Is there a type for "Class" in Typescript? And does "any" include it?

In Java, you can give a class to a method as a parameter using the type "Class". I didn't find anything similar in the typescript docs - is it possible to hand a class to a method? And if so, does the type "any" include such class-types?

Background: I'm having an issue with Webstorm, telling me that I cannot hand over a class to @ViewChild(...) in Angular 2. However, the Typescript compiler does not complain. The signature of @ViewChild() seems to be "Type<any> | Function | string", so I wonder if any includes Classes or not.

Solution 1:

The equivalent for what you're asking in typescript is the type { new(): Class }, for example:

class A {}

function create(ctor: { new(): A }): A {
    return new ctor();
}

let a = create(A); // a is instanceof A

(code in playground)

The code above will allow only classes whose constructor has no argument. If you want any class, use new (...args: any[]) => Class

Solution 2:

The simplest solution would be let variable: typeof Class.

Here an example:

class A {
  public static attribute = "ABC";
}

function f(Param: typeof A) {
  Param.attribute;
  new Param();
}


f(A);
