title: Phaser 3 images in dev folder?
body: <p>I'm following a very basic Phaser 3 example, but the problem is that the <code>dist</code> folder only contains a bundle.js file, and all assets are still loaded from the <code>src</code> folder.</p>
  
  <p>Folder structure:</p>
  
  <pre><code>dist
    - bundle.js
  src
    assets
      - bmo.png
    scenes
      - game-scene.ts
  </code></pre>
  
  <p>Loading code:</p>
  
  <pre><code>  export class GameScene extends Phaser.Scene {
  
    constructor() {
      super({key: "GameScene"});
    }
  
    preload(): void {
      this.load.image('bmo', './src/assets/bmo.png');
    }
  }
  </code></pre>
  
  <p>But now the image is loaded from the <code>src</code> folder! This isn't right is it? 
  How do I export the game including a html file and asset files?</p>
  
  <p>Currently I run webpack using <code>npm run dev</code> to test the game.</p>
