cesium-webpack-example

A minimal recommended setup for an applications using Cesium with Webpack.

Running this application

npm install
npm start

Navigate to localhost:8080.

Available scripts

• npm start - Runs a webpack build with webpack.config.js and starts a development server
• npm run build - Runs a webpack build with webpack.config.js
• npm run release - Runs an optimized webpack build with webpack.release.config.js
• npm run serve-release - Runs an optimized webpack build with webpack.release.config.js and starts a development server

Configurations

We've included two webpack configuration files in this repository. webpack.config.js contains configuration for development while webpack.release.config.js contains an optimized configuration for production use.

Requiring Cesium in your application

We recommend using Cesium as an ES6 module, via the import keyword.

Import named modules from Cesium

import { Color } from 'cesium';
var c = Color.fromRandom();

Import Cesium static asset files

import "cesium/Build/Cesium/Widgets/widgets.css";

Treeshaking

webpack.release.config.js enables tree-shaking of CesiumJS modules so that unused modules are not included in the production bundle. See Webpack's Tree Shaking documentation for more details.

Removing pragmas

To remove pragmas such as a traditional Cesium release build, use the strip-pragma-loader.

Install the plugin with npm,

npm install strip-pragma-loader --save-dev

and include the loader in module.rules with debug set to false.

rules: [{
	test: /\.js$/,
	enforce: 'pre',
	include: path.resolve(__dirname, cesiumSource),
	use: [{
		loader: 'strip-pragma-loader',
		options: {
		    pragmas: {
				debug: false
			}
		}
	}]
}]
