A CLI React performance optimization tool that identifies potential unnecessary re-rendering.
Reactopt identifies specific events that may be causing unnecessary re-rendering of components in your application, and which components may benefit from utilizing shouldComponentUpdate.
Prior to React 16, the module react-addons-perf helped identify locations that developers may want to implement shouldComponentUpdate to limit over-rendering. However, since the module is no longer supported we created Reactopt to fill the gap, and also provide increased functionality for any version of React.
Upon initiating Reactopt, your application will be launched in a browser for you to interact with. After you're finished and type 'done', you will see an audit on your application's component performance.
1.5.0 is the first working version of this module. Utilizes async/await, which is natively supported in Node 7.6+.
We welcome contributions that add additional functionality.
npm install --save-dev reactopt
Include this code at the top of your main React component file (our module is meant to be used in development mode):
if processenvNODE_ENV !== 'production'const reactopt = ;;
Include this script in your package.json:
"reactopt": "node node_modules/reactopt/main.js"
