angular-oauth2-oidc-codeflow


angular-oauth2-oidc-codeflow is an OAuth2 and OpenId Connect (OIDC) client for Angular.
The library is a Github fork of manfredsteyer/angular-oauth2-oidc.
The code of this library is found at bechhansen/angular-oauth2-oidc.

The fork extends the existing library so it do also support:
- Authorization Code Grant flow

Installing

``
npm i angular-oauth2-oidc-codeflow --save
`

Importing the NgModule

`TypeScript
import { OAuthModule } from 'angular-oauth2-oidc-codeflow';
[...]

@NgModule({
imports: [
[...]
HttpModule,
OAuthModule.forRoot()
],
declarations: [
AppComponent,
HomeComponent,
[...]
],
bootstrap: [
AppComponent
]
})
export class AppModule {
}

`

Configuring for Code Grant Flow

To configure the library the following sample uses the new configuration API introduced with Version 2.1.
Hence, The original API is still supported.

`TypeScript
import { AuthConfig } from 'angular-oauth2-oidc-codeflow';

export const authConfig: AuthConfig = {

// Url of the Identity Provider
issuer: 'https://steyer-identity-server.azurewebsites.net/identity',

// URL of the SPA to redirect the user to after login
redirectUri: window.location.origin + '/index.html',

// The SPA's id. The SPA is registerd with this id at the auth-server
clientId: 'spa-demo',

// set the scope for the permissions the client should request
// The first three are defined by OIDC. The 4th is a usecase-specific one
scope: 'openid profile email voucher',
}
`

Configure the OAuthService with this config object when the application starts up:

`TypeScript
import { OAuthService } from 'angular-oauth2-oidc';
import { JwksValidationHandler } from 'angular-oauth2-oidc';
import { authConfig } from './auth.config';
import { Component } from '@angular/core';

@Component({
selector: 'flight-app',
templateUrl: './app.component.html'
})
export class AppComponent {

constructor(private oauthService: OAuthService) {
this.configureWithNewConfigApi();
}

private configureWithNewConfigApi() {
this.oauthService.configure(authConfig);
this.oauthService.tokenValidationHandler = new JwksValidationHandler();

this.oauthService.loadDiscoveryDocumentAndTryLogin().then(_ => {
console.log("Logged in");
}).catch(err => {
console.log("Unable to login");
})


// Call this.oauthService.tryLogin() if discovery document is not used.
// All configurations must be set manually.
}
}
`

To initialize the login login flow, make a button call 'initAuthorizationCodeFlow()':
`TypeScript
this.oauthService.initAuthorizationCodeFlow();
