Feature Request - attach custom decorators about node-decorators HOT 5 CLOSED

Use middleware

function Access(value) {
	return (req, res, next) => {
		// your logic
	}
}

@Post("/", [Access('CAN_POST_PERMISSION')])
getPost(){
  return "POST ALLOWED"
}

from node-decorators.

I believe you can, you can wrap original function with custom and add extra logic on top, something like:

function Access(rule: string) {
  return (target: object, key: string, descriptor: any) => {
    const handler = descriptor.value;

    descriptor.value = (...args) => {
      if (ALLOWED_RULES.includes(rule) {
        return handler.apply(target, args);
      }
      
      throw new Unauthorized();
    };

    return descriptor;
  };
}

from node-decorators.

but how do i access the request and response objects in the access decorator factory ? so i can directory send the response or use next function if rule exists

from node-decorators.

Currently i am using middleware method but i wanted to use decorators to keep code neat ,

Currently i have two decorators in my mind

Validate(DtoClass) this decorator will take class-validator as input and validate the request and send error if validation fails

and

Access("PERMISSION_NAME") this will validate the request if user have permission to access this api or not

from node-decorators.

Probably there must be a customDecorator function to create a decorator. I'll take a look.
