ngx-Matomo

Wrapper for Matomo (aka. Piwik) analytics tracker for applications based on Angular 5, 6, 7 & 8.

Warning

This new release of ngx-Matomo has been rebuilt with Angular CLI v8. As a result, the produced library uses Angular Package Format (APF) v8. It has been tested with an Angular 6 application, but if your Angular 5, 6 or 7 application is running into trouble, please log an issue on GitHub.

Installation

Use npm or yarn to add the module to your current project: npm install --save ngx-matomo

Adding Matomo into to your Angular application

You can add Matomo either via script tag or using the MatomoInjector in your root component.

Initialize Matomo via Script Tag

To illustrate the set up, here's the code to inject into your header to initialize Matomo in your application. Matomo's site has the detailed documentation on how to set up communication between Matomo and your application. Make sure you replace the MATOMO_URL with your Matomo server. You can remove all the _paq methods in this script and set them up in your Angular 5+ application.

<!-- Matomo -->
<script type="text/javascript">
  var _paq = _paq || [];
  _paq.push(['trackPageView']);
  _paq.push(['enableLinkTracking']);
  (function() {
    var u="//{$MATOMO_URL}/";
    _paq.push(['setTrackerUrl', u+'matomo.php']);
    _paq.push(['setSiteId', {$IDSITE}]);
    var d=document, g=d.createElement('script'), s=d.getElementsByTagName('script')[0];
    g.type='text/javascript'; g.async=true; g.defer=true; g.src=u+'matomo.js'; s.parentNode.insertBefore(g,s);
  })();
</script>
<!-- End Matomo Code -->

Initialize Matomo via root component and MatomoInjector service

To enable Matomo via your root component you can now inject the MatomoInjector in your root component.

import { Component } from '@angular/core';
import { MatomoInjector } from 'ngx-matomo';

@Component({
  selector: 'app',
  template: `<router-outlet></router-outlet>`
})
export class AppComponent {
  constructor(
    private matomoInjector: MatomoInjector
  ) {
    this.matomoInjector.init('YOUR_MATOMO_URL', YOUR_SITE_ID);
  }
}

Include it in your application

Bootrapping this application is easy. Import MatomoModule into your root NgModule.

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { MatomoModule } from 'ngx-matomo';

import { AppComponent } from './app.component';

@NgModule({
  imports: [
    BrowserModule,
    MatomoModule
  ],
  declarations: [AppComponent],
  bootstrap: [AppComponent]
})
export class AppModule { }

Once that's done you can import MatomoTracker into any component in your application.

// component
import { Component } from '@angular/core';
import { MatomoTracker } from 'ngx-matomo';

@Component({
  selector: 'app',
  template: `<router-outlet></router-outlet>`
})
export class AppComponent {
  constructor(
    private matomoTracker: MatomoTracker
  ) { }

  ngOnInit() {
    this.matomoTracker.setUserId('UserId');
    this.matomoTracker.setDocumentTitle('ngx-Matomo Test');
  }
}

Tracking events

For now tracking events and actions is manual and is not injected into the html.

<button (click)="whatHappensOnClick(1)"></button>

// component
import { Component } from '@angular/core';
import { MatomoTracker } from 'ngx-matomo';

@Component({
  selector: 'app',
  templateUrl: './myButton.html'
})
export class MyComponent {
  constructor(
    private matomoTracker: MatomoTracker
  ) { }

  whatHappensOnClick(someVal){
    /*
     * some code...
     */
    this.matomoTracker.trackEvent('category', 'action', 'name', someVal);
  }
}
