However, when I use this at the controller level, it applies both authentication methods to all the routes within the controller. To support multiple specifications, your application must be written with a modular approach. GrpcAuthGuard is an agnostic guard for NestJS optimized for grpc scope. callback function is the only possible customization. However, since this is middleware approach, I am not able to apply any existing Guards (eg, JWT, Role etc) to this proxy. $ npm i --save @nestjs/throttler Once the installation is complete, the ThrottlerModule can be configured as any other Nest package with forRoot or forRootAsync methods. Using guards improve readability and maintainability of your code. Share. Guards are particularly useful for implementing role-based access control (RBAC) and checking Authentication guards allow you to control access to routes and controllers in a NestJS application based on user authentication. Currently, my way of authenticating users is via Passport Local strategy. You can use the APP_GUARD provider in a custom provider in any module in your application and get the guard globally bound. bgnrkg wxr lxfy lcsu hqrkx ktxho irjcw xafm dpntv jidwv
