Documentation

• Docs site - explore our docs site and learn more about Auth0.

This library provides an HttpInterceptor which automatically attaches a JSON Web Token to HttpClient requests.

This library does not have any functionality for (or opinion about) implementing user authentication and retrieving JWTs to begin with. Those details will vary depending on your setup, but in most cases, you will use a regular HTTP request to authenticate your users and then save their JWTs in local storage or in a cookie if successful.

Getting started

Requirements

This project only supports the actively supported versions of Angular as stated in the Angular documentation. Whilst other versions might be compatible they are not actively supported

Installation

# installation with npm
npm install @auth0/angular-jwt

# installation with yarn
yarn add @auth0/angular-jwt

Configure the SDK

Import the JwtModule module and add it to your imports list. Call the forRoot method and provide a tokenGetter function. You must also add any domains to the allowedDomains, that you want to make requests to by specifying an allowedDomains array.

Be sure to import the HttpClientModule as well.

import { JwtModule } from "@auth0/angular-jwt";
import { HttpClientModule } from "@angular/common/http";

export function tokenGetter() {
  return localStorage.getItem("access_token");
}

@NgModule({
  bootstrap: [AppComponent],
  imports: [
    // ...
    HttpClientModule,
    JwtModule.forRoot({
      config: {
        tokenGetter: tokenGetter,
        allowedDomains: ["example.com"],
        disallowedRoutes: ["http://example.com/examplebadroute/"],
      },
    }),
  ],
})
export class AppModule {}

Any requests sent using Angular's HttpClient will automatically have a token attached as an Authorization header.

import { HttpClient } from "@angular/common/http";

export class AppComponent {
  constructor(public http: HttpClient) {}

  ping() {
    this.http.get("http://example.com/api/things").subscribe(
      (data) => console.log(data),
      (err) => console.log(err)
    );
  }
}

Using with Standalone Components

If you are using bootstrapApplication to bootstrap your application using a standalone component, you will need a slightly different way to integrate our SDK:

import { JwtModule } from "@auth0/angular-jwt";
import { provideHttpClient, withInterceptorsFromDi } from "@angular/common/http";

export function tokenGetter() {
  return localStorage.getItem("access_token");
}

bootstrapApplication(AppComponent, {
    providers: [
        // ...
        importProvidersFrom(
            JwtModule.forRoot({
                config: {
                    tokenGetter: tokenGetter,
                    allowedDomains: ["example.com"],
                    disallowedRoutes: ["http://example.com/examplebadroute/"],
                },
            }),
        ),
        provideHttpClient(
            withInterceptorsFromDi()
        ),
    ],
});

As you can see, the differences are that:

• The SDK's module is included trough importProvidersFrom.
• In order to use the SDK's interceptor, provideHttpClient needs to be called with withInterceptorsFromDi.
