    Getting Started

    using ol-ext in a web page

    npm install openlayers-ext

    The library will be avaliable 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 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 <script> tag to test things out, you can link directly to the builds from the github rawgit (not recommended in production).
    <!-- jQuery -->
    <script type="text/javascript" src=""></script>
    <!-- Openlayers -->
    <link rel="stylesheet" href="" />

    <!-- OL-ext -->
