Enum inside class (TypeScript definition file)

Question

I\'ve searched around but can\'t seem to find an answer for this, hopefully you can help. How can I add an enum to Image? This is what I would like ideally but I get an error.

Answer 1

You could create a module and class with the same name. It might also help to rename your enum so that you don't have to say State twice:

declare module 'Lib' {
    export module Graphics {
        export class Image {
            constructor();
        }

        export module Image {
            export enum State {
                Idle,
                Loading,
                Ready,
                Error
            }
        }
    }
}
