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

I also bumped into this problem recently. This is what I am currently using as a solution:

// File: Image.ts

class Image
{
    constructor()
    {
        this.state = Image.State.Idle;
    }

    state: Image.State;
}

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

export = Image;

Then in the place where I'm using the class and its enum:

import Image = require("Image");

let state = Image.State.Idle;
let image = new Image();
state = image.state;

This seems to work fine (even though I don't consider it as the expected way to do this kind of thing).

Hopefully there will be a way in TypeScript to do it this way:

class Image
{
    enum State
    {
        Idle,
        Loading,
        Ready,
        Error
    }

    constructor()
    {
        this.state = State.Idle;
    }

    state: State;
}

export = Image;
