About W2UI

W2UI is a modern JavaScript UI library for building data-driven web applications. It aims to let you define UI in expressive JSON-like structures. The library has small footprint and has only one dependency - jQuery.

The library implements following UI controls:

The complete library is under 100Kb (minified & gzipped).

Quick Start

Current stable version is 1.5 Current development version is 2.0

Getting Started Guide

You can download latest stable version here: http://w2ui.com. If you want to use dev version, see dist/ folder in the master branch.

To start using the library you need to include into your page:

  • w2ui.js (or w2ui.min.js)
  • w2ui.css (or w2ui.min.css)

All the controls and their css classes are defined inside of these two files. There is no image dependencies, some images are embedded into CSS file, as well as font icons.

There is no requirement for a server side language. Node, Java, PHP, ASP, Perl or .NET all will work, as long as you can return JSON format from the server (or write a converter into JSON format on the client). Some server side example implementations can be found here.
