Petite Vue is a minimal JavaScript framework (6kb) for adding interactivity to static HTML pages without a build step. It's Vue.js stripped down to the essentials: templates, data binding, and event handling. No router, no store, no complex state management—just progressive enhancement. You write HTML with Vue-like directives (v-if, v-for, @click), include a single script tag, and boom—your page is interactive. It's perfect for static sites, backend-rendered pages, and progressive enhancement workflows.
