Fedify: ActivityPub server framework

@fedify@hollo.social

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:

Fedify: ActivityPub server framework

@fedify@hollo.social

Exciting news for #Fedify developers! We've just landed a major milestone for Fedify 2.0—the #CLI now runs natively on #Node.js and #Bun, not just #Deno (#456). If you install @fedify/cli@2.0.0-dev.1761 from npm, you'll get actual JavaScript that executes directly in your runtime, no more pre-compiled binaries from deno compile. This is part of our broader transition to Optique, a new cross-runtime CLI framework we've developed specifically for Fedify's needs (#374).

This change means a more natural development experience regardless of your #JavaScript runtime preference. Node.js developers can now run the CLI tools directly through their familiar ecosystem, and the same goes for Bun users. While Fedify 2.0 isn't released yet, we're excited to share this progress with the community—feel free to try out the dev version and let us know how it works for you!

A grumpy ItSec guy walks through the office when he overhears an exchange of words.

devops0: Two containers went rogue last night and starved the whole host.
devops1: What are we supposed to do?

ItSec (walking by): Set limits. It's not rocket science. Docker exposes cgroup controls for CPU, memory, I/O and PIDs. Use them.

The point is: availability is part of security too. Linux control groups allow you to cap, isolate and observe resource usage, which is exactly how Docker enforces container limits for CPU, memory, block I/O and process counts [1]. Let's make it tangible with a small lab. We'll spin a container, install stress-ng, and watch limits in action.

# On the Docker host
docker run -itd --name ubuntu-limits ubuntu:22.04
docker exec -it ubuntu-limits bash

# Inside the container
apt update && apt install -y stress-ng
stress-ng --version

Check how many cores you see, then drive them.

# Inside the container
nproc

# For my host nproc returns 4
stress-ng --cpu 4 --cpu-load 100 --timeout 30s

In another terminal, watch usage from the host.

docker stats

Now clamp CPU for the running container and see the throttle take effect.

docker update ubuntu-limits --cpus=1
docker stats

The --cpus flag is a wrapper over the Linux CFS period/quota; --cpus=1 caps the container at roughly one core worth of time on a multi‑core host.

Memory limits are similar. First tighten RAM and swap, then try to over‑allocate in the container.

# On the host
docker update ubuntu-limits --memory=128m --memory-swap=256m
docker stats

# Inside the container: stays under the cap
stress-ng --vm 1 --vm-bytes 100M --timeout 30s --vm-keep

# Inside the container: tries to exceed; you may see reclaim/pressure instead of success
stress-ng --vm 1 --vm-bytes 300M --timeout 30s --vm-keep

A few memory details matter. --memory is the hard ceiling; --memory-swap controls total RAM+swap available. Setting swap equal to memory disables swap for that container; leaving it unset often allows swap equal to the memory limit; setting -1 allows unlimited swap up to what the host provides.

docker run -it --rm \
  --name demo \
  --cpus=1 \
  --memory=256m \
  --memory-swap=256m \
  --pids-limit=25 \
  ubuntu:22.04 bash

For plain docker compose (non‑Swarm), set service‑level attributes. The Compose Services reference explicitly supports cpus, mem_limit, memswap_limit and pids_limit on services [2].

services:
  api:
    image: ubuntu:22.04
    command: ["sleep","infinity"]
    cpus: "1"              # 50% of one CPU equivalent
    mem_limit: "256m"      # hard RAM limit
    memswap_limit: "256m"  # RAM+swap; equal to mem_limit disables swap
    pids_limit: 50         # max processes inside the container

#NPM from #Node.js ended up in the hands of Microsoft.

#RubyGems from #Ruby ended up in the hands of a nazi libertarian.

It feels like #OSS and #FOSS are being attacked on a daily basis.

Do anyone have information regarding #PyPi from #Python, is it also compromised? As far as I know, PyPi stopped working with pip search ("Use the browser") and the website needs JS to function (because it uses some PoW browser checking), so using Lynx or elinks as a sysadmin on a terminal-only machine in order to search for Python packages have been a no-no. Wonder how much it's due to similar phenomenon going on with Ruby and Node.js ecosystems.

