rEFui

Run `npx skills add SudoMaker/rEFui --all -g -y` in your terminal to install the rEFui skill globally for your coding agent.

rEFui is a retained-mode JavaScript UI framework where components run once as setup and signals update the UI incrementally. It works across web, native, and embedded targets with any JSX-capable toolchain.

You likely read `.value` directly in JSX, which evaluates only once. Pass the signal itself like `{count}` or wrap derived logic in `$(() => ...)`, and call `sig.trigger()` after mutating arrays or objects in place.

No. rEFui has no re-render cycle, so React hooks like useState do not apply. Use signals for state, `watch` for reactive effects, and `useEffect` or `onDispose` for setup and cleanup.

Yes. The HTML renderer produces serializable server-rendered trees, and the refurbish plugin adds HMR support for Vite, Bun, and webpack.
