slow performance both on iphone 6 and simulator about react-native-swipeout HOT 9 CLOSED

@michalfeher I think it's because it uses TweenState instead of the React Native Animated Api ;)

from react-native-swipeout.

It's because it calls Javascript on each frame. When the dev flag is set to true, each time your component is re rendered (with TweenState), there is a lot of overhead (check of propTypes etc..). When using the Animated Api, you can offThread animations, and update style without re render your component. So even with the dev flag set to true, it will run at 60fps ;)

@ahanriat thanks, could be. but building it with the dev flag set to false made it run 60fps :)

I'm also seeing poor performance. It seems to happen the most after heavy scrolling.

This is with the dev flag set to true.

Whaooo that's rude ! You should try this branch https://github.com/dancormier/react-native-swipeout/tree/dc-redux, it use Animated Api 😄

@ahanriat this is not a jab at you nor your code, simply an observation. I'll check out the branch.

Hi @ahanriat @bsudekum @michalfeher and others,

The current master does use tween-state, which creates this laggy performance. The branch @ahanriat referenced is not yet ready for release, but it's almost done and it does use the RN Animated
API. Hopefully, I can find some time to wrap it up and release this majorly updated version soon. All contributions are welcome!

@bsudekum to clear up any confusion, I don't believe @ahanriat was bothered by your comment, since it's my code causing the issues in that image ;) I think he was trying to articulate that the performance shown in that gif is poor and needs to be remedied (which I agree with)!

Also, for anyone wondering what's left for the next major update:

https://github.com/dancormier/react-native-swipeout/tree/dc-redux#to-do-for-v300-issues

^ feel free to knock out any of those issues as you see fit to expedite the release of v3 of swipeout.

Yeah sorry for the confusion, I just wanted to say that the animation was very very slow ;)
