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

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

A screenshot of a code editor showing a TypeScript class Person with a property get cat(): boolean | null. The accompanying comment explains that the property is "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'm learning ActivityPub for a larger project, but taking a moment to and code a minimal fediverse reader.

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

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

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

Hollo 0.3.0 released! is a single-user federated microblogging software which is -enabled and powered by .

The key changes of this release include:

  • Thanks to @joschi, Hollo now support local filesystem storage for media files. You can configure DRIVE_DISK=fs and FS_ASSET_PATH to store media files in the local filesystem. For users who've used S3, no further action is required—but, it's recommended to configure DRIVE_DISK=s3 as DRIVE_DISK will be required in the future releases.
  • Added support for Sentry. If you want to see error reports and instrumented traces in Sentry, please configure SENTRY_DSN.
  • Added pagination to the profile page.
  • Minor performance improvements and bug fixes due to upgrading Fedify to 1.3.0.

You can upgrade to Hollo 0.3.0 using the following ways:

Though we have OpenTelemetry Semantic Conventions 1.28.0, it does not yet define attributes related to the fediverse. So is taking the initiative to define semantic attributes related to the ActivityPub protocol and its related protocols. If you have any ideas, please leave a comment!

Semantic attributes for ActivityPub

The OpenTelemetry Semantic Conventions currently do not have a specification for ActivityPub.  However, Fedify provides a set of semantic attributes for ActivityPub.  The following table shows the semantic attributes for ActivityPub:

import { fedifyHook } from "@fedify/fedify/x/sveltekit";

const federation = createFederation<string>({

Starting with 1.3.0, you'll be able to use different message queues for incoming and outgoing activities!

https://unstable.fedify.dev/manual/mq#using-different-message-queues-for-different-tasks

Using different message queues for different tasks

This API is available since Fedify 1.3.0.

In some cases, you may want to use different message queues for different tasks, such as using a faster-but-less-persistent queue for outgoing activities and a slower-but-more-persistent queue for incoming activities. To achieve this, you can pass FederationQueueOptions to the CreateFederationOptions.queue option.

For example, the following code shows how to use a PostgresMessageQueue for the inbox and a RedisMessageQueue for the outbox:

const federation = createFederation<void>({
  queue: {
    inbox: new PostgresMessageQueue(
      postgres("postgresql://user:pass@localhost/db")
    ),
    outbox: new RedisMessageQueue(() => new Redis()),
  },
  // ... other options
});

Or, you can provide a message queue for only the inbox or outbox by omitting the other:

const federation = createFederation<void>({
  queue: {
    inbox: new PostgresMessageQueue(
      postgres("postgresql://user:pass@localhost/db")
    ),
    // outbox is not provided; outgoing activities will not be queued
  },
  // ... other options
});

Starting with 1.3.0, you can customize the User-Agent header for every HTTP request that Fedify makes.

https://unstable.fedify.dev/manual/federation#useragent

userAgent

This API is available since Fedify 1.3.0.

The options for making User-Agent header in the HTTP requests that Fedify makes. By default, it contains the name and version of the Fedify library, and the name and version of the JavaScript runtime, e.g.:

Fedify/1.3.0 (Deno/2.0.4)
Fedify/1.3.0 (Node.js/v22.10.0)
Fedify/1.3.0 (Bun/1.1.33)

You can customize the User-Agent header by providing options like software and url. For example, if you provide the following options:

{
  software: "MyApp/1.0.0",
  url: "https://myinstance.com/"
}

The User-Agent header will be like:

MyApp/1.0.0 (Fedify/1.3.0; Deno/2.0.4; +https://myinstance.com/)

Or, you can rather provide a custom User-Agent string directly instead of an object for options.

Have you heard of Val Town? Val Town is a kind of code pastebin + serverless function.

Actually, works just fine with Val Town. Here's a piece of ActivityPub software, implemented in about 170 lines of code, running on Val Town. Of course, it's built with Fedify!

