TypeScript decorator for setTimeout() function

I've started to learn how to implement TypeScript decorator in my application. So I started with setTimeout. It's an method decorator which executes method after some time.

For example:

@Decorators.timeout()
 public someMethod () {}

Here is my implementation:

export class Decorators {

  public static timeout (target: Object, propertyKey: string, descriptor: TypedPropertyDescriptor<any>): any {

    let originalMethod = descriptor.value;
    let decArguments = arguments;

    descriptor.value = function Timeout () {

        setTimeout(() => {

          originalMethod.apply(this, decArguments);

        }, 2000);
    };

    return descriptor;

  }

}

This is error I'm getting:

Supplied parameters do not match any signature of call target

What could be the problem?

You are missing args in your Timeout() function and you should pass those args to original method:

descriptor.value = function Timeout (...args) {
  setTimeout(() => {
    originalMethod.apply(this, args);
  }, 2000);
};

You should then delete this line because it's not doing anything:

let decArguments = arguments;
