website-performance-hoc

Wrap react components with a HOC measuring page performance metrics. This packages assumes you're tracking via segment and is simply providing a react-y HOC implementation of the website-performance npm module.

Usage

If you've loaded segment globally, and are guranteed to have window.analytics defined before your code runs .. integrating is as easy as:

import withPerformance from 'website-performance-hoc'

class MyPage extends React.PureComponent {
  ...
}

export default withPerformance(window.analytics)(MyPage, { eventName: 'Performance.Track' })

In other cases, you may have asynchronously loaded a tracking library. Integrating would then look something like this:

import withPerformance from 'website-performance-hoc'
import Segment from 'load-segment'
const analytics = Segment({ key: .. })

class MyPage extends React.PureComponent {
  ...
}

export default withPerformance(analytics)(MyPage)

website-performance-hoc can take any analytics provider as long as it has a .track() method, so it should work with Google analytics and Segment. If you're using an analytics provider that doesn't have a .track() method, please open an issue.

We're using componentDidMount in the HOC which can be invoked before the DOM has loaded. In that case, we set window.onload to retry tracking once the window has loaded. We're also deferring the track call to when the browser has free cycles using request-callback.
