RUM HTML UI

Rum is a simple, “decomplected” HTML UI library that works on both the client and server, giving Clojure/ClojureScript developers a unified way to build interfaces. On the client, it functions as a thin React wrapper in ClojureScript, exposing familiar component patterns with idiomatic data-driven code. On the server, it generates static HTML from Clojure so the same component concepts can render outside the browser. The library emphasizes control over state and rendering rather than magic, making it suitable for complex single-page apps that still require server-side rendering or templating. The maintainer notes the project is in “support mode,” but it remains a practical, well-documented approach to isomorphic UIs in the Clojure ecosystem. Slides from community talks underline Rum’s strengths around SSR, state models, and fine-grained control for production apps.
