueues for incoming and outgoing activities.
• Fedify now allows you to manually route an Activity to the corresponding inbox listener. It is useful for invoking an inbox listener for an Activity enclosed by another Activity.
• Context.sendActivity() and InboxContext.forwardActivity() methods now reject when they fail to enqueue the task.
• Thanks to @robin_maki, @fedify/fedify/x/sveltekit module is added for integrating with SvelteKit hook.
• Fedify now makes HTTP requests with the proper User-Agent header, e.g., User-Agent: Fedify/1.3.0 (Deno/2.1.2).

For details, see the full changelog as well!

Fedify 1.3.0 is available at JSR and npm.

I would like to translate #Fedify's docs into Korean and Japanese, the languages I can speak, but the amount of the docs is quite much, so I can't even think of doing it. The maintenance costs for updating the docs also cannot be ignored.

#Fedify's @opentelemetry instrumentation works like a charm with @getsentry!

Many more spans were added today!

@thisismissem Sure thing! We're adding more spans in next few days, including document loaders!
