Kisspa

The SPA library for your daily life.

Kisspa is a lightweight JSX runtime that keeps SPA (Single Page App) simple - fine-grained reactivity, optional utility CSS, and DOM-first APIs without the framework bloat. With roughly 9 KB of JavaScript (minified + gzip) you still get modern ergonomics such as signals, <Show />/<Switch />, context, portals, suspense alongside a utility-first CSS generator library.

• Tiny & dependency-free – a single package covers the JSX runtime, renderer, and helper utilities.
• Fine-grained reactivity – components automatically re-run only the exact DOM reads that depend on Kisspa’s signal/store primitives, so UI updates stay fast even as components grow.
• DOM-first mental model – JSX compiles to direct DOM operations; No virtual DOM and no one forces you to be purely functional.
• Utility-first CSS included – You don't need a separate CSS library or bundler-specific support for .css files.
