Within my coding project, I have implemented a decorator that alters a class by adding additional methods to it, specifically in the class A. However, when utilizing an instance of this class, the added methods do not show up in the autocomplete feature. Additionally, compiler errors arise due to these properties not being recognized.
I am aware that decorators are incapable of changing the type of a class, as this functionality is not currently supported. Utilizing mixins is also not preferable in this scenario, as the code will eventually be packaged into a library for use by others. It would be more straightforward if users could simply employ the @ notation.
For instance:
function TypeChangeDecorator(constructor: any) {
const keys = Reflect.getMetadata(SOME_KEY_SYMBOL, TypeB);
return class extends constructor {
private someClass: TypeA;
constructor(...args: any[]) {
super(...args);
for(key in keys) {
this[`set${key}`] = () => {} // some method
}
}
someMethod() {
// implementation here
}
}
}
@TypeChangeDecorator
class A {}
Although I understand that it may not be feasible, I am seeking a way to access the methods someMethod and set${key}. Ideally, I would like to avoid compiler errors when attempting to access these methods and have them readily available in autocomplete.
PS: While current information suggests that this feature is not yet supported, I am open to any insights or suggestions regarding this matter.
