CesiumJS is a JavaScript library for creating 3D globes and 2D maps in a web browser without a plugin. It uses WebGL for hardware-accelerated graphics, and is cross-platform, cross-browser, and tuned for dynamic-data visualization.

Visit the Downloads page to download a pre-built copy of CesiumJS.
If youβre building your application using a module bundler such as Webpack, Parcel, or Rollup, you can install CesiumJS via the cesium npm package:
npm install cesium --saveimport * as Cesium from "cesium";
import "cesium/Build/Cesium/Widgets/widgets.css";
const viewer = new CesiumWidgets.Viewer("cesiumContainer");Or, import individual modules to benefit from tree shaking optmtimizations through most build tools:
import { Viewer } from "cesium";
import "cesium/Build/Cesium/Widgets/widgets.css";
const viewer = new Viewer("cesiumContainer");In addition to the cesium package, CesiumJS is also distrubuted as smaller scoped npm packages:
@cesium/engine- CesiumJS's core, rendering, and data APIs@cesium/widgets- A widgets library for use with CesiumJS
Alternatively, use a content delivery network (CDN) URL to embed CesiumJS in an HTML page.
See our Quickstart Guide for more information on getting a CesiumJS app up and running.
