Alasdair McLeay

Classic jira bug report

@olivtassinari @ReactAdvanced Great to chat to you about Base UI, you didn’t mention you were CEO 😄

This Friday, @ReactAdvanced, it's going to be fun!💂🏻‍♂️🇬🇧

@nationalrailenq @AldiUK Almost certainly a scam uk.trustpilot.com/review/www.nat…

@penx @AldiUK Hi Alasdair, I'll pass this on to our team to look into further.

@nationalrailenq your app is currently running an ad which is likely a scam. It directs to vobivobi.com and then to ourfinaldraw.com which is offering an ebike supposedly for an @AldiUK promotion, but looks suspect

@nikgraf React 17 patches logging during dev mode double renders github.com/facebook/react…

@penx is this not just a Setting in the React dev Tools to gray them out? I would be surprised if React would patch logging in any way

I thought double invocation of useEffect in dev is to show suspense edge cases. I want to replicate a real double invocation, but when a component suspends, the useEffect isn't run. Is there a way to create a real world example for this or have I missed something?

My code is so serious, it errors when run in jest

@nikgraf Cleanups happen after render: The useEffect cleanup function always runs after the component has rendered, not before. (9/9) (yes my counter broke)

@nikgraf Cleanup functions access stale state: Cleanups in useEffect gets the state from when the effect was defined, not the latest - though refs will be up to date. (8/9)

@nikgraf @TkDodo Ah perhaps I figured it out, I need to render without suspending first, then suspend, then re render. So I think "Will fire twice in StrictMode" in @TkDodo 's article becomes a real issue, and the ref fix doesn't work in production either
