SigPro ⚡
The Ultra-Lightweight, Atomic Reactive Engine.
SigPro is a modern, minimalist JavaScript engine designed for developers who want surgical reactivity without the overhead. It weighs less than 2KB, uses a high-performance signal-based architecture, and features a built-in router and native state persistence.
🚀 Why SigPro?
Unlike traditional frameworks that use a Virtual DOM (React) or complex Compilers (Svelte), SigPro uses Atomic Reactivity.
- Surgical Updates: When a Signal changes, SigPro knows exactly which text node or attribute needs to update. It doesn't "diff" trees; it directly touches the DOM.
- Zero Dependencies: No extra libraries, no heavy runtimes. Just pure, optimized JavaScript.
- Synchronous by Design: Eliminates the "async-bottleneck". Your app environment is ready the moment you import it.