洪民憙 (Hong Minhee)

@hongminhee@hackers.pub

We're excited to announce Optique 0.4.0, which brings significant improvements to help text organization, enhanced documentation capabilities, and introduces comprehensive Temporal API support.

Optique is a type-safe combinatorial CLI parser for TypeScript that makes building command-line interfaces intuitive and maintainable. This release focuses on making your CLI applications more user-friendly and maintainable.

Better help text organization

One of the most visible improvements in Optique 0.4.0 is the enhanced help text organization. You can now label and group your options more effectively, making complex CLIs much more approachable for users.

Labeled merge groups

The merge() combinator now accepts an optional label parameter, solving a common pain point where developers had to choose between clean code structure and organized help output:

// Before: unlabeled merged options appeared scattered
const config = merge(connectionOptions, performanceOptions);

// Now: group related options under a clear section
const config = merge(
  "Server Configuration",  // New label parameter
  connectionOptions,
  performanceOptions
);

This simple addition makes a huge difference in help text readability, especially for CLIs with many options spread across multiple reusable modules.

The resulting help output clearly organizes options under the Server Configuration section:

Demo app showcasing labeled merge groups
Usage: demo-merge.ts --host STRING --port INTEGER --timeout INTEGER --retries
       INTEGER

Server Configuration:
  --host STRING               Server hostname or IP address
  --port INTEGER              Port number for the connection
  --timeout INTEGER           Connection timeout in seconds
  --retries INTEGER           Number of retry attempts

The new `group()` combinator

For cases where merge() doesn't apply, the new group() combinator lets you wrap any parser with a documentation label:

// Group mutually exclusive options under a clear section
const outputFormat = group(
  "Output Format",
  or(
    map(flag("--json"), () => "json"),
    map(flag("--yaml"), () => "yaml"),
    map(flag("--xml"), () => "xml"),
  )
);

This is particularly useful for organizing mutually exclusive flags, multiple inputs, or any parser that doesn't natively support labeling. The resulting help text becomes much more scannable and user-friendly.

Here's how the grouped output format options appear in the help text:

Demo app showcasing group combinator
Usage: demo-group.ts --json
       demo-group.ts --yaml
       demo-group.ts --xml

Output Format:
  --json                      Output in JSON format
  --yaml                      Output in YAML format
  --xml                       Output in XML format

Rich documentation support

Optique 0.4.0 introduces comprehensive documentation fields that can be added directly through the run() function, eliminating the need to modify parser definitions for documentation purposes.

Brief descriptions, detailed explanations, and footers

Both @optique/core/facade and @optique/run now support brief, description, and footer options through the run() function:

import { run } from "@optique/run";
import { message } from "@optique/core/message";

const result = run(parser, {
  brief: message`A powerful data processing tool`,
  description: message`This tool provides comprehensive data processing capabilities with support for multiple formats and transformations. It can handle JSON, YAML, and CSV files with automatic format detection.`,
  footer: message`Examples:
  myapp process data.json --format yaml
  myapp validate config.toml --strict

For more information, visit https://example.com/docs`,
  help: "option"
});

These documentation fields appear in both help output and error messages (when configured), providing consistent context throughout your CLI's user experience.

The complete help output demonstrates the rich documentation features with brief description, detailed explanation, option descriptions, default values, and footer information:

A powerful data processing tool
Usage: demo-rich-docs.ts [--port INTEGER] [--format STRING] --verbose STRING

This tool provides comprehensive data processing capabilities with support for
multiple formats and transformations. It can handle JSON, YAML, and CSV files
with automatic format detection.

  --port INTEGER              Server port number [3000]
  --format STRING             Output format [json]
  --verbose STRING            Verbosity level

Examples:
  myapp process data.json --format yaml
  myapp validate config.toml --strict

For more information, visit https://example.com/docs

These documentation fields appear in both help output and error messages (when configured), providing consistent context throughout your CLI's user experience.

