Typescript: how to retrieve Class name?

Question

In typescript how do you retrieve Class name from within the Class itself?

For example, given the following code:

export class SomeRandomName extends AbstractSomething<SomeType> implements OnDestroy {

  className = 'SomeRandomName';

is there a way to automatically assign to className variable the name of the class SomeRandomName?

Thanks in advance.

@enno.void thank you; however, one needs to instantiate a class object first and then assign the class name through instanceOfSomeRandomName.constructor.name. Can I assign it from within the Class itself? — Andrew

You can simply do this:

export class SomeRandomName extends AbstractSomething<SomeType> implements OnDestroy {
      getName() {
        return (this as any).constructor.name;
      }
}

A TypeScript class is just an ES6 class. You can get the name of the class as a string from .constructor.name

class Foo {}

const foo = new Foo();
console.log(foo.constructor.name); // Foo

Thank you; is there a way to assign the class name from within the class itself and not through a class instance, e.g. without creating a class object?

I expect Andrew means: from within the Constructor itself; For the record I have not found a way to access the class prototype from within its own Constructor. But would be pleased if someone finds a way. (I often to this to name instances from within the constructor, and so far it seems to require making a string copy of the class name; seems ugly & not DRY)
