How do I set up JWT authentication in Angular using Angular CLI?

To set up JWT authentication in Angular, you first need to install Angular CLI and create a new project. Then, you can use a library like @auth0/angular-jwt to handle JWT tokens.

What are the steps to install the JWT library?

You can install the JWT library by running npm install @auth0/angular-jwt in your project directory. After that, you need to configure it in your app module.

How do I configure the JWT in my app module?

In your app module, import JwtModule from @auth0/angular-jwt and configure it with a function that returns the token from local storage.

Can you show me an example of the configuration?

Sure! Here's an example:

import { JwtModule } from '@auth0/angular-jwt';

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

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