React Native EU 2019: Emily Janzer - The New React Native

[DominicGo]

I can’t wait for 2020, this is such a game changer for react native and it might also lead to synchronous/performant animation and gesture handling (kinda like react-native-reanimated and react-native-gesture-handler) and, most of all, doing a lot of the heavy lifting in the native side (network and api calls, vision/camera/audio/etc. libraries + offloading tasks to a bg thread) without slowing down the js thread.

This would also mean that things like measuring views, getting x/y/width/height, scroll position and scroll related callbacks, setNativeProps etc. would be fast and synchronous!! No more wrapping things in promises and awaiting them. Native UI events will just fire and call our callbacks immediately 😭

Not to mention libraries like lottie, svg etc. will also be significantly faster. Maybe we can easily animate svg’s without all the hacks and workarounds. And lottie? You’ll no longer have to think about serialization and initializations.

And for things like react-native-gl? Mapping gestures and taps directly? And native modules for AVFoudation and camera api’s? Bridging things like OpenCV?? The fact that you can easily bounce back and forth between native code and javascript will open up a whole new world of possibilities.

Thank you for all the hard work in making react-native even better!

How can I fetch the network data before the js init as mentioned in the end of the talk? Any tutorial or blog about this? Thank you
