The packages we installed are typescript, webpack, webpack-cli, ts-loader, and three.

Set up TypeScript configuration by creating a tsconfig.json file in the root of the project folder. In the file, add:


index.ts
{
  "compilerOptions": {
    "target": "es5",
    "module": "commonjs",
    "sourceMap": true
  }
}

Create a webpack.config.js file in the root of the project folder:


index.ts
const path = require('path');

module.exports = {
  mode: "development",
  entry: "./src/index.ts",
  output: {
    filename: "bundle.js",
    path: path.resolve(__dirname, "dist")
  },
  devtool: "source-map",
  resolve: {
    extensions: [".ts", ".js"]
  },
  module: {
    rules: [
      {
        test: /\.tsx?$/, // Match all .ts and .tsx files
        use: "ts-loader",
        exclude: /node_modules/
      }
    ]
  }
};

Create the game's main file under the src/ folder, for example, index.ts. In the file, add:


index.ts
import * as THREE from 'three';

// Set up the scene, camera and renderer
const scene = new THREE.Scene();
const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
const renderer = new THREE.WebGLRenderer();

// Set up the size of the renderer
renderer.setSize(window.innerWidth, window.innerHeight);

// Add the renderer to the DOM
document.body.appendChild(renderer.domElement);

// Create a mesh
const geometry = new THREE.BoxGeometry();
const material = new THREE.MeshBasicMaterial({ color: 0x00ff00 });
const cube = new THREE.Mesh(geometry, material);

// Add the mesh to the scene
scene.add(cube);

// Update the renderer
function animate() {
  requestAnimationFrame(animate);

  cube.rotation.x += 0.01;
  cube.rotation.y += 0.01;

  renderer.render(scene, camera);
}
animate();
