This service lets you integrate Tag Commander in your AngularX (2+) applications easily.

• Official website

• Automatic page tracking
• Set & Get Variables
• Reloading Containers
• Event catching
• Multiple containers

The quick start is designed to give you a simple, working example for the most common usage scenario. There are numerous other ways to configure and use this library as explained in the documentation.

The plugin doesn't replace the standard setup of a container because you may need to use the containers outside of the plugin.

Initialize your datalayer so that it's ready for the container and plugin, without losing any data. Do it as soon as possible on your website like in a <script> block in the head of your webapp.

tc_vars = []

You can install the module from a package manager of your choice directly from the command line

# NPM
npm i ngx-tag-commander

...
import { WindowRef } from 'ngx-tag-commander';
...
import { NgxTagCommanderModule } from 'ngx-tag-commander';

@NgModule({
    ...
    imports: [
        ...
        NgxTagCommanderModule
        ...
    ],
    providers: [WindowRef],
    ..
})

import { TagCommanderService } from 'ngx-tag-commander';
...
export class AppModule {
  constructor(tcService: TagCommanderService) {
    ...
    Promise.all([
      tcService.addContainer('container_body', '/assets/tag-commander-body.js', 'body'),// Replace URL by the one of your container
      tcService.addContainer('container_head', '/assets/tag-commander-head.js', 'head')
    ]).then(() => {
      //Insert the rest of your code here
    })
    ...
  }
}

You are now ready to use the ngx-tag-commander plugin.

import { TagCommanderService } from 'ngx-tag-commander';
...
export class MyComponent {
constructor(private tcService: TagCommanderService) { }
}

first configure the module to track routes in app.module

export class AppModule {
  constructor(tcService: TagCommanderService) {
    ...
    tcService.trackRoutes(true);
    ...
  }
}

then in your routes:

const appRoutes: Routes = [
  {
    path: '',
    redirectTo: '/home',
    pathMatch: 'full',
    data: {
      tcInclude: [{
        'idc':  12,
        'ids': 4056,
        options: {
          // Data Layer options if needed
        }
      },
      {
        'idc':  11,
        'ids': 4055,
      }]
    }
  },
 ];

This will reload the specified containers, with the specified options

The setTcVars call allows you to set your tc_vars.

constructor(private tcService: TagCommanderService) {
    tcService.setTcVars({
    env_template : "shop",
    env_work : "dev",
    env_language : "en",
    user_id : "124",
    user_logged : "true",
    user_age: "32",
    user_newcustomer : "false",
    });
  // you can also override some variable
    if (isNewUser) {
      tcService.setTcVars({
      user_newcustomer : "true",
      });
    }
    // or set/update them individually
    tcService.setTcVar('env_template', 'super_shop');
}

You can use the directive tcSetVars directly on any html node

<html-element class="sm-button green-500" [tcSetVars]="{'env_language': 'fr'}"></html-element>

<!-- other exemple -->
<!-- defaultLanguage being an attribut of your component -->
<div class="sm-button green-500" [tcSetVars]="{'env_template': defaultEnv}"></div>

import { WindowRef } from 'ngx-tag-commander';

constructor(private tcService: TagCommanderService {
	...
	// retrieve container variables
    tcService.getTcVar('your_var_key'));
    // remove variable
    tcService.removeTcVar('your_var_key')
  }

constructor(private tcService: TagCommanderService) {
    // {string} eventLabel the name of your event
    let eventLabel=  'NameEvent';
    // {HTMLElement} element the HTMLelement on which the event is attached
    let element = 'button';
    // {object} data the data you want to transmit
    let data = {"env_language": 'theEventVar'};
  
    tcService.captureEvent(eventLabel,element, data);
   }

<button [tcEvent]="'test'" [tcEventLabel]="'test'" [tcEventObj]="cartItems"> Add Items in ShopCart </button>

In your app.module.ts on one of your routes please write tcInclude inside the data part. You also need to state the event Page in the options.

var idc = '1234';
var ids = '1234';
var options = {
    events: {page: [{},{}]},
    // ...
    // other options
    // ...
};
this.tcService.reloadContainer(ids, idc, options);
// or you can reload all the containers
this.tcService.reloadAllContainers(options);

you need to set tcService.trackRoutes(true); to true in your app configuration

const appRoutes: Routes = [
  {
    path: '',
    redirectTo: '/home',
    pathMatch: 'full',
    data: {
      tcInclude: [{
        idc:  12,
        ids: 4056,
        options: {
          // Data Layer options
        }
      }]
    }
  },
  {
    path: 'home',
    component: IndexPageComponent,
    data: {
      tcInclude: [{
        idc:  12,
        ids: 4056,
        options: {
			// Data Layer options
        }
      }]
    }
  }
];

You can state an exclusion array to your options object like below :

tcInclude: [{
	idc:  12,
	ids: 4056,
	options: {
	    exclusions: [
        "datastorage",
        "deduplication",
        "internalvars",
        "privacy"
    	]
	}
}]

Please see Tag Commander documentation for other options

To help you with your implementaiton we provided a sample application. to run it

ng serve
or
npm start

then go to http://localhost:4200/

With Node 10

After forking you will need to run the following from a command line to get your environment setup:

1. yarn install
