Create a definition file containing a class that can be easily extended

I am attempting to define an interface in a declaration file:

declare namespace Foo{
    export interface Bar{
        new(attrs, options)
    }
}

Then I want to inherit from this interface in my code:

class Chunk extends Foo.Bar {}

However, I encountered the following error -

error TS2507: Type 'any' is not a constructor function type.

What is causing this issue? How should I properly define an extendable class in a declaration file?

Answer №1

Transform the layout into a class structure:


define namespace Foo {
    export class Bar {
        constructor(attributes, settings);
    }
}
