Here are the steps to run three.js using Node.js and TypeScript:
Create a new directory for your project and navigate to it in your terminal.
Initialize a new Node.js project by running the command
npm initand following the prompts.Install the necessary libraries by running the command
npm install three ts-loader webpack webpack-cli --save-dev.Create a new file called
index.htmlin your project directory and add the following code:
<!DOCTYPE html>
<html>
<head>
<title>Three.js and TypeScript</title>
</head>
<body>
<script src="bundle.js"></script>
</body>
</html>
- Create a new file called
index.tsin your project directory and add the following code:
import * as THREE from 'three';
const scene = new THREE.Scene();
const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
const renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);
const geometry = new THREE.BoxGeometry();
const material = new THREE.MeshBasicMaterial({ color: 0x00ff00 });
const cube = new THREE.Mesh(geometry, material);
scene.add(cube);
camera.position.z = 5;
function animate() {
requestAnimationFrame(animate);
cube.rotation.x += 0.01;
cube.rotation.y += 0.01;
renderer.render(scene, camera);
}
animate();
This code sets up a simple scene with a rotating green cube.
- Create a new file called
webpack.config.jsin your project directory and add the following code:
const path = require('path');
module.exports = {
entry: './index.ts',
module: {
rules: [
{
test: /\.tsx?$/,
use: 'ts-loader',
exclude: /node_modules/,
},
],
},
resolve: {
extensions: ['.tsx', '.ts', '.js'],
},
output: {
filename: 'bundle.js',
path: path.resolve(__dirname, 'dist'),
},
};
This code sets up a webpack configuration for your TypeScript code.
Compile your TypeScript and bundle your code by running the command
npx webpack.Open the
index.htmlfile in your web browser and you should see the rotating green cube.
Congratulations! You've successfully set up a basic three.js scene using Node.js and TypeScript.
