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.