Give it a follow @demo, and it will follow you back.

Continued my experiments with and yesterday and I think I’m confused.

I was trying to make an extension for an Object, and if I understand , the context property contains the definition of any extra property added. I see e.g. the activity streams ns resolves to a nice JSON LD that contains all the properties, but the mastodon one doesn’t resolve to anything? Is it not necessary?

Starting with the next release of , 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)!

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 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!

Latest update from @brewsterkahle (Oct 17, 5:58pm): blog.archive.org/2024/10/18/in

Last week, along with a DDOS attack and exposure of patron email addresses and encrypted passwords, the Internet Archive’s website javascript was defaced, leading us to bring the site down to access and improve our security. 

The stored data of the Internet Archive is safe and we are working on resuming services safely. This new reality requires heightened attention to cyber security and we are responding. We apologize for the impact of these library services being unavailable.

The Wayback Machine, Archive-It, scanning, and national library crawls have resumed, as well as email, blog, helpdesk, and social media communications.  Our team is working around the clock across time zones to bring other services back online. In coming days more services will resume, some starting in read-only mode as full restoration will take more time. 

We’re taking a cautious, deliberate approach to rebuild and strengthen our defenses. Our priority is ensuring the Internet Archive comes online stronger and more secure.

As a library community, we are seeing other cyber attacks—for instance the British Library, Seattle Public Library, Toronto Public Library, and now Calgary Public Library. We hope these attacks are not indicative of a trend.

For the latest updates, please check this blog and our official social media accounts: X/Twitter, Bluesky and Mastodon.

now has an driver! This means you can use as Fedify's message queue. To use it, first install the @fedify/amqp package, then set it up like below:

import { createFederation } from "@fedify/fedify";
import { AmqpMessageQueue } from "@fedify/amqp";
import { connect } from "amqplib";

const federation = createFederation({
  queue: new AmqpMessageQueue(await connect("amqp://localhost")),
  // ... other configurations
});

Oh, and we've also added results from AmqpMessageQueue to our benchmarks.

@thisismissem Here's the benchmark, and while it contains some questionable results, the overall conclusion is as following:

• Response times are much faster with queues than without.
• Overall throughput is better without queues.
• However, some queue setups can achieve throughput close to that of no queue.

This benchmark assumes communication within a single node, so the effect of queues may be greater in real-world networks.

Fedify: an ActivityPub server framework

@[email protected]

Fedify, an ActivityPub framework, has finally released its first stable version, 1.0.0! Here are key changes:

Deprecation of the term handle

From this version, the term handle across Fedify will only be used to refer to fediverse handles (e.g., @[email protected]). An actor's internal unique ID (e.g., b379dbdc-3b4f-4ef4-88c2-fc25632d1c22) is referred to as an identifier, and the WebFinger name (e.g., hongminhee) is referred to as a username.

The term handle in the API will be maintained for a while for backward compatibility, but deprecation warnings will be logged, and it is planned to be removed in the future.

For more details, please refer to the related documentation.

Linked Data Signatures

Linked Data Signatures is an outdated standard, but it's still relied upon by major fediverse implementations such as Mastodon.

In addition to HTTP Signatures and Object Integrity Proofs, Fedify now supports Linked Data Signatures from this version, thus supporting all types of signature methods used in the fediverse. This makes Fedify an ActivityPub implementation with the best interoperability.

However, Fedify users don't need to do anything special to use Linked Data Signatures. If an incoming activity has Linked Data Signatures, it automatically verifies the signature, and all outgoing activities will have signatures in three formats: HTTP Signatures, Linked Data Signatures, and Object Integrity Proofs.

For more details, please refer to the related documentation.

Activity forwarding

From this version, you can forward activities received in the inbox to other actors using the InboxContext.forwardActivity() method.

At first glance, you might think that you could just resend an activity received in the inbox using the Context.sendActivity() method. However, if you do this, the original signature is removed before the activity is delivered to the inbox, and when sending it, the signature of the forwarding actor is attached instead, causing the receiving side of the forwarded activity to not trust it.

