 <base href="/">

 <link href="../node_modules/@angular2-material/core/style/core.css" rel="stylesheet">

 <!-- Polyfill(s) for older browsers -->
 <script src="../node_modules/core-js/client/shim.min.js"></script>

 <script src="../node_modules/zone.js/dist/zone.js"></script>
 <script src="../node_modules/reflect-metadata/Reflect.js"></script>
 <script src="../node_modules/systemjs/dist/system.src.js"></script>

 <script src="../public/js/systemjs.config.js"></script>

 <script>
     System.import('demo').catch(function(err){ console.error(err); });
   </script>
</head>

<body>
 <demo-app>Loading...</demo-app>
 <script src="//angular2disqustest.disqus.com/embed.js"></script>
</body>

</html>

SystemJS

In the SystemJs config file (systemjs.config.js) add a mapping for the package

var map = {
    ...
    'angular2-disqus': 'node_modules/angular2-disqus/lib'
};

and add the package to the list of packages

var packages = {
   ...
   'angular2-disqus': { main: 'disqus.module.js', defaultExtension: 'js' }
};

or for angular-cli

Just install the package and then import the module as below.

Usage

At the relevant level for your app add import the DisqusModule.

For example in app.module.ts

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

import { FormsModule } from '@angular/forms';

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

import { DisqusModule } from 'angular2-disqus';

import { MdCardModule } from '@angular2-material/card';
import { MdToolbarModule } from '@angular2-material/toolbar';
import { MdButtonModule } from '@angular2-material/button';
import { MdInputModule } from '@angular2-material/input';

@NgModule({
    imports: [
        //A2 stuff
        BrowserModule,
        FormsModule,
        //src module
        DisqusModule,
        //material modules
        MdCardModule,
        MdToolbarModule,
        MdButtonModule,
        MdInputModule
    ],
    declarations: [
        AppComponent
    ],
    bootstrap: [
        AppComponent
    ]

})
export class AppModule { }

To add a comments section add it as a nested component on your component and set the pageIdentifier and the pageUrl.

<disqus-thread [page-identifier]="pageIdentifier" [page-url]="pageUrl"></disqus-thread>

The comments section will be reset everytime either page-identifier or page-url are updated and both have a value. Note to avoid issues with comments showing up on the wrong page always set both.
