Ractive vs zUIx.js

Ractive.js is a template-driven UI library, but unlike other tools that generate inert HTML, it transforms your templates into blueprints for apps that are interactive by default.

Two-way binding, animations, SVG support and more are provided out-of-the-box – but you can add whatever functionality you need by downloading and creating plugins.

Ractive fully supports a templating language. To be more precise, views are written with a variant of Mustache, which is also extended to support inline JavaScript expressions. Soon it will be able to support other templating languages.

Instead of relying on the DOM, Ractive implements a virtual DOM from scratch, allowing it to calculate precisely what needs to be patched during the next screen refresh. This is orders of magnitude faster than fiddling with the DOM itself.

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.
