I've concluded an older post with a promise to investigate the issues of integration of Play Framework with RequireJS and YUI . Finally I've got some time to resolve all issues so I'm going to showcase a working sample multi-page project in this article. Sample project. Issues. Sample project Play Framework offers a nice official tutorial for RequireJS-support . However, it appeared that not all RequireJS features are fully supported by Play Framework yet (see below in Issues section). So it required some tuning before everything started working. I've published a sample project on github so you're welcome to look into it. Some of the issues that I faced are described in the section below. Here I'm going to show a couple of screenshots of the sample application. This is how one page of the application looks like: Below is the screenshot of the network tab of the Google Chrome developer tools showing all page resources in the production mode. You c...

My first Play Framework application has recently gone live. This time it was the Java version of the framework, next time I may move on to Scala finally. Nevertheless, I've learned a lot and will try to share some knowledge here. The application is meant for managing the data stored in the Dydra graph database ( RDF & SPARQL ). It's a thick client application meaning that the data loading happens in the client JavaScript layer via JSON requests, while routing and user authentication is done by means of Play Framework. Also I've made use of the RequireJS support in Play Framework for dynamic JS module loading. For the UI I've chosen a well-known YUI library . More details are following below. Application architecture. User model and authentication. Dydra database layer and SPARQL client. JavaScript logic and YUI. RequireJS module loading. Application architecture As any web application, this one can be described in terms of MVC pattern . Play Framewor...
