Vanilla JS: You Might Not Need that Library
summary
Live demo shows an open-source coffee-shop app built with a few HTML/CSS/JS files, no CLI or build, that runs fast and installs as a PWA and works offline. Routing uses the browser history API (history.pushState + popstate) for client-side navigation. UI components use Web Components with templates and Shadow DOM for scoped styles, and state updates use Proxy-based reactivity (and mentions signals as an alternative). Code is compatible across modern browsers and the app proves the approach is practical.
