Vite (French for “quick”) is a build tool created by Evan You that significantly improves the frontend development experience. It consists of a dev server that serves your source files over native ESM, with rich built-in features and astonishingly fast HMR, plus a build command that bundles your code with Rollup.
Vite has become the default build tool for Vue, Svelte, Solid, and dozens of other modern frameworks — and it powers Vitest for unit testing.
Next-generation frontend tooling. Instant cold start, lightning-fast HMR, Rollup-powered builds.
