@expo.dev I have a question - is `react-native-url-polyfill` necessary when using Expo? this docs page implies expo's URL implementation already supercedes the bad one RN ships with, does it do the same thing as url-polyfill? do we need both?

city of london is the best skyscraper district on earth because seemingly the only planning rule they have is “you can build whatever you want so long as it looks stupid and different to everything else”. it works so well!

“is it stupid?”

I was wrong. it was a third thing: the drawer would start animating, it would change the `open` prop, and then an effect would fire starting the animation again (hence jittering back to a previous position)
luckily has already been fixed upstream 😁

question: is this an acceptable way to use RNGH? I don't want the identity of `nativeGesture` to change, so as `drawerGesture` changes I just keep adding them endlessly in an effect
seems cursed but fixes a gnarly perf problem!
![function DrawerGestureRequireFail({children}: {children: React.ReactNode}) {
const drawerGesture = useContext(DrawerGestureContext)
const nativeGesture = useMemo(() => Gesture.Native(), [])
// the drawer gesture identity changes whenever the drawer opens/closes,
// but we don't want the GestureDetector to rerender when that happens
// therefore we just keep adding the gestures every time it changes to the same
// native gesture -sfn
useEffect(() => {
if (drawerGesture) {
nativeGesture.requireExternalGestureToFail(drawerGesture)
}
// TODO: figure out how to clean this up
}, [drawerGesture, nativeGesture])
return <GestureDetector gesture={nativeGesture}>{children}</GestureDetector>

[Perf] Fix drawer jank issue (maybe) by mozzius · Pull Request #8947 · bluesky-social/social-app
The cause of the drawer jank is due to our use of the drawer gesture, as we use it to set requireExternalGestureToFail on the main home screen pager.
Unfortunately, the drawer gesture is in a useMe...

hmmmm. the real question is: why is something that should be entirely UI thread getting janked up by the JS thread?
looking at the drawer code, it looks like it calls `runOnJS` *prior* to triggering the animation. maybe we should start the anim first
also, these are optional callbacks 🤔

yeah lol this completely works on device. love a one-liner
will open a pr with react navigation and finally end the scourge of every react native app having laggy drawers 😇

1. remember to profile your stuff
2. profiling isn’t everything, think deeply about what’s *actually* going on
3. if your fix is suspicious (telltale signs: useEffect, setTimeout, eslint-ignore) it probably is not the optimal solution, and you should keep digging

recently I’ve been using the React Profiler more seriously and I’m quickly finding it to be a very fun and extremely satisfying kind of puzzle
in related news, the drawer menu jank might be fixed soon 🎉
2 1 48I still don’t have a good intuition about when parents/children changing will cause rerenders, especially with “donut” components
1 8the cause of the Drawer Jank was every time the drawer opens, it causes the RNGH gesture for the drawer to change, which causes a GestureDetector to rerender, which causes the entire Home Screen to rerender.
perf pro tip: don’t make the entire screen rerender
