react-addons-perf

See original GitHub issue

React : 15.1.0 react-native : 0.29.0 react-addons-perf : 15.1.0

Is react-addons-perf supported in react-native? I am trying to find where in my JS we have a very expensive task, and cannot get react-addons-perf to print anything to the console.

Furthermore, how would one use either react-addons-perf or the built in perf monitor ui while not in dev mode? Should these tools be trusted in dev mode?

Thank you!

You can use RCTRenderingPerf.js instead of react-addons-perf.

import PrefMonitor from 'react-native/Libraries/Performance/RCTRenderingPerf';

componentDidMount() {

  PrefMonitor.toggle();
  PrefMonitor.start();
  setTimeout(() => {
      PrefMonitor.stop();
  },5000);

}

Where’s the answer? I see @DanielMSchmidt sent the @facebook-github-bot to suggest the question be asked on Stack Overflow, but that’s it. I would like to leverage react-addons-perf but having no luck enabling in a React Native project.
