Wrap require with a timer for debugging slow loading modules

timed-require.js

const Timer = () => {
  let startTime = new Date()
  return {
    end () {
      return (new Date() - startTime) / 1000
    }
  }
}

const timedRequire = (require) => (path) => {
  const timer = Timer()
  const requiredModule = require(path)
  console.log(`${timer.end().toFixed(2)} ${path}`)
  return requiredModule
}

// eslint-disable-next-line no-global-assign
require = timedRequire(require)
