Angular Google Tag Manager Service

A service library for integrate google tag manager in your angular project This library was generated with Angular CLI For more info see this how to install google tag manager article

Getting Started

After installing it you need to provide your GTM id in app.module.ts

    providers: [
        ...
        {provide: 'googleTagManagerId',  useValue: YOUR_GTM_ID}
    ],

Or use the module's forRoot method

import { GoogleTagManagerModule } from 'angular-google-tag-manager';

imports: [
    ...
    GoogleTagManagerModule.forRoot({
      id: YOUR_GTM_ID,
    })
]

Or use the APP_INITIALIZER

import { GoogleTagManagerConfiguration } from 'angular-google-tag-manager-config.service';

imports: [
    ...
    GoogleTagManagerModule.forRoot()
]

providers: [
    {
      ...
      provide: APP_INITIALIZER,
      useFactory: configInitializer,
      deps: [
        HttpBackend,
        GoogleTagManagerConfiguration,
      ],
      multi: true,
    },
  ],

set the config in the method assigned to useFactory

googleTagManagerConfiguration.set(googleTagManagerConfiguration);

inject the gtmService in your controller

constructor(
        ...
        private gtmService: GoogleTagManagerService,
    ) { }

then you can start pushing events on your gtm

 this.router.events.forEach(item => {
            if (item instanceof NavigationEnd) {
                const gtmTag = {
                    event: 'page',
                    pageName: item.url
                };

                this.gtmService.pushTag(gtmTag);
            }
        });

if you want to recive tags without pushing events simply call the function to enable it

    this.gtmService.addGtmToDom();

Installing

In your Angular project run

npm i --save  angular-google-tag-manager

Custom configuration and GTM environments

You can pass _gtmpreview and _gtmauth optional variables to your GTM by providing them in app.module.ts

    providers: [
        ...
        {provide: 'googleTagManagerId',  useValue: YOUR_GTM_ID},
        {provide: 'googleTagManagerAuth',  useValue: YOUR_GTM_AUTH},
        {provide: 'googleTagManagerPreview',  useValue: YOUR_GTM_ENV},
        {provide: 'googleTagManagerResourcePath',  useValue: YOUR_GTM_RESOURCE_PATH},
        {provide: 'googleTagManagerCSPNonce',  useValue: YOUR_CSP_NONCE},
        {provide: 'googleTagManagerMode', useValue: "silent" | "noisy"}
    ],

Or using forRoot

import { GoogleTagManagerModule } from 'angular-google-tag-manager';

imports: [
    ...
    GoogleTagManagerModule.forRoot({
      id: YOUR_GTM_ID,
      gtm_auth: YOUR_GTM_AUTH,
      gtm_preview: YOUR_GTM_ENV
    })
]
