How is the best way to get started building apps in the fediverse?
not much beyond "look at what other apps you're trying to interoperate with output and try to reverse engineer your way through". reading through the sources of other apps may be a good idea.
some links that may get you started, picked from https://socialhub.activitypub.rocks/t/guide-for-new-activitypub-implementers/479 :

- https://tinysubversions.com/notes/reading-activitypub/
and depending on which ecosystem you're targeting:
- https://docs.joinmastodon.org/spec/activitypub/
- https://join-lemmy.org/docs/contributors/05-federation.html
counter intuitively, avoid reading the specs if you're looking to federate with existing software. the official specs are... extremely lacking beyond giving you the bullets to shoot yourself in the foot with (half of what little it defines goes unused in the real world, important things like "how do i know this activity is sent by the person it claims to be" is completely undefined (hint: everyone has more or less settled on http signatures).
once you get something federating, you can then look in the specs in an attempt to learn the concepts in depth, but writing code following the specs will result in code that simply won't federate.
I think it may also be worthwhile to toss in Bonfire, if looking for some pieces designed to hack together into a fediverse app. As I was looking up software the other day, I also saw some developing their software with Fedify, so there may be some resources to pull from there.
Tossing a mention to ya OP so you may catch this as well: @sentient_loom@sh.itjust.works
Very nice, thank you.
Read the ActivityPub protocol and a book on webdevelopment... Also have a look at existing projects and their codebase.
lol yeah, that'll do it.
Depends, there is some flask based lemmy server that was pretry easy to read. And u always have the activpub docs but nobody follows them to the t so making everything interoperate is going to be a mindfuck.
