Install with NPM

NPM METHOD

 What is NPM?

NPM = Node Package Manager

It installs libraries locally in your project.

 Setup Steps

Step 1: Install Node.js

Download from: https://nodejs.org

Check installation:

node -v
npm -v

Step 2: Create project

mkdir three-project
cd three-project
npm init -y

Step 3: Install Three.js

npm install three

Step 4: Install a bundler (VERY IMPORTANT)

Three.js (NPM) needs a bundler like:

• Vite
• 
  

👉 Use Vite (simple and fast)

npm create vite@latest

Then:

cd your-project
npm install
npm run dev

Step 5: Import Three.js

import * as THREE from 'three';
