Fedify: an ActivityPub server framework

@fedify@hollo.social

We're thrilled to announce Fedify 1.8.1, a mega release made possible through the incredible efforts of contributors from South Korea's #OSSCA (Open Source Contribution Academy). This release marks a significant milestone in #Fedify's development, bringing major architectural changes, new packages, and numerous enhancements across the board.

Note: Version 1.8.0 was skipped due to a versioning error.

🎉 Major Milestone: Monorepo Architecture

Fedify has been restructured as a #monorepo, consolidating all packages into a single repository with unified versioning. This change streamlines development and ensures all packages are released together with consistent version numbers.

Consolidated Packages

All existing Fedify packages now live under one roof:

@fedify/fedify — Main library
@fedify/cli — CLI toolchain
@fedify/amqp — AMQP/RabbitMQ driver
@fedify/express — Express integration
@fedify/h3 — h3 framework integration
@fedify/postgres — PostgreSQL drivers
@fedify/redis — Redis drivers

🆕 New Packages

This release introduces four new packages to the Fedify ecosystem:

@fedify/elysia — Elysia integration for Bun-powered applications
@fedify/nestjs — NestJS integration for enterprise Node.js apps
@fedify/sqlite — SQLite driver compatible with Bun, Deno, and Node.js
@fedify/testing — Testing utilities with mock Federation and Context classes

@fedify/fedify

Custom Collection Dispatchers

A powerful new feature that allows you to create custom collections beyond the standard ActivityPub collections. This enables implementation of domain-specific collections while maintaining federation compatibility.

Contributors: ChanHaeng Lee [#310, #332]

Added comprehensive types and interfaces for custom collection handling
New methods on Federatable interface: setCollectionDispatcher() and setOrderedCollectionDispatcher()
Added getCollectionUri() method to the Context interface
Full support for paginated custom collections

Compare-and-Swap (CAS) Support for KV Stores

Key–value stores now optionally support CAS operations for atomic updates, enabling optimistic locking and preventing lost updates in concurrent environments.

Added optional KvStore.cas() method
Implemented in MemoryKvStore and DenoKvStore
Useful for implementing distributed locks and counters

Fediverse Handle Utilities

New utility functions make working with #fediverse handles more convenient.

Contributors: ChanHaeng Lee [#278]

parseFediverseHandle() — Parse handles into components
isFediverseHandle() — Validate handle format
toAcctUrl() — Convert handles to URLs
FediverseHandle interface for type safety

Enhanced HTTP Request APIs

Contributors: Lee ByeongJun [#248, #281], Hyunchae Kim [#51, #315]

Added LookupWebFingerOptions.maxRedirection option for controlling redirect behavior
APIs now support AbortSignal for request cancellation
New DocumentLoaderOptions interface
Added signal options to LookupObjectOptions, LookupWebFingerOptions, and DoubleKnockOptions

@fedify/cli

New Commands and Enhancements

The CLI has received significant improvements thanks to our OSSCA contributors:

`fedify webfinger` Command

Contributors: ChanHaeng Lee [#260, #278], KeunHyeong Park [#311, #328]

Look up WebFinger information for any fediverse resource:

Supports handles (@user@server) and URLs
--user-agent option for custom User-Agent headers
--allow-private-address for local testing
--max-redirection to control redirect following

`fedify nodeinfo` Command

Contributors: Hyeonseo Kim [#267, #331, #168, #282, #304]

Replaces the deprecated fedify node command with improved terminal rendering.

Enhanced `fedify lookup` Command

Contributors: Jiwon Kwon [#169, #348, #261, #321]

Terminal-specific image display for Kitty, WezTerm, Konsole, Warp, Wayst, st, and iTerm
-o/--output option to save results to files

Improved `fedify inbox` Command

Contributors: Hasang Cho [#262, #285], Jang Hanarae [#191, #342]

--actor-name and --actor-summary options for customizing temporary actors
Now displays object types contained in activities

`fedify init --dry-run`

Contributors: Lee ByeongJun [#263, #298]

Preview project initialization without creating files.

Better Terminal Support

Contributors: Cho Hasang [#257, #341]

Correctly handles color output based on TTY detection and NO_COLOR environment variable.

@fedify/elysia

Contributors: Hyeonseo Kim [#286, #339]

New Elysia integration brings Fedify to Bun-powered applications with a simple plugin interface:

import { Elysia } from "elysia";
import { fedify } from "@fedify/elysia";

const app = new Elysia()
  .use(fedify(federation, { /* options */ }))
  .listen(3000);

@fedify/nestjs

Contributors: Jaeyeol Lee [#269, #309]

Enterprise-ready NestJS integration with dependency injection support:

import { FedifyModule } from "@fedify/nestjs";

@Module({
  imports: [
    FedifyModule.forRoot({
      kv: new MemoryKvStore(),
      queue: new InProcessMessageQueue(),
      origin: "https://example.com",
    }),
  ],
})
export class AppModule {}

@fedify/sqlite

Contributors: An Subin [#274, #318]

SqliteKvStore implementation compatible across all major JavaScript runtimes:

import { SqliteKvStore } from "@fedify/sqlite";

const kv = new SqliteKvStore("./fedify.db");

@fedify/testing

Contributors: Lee ByeongJun [#197, #283]

Comprehensive testing utilities with mocking support for Fedify applications:

import { MockFederation, MockContext } from "@fedify/testing";

const mockFederation = new MockFederation();
const mockContext = new MockContext();

// Track sent activities with full metadata
// Support custom path registration
// Multiple activity type listeners
