How to define static property in TypeScript interface

Question

I just want to declare a static property in typescript interface? I have not found anywhere regarding this.

interface myInterface {
  static         


        

Answer 1

I implemented a solution like Kamil Szot's, and it has an undesired effect. I have not enough reputation to post this as a comment, so I post it here in case someone is trying that solution and reads this.

The solution is:

interface MyInterface {
    Name: string;
}

const MyClass = class {
    static Name: string;
};

However, using a class expression doesn't allow me to use MyClass as a type. If I write something like:

const myInstance: MyClass;

myInstance turns out to be of type any, and my editor shows the following error:

'MyClass' refers to a value, but is being used as a type here. Did you mean 'typeof MyClass'?ts(2749)

I end up losing a more important typing than the one I wanted to achieve with the interface for the static part of the class.

Val's solution using a decorator avoids this pitfall.
