zUIx.js Review

Requires only basic HTML/Javascript knowledge.

Can pack assets and resources in the browser console with no need for any external tool.

Creating a component is just a matter of creating 3 small files (html, css, js).
Can share and load components across websites.

If you like Node.js and automatic build system, the zuix-web-starter is a "blank" web project featuring LESS, Markdown, Minify, Eslint checks, automatic bundling, PWA optimizations and much more.

Built-in lazy loading feature. Almost transparent.

With automatic fields mapping (data binding).

Built-in DOM helper. Basically a lite subset of jQuery.

The zKit site is a collection of example components ready to use as-is or as a base for creating your own components.
