WebJars-Play

Introduction

This project provides a Play framework controller so that developers using Play can easily access WebJars from their code.

In summary you need to configure a route in your Play application:

# Enable webjar based resources to be returned
GET     /webjars/*file              controllers.WebJarAssets.at(file)

...and then use WebJars within your views:

<script type='text/javascript' src='@routes.WebJarAssets.at(WebJarAssets.locate("jquery.min.js"))'></script>

A user guide for this plugin can be found within the WebJars Documentation.

Requirejs

For single page JavaScript applications support has been provided for the popular require.js toolkit. The webjar-play controller can serve up a flavor of require.js so that the following types of expression will work from JavaScript:

define(['webjars!angular.js'], 
  function() {

The webjars! directive will cause require.js to locate WebJar resources on the server in a similar manner to calling WebJarAssets.locate within views. The difference is that this locating is all done in JavaScript on the client side.

To enable JavaScript WebJar loading declare require.js in a familiar way:

<script data-main="js/app" src="lib/require.js"></script>

...and then configure some routes in your Play! application:

# Obtain require.js with built-in knowledge of how webjars resources can be
# resolved
GET     /lib/require.js             controllers.WebJarAssets.requirejs()

# Enable webjar based resources to be returned
GET     /webjars/*file              controllers.WebJarAssets.at(file)

You're all set - no Play views required!

An example of the require.js support can be found in the angular-seed-play project.
