Tested Environment

Successfully tested with Angular 4.3 to Angular 16 and its Router, PathLocationStrategy as well as HashLocationStrategy and CommonJS-Bundling via webpack. At server side we've used IdentityServer (.NET / .NET Core), Redhat's Keycloak (Java), and Auth0 (Auth0 is officially supported since version 10 of this lib). For Auth0, please have a look into the respective documentation page here. For using this library with Azure Active Directory (Azure AD), we recommend an additional look to this blog post and the example linked at the end of this blog post. Also, the Okta community created some guidelines on how to use this lib with Okta. See the links at the end of this page for more information. Angular 17: Use 17.x versions of this library (should also work with older Angular versions!). Angular 16: Use 16.x versions of this library (should also work with older Angular versions!). Angular 15: Use 15.x versions of this library (should also work with older Angular versions!). Angular 14: Use 14.x versions of this library (should also work with older Angular versions!). Angular 13: Use 13.x versions of this library (should also work with older Angular versions!). Angular 12: Use 12.x versions of this library (should also work with older Angular versions!). Angular 11: Use 10.x versions of this library (should also work with older Angular versions!). Angular 10: Use 10.x versions of this library (should also work with older Angular versions!). Angular 9: Use 9.x versions of this library (should also work with older Angular versions!). Angular 8: Use 8.x versions of this library. Angular 7: Use 7.x versions of this library. Angular 6: Use Version 4.x of this library. Version 4.x was tested with Angular 6. You can also try the newer version 5.x of this library which has a much smaller bundle size. Angular 5.x or 4.3: If you need support for Angular < 6 (4.3 to 5.x) you can download the former version 3.1.4 (npm i angular-oauth2-oidc@^3 --save).

Features

Logging in via Code Flow + PKCE

- Hence, you are safe for the upcoming OAuth 2.1

Logging in via Implicit Flow (where a user is redirected to Identity Provider)

"Logging in" via Password Flow (where a user enters their password into the client)

Token Refresh for all supported flows

Automatically refreshing a token when/some time before it expires

Querying Userinfo Endpoint

Querying Discovery Document to ease configuration

Validating claims of the idtoken regarding the specs

Hook for further custom validations

Single-Sign-Out by redirecting to the auth-server's logout-endpoint

Tested with all modern browsers and IE

Token Revocation according to RFC 7009

Sample-Auth-Server

You can use the OIDC-Sample-Server used in our examples. It assumes, that your Web-App runs on http://localhost:4200 Username/Password:

max/geheim

bob/bob

alice/alice

clientIds:

spa (Code Flow + PKCE)

implicit (implicit flow)

redirectUris:

localhost:4200-4202

localhost:4200-4202/index.html

localhost:4200-4202/silent-refresh.html

Installing

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

Option 1: Standalone APIs

If you use Standalone Components introduced with Angular 14, you can use our standalone API (call to `provideOAuthClient) in your main.ts to setup the OAuthClient`: ```TypeScript // main.ts -- Angular 15+ version import { bootstrapApplication } from '@angular/platform-browser'; import { provideHttpClient } from '@angular/common/http'; import { AppComponent } from './app/app.component'; import { provideOAuthClient } from 'angular-oauth2-oidc'; bootstrapApplication(AppComponent, { providers:

provideHttpClient(),

provideOAuthClient()

}); ``` As Angular 14 does have Standalone Components but no Standalone API for its `HttpClient, you need to go with the traditional HttpClientModule` in this version: ```TypeScript // main.ts -- Angular 14 version import { bootstrapApplication } from '@angular/platform-browser'; import { HttpClientModule } from '@angular/common/http'; import { AppComponent } from './app/app.component'; import { provideOAuthClient } from 'angular-oauth2-oidc'; import { importProvidersFrom } from '@angular/core'; bootstrapApplication(AppComponent, { providers:

importProvidersFrom(HttpClientModule),

provideOAuthClient()

}); ``` The `provideOAuthClient` function takes the same parameters as the forRoot function of the OAuthModule that is still in place for the sake of compatibility with existing code bases.

