Fedify: ActivityPub server framework
@fedify@hollo.social

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.

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

https://www.val.town/v/minhee/FedifyOnValTown

@minhee/FedifyOnValTown

Fedify on Val Town This is a single file implementation of ActivityPub using Fedify on Val Town . If you follow @demo@minhee-fedifyonvaltown.web.val.run on your fediverse account, it will follow you back. Thanks to Fedify & Val Town, it only consists of a single TypeScript file with about 170 lines.

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 });

@Montreal_Weather But if you plan to have this many bots, I would encourage you to not rely on Mastodon for those bots, but implement your own (very simple) ActivityPub software, it will be much easier for you.
For example see shkspr.mobi/blog/2024/02/a-tin, or fedify.dev for NodeJS

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.
