For JWT – Token based Authentication with Web API, we’re gonna call 2 endpoints:

• POST api/auth/signup for User Registration
• POST api/auth/signin for User Login

You can take a look at following flow to have an overview of Requests and Responses that Angular 12 Client will make or receive.

Open app/_helpers/auth.interceptor.js, modify the code to work with x-access-token like this:

...

// const TOKEN_HEADER_KEY = 'Authorization'; // for Spring Boot back-end
const TOKEN_HEADER_KEY = 'x-access-token';   // for Node.js Express back-end

@Injectable()
export class AuthInterceptor implements HttpInterceptor {
  ...

  intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
    ...
    if (token != null) {
      // for Spring Boot back-end
      // authReq = req.clone({ headers: req.headers.set(TOKEN_HEADER_KEY, 'Bearer ' + token) });

      // for Node.js Express back-end
      authReq = req.clone({ headers: req.headers.set(TOKEN_HEADER_KEY, token) });
    }
    return next.handle(authReq);
  }
}

...

Run ng serve --port 8081 for a dev server. Navigate to http://localhost:8081/.
