React Conf is back for 2024! Join our co-hosts @Meta and @callstackio May 15-16 in Henderson, Nevada or join the free livestream. Sign up here for updates: conf.react.dev

@joshuaisgross Found you! 😅

Proud to be part of this team and excited to keep building and shipping!

@tomekzaw_ There isn’t a way to map CSS to anything that is available on iOS. Flexbox is not a thing there. You could run yoga at 60 fps and have smooth resizing, yoga is not a blocker for that.

Why does #ReactNative rely so heavily on #Yoga? Yes, it’s faster than iOS layout engines in some benchmarks. But sometimes we need to calculate layout in 60 fps (e.g. resize window). Wouldn’t it be easier to just map CSS styles to platform-specific layouts like React does on web?

@shikasd_ @wiyarmir Speaking from experience? 😅

@wiyarmir The trick is to quit before future you has to deal with the problems

me today at work

We're hiring! That's right, @reactjs is hiring a developer experience engineering manager in London. If you've got a relentless drive to deliver outstanding developer-first experiences, get in touch! metacareers.com/jobs/160367853…

@strvcom There is an update on the bottom of the article that says otherwise.

Meta has released Threads... but there's a catch. They're ensuring its user count stays high by making it only possible to delete your account by deleting your whole IG. techcrunch.com/2023/07/06/thr…

@CipolleschiR just published a post about New Renderer Interop Layer introduced in React Native 0.72. It makes it possible to use non-migrated libraries on the New Architecture. github.com/reactwg/react-…

@cortinico What are you talking about? These features are revolutionary! 😅 Should have played bingo this year as well.

the amount of Android features that i see added to iOS

@cortinico @martinbonnin The wood is from an Apple tree 😅

@martinbonnin @SamuelSusla it's made of wood, can't be more native than that

love how my colleague @SamuelSusla made a meme out of me and he even found the time to laser-cut it!

So happy to have delivered my first talk for @reactnative and @MetroBundler! We're really happy to be back in the community and to be working hard on improving developer experience for React Native users.

it was super awesome to join App.js with the React Native and Metro team today! @_gsathya @alxhnt @motiz88 @SamuelSusla @aandjelkovic @gweterings @robjhogan

about to start @appjsconf

@RubenNorte You forgot to delete this Tweet.

@ospfranco One thing to note is, it is ok to consume a lot of memory if system is able to claim it back when it asks for it.

@ospfranco Without knowing more about your setup, it is hard to tell what's going on. Is this a debug or optimised build? Has garbage collection ran? Where is the memory difference coming from? I would expect higher memory consumption with higher pixel density.

@cnakazawa @ganezasan What is harder to learn, Japanese or Jest?

A book about testing with Jest by @ganezasan. It has a few exclusive pages about Jest’s origins and it teaches you about testing. Step 1: Learn Japanese Step 2: Buy the book Step 3: Write tests 4: 💰💰💰

@sebastienlorber Precisely. We did a lot of perf testing during internal rollout to make sure it is ok in real-world usage. There were some perf wins but they were more modest.

@SamuelSusla I see thanks I guess it's also hard to make a synthetic benchmark simulating real-world heavy bridge usage 😅

We published benchmarks comparing the old and New React Native Architecture and made some improvements along the way! Read more about it at github.com/reactwg/react-…

@sebastienlorber The message in the benchmarks is trying to set performance expectations. If you migrate to the new arch, you are unlikely to see 20% performance boost in your app. For some specific use cases it could be better, like heavy bridge uses.

@sebastienlorber That's indeed confusing. 😅 The motivation page is trying to convey the message how we can share improvements among all platforms, like how View Flattening is now on iOS. There are other examples of improvements coming from VR to Android.
