## Getting Started
### NPM packages
ol-ext exists as ES6 modules ([ol-ext](https://www.npmjs.com/package/ol-ext)) and as pure js (deprecated! [openlayers-ext](https://www.npmjs.com/package/openlayers-ext)).
### using ol-ext in a webpack
* For use with webpack, Rollup, Browserify, or other module bundlers, install the npm [ol-ext package](https://www.npmjs.com/package/ol-ext) and link to the node_modules directory:
````
npm install ol-ext
````
OpenLayers is a peer dependencies, so you need to install it as well.
````
npm install ol
````
Then in your js file you can import the classes as follow:
```javascript
import "ol/ol.css"
import "ol-ext/dist/ol-ext.css"
import LayerSwitcher from "ol-ext/control/LayerSwitcher"
```
See the following examples for more detail on bundling ol-ext with your application:
* Using [webpack](https://github.com/darkscript/ol-ol-ext-webpack-example)
* Using [parcel](https://github.com/Viglino/ol-ext-parcel-bundler)
* Using [angular](https://github.com/Viglino/ol-ext-angular)
**Typescript declarations** are avaliable at [Siedlerchr/types-ol-ext](https://github.com/Siedlerchr/types-ol-ext).
```
npm i -D @types/ol-ext@npm:@siedlerchr/types-ol-ext
```
### using ol-ext in a web page
* For use in a web page install the npm [openlayers-ext package](https://www.npmjs.com/package/openlayers-ext) (deprecated):
````
npm install openlayers-ext
````
The library will be available in the `node_modules/openlayers-ext/dist` directory. You can find individual files in the `node_modules/openlayers-ext/lib` directory.
* You can download the [scripts](dist) of the ./dist directory of the repository in your project and insert the .js and .css in your page.
* If you just want to add a `` tag to test things out, you can link directly to the builds from the github rawgit (not recommended in production).
* For compatibility with older browsers and platforms (like Internet Explorer down to version 9 and Android 4.x), the OpenLayers needs to be transpiled (e.g. using Babel) and bundled with polyfills for `requestAnimationFrame`, `Element.prototype.classList`, `Object.assign`and `URL`.
````html
<!-- Openlayers -->
<link rel="stylesheet" href="https://openlayers.org/en/latest/css/ol.css" />
<script type="text/javascript" src="https://openlayers.org/en/latest/build/ol.js">
<-- if you need polyfill --
-- or --
-->
````
### supported Browsers
ol-ext runs on all modern browsers that support HTML5 and ECMAScript 5. This includes Chrome, Firefox, Safari and Edge. For older browsers and platforms like Internet Explorer (down to version 9) and Android 4.x, polyfills for for `requestAnimationFrame`, `Element.prototype.classList`, `Object.assign`and `URL`.
