Utilizing an external TypeScript class without the need for importing it

Question

Utilizing an external TypeScript class without the need for importing it

Let's consider a scenario where we have a class named Constant.

The requirement is to make this class accessible globally without the need for importing, is there a way to achieve this?

In the constant.ts file:

 class Constant {
       public static get TOTAL_FOOD() : number {return 123;}
 }

In the chicken.ts file:

 class Chicken {

      constructor() {
          // I want to access Constant without explicitly importing it like "import {Constant}"
          let totalFood : number = Constant.TOTAL_FOOD;

      }
 }

Answer №1

When creating a class to store constants, it is common practice to use namespaces or export keywords for accessibility from anywhere in the code:

namespace MyConstants {
    export const MAX_USERS: 100;
}

If you prefer using classes, you can declare them as exportable with the export keyword to allow external access:

export class GlobalConstants {
    public static get MAX_USERS() : number {return 100;}
}

When using requirejs to load this file, it becomes necessary to import it in order to use it.

However, an alternative approach is to simply load the file using a script tag instead of requirejs.
In your html, you can include:

<script src="//PATH/TO/constant.js"></script>

In constant.ts, avoid using export and compile it with the declaration files flag (-d). After compiling, you will have:

declare class Constant {
    static readonly TOTAL_FOOD: number;
}

Then, wherever you need it, simply add:

/// <reference path="PATH/TO/constant.d.ts" />

console.log(Constant.TOTAL_FOOD);
