Fedify: an ActivityPub server framework

@[email protected]

Introducing #BotKit: A #TypeScript framework for creating truly standalone #ActivityPub bots!

Unlike traditional Mastodon bots, BotKit lets you build fully independent #fediverse bots that aren't constrained by platform limits. Create your entire bot in a single TypeScript file using our simple, expressive API.

Currently #Deno-only, with Node.js & Bun support planned. Built on the robust #Fedify foundation.

https://botkit.fedify.dev/

import { createBot, InProcessMessageQueue, MemoryKvStore, mention, text, } from "@fedify/botkit"; // Create a bot instance: const bot = createBot<void>({ // The bot will have fediverse handle "@greetbot@mydomain": username: "greetbot", // Set the display name: name: "Greet Bot", // Set the profile icon (avatar): icon: new URL("https://mydomain/icon.png"), // Set the bio: summary: text`Hi, there! I'm a simple fediverse bot created by ${ mention("@[email protected]")}.`, // Store data in memory (for development): kv: new MemoryKvStore(), // Use in-process message queue (for development): queue: new InProcessMessageQueue(), }); // A bot can respond to a mention: bot.onMention = async (session, message) => { await message.reply(text`Hi, ${message.actor}!`); }; // Or, a bot also can actively publish a post: const session = bot.getSession("https://mydomain/"); setInterval(async () => { await session.publish(text`Hi, forks! It's an hourly greeting.`); }, 1000 * 60 * 60); export default bot;

Okay, I finished the groundwork of #BotKit today. It's #Deno-only yet though. It's on GitHub!

Even though it's built on #Fedify, its API looks completely different from Fedify's one. I intended to make it resembles more Discord/Telegram bot frameworks than Fedify. I think it's close to my intention.

The last "big" code thing I need to get done before the alpha test of my current @fedify project is the task queue - make sure routine data updates happen, consider individual importance and urgency, respect external API rate limits, etc.

But that's super intimidating so I'm currently procrastinating by making it a cute lil home page instead. 🙃

Now that I got some fond memories of #typescript (read: Stockholm Syndrome), I sort of want to build stuff with #fedify. 😅

Though what I *really* want is an option like it for #ElixirLang. Maybe a project for the new year. 🤔

Not like we don't have #Akkoma, #Bonfire, #Pleroma, and #Mobilizon as examples of what could be a standard library. 😄

Hollo

@[email protected]

Hollo 0.4.0 released! #Hollo is a single-user federated microblogging software which is #ActivityPub-enabled and powered by #Fedify.

The key changes of this release include:

Hollo is now powered by Node.js 23+ instead of Bun for more efficient memory usage.
Added an experimental feature flag TIMELINE_INBOXES to store all posts visible to your timeline in the database, rather than filtering them in real-time as they are displayed. This is useful for relatively larger instances with many incoming posts, but as of now it may have several bugs. It is expected to be the default behavior in the future after it is stabilized.
Now you can import and export your data from the administration dashboard in CSV format: follows, lists, accounts you muted, accounts you blocked, and bookmarks.
You can now make your profile discoverable.
The profile page now shows an account's cover image if it has one.
Many bug fixes.

For the details, see also the full changelog.

You can upgrade to Hollo 0.4.0 using the following ways:

To Railway users: Just redeploy the Hollo service!
To Docker users: Switch your Hollo image to ghcr.io/dahlia/hollo:0.4.0 or simply latest!
To manual installers:
1. Install Node.js 23 or higher.
2. Install pnpm.
3. Fetch the stable branch and switch over to it.
4. Run pnpm install.
5. Run pnpm run prod to start the Hollo server.

Hollo

@[email protected]

#Hollo is currently testing #Node.js instead of #Bun. (In fact, the hollo.social server is already running on Node.js!) If this test is successful, starting with the next release, Hollo will be powered by Node.js instead of Bun.

The main reason for switching to Node.js is to optimize memory usage. As you can see in the graph image below, Node.js uses significantly less memory than Bun. With this switch, Hollo is expected to be even more lightweight than before!

Are you interested in trying out the Node.js version of Hollo early? Try to pull ghcr.io/dahlia/hollo:0.4.0-dev.290!

Hollo's memory usage graph. When I was running on Bun, it used about 4GB of memory, but after switching to Node.js, it uses about 0.5GB of memory.

I'm currently brainstorming a framework for creating fediverse bots called #BotKit, based on #Fedify. It's less flexible than Fedify, but the goal is to make it possible to create simple fediverse bots with much less code. What do you think?

I'd like to translate #Fedify's docs into multiple languages, at least into Korean and Japanese, which are languages I speak, but I'm not sure how useful it would be compared to the cost. Fedify's docs are already pretty extensive, so translating them would be difficult, plus the cost of updating them would be quite high. 🤔

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:

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

https://fediverse.hayes.software

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

A screenshot showing 2 browser windows, one in landscape format, one in portrait format, to represent desktop and mobile viewports. The design is very yellow and sepia-ish showing a toot and an image next to it. A lot of brush and marker strokes are incorporated into the design. Otherwise the design is minimal.

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!

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."

#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 :blobcatfingergun: .

A design mockup of a minimalistic "Fediverse Reader" app created in Inkscape, showcasing layouts for desktop and mobile screens. The designs include variations of a homepage and post view with text and images. The interface uses light yellow tones and emphasizes simplicity with modern, clean lines.

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.

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.

Though we have OpenTelemetry Semantic Conventions 1.28.0, it does not yet define attributes related to the fediverse. So #Fedify 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!

We are going to add instrumentation support for #OpenTelemetry to #Fedify. What kind of spans or events would you like to be instrumented?

Starting with #Fedify 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

Fedify: an ActivityPub server framework

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

Actually, #Fedify 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.

Curious to see how it was implemented? Check out the source code!

Fedify: an ActivityPub server framework

@[email protected]

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:

Introducing #Hollo. Hollo is an #ActivityPub-enabled single-user microblogging software. Although it's for a single user, it also supports creating and running multiple accounts for different topics.

It's headless, meaning you can use existing #Mastodon client apps instead, with its Mastodon-compatible APIs. It has most feature parity with Mastodon. Two big differences with Mastodon is that you can use #Markdown in the content of your posts and you can quote another post.

Oh, and Hollo is built using #Bun and #Fedify.
