Road to 2.0

The master branch has a new, in-progress version of w2ui. You might want to consider 1.5 branch that is stable and supports older browsers. Here are the goals for the new version of w2ui.

Road to 2.0 discussion

W2UI v.2 no longer requires jQuery as a dependency. You can download it from the master branch and at the moment, it is stable enough to be considrered for a Release Candidate. All demos have been updated to work as ES6 modules without any dependencies.

About W2UI

W2UI is a modern JavaScript UI library for building rich web applications. It aims to let you define your UI in a declarative way via JSON data structures.

The library has a small footprint (120KB gzipped) and has NO DEPENDENCIES (as of v2.0). W2UI can be used in Vanilla JS projects, ES6 modules, as well as in Angular, React, and Vue based projects.

The library implements the following UI controls:

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

Quick Start

Current stable version is 1.5 (supports older browsers). Current development version is 2.0.

Getting Started Guide

You can download latest stable version here: http://w2ui.com. If you want to use the dev version, see the 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 are no image dependencies. Some images and font icons are embedded into the CSS file.

There is no requirement for a server side language. Node, Java, PHP, ASP, Perl or .NET will all 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.