On the other hand, when using the InboxContext.forwardActivity() method, the activity is forwarded with the original signature preserved, avoiding this problem. (Of course, the original activity itself must be signed with Linked Data Signatures or Object Integrity Proofs.)

For more details, please refer to the related documentation.

Sending Delete(Application) on fedify inbox termination

From this version, fedify inbox will send a Delete(Application) activity to all peer servers it encountered when terminated. This is typically an activity sent when deleting an account, which will help prevent residual data related to temporary actors from remaining on other servers.

PostgreSQL drivers

The @fedify/postgres package, which implements PostgreSQL drivers for the KvStore and MessageQueue interfaces, has been released alongside this version.

The PostgreSQL driver is a backend that can be sufficiently used in production, especially recommended for projects already using PostgreSQL.

Additionally, an option to select the PostgreSQL driver has been added to the fedify init command.

Celebrating Fedify 1.0.0

With the release of version 1.0.0, Fedify will now maintain API backward compatibility as much as possible. (Of course, in the long term, there may be a 2.0.0 that breaks backward compatibility.) This should be good news for those who have been hesitant to use Fedify because there hasn't been a stable version until now!

So, hoping that more services will support ActivityPub in the future, I conclude this post!

Starting with v1.0.0, the term handle throughout Fedify will only be used to refer to a fediverse handle (e.g., @[email protected]). An actor's internal unique ID (e.g., b379dbdc-3b4f-4ef4-88c2-fc25632d1c22) will be referred to as identifier and a WebFinger name (e.g., hongminhee) will be referred to as username. The term handle in the API will be retained for the time being for backwards compatibility, but a deprecation warning will be logged and will be deprecated in the future.

One of the benefits of is that you don't have to worry about whether a property of an Activity Vocabulary object has a URL or embeds an actual object. If you need an object, you can call the `getObject()` method (which will fetch a remote object if necessary). If you need a URI, you can access the `objectId` property.

The next version of will support (), which means that Fedify will be able to verify activities forwarded by from other servers.

In addition, activities sent with the Context.sendActivity() method will have Linked Data Signatures attached in addition to HTTP Signatures if any RSA-PKCS-v1.5 key pairs are present.

We were not motivated by implementing Linked Data Signatures, which is already an outdated standard, but we hope this change will lead to better compatibility and interoperability of Fedify apps!

I recently wrote a manual in Korean, and then translated it into English and Japanese. It's quite a long post, but it's relatively easy to accomplish with . Here's how I used it:

• Utilize projects to provide prior knowledge.
• Translate the table of contents first.
• Define a glossary.
• Translate chapter by chapter.

However, this method assumes you speak the target language—it's a way to reduce the labor of , not a way to become fluent in a language you don't know.

Working on @fedify's docs about … I hope someday drop the support for Linked Data Signatures… 😇

The combination of HTTP Signatures and Linked Data Signatures is the most widely supported way to sign activities in the fediverse, as of September 2024. Despite Linked Data Signatures is outdated and not recommended for new implementations, it is still widely used in the fediverse due to Mastodon and other major implementations' reliance on it.

However, for new implementations, you should consider using both Object Integrity Proofs and Linked Data Signatures for maximum compatibility and future-proofing.

Imagine what if every website implemented HTTP/TLS themselves. There would be so much fragmentation that we wouldn't see the we see today.

To me, that's what the looks like today. Mastodon, Pixelfed, etc. have their own implementations of , WebFinger, HTTP Signatures, etc. and each one behaves slightly differently, which leads to poor interoperability. Adoption of new standards is slow.

I received a request from @ghost today to add to @fedify for compatibility with , as Mastodon does not plan to implement Object Integrity Proofs (FEP-8b32) for the near future. 😩

However, Mastodon's implementation of LD Signatures does not even use valid JSON-LD properties (despite the name), so I'm not sure how to make it compatible with Mastodon since does JSON-LD processing. 🤔

The JSON-LD representation of a Create(Note) activity containing LD Signatures produced by Mastodon and its expanded form. The “signature” property and its child properties are not properly namespaced.

