Performance measurement with ReactJS

You can't improve something you can't measure. To improve the performance of React components, you should be able to measure it. ReactJS provides with addon tools to measure performance. Import the react-addons-perf module to measure the performance

You can use below methods from the imported Perf module:

• Perf.printInclusive()
• Perf.printExclusive()
• Perf.printWasted()
• Perf.printOperations()
• Perf.printDOM()

The most important one which you will need most of the time is Perf.printWasted() which gives you the tabular representation of your individual component's wasted time

1import Perf from 'react-addons-perf' // ES6
2var Perf = require('react-addons-perf') // ES5 with npm
3var Perf = React.addons.Perf; // ES5 with react-with-addons.js
