Installation

Ng Add

You can use the schematics and ng add the library.

ng add angular-auth-oidc-client

And answer the questions. A module will be created which encapsulates your configuration.

angular-auth-oidc-client schematics

Npm / Yarn

Navigate to the level of your package.json and type

 npm install angular-auth-oidc-client

or with yarn

 yarn add angular-auth-oidc-client

Quickstart

For the example of the Code Flow. For further examples please check the Samples Section.

If you have done the installation with the schematics, these modules and files should be available already!

Configuration

Import the AuthModule in your module.

import { NgModule } from '@angular/core';
import { AuthModule, LogLevel } from 'angular-auth-oidc-client';
// ...

@NgModule({
  // ...
  imports: [
    // ...
    AuthModule.forRoot({
      config: {
        authority: '<your authority address here>',
        redirectUrl: window.location.origin,
        postLogoutRedirectUri: window.location.origin,
        clientId: '<your clientId>',
        scope: 'openid profile email offline_access',
        responseType: 'code',
        silentRenew: true,
        useRefreshToken: true,
        logLevel: LogLevel.Debug,
      },
    }),
  ],
  // ...
})
export class AppModule {}

And call the method checkAuth() from your app.component.ts. The method checkAuth() is needed to process the redirect from your Security Token Service and set the correct states. This method must be used to ensure the correct functioning of the library.

import { Component, OnInit, inject } from '@angular/core';
import { OidcSecurityService } from 'angular-auth-oidc-client';

@Component({
  /*...*/
})
export class AppComponent implements OnInit {
  private readonly oidcSecurityService = inject(OidcSecurityService);

  ngOnInit() {
    this.oidcSecurityService
      .checkAuth()
      .subscribe((loginResponse: LoginResponse) => {
        const { isAuthenticated, userData, accessToken, idToken, configId } =
          loginResponse;

        /*...*/
      });
  }

  login() {
    this.oidcSecurityService.authorize();
  }

  logout() {
    this.oidcSecurityService
      .logoff()
      .subscribe((result) => console.log(result));
  }
}

Using the access token

You can get the access token by calling the method getAccessToken() on the OidcSecurityService

const token = this.oidcSecurityService.getAccessToken().subscribe(...);

And then you can use it in the HttpHeaders

import { HttpHeaders } from '@angular/common/http';

const token = this.oidcSecurityServices.getAccessToken().subscribe((token) => {
  const httpOptions = {
    headers: new HttpHeaders({
      Authorization: 'Bearer ' + token,
    }),
  };
});

You can use the built in interceptor to add the accesstokens to your request

AuthModule.forRoot({
  config: {
    // ...
    secureRoutes: ['https://my-secure-url.com/', 'https://my-second-secure-url.com/'],
  },
}),

 providers: [
    { provide: HTTP_INTERCEPTORS, useClass: AuthInterceptor, multi: true },
  ],
