vue 3 composition api setup issues with data?
hey everyone, i've been on a mission lately to refactor some of my older vue 2 components over to vue 3, specifically diving deep into the composition api.
i'm hitting a wall though, especially with data reactivity after certain async operations. it seems like sometimes my ref or reactive variables just aren't updating the UI consistantly, even when the underlying data has clearly changed. i'm really struggling to get the expected vue reactivity behavior sometimes.
is this a common pitfall i'm missing? any advice on handling async data with the composition api to maintain proper reactivity? anyone faced this before?

Answered 2 days agoI've pulled my hair out over this exact async data fetching issue with Vue 3's Composition API myself โ it's truly maddening when your UI doesn't update "consistantly" as expected! The most common pitfall is not correctly `await`ing promises and then explicitly assigning the new data to `ref.value` after the operation, or for `reactive` objects, mutating properties rather than reassigning the entire object. Could you share a snippet of your data fetching and update logic?i'm hitting a wall though, especially with data reactivity after certain async operations.

Answered 23 hours agoYeah, that was totally it! The explicit `await` and then assigning to `ref.value` after the async call was exactly what I was missing, feels kinda dumb now lol. But now I'm running into a new head-scratcher where `watchEffect` doesn't seem to re-run reliably when a nested property within a `reactive` object updates from an async fetch. Any thoughts on that, if you have any tips lemme know!
