JavaScript 3D library

The aim of the project is to create an easy-to-use, lightweight, cross-browser, general-purpose 3D library. The current builds only include WebGL and WebGPU renderers but SVG and CSS3D renderers are also available as addons.

Usage

This code creates a scene, a camera, and a geometric cube, and it adds the cube to the scene. It then creates a WebGL renderer for the scene and camera, and it adds that viewport to the document.body element. Finally, it animates the cube within the scene for the camera.

import * as THREE from 'three';

const width = window.innerWidth, height = window.innerHeight;

// init

const camera = new THREE.PerspectiveCamera( 70, width / height, 0.01, 10 );
camera.position.z = 1;

const scene = new THREE.Scene();

const geometry = new THREE.BoxGeometry( 0.2, 0.2, 0.2 );
const material = new THREE.MeshNormalMaterial();

const mesh = new THREE.Mesh( geometry, material );
scene.add( mesh );

const renderer = new THREE.WebGLRenderer( { antialias: true } );
renderer.setSize( width, height );
renderer.setAnimationLoop( animate );
document.body.appendChild( renderer.domElement );

// animation

function animate( time ) {

	mesh.rotation.x = time / 2000;
	mesh.rotation.y = time / 1000;

	renderer.render( scene, camera );

}

How Sourcemap Explorer detects three

We catch three from two complementary signals: bundled source paths and the embedded package.json. Modern bundlers (webpack, Vite, esbuild, Rollup, Turbopack) preserve the original node_modules/three/ paths inside the JavaScript sourcemap's sources[] array — that's the canonical signal. When the matching package.json is also captured in sourcesContent[], we read the exact version field — patch number included. No regex guessing, no version inference.

  1. 1

    Confirm the site exposes sourcemaps

    In DevTools Network, check the response headers of any application script for `SourceMap` or `X-SourceMap`. Failing that, fetch the script's last 4 KB and look for a `//# sourceMappingURL=` comment.

  2. 2

    Find the package in the bundle

    Open DevTools → Network → reload. Click any application script and look at its sourcemap. Inside, search `sources[]` for entries matching `node_modules/three/` — every match confirms the package is bundled. The matching `sourcesContent[i]` for `node_modules/three/package.json` gives you the exact installed version.

  3. 3

    Read the version directly from package.json

    Run `jq -r '. as $m | $m.sources | to_entries[] | select(.value | endswith("node_modules/three/package.json")) | $m.sourcesContent[.key] | fromjson | .version' bundle.js.map`. Sourcemap Explorer automates the same query in the popup.

FAQ

What is three used for?

JavaScript 3D library

How can I tell if a website is using three?

Open the page in Chrome with the Sourcemap Explorer extension installed and read the Stack tab. We catch `three` from two complementary signals: `node_modules/three/` paths inside the JavaScript sourcemap, and the embedded `package.json` we read for exact-version detection. Without the extension you can do the same lookup manually in DevTools — the steps are listed in the "How Sourcemap Explorer detects" section above.

What is the latest version of three?

0.184.0, as published on the npm registry. The "Recent versions" table on this page lists the most recent 8 releases with their release dates. Sourcemap Explorer reports the version actually bundled into a site, which can lag the latest release by months on real-world deployments.

Detected by Sourcemap Explorer

When a bundle ships sourcemaps, we read the embedded package.json for three and report the precise version. Without sourcemaps, an import / require in the page's scripts is enough to flag it.
