Angular gtag.js

A simple Google Analytics gtag.js package for Angular.

This project is a successor to @codediodeio's angular-gtag project.

Install

npm install @bacongobbler/ngx-gtag --save

Add the package to to your app.module.ts:

import { GtagModule } from 'ngx-gtag';

@NgModule({
  imports: [
    GtagModule.forRoot({ trackingId: 'YOUR_TRACKING_ID' })
  ]
})

Pageviews

The package will listen to route changes by default.

You just need to instantiate the service in the root of the project.

export class AppComponent {
  constructor(gtag: GtagService) { }
}

Gtag is a service that also allows you to track pageviews manually.

gtag.pageview();

// or with custom params

gtag.pageview({
  page_title: 'Lesson Feed',
  page_path: '/lessons',
  page_location: 'https://angularfirebase.com/lessons'
});

Events

Events expect an action.

gtag.event('view_promotion')

You can optionally pass in addtional params.

gtag.event('login', {
  method: 'Instagram',
  event_category: 'engagemnt',
  event_label: 'New user logged in via OAuth'
});

Event Directive

Many analytics events are tracked based on user interaction, such as button clicks. Just tell it which DOM event to track.

<button gtagEvent trackOn="click">Track Me</button>

This will register a general event in Google Analytics based on the event name.

You can pass optional params to the directive like so:

<div gtagEvent
     trackOn="dragstart"
     action="product_dragged"
     category="ecommerce"
     [params]="{ event_label: 'Something cool just happened' }">

   Some Product...

</div>

The directive will produce the following event on dragstart:
