Idiomatic ClojureScript interface to modern React.js

"Oh god, I just started learning reagent. Don’t tell me I’ll have to switch" /r/clojure

• API compatibility: React v18.2.0
• UIx v1 is in roman01la/uix repo
• Discuss at #uix on Clojurians Slack
• A slide deck explaining UIx and migration path from Reagent
• Try it out live in ClojureScript Studio

• Run npx create-uix-app@latest my-app to scaffold a new project
• Clone starter template manually from pitch-io/uix-starter

(ns my.app

            [uix.dom]))

(defui button [{:keys [on-click children]}]
  ($ :button.btn {:on-click on-click}

    ($ :<>
      ($ button {:on-click #(set-state! dec)} "-")
      ($ :span state)
      ($ button {:on-click #(set-state! inc)} "+"))))

Note: to ensure you're using the right Node.js version, you can use nvm and run nvm use once in the directory. Otherwise the Node.js version you use is in the .nvmrc file. See nvm repo for more documentation.

1. Update version in core/release.edn, dom/release.edn and in README.md
2. Update docs if needed
3. Update CHANGELOG.md
4. Publish both core and dom packages to Clojars

cd core && CLOJARS_PASSWORD={YOUR_CLOJARS_TOKEN} clj -A:release --skip-tag
cd dom && CLOJARS_PASSWORD={YOUR_CLOJARS_TOKEN} clj -A:release --skip-tag
