Features

npm i @pardnchiu/quickui · Documentation

• Zero dependencies, no build step — Native browser APIs power the virtual DOM diff/patch engine, so a single script tag brings it to any existing page.
• Declarative HTML templates — Interpolation, loops, conditionals, two-way binding, and event binding live directly in HTML attributes, so the template is the page itself.
• Batched Proxy reactivity — Deep data mutations trigger a 300ms debounced update that applies only the required DOM patches on the next animation frame.
• Runtime i18n switching — Locales accept either inline objects or JSON file URLs, and a single language switch re-renders both text and attributes.
• Built-in lazy images and inline SVG — IntersectionObserver defers image loading behind a placeholder animation and inlines external SVG files as stylable nodes once they enter the viewport.