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

https://unstable.fedify.dev/manual/test#inspecting-activitypub-objects

Inspecting ActivityPub objects

BrowserPub

BrowserPub is a browser for debugging ActivityPub and the fediverse. You can punch in any ActivityPub discoverable web URL or fediverse handle, and it will discover and display the underlying ActivityPub.

For example:

• hollo.social/@fedify
• @hongminhee@fosstodon.org

If you want to know further details about BrowserPub, read the creator's Mastodon thread.

fedify lookup command

Fedify provides a CLI toolchain for testing and debugging. The fedify lookup command is a simple tool for looking up an ActivityPub object by its URL or fediverse handle.

Hollo를 소개합니다!

Hollo는 개인을 위한 연합형 마이크로블로그 소프트웨어입니다. FedifyBun으로 만들어졌으며, 프로토콜을 통해 다른 인스턴스 및 서비스와 교류할 수 있습니다.

Hollo의 특징은 한 사용자를 위해 설계된 전용 인스턴스라는 점입니다. 이를 통해 사용자는 자신만의 공간을 가지면서도 , 및 기타 ActivityPub 지원 서비스의 사용자들과 소통할 수 있습니다.

독자적인 웹 인터페이스는 없지만, Mastodon API와 호환되어 기존의 많은 Mastodon 클라이언트 앱을 사용하여 Hollo에 접근할 수 있습니다. 이로 인해 익숙한 인터페이스로 Hollo를 이용할 수 있습니다.

주요 기능으로는 게시물 작성·편집·삭제, 답글, 미디어 첨부, 투표, 좋아요, 북마크, 고정 등이 있습니다. 또한 프로필 편집, 팔로우/팔로워 관리, 리스트 생성 등도 가능합니다. 더불어 Markdown을 지원하여 게시물이나 프로필의 서식 설정을 쉽게 할 수 있습니다.

Hollo는 현재 개발 초기 단계에 있으며, 지속적으로 기능 추가와 개선이 이루어지고 있습니다. Bun을 사용함으로써 빠른 성능과 효율적인 개발이 이뤄지고 있답니다. 오픈 소스 프로젝트로 GitHub에 공개되어 있으며, 커뮤니티의 기여를 환영합니다.

개인 블로그와 소셜 미디어의 장점을 결합한 Hollo는 프라이버시를 중시하면서도 더 넓은 커뮤니티와의 연결을 원하는 사람들에게 적합한 플랫폼으로 거듭나고 있습니다.

Holloを紹介します!

Holloは、個人向けの連合型マイクロブログソフトウェアです。FedifyBunを基盤に構築され、ActivityPubプロトコルを通じて他のインスタンスやサービスと連携することができます。

Holloの特徴は、一人のユーザーのために設計された専用のインスタンスという点です。これにより、ユーザーは自分だけのスペースを持ちながら、Mastodon、Misskey、その他のActivityPub対応サービスのユーザーとも交流できます。

独自のウェブインターフェースを持たない代わりに、MastodonのAPIと互換性があるため、既存の多くのMastodonクライアントアプリを使用してHolloにアクセスできます。これにより、使い慣れたインターフェースでHolloを利用することができます。

主な機能には、投稿の作成・編集・削除、返信、メディア添付、投票、お気に入り、ブックマーク、ピン留めなどがあります。また、プロフィール編集、フォロー/フォロワー管理、リスト作成なども可能です。さらに、Markdownをサポートしているため、投稿やプロフィールの書式設定が容易に行えます。

Holloは現在開発の初期段階にあり、継続的に機能の追加や改善が行われています。Bunを使用することで、高速なパフォーマンスと効率的な開発が実現されています。オープンソースプロジェクトとして、GitHubで公開されており、コミュニティからの貢献を歓迎しています。

個人のブログとソーシャルメディアの利点を組み合わせたHolloは、プライバシーを重視しながら、より広いコミュニティとのつながりを求める人々に適したプラットフォームとなっています。

I've rewritten several times and in several languages. The first time it was written in , then , then C#, then back to TypeScript. (It was codenamed FediKit at the time of development.) I settled on TypeScript for the following reasons:

• It has a decent JSON-LD implementation.
• Lots of people use it. (I wanted Fedify to be widely used.)
• It's type-safe enough.

