Absolutely outstanding progress! definitely deserves a great deal of recognition for making this possible. 😎

Feeling like we now have tooling in place to fediverse all things. πŸ˜…

looks like there will be lighter-weight alternatives to mastodon, thanks to @fedify β€” maybe I’ll hack together a simple one? πŸ™ƒ

@fedify users of Fedify still need to keep potential for SSRF in mind when requesting any URLs in Activities/Objects not through these APIs, e.g., when downloading media from a remote server for caching

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:

unstable.fedify.dev/manual/inb

You can give it a try by installing 0.12.0-dev.265+cb851932, the latest unstable release:

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.

has always been queuing outgoing activities, but not incoming activities. Thanks to @ghost's sponsorship, we are now implementing queues for incoming activities!

has supported optional queuing for outgoing activities, with two built-in message queue backends: InProcessMessageQueue, which is suitable for development, and DenoKvMessageQueue, which is only available in Deno.

Fedify has also had two built-in cache backends, MemoryKvStore, which is suitable for development, and DenoKvStore, which is only available in Deno.

Now, however, by installing the @fedify/redis package, you can use as both a message queue backend and a cache backend! Unlike DenoKvMessageQueue and DenoKvStore, it's also available for .js and .

This feature was made possible with the support of @ghost.
