rEFui

rEFui (0.17.4) is a retained-mode JavaScript framework for building UIs across web, native, and embedded environments. It uses signals for reactivity and a JSX-based component model without requiring a framework-specific compiler — any JSX-capable transpiler (Babel, esbuild, SWC, TypeScript) works out of the box. Built-in HMR support via the refurbish plugin for bundlers. The package ships with LLM-generated TypeScript declarations. Key differentiators: toolchain-agnostic design, unified API across web, NativeScript, and embedded (CheeseDOM/Resonance), and a focus on accessible tooling while delivering high-performance UIs.
