Ranked in these QuestionsQuestion Ranking
Pro Live, reactive templating
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.
Pro Powerful and extensible
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.
Pro Supports a true templating language
Pro Virtual DOM
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.
Pro Ease of use
Pro In-browser bundler
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.
Pro Web Starter Project
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).
Pro jQuery alike helper
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.
Con Ractive's two way binding can be a source of bugs
Two-way data-binding means that a HTML element in the view and an Ractive model are binded, and when one of them is changed so is the other. One-way data-binding for example does not change the model when the HTML element is changed.
This is a rather controversial subject and many developers consider two-way data binding an anti-pattern and something that is useless in complex applications because it's very easy to create complex situations by using it and being unable to debug them easily or understand what's happening by just looking at the code.
