Stand alone library for using Matamo tracking in React projects. Originally forked from @datapunt/matomo-react. Since he abandoned the project I forked the part of it containing React specific logic since I needed it for a project. I have not tested most of the functionality yet, so there's no guarantee of everything working. Will probably get to test most parts as I wo forward from here. Most of the credits for the code belongs to @datapunt.
yarn add matomo-reactTo use this 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 'matomo-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`
permanentTitle: 'My Awesome App', // optional, always use this title for tracking, ignores document.title. Useful for SPAs.
permanentHref: '/', // optional, always use this href for tracking, ignores window.location.href. Useful for SPAs.
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 'matomo-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>
)
}By default we 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 'matomo-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 'matomo-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')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 'matomo-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
)
