web dependencies for play asset pipeline

I am coming from the Rails world and are now playing with play (2.1). I like that it comes with a kind of asset pipeline, but one thing I am missing is to include web-dependencies there. In Rails, I can add the jquery-rails dependency and include it in my application.js file to make it available.

I stumbled upon http://webjars.org which seems nice, but as far as I can tell I can only include the files directly in a html file.

Is there any way to enable this kind of behavior, or is it planed to be implemented in the near future?

It's not supported in the same way as in Rails (apparently), so the best I've come up with is the following:

  1. Include your WebJars dependencies
  2. Define the WebJars route as documented here
  3. Put your JavaScript file in /app/assets/javascripts
  4. Use RequireJS (as documented here) and the WebJars RequireJS loader to include the WebJars dependency

So, for example, let's say you want to use AngularJS.

Build.scala:

val appDependencies = Seq(
  "org.webjars" % "webjars-play" % "2.1.0-2",
  "org.webjars" % "angularjs" % "1.0.7"
)

conf/routes

GET     /webjars/*file      controllers.WebJarAssets.at(file)

app/assets/javascripts/main.js

require(["webjars!angular.js"], function() {
  console.log(angular.isString(3));
}

app/views/example.scala.html

...
@helper.requireJs(core = routes.Assets.at("javascripts/require.js").url, module = routes.Assets.at("javascripts/main").url)
...

Now the JavaScript console prints "false".
