craco-cesium

Let's use 🌍Cesium with create-react-app today! This is a plugin for @craco/craco. Resium is also recommended.

NOTE: Unmaintained: Vite is recommended rather thant create-react-app

Currently create-react-app development is inactive. Now it would be a good time to start using Vite to start development as it is easier and faster. See Resium documentation for more information.

There are no plans to perform any maintenance on this library. If you have any requests for additional functionality or dependency upgrading, please send us a pull request!

Very very easy usage

1. Create a React project

npm install -g create-react-app
# or
yarn global add create-react-app

create-react-app example
cd example

2. Install modules

In your create-react-app project, install modules:

npm install --save @craco/craco craco-cesium cesium resium
# or
yarn add @craco/craco craco-cesium cesium resium

3. Rewrite npm scripts

Rewrite npm scripts in package.json as following:

{
  // ...
  "scripts": {
    "start": "craco start", // react-scripts -> craco
    "build": "craco build", // react-scripts -> craco
    "test": "craco test",   // react-scripts -> craco
    "eject": "react-scripts eject"
  },
  // ...
}

4. Create craco config file

Create craco.config.js in the project root:

module.exports = {
  plugins: [
    {
      plugin: require("craco-cesium")()
    }
  ]
};

5. Congratulations! 🎉

Set up is complete! Enjoy your Cesium life.

You can import Cesium as following:

import { Viewer, Entity, Color } from "cesium";

If you are using Resium, you can import Cesium and Resium as following.

import { Color } from "cesium";
import { Viewer, Entity } from "resium";

🔥Pro Tip: Enabling HMR

  • 💡 Example project is here.
  1. yarn add craco-plugin-react-hot-reload react-hot-loader @hot-loader/react-dom

⚠️ @hot-loader/react-dom's version should be the same as react's.

  1. Add an alias of webpack and craco-plugin-react-hot-reload plugin to craco.config.js:
module.exports = {
  webpack: {
    alias: {
      "react-dom": "@hot-loader/react-dom"
    }
  },
  plugins: [
    { plugin: require("craco-plugin-react-hot-reload") },
    { plugin: require("craco-cesium")() }
  ]
};
  1. Wrap root component with hot function in src/App.js
export default App;

to

import { hot } from "react-hot-loader/root";

// ~~~~~~~~~~~~~~~~~~~~~~~~~

export default hot(App);

Done!

Please refer to react-hot-loader to refer to the details.

Options

If the option is omiited, the default options is used:

CracoCesiumPlugin({
  loadPartially: false,
  loadCSSinHTML: true,
  cesiumPath: "cesium",
});

loadPartially

If false, whole Cesium will be loaded in HTML and window.Cesium is used in import { ... } from "cesium";. This is the easiest way.

Otherwise, Cesium will be load partially and bundled in the JS. You have to install strip-pragma-loader to build Cesium for production: npm i -S strip-pragma-loader.

For more details, refer to Cesium official tutorial.

loadCSSinHTML

If true, Widgets/widgets.css in Cesium is loaded in HTML.

Otherwise, you have to load the CSS once manually as following.

If loadPartially is true:

import "cesium/Widgets/widgets.css";

Otherwise:

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

cesiumPath

Directory path destination to copy Cesium files.
