The ol package

The recommended way to use OpenLayers is to work with the ol package. You can install the latest with npm:

npm install ol

Hosted builds for development

If you want to try out OpenLayers without downloading anything (not recommended for production), include the following in the head of your html page:

<script src="https://cdn.rawgit.com/openlayers/openlayers.github.io/master/en/v5.3.0/build/ol.js"></script>
<link rel="stylesheet" href="https://cdn.rawgit.com/openlayers/openlayers.github.io/master/en/v5.3.0/css/ol.css">
