How to get user's information in Nest.js?

Question

I am using Angular+Nest to develop a website. I have created a service(Angular) so that client can get user\'s information from server when project start up(the same as fresh).

If you really insist on this way (see comments), you can use Interceptors:

@Injectable()
export class GetUserInterceptor implements NestInterceptor {
  constructor(private readonly authService: AuthService) {
  }

  async intercept(context: ExecutionContext, next: CallHandler) {
    const request = context.switchToHttp().getRequest()
    const item = await this.authService.getByToken(/* extract me from headers*/)
    request.user = item
    return next.handle()
  }
}

so AuthGuard is not needed.
