Log when you update, bruh?

Wat?

A function that monkey patches React and notifies you in the console when component renders occur. Super helpful for easy perf gainzzzzz.

How to

import React from 'react'
 
if (process.env.NODE_ENV !== 'production') {
  const {logWhenYouUpdate} = require('log-when-you-update')
  logWhenYouUpdate(React)
}

You can include or exclude components by their displayName with the include and exclude options

logWhenYouUpdate(React, { include: /^pure/, exclude: /^Connect/ })

I originally read about how Benchling created a mixin to do this on a per component basis (A deep dive into React perf debugging). That is really awesome but also tedious AF, so why not just monkey patch React.
