Line 11549 (PIXI.InteractionManager = PIXI.InteractionManager || function () {}😉

if (typeof exports !== 'undefined') {
    if (typeof module !== 'undefined' && module.exports) {
        exports = module.exports = PIXI;
    }
    exports.PIXI = PIXI;
} else if (typeof define !== 'undefined' && define.amd) {
    define(PIXI); // <-- because of this PIXI turns undefined
} else {
    root.PIXI = PIXI;
}

I’m using require.js

Possible solution but NOT optimal:

Create a file “otherModules/phaser/phaser-wrapper.js” with this content:

// This exports Phaser to window.
require('phaserUnFixed');
// And then we return it here.
module.exports = Phaser;

Now in your webpack config in resolve.alias add those lines:

        phaserUnFixed        : "nodeModules/phaser/build/custom/phaser-arcade-physics.js",
        phaser               : "otherModules/phaser/phaser-wrapper.js",

This will make your app to load the phaser-wrapper.js file when you request phaser. This file requires the real phaser file which exports the global Phaser variable. Then the module is properly exported.

I’ve done the same for PIXI.
