What is UIx?

UIx is a ClojureScript library. It is a wrapper for React.js that provides idiomatic interface into modern React.

Because UIx is a wrapper library for React, it's highly recommended to learn more about React.js itself and make yourself comfortable with its concepts.

What is modern React?

A set of new APIs that also includes revamped rendering machinery. For more information on that topic read “Introducing Concurrent Mode (Experimental)”.

How's it different from existing ClojureScript libraries?

Existing libraries came out at the time when React didn't have proper scheduling and prioritization mechanism and components had to be declared as JavaScript's classes. Most of the wrappers had to invent its own scheduling on top of React and deal with JS classes while presenting them nicely as normal ClojureScript functions with Hiccup.

Today what we call modern React includes rendering mechanism that takes care of putting stuff on the screen in efficient way and also allows declaring components directly as functions. New APIs, mainly those to deal with side effects and state, allow better modularity and reusability.

While existing code and ClojureScript wrappers can still use newer versions of React they not entirely able to leverage all of the new features and improved rendering without introducing breaking changes.

What does UIx offer?

As ClojureScript wrapper the library offers idiomatic interface into React while trying to be familiar to those who have used existing wrappers.

UIx is using function based components and improved Hiccup interpreter with optional compile-time optimizations. All of these results in significant performance improvements when compared to existing libraries.