Display default values

A frequently requested feature is now available: showing default values directly in help text. Enable this with the new showDefault option when using withDefault():

const parser = object({
  port: withDefault(
    option("--port", integer(), { description: message`Server port number` }),
    3000,
  ),
  format: withDefault(
    option("--format", string(), { description: message`Output format` }),
    "json",
  ),
});

run(parser, { showDefault: true });

// Or with custom formatting:
run(parser, {
  showDefault: {
    prefix: " (default: ",
    suffix: ")"
  }  // Shows: --port (default: 3000)
});

Default values are automatically dimmed when colors are enabled, making them visually distinct while remaining readable.

The help output shows default values clearly marked next to each option:

Usage: demo-defaults.ts [--port INTEGER] [--format STRING]

  --port INTEGER              Server port number [3000]
  --format STRING             Output format [json]

Temporal API support

Optique 0.4.0 introduces a new package, @optique/temporal, providing comprehensive support for the modern Temporal API. This brings type-safe parsing for dates, times, durations, and time zones:

import { instant, duration, zonedDateTime } from "@optique/temporal";
import { option } from "@optique/core/parser";

const parser = object({
  // Parse ISO 8601 timestamps
  timestamp: option("--at", instant()),

  // Parse durations like "PT30M" or "P1DT2H"
  timeout: option("--timeout", duration()),

  // Parse zoned datetime with timezone info
  meeting: option("--meeting", zonedDateTime()),
});

The temporal parsers return native Temporal objects with full functionality:

const result = parse(timestampArg, ["2023-12-25T10:30:00Z"]);
if (result.success) {
  const instant = result.value;
  console.log(`UTC: ${instant.toString()}`);
  console.log(`Seoul: ${instant.toZonedDateTimeISO("Asia/Seoul")}`);
}

Install the new package with:

npm add @optique/temporal

Improved type inference

The merge() combinator now supports up to 10 parsers (previously 5), and the tuple() parser has improved type inference using TypeScript's const type parameter. These enhancements enable more complex CLI structures while maintaining perfect type safety.

Breaking changes

While we've maintained backward compatibility for most APIs, there are a few changes to be aware of:

The Parser.getDocFragments() method now uses DocState<TState> instead of direct state values (only affects custom parser implementations)
The merge() combinator now enforces stricter type constraints at compile time, rejecting non-object-producing parsers

We're excited to announce Optique 0.4.0, which brings significant improvements to help text organization, enhanced documentation capabilities, and introduces comprehensive Temporal API support.

Better help text organization

Labeled merge groups

The merge() combinator now accepts an optional label parameter, solving a common pain point where developers had to choose between clean code structure and organized help output:

// Before: unlabeled merged options appeared scattered
const config = merge(connectionOptions, performanceOptions);

// Now: group related options under a clear section
const config = merge(
  "Server Configuration",  // New label parameter
  connectionOptions,
  performanceOptions
);

This simple addition makes a huge difference in help text readability, especially for CLIs with many options spread across multiple reusable modules.

The resulting help output clearly organizes options under the Server Configuration section:

Demo app showcasing labeled merge groups
Usage: demo-merge.ts --host STRING --port INTEGER --timeout INTEGER --retries
       INTEGER

Server Configuration:
  --host STRING               Server hostname or IP address
  --port INTEGER              Port number for the connection
  --timeout INTEGER           Connection timeout in seconds
  --retries INTEGER           Number of retry attempts

The new `group()` combinator

For cases where merge() doesn't apply, the new group() combinator lets you wrap any parser with a documentation label:

// Group mutually exclusive options under a clear section
const outputFormat = group(
  "Output Format",
  or(
    map(flag("--json"), () => "json"),
    map(flag("--yaml"), () => "yaml"),
    map(flag("--xml"), () => "xml"),
  )
);

Here's how the grouped output format options appear in the help text:

Demo app showcasing group combinator
Usage: demo-group.ts --json
       demo-group.ts --yaml
       demo-group.ts --xml

Output Format:
  --json                      Output in JSON format
  --yaml                      Output in YAML format
  --xml                       Output in XML format

Rich documentation support

Optique 0.4.0 introduces comprehensive documentation fields that can be added directly through the run() function, eliminating the need to modify parser definitions for documentation purposes.

