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.
