FEP drafting: Am I using “side effects” here the same way as other ActivityPub developers? I've seen the term used a bunch in casual conversation, but my personal understanding of it is kinda fuzzy.

#ActivityPub #FediDev #FEP

The "side effects" of an activity are everything caused by the activity other than it being visible in its actor's outbox and getting posted to its audience's inboxes. For example, a like or reply being represented in the affected object's `likes` or `replies` collection is a side effect, as is likes or replies being shown on a web page corresponding to the object.

If you have a fediverse account, you can quote this note from your own instance. Search https://fietkau.social/users/julian/statuses/116035743582215190 on your instance and quote it. (Note that quoting is not supported in Mastodon.)