Brief descriptions, detailed explanations, and footers

Both @optique/core/facade and @optique/run now support brief, description, and footer options through the run() function:

import { run } from "@optique/run";
import { message } from "@optique/core/message";

const result = run(parser, {
  brief: message`A powerful data processing tool`,
  description: message`This tool provides comprehensive data processing capabilities with support for multiple formats and transformations. It can handle JSON, YAML, and CSV files with automatic format detection.`,
  footer: message`Examples:
  myapp process data.json --format yaml
  myapp validate config.toml --strict

For more information, visit https://example.com/docs`,
  help: "option"
});

These documentation fields appear in both help output and error messages (when configured), providing consistent context throughout your CLI's user experience.

The complete help output demonstrates the rich documentation features with brief description, detailed explanation, option descriptions, default values, and footer information:

A powerful data processing tool
Usage: demo-rich-docs.ts [--port INTEGER] [--format STRING] --verbose STRING

This tool provides comprehensive data processing capabilities with support for
multiple formats and transformations. It can handle JSON, YAML, and CSV files
with automatic format detection.

  --port INTEGER              Server port number [3000]
  --format STRING             Output format [json]
  --verbose STRING            Verbosity level

Examples:
  myapp process data.json --format yaml
  myapp validate config.toml --strict

For more information, visit https://example.com/docs

These documentation fields appear in both help output and error messages (when configured), providing consistent context throughout your CLI's user experience.

Display default values

A frequently requested feature is now available: showing default values directly in help text. Enable this with the new showDefault option when using withDefault():

const parser = object({
  port: withDefault(
    option("--port", integer(), { description: message`Server port number` }),
    3000,
  ),
  format: withDefault(
    option("--format", string(), { description: message`Output format` }),
    "json",
  ),
});

run(parser, { showDefault: true });

// Or with custom formatting:
run(parser, {
  showDefault: {
    prefix: " (default: ",
    suffix: ")"
  }  // Shows: --port (default: 3000)
});

Default values are automatically dimmed when colors are enabled, making them visually distinct while remaining readable.

The help output shows default values clearly marked next to each option:

Usage: demo-defaults.ts [--port INTEGER] [--format STRING]

  --port INTEGER              Server port number [3000]
  --format STRING             Output format [json]

Temporal API support

Optique 0.4.0 introduces a new package, @optique/temporal, providing comprehensive support for the modern Temporal API. This brings type-safe parsing for dates, times, durations, and time zones:

import { instant, duration, zonedDateTime } from "@optique/temporal";
import { option } from "@optique/core/parser";

const parser = object({
  // Parse ISO 8601 timestamps
  timestamp: option("--at", instant()),

  // Parse durations like "PT30M" or "P1DT2H"
  timeout: option("--timeout", duration()),

  // Parse zoned datetime with timezone info
  meeting: option("--meeting", zonedDateTime()),
});

The temporal parsers return native Temporal objects with full functionality:

const result = parse(timestampArg, ["2023-12-25T10:30:00Z"]);
if (result.success) {
  const instant = result.value;
  console.log(`UTC: ${instant.toString()}`);
  console.log(`Seoul: ${instant.toZonedDateTimeISO("Asia/Seoul")}`);
}

Install the new package with:

npm add @optique/temporal

Improved type inference

Breaking changes

While we've maintained backward compatibility for most APIs, there are a few changes to be aware of:

The Parser.getDocFragments() method now uses DocState<TState> instead of direct state values (only affects custom parser implementations)
The merge() combinator now enforces stricter type constraints at compile time, rejecting non-object-producing parsers

BotKit by Fedify

@botkit@hollo.social

We're excited to announce the release of BotKit 0.3.0! This release marks a significant milestone as #BotKit now supports #Node.js alongside #Deno, making it accessible to a wider audience. The minimum required Node.js version is 22.0.0. This dual-runtime support means you can now choose your preferred #JavaScript runtime while building #ActivityPub #bots with the same powerful BotKit APIs.

