Steps to apply a decorator to a function that is not a nestjs route

NestJS

Hello there! I am currently facing an issue where I need to apply a decorator to a function that is not serving as an endpoint or route. To illustrate, here is what I have in mind:

class Controller {
      
  @Get('/')
    firstMethod() {
    secondMethod()
  }
      
  @Decorator()
    secondMethod() {}
  }

I want the secondMethod to pass through the Decorator whenever it is called. Can anyone provide guidance on how this can be achieved? Thank you!

Answer №1

Upon reviewing your discussion in Discord and reading through the issue you posted, I now have a better understanding of the request at hand. Simply calling a method and expecting the nest enhancer to function as intended is not possible. The @Use*() decorators in Nest.js only set up metadata that is utilized during route initialization, where the enhancers are then bound to the route handlers. Since the method in question is not a route handler itself, sending a request directly to it would bypass these enhancers. This is because Nest requires control over the request flow for proper execution. While there may be a possibility to call the enhancer directly, this approach could lead to complexity and messy code.
