Pintura is a CommonJS/JSGI-compliant, server-side JavaScript-based framework for building rich Internet application with the REST architectural style, thin storage-oriented server design, and the consistency of end-to-end JavaScript. The Pintura framework forms the core of Persevere 2.0, and is the first framework built to run on multiple CommonJS platforms like node.js, Narwhal/Jack, and Flusspferd/Zest. It utilizes a layered approach to application development that facilitates straightforward, modular web applications.
Pintura is not a traditional MVC web server framework, which often conflate presentation and interaction concerns across the client and server, but rather follows the REST prescription of maintaining simple storage and serialization oriented server also known as thin server architecture or SOFEA. Pintura is designed to cleanly separate the concerns of presentation and interaction on the client, and storage and model logic concerns on the server. This design fits perfectly with comprehensive JavaScript frameworks like Dojo, General Interface, Cappuccino, YUI, and ExtJS that provide client-side MVC. In particular, Dojo has excellent support for standards-based JSON REST interaction that matches perfectly with this server-side framework.
