React Native Performance

[@MrBl0m]

@William please share your "flatlist" component

[@HaibertBuilds]

William you could make a video showing how profiler can be used for performance optimization there’s no such video out there!

[@guillaumeRean]

What a great idea ! Because i'm not absolutely sure what you are talking about with those tools :(

[@fernandorojo6311]

Definitely!

[@LeoTM]

There's tons of content on React Profiler since React 16.5 (Sept2018)

[@HaibertBuilds]

@@LeoTM there’s not much on react native and profiler though, specially with reanimated using Flipper

[@dynamiczny8471]

check this out, its a presentation from app.js conference kzbin.info/www/bejne/a4KWh3adgLtjfac

It would be immensely helpful if you could share your virtualized lsit implementation. A proper virtualized list is one of the biggest short-comes of react native in my opinion

[@HaibertBuilds]

These discussion make the listener step up to a higher level of consciousness when it comes to coding with RN.... amazing.

"For us, Rect Nativ Performance is almost like fun" - now that's one masochistic statement

[@omdxp]

Pretty cool podcast, I would like for you 2 to talk about react native windows in the future episodes. I really hope that reanimated 2 would work on Windows platform.

Thank you for this video, I have learnt a lot

[@kylejohnson594]

Great video, insightful how svgs can have such an impact. Excited to see if the skia stuff helps here. I wrote a module called react-native-performance-monitor that can really help testing if optimisations have an effect.

There's a fast virtualized list implementation by discord. It's called dcd-fast-list.

[@mayowadan]

The link on npm to the repo is dead but you can install the package and walk through the source code. I also came across this thread twitter.com/svishnevskiy/status/1192698931370528768?s=20 where discord's CTO linked a gist that someone on the thread has forked.

Hey Willian can you share with us your flatlist implementation. I have a lot issues with the react native implementation

[@anujraghuvanshi07]

I just seen updated UI of CRED App. And instantly got striked that 1 person can help in this . Could you please refer or make video of that ? Open and close animation of CRED app?

[@ludwigvillalba1886]

Thanks for sharing!

[@zxcvnmtgb]

Do you release this also as a podcast? If so, where can I find it? If not, you totally should. Keep up the good work!

[@samzmann]

I'd be super happy if you made a video on RN Performance debugging. I'm even interested in paying for it if you make a course.

[@skylarbarrera2221]

any implementation or cues on your native text component? sounds interesting, would love to work on it

[@mfbx9da4]

Could you do a video on performance profiling tools for react native?

[@NoitSaab]

@Williman can you please share how to use the Text component in a better way? Is it the following: const RCTText = 'RCTText'; function LowerLevelText(props) { return {props.children} }
