Vite

Vite is a free, MIT-licensed frontend build tool, named after the French word for quick, made of a dev server that serves source over native ES modules with very fast hot module replacement and a build command that bundles with Rolldown. Its Rollup-compatible plugin interface makes it the foundation for frameworks such as SvelteKit, SolidStart, Nuxt and Astro, with more than 80 million weekly npm downloads. Design engineers meet it whenever they prototype, since instant feedback on save is its point.
