Getting started? Play directly with the Babylon.js API using our playground. It also contains a lot of samples to learn how to use it.

CDN
⚠️ WARNING: The CDN should not be used in production environments. The purpose of our CDN is to serve Babylon packages to users learning how to use the platform or running small experiments. Once you've built an application and are ready to share it with the world at large, you should serve all packages from your own CDN.
npm
BabylonJS and its modules are published on npm with full typing support. To install, use: ``text
npm install babylonjs --save
`
alternatively, you can now rely on our ES6 packages. Using the ES6 version will allow tree shaking among other bundling benefits.
This will allow you to import BabylonJS entirely using:
`javascript
import * as BABYLON from 'babylonjs';
`
or individual classes using:
`javascript
import { Scene, Engine } from 'babylonjs';
`
If using TypeScript, don't forget to add 'babylonjs' to 'types' in tsconfig.json:
`json
...
"types": [
"babylonjs",
"anotherAwesomeDependency"
],
...
`
To add a module, install the respective package. A list of extra packages and their installation instructions can be found on the babylonjs user on npm.
Usage
See Getting Started:
`javascript
// Get the canvas DOM element
var canvas = document.getElementById('renderCanvas');
// Load the 3D engine
var engine = new BABYLON.Engine(canvas, true, {preserveDrawingBuffer: true, stencil: true});
// CreateScene function that creates and return the scene
var createScene = function(){
// Create a basic BJS Scene object
var scene = new BABYLON.Scene(engine);
// Create a FreeCamera, and set its position to {x: 0, y: 5, z: -10}
var camera = new BABYLON.FreeCamera('camera1', new BABYLON.Vector3(0, 5, -10), scene);
// Target the camera to scene origin
camera.setTarget(BABYLON.Vector3.Zero());
// Attach the camera to the canvas
camera.attachControl(canvas, false);
// Create a basic light, aiming 0, 1, 0 - meaning, to the sky
var light = new BABYLON.HemisphericLight('light1', new BABYLON.Vector3(0, 1, 0), scene);
// Create a built-in "sphere" shape using the SphereBuilder
var sphere = BABYLON.MeshBuilder.CreateSphere('sphere1', {segments: 16, diameter: 2, sideOrientation: BABYLON.Mesh.FRONTSIDE}, scene);
// Move the sphere upward 1/2 of its height
sphere.position.y = 1;
// Create a built-in "ground" shape;
var ground = BABYLON.MeshBuilder.CreateGround("ground1", { width: 6, height: 6, subdivisions: 2, updatable: false }, scene);
// Return the created scene
return scene;
}
// call the createScene function
var scene = createScene();
// run the render loop
engine.runRenderLoop(function(){
scene.render();
});
// the canvas/window resize event handler
window.addEventListener('resize', function(){
engine.resize();
});

Contributing
Building and developing this repository requires Node.js 22.22.2 or newer within the Node 22 line, or Node.js 24.16.0 or newer within the Node 24 line, and npm 11.18.0 or newer. These are development-tool requirements; they do not change the runtime requirements of the published Babylon.js libraries.
