public static const in TypeScript

Question

Is there such a thing as public static constants in TypeScript? I have a class that looks like:

export class Library {
  public static BOOK_SHELF_NONE: stri         


        

Answer 1

Just simply 'export' variable and 'import' in your class

export var GOOGLE_API_URL = 'https://www.googleapis.com/admin/directory/v1';

// default err string message
export var errStringMsg = 'Something went wrong';

Now use it as,

import appConstants = require('../core/AppSettings');
console.log(appConstants.errStringMsg);
console.log(appConstants.GOOGLE_API_URL);

Answer 2

You can do it using namespaces, like this:

export namespace Library {
    export const BOOK_SHELF_NONE: string = 'NONE';
}

Then you can import it from anywhere else:

import {Library} from './Library';
console.log(Library.BOOK_SHELF_NONE);

If you need a class there as well include it inside the namespace: export class Book {...}
