How do I access a static property in typescript from a subclass instance?

Use case: I have a base class that many other classes inherit from. The base class is called HSManagedObject

.

I have another class called HSContext

that stores a dictionary HSManagedObject

where keys are the names of various subclasses and values ​​are lists of instances of those subclasses. I insert them like this:

insertObject(object: HSManagedObject) { 
   this.projectObjects[object.key()].push(object)
}

      

        
        
        
      

    

Since the class names disappear when I minify my javascript (they all become t

), I added a static property for each of the classes key

that uniquely identifies the class in question.

When I add an object to the dictionary, I would like to infer the class name of that object from the instance. Is there a way to get a static variable key

only from an instance when I don't know which subclass it belongs to?

I am currently adding an instance method for each of the subclasses key()

that returns static static key

and calls the instance method to get the class value. It looks like I don't need to do this. So in all my subclasses I have code like this:

static key = "HSRule";
key() {
    return HSRule.key;
}
