react-native-performance-limiter

A package for intentionally lowering performance and generating crashes on React Native applications.

Use blockJavascriptThread and blockNativeMainThread to test your implementation of performance monitoring tools, crashJavascriptThread and crashNativeMainThread to test your implementation of crash reporting tools.

Installation

``sh
npm install react-native-performance-limiter
`

`sh
yarn add react-native-performance-limiter
`

Then re-install your pods:

`sh
(cd ios && pod install)
`

Usage

$3

`js
import { blockJavascriptThread } from 'react-native-performance-limiter';

blockJavascriptThread(1000); // blocks javascript thread for 1 second
`

$3

`js
import { blockNativeMainThread } from 'react-native-performance-limiter';

blockNativeMainThread(1000); // blocks native main thread for 1 second
`

Inside functions you can await for the block to be finised:

`js
const myfun = async () => {
await blockNativeMainThread(1000);
// do something else afterwards
};
`

$3

`js
import { crashJavascriptThread } from 'react-native-performance-limiter';

crashJavascriptThread('custom error message');
`

$3

`js
import { crashNativeMainThread } from 'react-native-performance-limiter';

crashNativeMainThread('custom error message');
``
