adding a property in a class inside d.ts file inside node_modules typescript

Question

There is a class called 'Game' inside phaser.d.ts file inside node_modules/phaser.

I want to add an extra property 'GLOBAL' to the class 'Game' without touching node_modules.

how can I achieve it?

You could use whats called augmentation which would look to something along the lines of :

// global.d.ts
declare module 'phaser' {
    interface Game {
       GLOBAL: any;
    }
}

Hope that will help you
