## What it is
Cljfx is a declarative, functional, and extensible Clojure wrapper around JavaFX for building desktop GUI applications on the JVM. It is inspired by React, Reagent, re-frame, and fn-fx, letting developers describe UIs as Clojure data with subscriptions and events for state management.

## Use cases
- build a desktop gui app in clojure
- declarative javafx ui from clojure data
- react-style component model for jvm desktop apps
- manage desktop app state with events and subscriptions
- cross-platform desktop ui without javascript
- functional alternative to swing or raw javafx

## When to choose
- you are writing a Clojure desktop application on the JVM
- you want a React/Reagent-like declarative model for native GUIs
- you prefer describing UI as immutable data with pure functions
- you need an extensible component lifecycle over JavaFX

## When to avoid
- you need a web or mobile UI rather than a JVM desktop app
- your team does not use Clojure or the JVM
- you need a GUI toolkit other than JavaFX
- you require HiDPI on Linux with legacy JavaFX 8

## Facets
- artifact type: library
- maturity: active
- function: ui-components, frontend-framework, state-management
- domain: desktop-applications, web-development, developer-tools
- platform: jvm, cross-platform
