ClojureScript optimized for modern React development.

;; define components using the `defnc` macro
(defnc greeting

  ;; use helix.dom to create DOM elements
  (d/div "Hello, " (d/strong name) "!"))

;; start your app with your favorite React renderer
(rdom/render ($ app) (js/document.getElementById "app"))


Clojars Project

Install the latest version from clojars in your project.

A version of "react" and "react-refresh" should be installed automatically; install the corresponding version of your favorite renderer (e.g. "react-dom").

shadow-cljs and npm

During development, you'll want to emit ES6 code until polyfills are handled differently. You can do this by passing in a dev compiler configuration:

;; shadow-cljs.edn
  :dev {:compiler-options {:output-feature-set :es6}}}}}

Release builds should be able to emit all the way back to ES3.

shadow-cljs and react-native

See React Native.

lein-cljsbuild / figwheel-main / raw CLJS

Use CLJSJS or package react yourself using webpack, ensuring it is provided as the name "react".