Even if I were to build Fedify again, I would choose TypeScript.

A quite fair comment on by .

—In your opinion, what is Fedify's weakest point?

Based on my review of the Fedify documentation, I think one potential weak point of Fedify is:

The learning curve and complexity involved in properly implementing all the components of a federated ActivityPub server.

While Fedify aims to simplify building ActivityPub servers, there are still many concepts and pieces that developers need to understand and implement correctly, including:

• Actor dispatchers
• Inbox listeners
• Collection dispatchers (outbox, followers, etc.)
• Key pair management
• Object dispatchers
• Access control
• Integration with web frameworks

The documentation is quite extensive, which is good, but also indicates there's a lot for developers to learn and configure properly. Even with Fedify abstracting away some of the low-level details, building a fully-featured and interoperable ActivityPub server requires understanding many moving parts.

Additionally, since Fedify provides flexibility in how these components are implemented, developers still need to make many decisions about data storage, business logic, etc. This flexibility is powerful but also puts more onus on developers to implement things correctly.

So while Fedify seems to be a very capable framework, the inherent complexity of building a federated server means there's still a significant learning curve and potential for implementation mistakes…

Introducing @fedify/express, a package that integrates Express, a popular web framework in Node.js, with Fedify. You can install it with the following command:

npm add @fedify/express

This package provides a middleware called integrateFederation() that allows you to integrate with :

import express from "express";
import { integrateFederation } from "@fedify/express";
import { federation } from "./federation";  // Your `Federation` instance

export const app = express();

app.set("trust proxy", true);

app.use(integrateFederation(federation, (req) => "context data goes here"));

I'm unsure whether to adopt an emerging JavaScript runtime like or for 's tutorial, or stick with traditional .js. 🤔

If I choose Bun/Deno, it comes with built-in support, hot reloading, and a fetch-style HTTP server, so I don't have to explain much about it, but I need to deal with installing Bun/Deno itself.

On the other hand, Node.js can be assumed to be already installed on the reader's system, but they will need to set up TypeScript, hot reloading, etc.

If you've created a new web framework, you can assume that your readers will have some knowledge of HTTP when you write tutorials for it. However, if you have created a new server framework, you should also explain ActivityPub itself in the tutorials for this framework.

튜토리얼에서 이렇게 에디터 뭐 쓰라고 이래라 저래라 하는 게 그다지 좋지 않다는 것은 잘 알고 있지만… 쓰는데 TypeScript LSP 안 켜두고 코딩하다가 자잘한 타입 에러를 못 보고 지나쳐서 오랫동안 트러블슈팅하는 사람들을 꽤 봤기 때문에 이렇게 Visual Studio Code 쓰라고 할 수밖에 없었다.

Visual Studio Code

Visual Studio Code가 여러분의 최애 에디터가 아닐 수 있습니다. 그렇지만, 이 튜토리얼을 따라하는 동안에는 Visual Studio Code를 써보실 것을 권합니다. 왜냐하면 우리는 TypeScript를 써야 하는데, Visual Studio Code는 현존하는 가장 간편하면서도 뛰어난 TypeScript IDE이기 때문입니다. 또한, 생성된 프로젝트 셋업에 이미 Visual Studio Code 설정이 갖춰져 있기 때문에 포매터나 린트 등과 씨름할 필요도 없습니다.

Visual Studio Code를 설치하였다면, 파일 → 폴더 열기… 메뉴를 눌러 작업 디렉터리를 불러오십시오.

