## Documentation

- [Examples](https://github.com/auth0/angular2-jwt/blob/main/EXAMPLES.md) - code samples for common angular-jwt authentication scenario's.
- [Docs site](https://www.auth0.com/docs) - explore our docs site and learn more about Auth0.

This library provides an `HttpInterceptor` which automatically attaches a [JSON Web Token](https://jwt.io) 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](https://angular.io/guide/releases#actively-supported-versions). Whilst other versions might be compatible they are not actively supported

### Installation

```bash
# 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.

```ts
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.

```ts
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)
    );
  }
}
```