Option 2: Using NgModules

```TypeScript import { HttpClientModule } from '@angular/common/http'; import { OAuthModule } from 'angular-oauth2-oidc'; // etc. @NgModule({ imports:

// etc.

HttpClientModule,

OAuthModule.forRoot()

, declarations:

AppComponent,

HomeComponent,

// etc.

, bootstrap:

AppComponent

}) export class AppModule { } ```

Logging in

Since Version 8, this library supports code flow and PKCE to align with the current draft of the OAuth 2.0 Security Best Current Practice document. This is also the foundation of the upcoming OAuth 2.1. To configure your solution for code flow + PKCE you have to set the responseType to code: ```TypeScript import { AuthConfig } from 'angular-oauth2-oidc'; export const authCodeFlowConfig: AuthConfig = {

// Url of the Identity Provider

issuer: 'https://idsvr4.azurewebsites.net',

// 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: 'server.code',

clientId: 'spa',

// Just needed if your auth server demands a secret. In general, this

// is a sign that the auth server is not configured with SPAs in mind

// and it might not enforce further best practices vital for security

// such applications.

// dummyClientSecret: 'secret',

responseType: 'code',

// set the scope for the permissions the client should request

// The first four are defined by OIDC.

// Important: Request offline_access to get a refresh token

// The api scope is a usecase specific one

scope: 'openid profile email offline_access api',

showDebugInformation: true,

}; ``` After this, you can initialize the code flow using: ```TypeScript this.oauthService.initCodeFlow(); ``` There is also a convenience method initLoginFlow which initializes either the code flow or the implicit flow depending on your configuration. ```TypeScript this.oauthService.initLoginFlow(); ``` Also -- as shown in the readme -- you have to execute the following code when bootstrapping to make the library to fetch the token: ```TypeScript this.oauthService.configure(authCodeFlowConfig); this.oauthService.loadDiscoveryDocumentAndTryLogin(); ```

Logging out

The logOut method clears the used token store (by default `sessionStorage`) and forwards the user to the auth servers logout endpoint if one was configured (manually or via the discovery document). ```typescript this.oauthService.logOut(); ``` If you want to revoke the existing access token and the existing refresh token before logging out, use the following method: ```typescript this.oauthService.revokeTokenAndLogout(); ```

Skipping the Login Form

If you don't want to display a login form that tells the user that they are redirected to the identity server, you can use the convenience function this.oauthService.loadDiscoveryDocumentAndLogin(); instead of this.oauthService.loadDiscoveryDocumentAndTryLogin(); when setting up the library. This directly redirects the user to the identity server if there are no valid tokens. Ensure you have your issuer set to your discovery document endpoint!

Calling a Web API with an Access Token

You can automate this task by switching sendAccessToken on and by setting allowedUrls to an array with prefixes for the respective URLs. Use lower case for the prefixes. ```TypeScript OAuthModule.forRoot({

resourceServer: {

allowedUrls: ['http://www.angular.at/api'],

sendAccessToken: true

}) ``` If you need more versatility, you can look in the documentation how to setup a custom interceptor.

Token Refresh

See docs: https://manfredsteyer.github.io/angular-oauth2-oidc/docs/additional-documentation/refreshing-a-token.html

Routing

If you use the PathLocationStrategy (which is on by default) and have a general catch-all-route (path: '**') you should be fine. Otherwise look up the section Routing with the HashStrategy in the documentation.

Implicit Flow

Nowadays, using code flow + PKCE -- as shown above -- is the recommended OAuth 2/OIDC flow for SPAs. To use the older implicit flow, lookup this docs: https://manfredsteyer.github.io/angular-oauth2-oidc/docs/additional-documentation/using-implicit-flow.html

Breaking Change in Version 9

With regards to tree shaking, beginning with version 9, the JwksValidationHandler has been moved to a library of its own. If you need it for implementing implicit flow, please install it using npm: ``` npm i angular-oauth2-oidc-jwks --save ``` After that, you can import it into your application by using this: ```typescript import { JwksValidationHandler } from 'angular-oauth2-oidc-jwks'; ``` instead of that: ```typescript import { JwksValidationHandler } from 'angular-oauth2-oidc'; ``` Please note, that this dependency is not needed for the code flow, which is nowadays the recommended flow for single page applications. This also results in smaller bundle sizes.

Breaking change in 9.1.0

The use of encodeURIComponent on the argument passed to initImplicitFlow and its Code Flow counterparts was mandatory before this version. Since that was considered a bug, the need to do so was removed. Now the reverse is true if you're upgrading from before 9.0.0: you need to remove any call to encode URI components in your own application, as the library will now do it for you.
