Given the following interface
interface Expando {
new<T extends {}>(template: T): T & Expando;
}
I tried to implement this like so
class Expando implements ExpandoConstructor {
constructor(template: {}) {
}
}
But I get an error because the constructor definition is incomplete. How do I implement this interface?
You can't have a class implement a constructor interface because this interface describes static properties of the class.
You can do this:
interface ExpandoConstructor {
new<T extends {}>(template: T): T & Expando;
}
class Expando {
constructor(template: {}) {}
}
let ctor = Expando as ExpandoConstructor;
let instance = new ctor({});
