Toolchain to measure and monitor the performance of your React Native app in development, pipeline and in production.

An implementation of the Performance API for React Native.

• Integrates well with React.Profiler API
• Trace arbitrary events in your app such as component render time
• Capture network traffic
• Collect native traces such as script execution and time to interactive of root view
• Collect native metrics in development such as JS bundle size

Isomorphic Performance API for Node, Browser & React Native. Useful if your app targets both web and native.

See the projects in the examples folder.

With Flipper deprecated, the best replacement is currently Rozenite that supports react-native-performance out of the box with an official plugin.

Make sure to have yarn v1 installed and run yarn in the root folder to install dependencies for all packages.

Run the example app with:

cd examples/vanilla
yarn start # important to run this before the next step!
yarn ios # or yarn android

Run the unit tests with:

yarn test
