npm i adal-angular4

Implement ADAL authentication:

app.module.ts

Open your Angular root module, usually app.module.ts Add the following import

/*Authentication*/
import { AdalService, AdalGuard, AdalInterceptor } from 'adal-angular4';
import { HTTP_INTERCEPTORS } from '@angular/common/http';

Update your @NgModule providers section with the following line:

providers: [AdalService, AdalGuard, {provide: HTTP_INTERCEPTORS, useClass: AdalInterceptor, multi: true }

It should look something like this:

@NgModule({
  declarations: [
    AppComponent,
    ...
  ],
  imports: [
    ...
  ],
  providers: [AdalService, AdalGuard, {provide: HTTP_INTERCEPTORS, useClass: AdalInterceptor, multi: true }, ... ],
  bootstrap: [AppComponent]
})

environment.ts

inside your environment.ts file add your config, this file is created for you when u use the Angular CLI

Usually can be found here: src ├── environements └── environment.ts └── environment.prod.ts

export const environment = {
  production: false,
  config: {
    tenant: 'tenant.onmicrosoft.com',
    clientId: 'app registration id',
    endpoints: {
      'http://localhost:4200/': 'the id'
    }
  }
};

app.component.ts

Then import the following into your root component usually app.component.ts

import { environment } from '../environments/environment';
import { AdalService } from 'adal-angular4';

Init the adal lib by adding the following lines to your constructor or OnInit

export class AppComponent implements {
    constructor(private adalService: AdalService) {
        this.adalService.init(environment.config);
        this.adalService.handleWindowCallback();
    }
}

app-routing.module.ts

You can protect routes by adding the authguard to you route

import the following inside your routing module file usually app-routing.module.ts

import { AdalGuard } from 'adal-angular4';

ex:

const routes: Routes = [
  {
    path: '',
    component: YourComponent,
    canActivate: [AdalGuard]
  }
];

Login / Logout

You can call the login and logout function with the following code.

AdalService needs to be imported in your file

import { AdalService } from 'adal-angular4';
/*Dont forget to initialize*/
constructor(private adalService: AdalService)

Login:

this.adalService.login();

Logout:

this.adalService.logOut();

Check if user is allready authenticated, if not login

Checking if user has allready logged in if not do something

AdalService needs to be imported in your file

import { AdalService } from 'adal-angular4';
/*Dont forget to initialize*/
constructor(private adalService: AdalService)

if (this.adalService.userInfo.authenticated) {
    /*All good*/
} else {
    /*No good*/
}