만약 「이 리포지토리에 대한 권장되는 biomejs의 ‘Biome’ 확장을(를) 설치하시겠습니까?」라고 묻는 창이 뜨면 설치 버튼을 눌러 해당 확장을 설치하세요. 이 확장을 설치하면 들여쓰기나 띄어쓰기 같은 코드 스타일과 씨름할 필요 없이 자동으로 코드가 서식화 됩니다.

여러분이 충성스러운 Emacs 또는 Vim 사용자라면, 쓰던 여러분의 최애 에디터를 쓰는 것을 말리지 않겠습니다. 다만, 다음 몇 가지 설정은 짚고 넘어갈 것을 권합니다:

    TypeScript LSP

위 두 LSP 설정 여부에 따라 생산성의 차이가 크기 때문입니다.

Since v0.12.0, when verifying HTTP Signatures or Object Integrity Proofs, it will cache the public keys once fetched. It is okay even if a cached key becomes outdated because a verification failure due to a cached key will invalidate the cache and force a verification retry.

This feature is available for preview in v0.12.0-dev.307+235629d5 (JSR or npm).

I finally realized why so many frameworks come with an init/new command. Having that command makes for shorter tutorials!

I wrote a laravel package to add federation support to various internal @pixelfed projects like FediDB and PubKit

I might just polish this up and ship it, so laravel devs can add federation support with a few lines of code

offers robust logging capabilities through integration with LogTape. This feature allows you to easily debug and monitor your Fedify app!

To enable , simply install the @logtape/logtape package and configure it in your app's entry point:

import { configure, getConsoleSink } from "@logtape/logtape";

await configure({
  sinks: { console: getConsoleSink() },
  filters: {},
  loggers: [
    { category: "your-app", sinks: ["console"], level: "debug" },
    { category: "fedify",   sinks: ["console"], level: "info" },
  ],
});

Fedify uses hierarchical categories for fine-grained control over log output. Key categories include ["fedify", "federation", "http"] for HTTP requests/responses and ["fedify", "federation", "inbox"]/["fedify", "federation", "outbox"] for incoming/outgoing activities. (There are more categories.)

With integration, you gain valuable insights into your Fedify app's behavior, making troubleshooting and optimization much more straightforward!

now has a queue for incoming activities and they are automatically retried when they fail. The default retry strategy is good enough (exponential backoff + decorrelated jitter), and it's even fully customizable. Updated also the docs:

In the next version of , the type is introduced to let you fully customize the retry policy of the task queue for incoming and outgoing activities. Of course, you can also simply adjust the parameters of the built-in exponential backoff + decorrelated jitter policy.

outboxRetryPolicy

This API is available since Fedify 0.12.0.

The retry policy for sending activities to recipients' inboxes.

By default, this uses an exponential backoff strategy with a maximum of 10 attempts and a maximum delay of 12 hours.

You can fully customize the retry policy by providing a custom function that satisfies the RetryPolicy type. Or you can adjust the parameters of the createExponentialBackoffRetryPolicy() function, which is a default implementation of the retry policy.

Basic implementation of the inbox queue is complete and documentation is being worked on.

hollo.social/@fedify/0190687b-

Making inbox listeners non-blocking

This API is available since Fedify 0.12.0.

Usually, processes inside an inbox listener should be non-blocking because they may involve long-running tasks. Fortunately, you can easily turn inbox listeners into non-blocking by providing a queue option to createFederation() function. If it is not present, incoming activities are processed immediately and block the response to the sender until the processing is done.

While the queue option is not mandatory, it is highly recommended to use it in production environments to prevent the server from being overwhelmed by incoming activities.

Note: Activities with invalid signatures/proofs are silently ignored and not queued.

When there is no queue, if the process fails, the inbox can just respond with a 500 server error and the sender will resend it.

But with a queue, by the time the inbox responds, it doesn't know if the process will fail because it hasn't run yet. So the sender won't retry whether it fails or not.

So, should it have its own retry logic when there is a queue?
