Spring JS is designed such that an implementation of its API can be built for any of the popular Javascript toolkits. The initial implementation of Spring.js builds on the Dojo toolkit.

Using Spring Javascript in a page requires including the underlying toolkit as normal, the Spring.js base interface file, and the Spring-(library implementation).js file for the underlying toolkit. As an example, the following includes obtain the Dojo implementation of Spring.js using the ResourceServlet:

<script type="text/javascript" src="<c:url value="/resources/dojo/dojo.js" />"> </script>
<script type="text/javascript" src="<c:url value="/resources/spring/Spring.js" />"> </script>
<script type="text/javascript" src="<c:url value="/resources/spring/Spring-Dojo.js" />"> </script>
        

When using the widget system of an underlying library, typically you must also include some CSS resources to obtain the desired look and feel. For the booking-mvc reference application, Dojo's tundra.css is included:

<link type="text/css" rel="stylesheet" href="<c:url value="/resources/dijit/themes/tundra/tundra.css" />" />
