Using Typescript do you prefer your libraries to return promises or something else? with network requests to e.g. hubs on farcaster we can't get instant returns of data. Appreciate feedback on the best way to do it. Here's a proposal by @nazeeh

Not sure I get the question. If it’s an async call, your choice is a promise or a callback. You should choose promise in 2024. It’s composable. Callbacks aren’t. From the image it seems like Nazeeh is comparing promises vs async/await, but they’re both promises, latter is just syntactic sugar.

Yeah one could do await in the library function for you and try to get it to be a call like let value = sum(1,2); Where sum(a, b) = a + b; So it’s atomic?! Or just have dev do let value = await sum(a, b); Or sum(a, b).then( (c) => value = c;) It’s about what is the best way to return for a library function

Possibly even observers? I am mostly unfamiliar with either and just now I forget the await for async calls A LOT! that’s why I am asking for wisdom of /frontend what is best and what people love https://warpcast.com/pjc/0x26681619

> one could do await in the library function No, that’s not how async/await works. Any function that is async is wrapped in a promise automatically. Client must await or chain then. const add = async (a, b) => a + b const sum = await add(1, 1) or add(1, 1).then((sum) => {…}) Both usages fine.
