Using a static enum in a different class in TypeScript: A guide

After referencing this question and answer on Stack Overflow about setting a static enum inside a TypeScript class, I decided to create my own enum and implement it as a static property in my class. Here is how I did it:

/* Input.ts */
enum INPUT_TYPE { TEXT, RADIO, CHECKBOX }
export class Input {
    static INPUT_TYPE = INPUT_TYPE;
    readonly inputType: INPUT_TYPE;

    constructor (inputType: INPUT_TYPE) {
        this.inputType = inputType;
    }
}

This is just a simple example class for demonstration purposes.

Now, I have another class in a separate file that needs to utilize the previously created class.

import {Input} from "./Input";
/* InputLabel.ts */
export class InputLabel extends Input {
    readonly label: string;

    constructor(label:string, inputType: Input.INPUT_TYPE) {
        super(inputType);
        this.label = label;
    }
}

I am using IntelliJ IDEA and have configured the TypeScript version to match my current version (2.0.2). However, IntelliJ is showing an error stating that it cannot find the namespace 'Input'.

Answer №1

If you desire for it to function in this manner, simply input the following code:

/* Input.ts */
export class Input {
    readonly inputType: Input.INPUT_TYPE;

    constructor (inputType: Input.INPUT_TYPE) {
        this.inputType = inputType;
    }
}
export namespace Input {
    export enum INPUT_TYPE { TEXT, RADIO, CHECKBOX }
}
