Matomo Tracker (React)

Stand alone library for using Matamo tracking in React projects

Installation

npm install @jonkoops/matomo-tracker-react

Usage

Before you're able to use this Matomo Tracker you need to create a Matomo instance with your project specific details, and wrap your application with the MatomoProvider that this package exposes.

import { MatomoProvider, createInstance } from '@jonkoops/matomo-tracker-react'

const instance = createInstance({
  urlBase: 'https://LINK.TO.DOMAIN',
  siteId: 3,
  userId: 'UID76903202', // optional, default value: `undefined`.
  trackerUrl: 'https://LINK.TO.DOMAIN/tracking.php', // optional, default value: `${urlBase}matomo.php`
  srcUrl: 'https://LINK.TO.DOMAIN/tracking.js', // optional, default value: `${urlBase}matomo.js`
  disabled: false, // optional, false by default. Makes all tracking calls no-ops if set to true.
  heartBeat: { // optional, enabled by default
    active: true, // optional, default value: true
    seconds: 10 // optional, default value: `15
  },
  linkTracking: false, // optional, default value: true
  configurations: { // optional, default value: {}
    // any valid matomo configuration, all below are optional
    disableCookies: true,
    setSecureCookie: true,
    setRequestMethod: 'POST'
  }
})

ReactDOM.render(
  <MatomoProvider value={instance}>
    <MyApp />
  </MatomoProvider>,
)

After wrapping your application with the MatomoProvider you can use the useMatomo hook to track your application from anywhere within the MatomoProvider component tree:

import React from 'react'
import { useMatomo } from '@jonkoops/matomo-tracker-react'

const MyPage = () => {
  const { trackPageView, trackEvent } = useMatomo()

  // Track page view
  React.useEffect(() => {
    trackPageView()
  }, [])

  const handleOnClick = () => {
    // Track click on button
    trackEvent({ category: 'sample-page', action: 'click-event' })
  }

  return (
    <button type="button" onClick={handleOnClick}>
      Click me
    </button>
  )
}

Advanced usage

By default the Matomo Tracker will send the window's document title and location, or send your own values. Also, custom dimensions can be used:

import React from 'react'
import { useMatomo } from '@jonkoops/matomo-tracker-react'

const MyPage = () => {
  const { trackPageView, trackEvent } = useMatomo()

  // Track page view
  React.useEffect(() => {
    trackPageView({
      documentTitle: 'Page title', // optional
      href: 'https://LINK.TO.PAGE', // optional
      customDimensions: [
        {
          id: 1,
          value: 'loggedIn',
        },
      ], // optional
    })
  }, [])

  const handleOnClick = () => {
    // Track click on button
    trackEvent({ category: 'sample-page', action: 'click-event' })
  }

  return (
    <button type="button" onClick={handleOnClick}>
      Click me
    </button>
  )
}

And you can do the same for the trackEvent method:

import React from 'react'
import { useMatomo } from '@jonkoops/matomo-tracker-react'

const MyPage = () => {
  const { trackEvent } = useMatomo()

  const handleOnClick = () => {
    // Track click on button
    trackEvent({
      category: 'sample-page',
      action: 'click-event',
      name: 'test', // optional
      value: 123, // optional, numerical value
      documentTitle: 'Page title', // optional
      href: 'https://LINK.TO.PAGE', // optional
      customDimensions: [
        {
          id: 1,
          value: 'loggedIn',
        },
      ], // optional
    })
  }

  return (
    <button type="button" onClick={handleOnClick}>
      Click me
    </button>
  )
}

The useMatomo hook also exposes the following methods:

  • trackEvents()
  • trackSiteSearch()
  • trackLink()
  • pushInstruction()

For example, the pushInstruction() function can be used to push instructions to Matomo for execution. This is equivalent to pushing entries into the _paq array.

const { pushInstruction } = useMatomo();
pushInstruction('setUserId', 'USER_ID_HERE');

SPA Link Tracking

Matomo provides the option to track outbound link, however, this implementation is flaky for a SPA (Single Page Application) without SSR (Server Side Rendering) across different versions of Matomo. Therefore you can use the enableLinkTracking method to listen to outbound clicks on anchor elements. This method should be placed on a component directly below your MatomoProvider on a component that's rendered on every page view. Also, make sure to disable the linkTracking option on the instance passed to the provider to prevent Matomo from catching some link clicks:

import { MatomoProvider, createInstance, useMatomo } from '@jonkoops/matomo-tracker-react'

const instance = createInstance({
  urlBase: "https://LINK.TO.DOMAIN",
  linkTracking: false // Important!
});

ReactDOM.render(
  <MatomoProvider value={instance}>
    <MyApp />
  </MatomoProvider>
)

const MyApp = () => {
  const { enableLinkTracking } = useMatomo()

  enableLinkTracking()

  return (
    // Render components
  )
}
