Tips for selecting the right decorator for your space

I am working on developing a game that utilizes an AI. This AI's API consists of 3 methods implemented in an Angular Service

Here is a simplified version of the code:

app.service('AI', [function(){
   return {
     offer: angular.noop,
     accept: angular.noop,
     reject: angular.noop
   }
}])

The challenge lies in the fact that the implementation of these methods (and subsequently, how the AI responds) can vary based on multiple factors such as nationality, age, etc.

I have been considering using Angular Decorators, but I would need to choose from several decorators. One approach could be to create individual files for each implementation:

  • less-than-10.decorator.js
  • less-than-20.decorator.js
  • and so on...

But then I face the question:

"If I have an 18-year-old player... should I load less-than-20.decorator.js and apply the decorator?"

OR

"I have an 18-year-old player... should I use this decorator instead of that one?"

In summary: I wish to implement a conditional loading of decorators.

After some research, I came across a method where instead of returning $delegate, I could return the original service, but I feel like it may not be the most elegant solution...

Do you have any suggestions for a better approach?

Answer №1

Have you thought about utilizing a factory instead of a service?

// catFactory and dogFactory could be values, constants, factories...
app.factory('createPet', function (catFactory, dogFactory) {
   return function (petType) {
       switch (petType) {
       case 'cat':
           return catFactory;
       case 'dog':
           return dogFactory;
       }
   };
});

Then you can inject createPet and use it:

createPet('dog');
