Vite

The build tool that makes front-end dev feel instant.

Vite (Evan You) pairs a native-ESM dev server — instant cold start, near-instant HMR, no bundling on launch — with optimized production builds powered by Rollup. Framework-agnostic, it powers Vue, React, Svelte, SvelteKit, Nuxt and Astro: the right pick to replace Webpack or CRA without sacrificing speed or piling on config.