One of the most requested features has landed: poll support! You can now create interactive polls in your #bot messages, allowing followers to vote on questions with single or multiple-choice options. Polls are represented as ActivityPub Question objects with proper expiration times, and your bot can react to votes through the new onVote event handler. This feature enhances engagement possibilities and brings BotKit to feature parity with major #fediverse platforms like Mastodon and Misskey.

// Create a poll with multiple choices
await session.publish(text`What's your favorite programming language?`, {
  class: Question,
  poll: {
    multiple: true,  // Allow multiple selections
    options: ["JavaScript", "TypeScript", "Python", "Rust"],
    endTime: Temporal.Now.instant().add({ hours: 24 }),
  },
});

// Handle votes
bot.onVote = async (session, vote) => {
  console.log(`${vote.actor} voted for "${vote.option}"`);
};

The web frontend has been enhanced with a new followers page, thanks to the contribution from Hyeonseo Kim (@gaebalgom)! The /followers route now displays a paginated list of your bot's followers, and the follower count on the main profile page is now clickable, providing better visibility into your bot's audience. This improvement makes the web interface more complete and user-friendly.

For developers looking for alternative storage backends, we've introduced the SqliteRepository through the new @fedify/botkit-sqlite package. This provides a production-ready SQLite-based storage solution with ACID compliance, write-ahead logging (WAL) for optimal performance, and proper indexing. Additionally, the new @fedify/botkit/repository module offers MemoryCachedRepository for adding an in-memory cache layer on top of any repository implementation, improving read performance for frequently accessed data.

This release also includes an important security update: we've upgraded to #Fedify 1.8.8, ensuring your bots stay secure and compatible with the latest ActivityPub standards. The repository pattern has been expanded with new interfaces and types like RepositoryGetMessagesOptions, RepositoryGetFollowersOptions, and proper support for polls storage through the KvStoreRepositoryPrefixes.polls option, providing more flexibility for custom implementations.

new release of #Fedialgo, the customizable timeline algorithm / filtering system for your Mastodon feed, counts the number of times each hashtag appears in your timeline even if people don't use a "#" character to give you a better sense of what people are talking about in the Fediverse.

there's a little bit of art vs. science here because some strings are disqualified from this kind of counting (e.g. a word like "the" should not be counted even if some maniac decided to make it a hashtag) so let me know if you see any weirdly high counts.

The FediAlgo hashtag filter section now highlights any hashtags you've posted about recently.

Interestingly the most I've used the app the more I've found feed filtering gets a ton of mileage for me. It's a huge change of pace to be able to instantly flip between whatever people are talking about on the Fediverse. Not really something you can do on any other social media platform I'm aware of.

1. Configuration presets (so you can easily put discussions or trending toots at the top of your #timeline without fiddling with the individual settings)

2. A "What's Trending" section that will show you the top trending hashtags, links, and posts scraped from 30 or so of the most popular Mastodon servers

All the old features like filtering for particular languages / hashtags / users or a minimum number of replies / boosts / etc. are still there.

* Usable demo: https://michelcrypt4d4mus.github.io/fedialgo_demo_app_foryoufeed/
* Code: https://github.com/michelcrypt4d4mus/fedialgo_demo_app_foryoufeed
* Library: https://github.com/michelcrypt4d4mus/fedialgo

Another library frustration: is there a standard Make-like task runner tool for #Node? 10 years ago Grunt and Gulp were standard for this, but they're horribly out of date now and not compatible with ES6 imports. There are tools in other languages, like go-task, but I can't find anything similar in JS.

Fedify: ActivityPub server framework

@fedify@hollo.social

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:

I'm reading that it's possible to use #nextjs with #bun instead of #node? 😳

I've worked with dates and times in several programming languages, and I have to say that the best is easily PHP (since the big refactor in, what was it, 5.6?).

The worst is easily Javascript.

@Sh4d0w_H34rt @bunbloc Oh, sorry, was not clear. I was thinking of a #mastodon instance solely over #reticulum using #LXMF and not via any other protocol, to make it a bit special and to provide superb chat rooms or group chats and fill that current gap. #reticulum allows for images of course. Would work very well indeed perhaps. Was wondering how much code would need changing to #mastodon to port it to a #reticulum #node #nomad server ...
