Vite

Vite is the standard build tool for modern web development. v6.0 (2025) introduces the Environment API for runtimes like Bun/Deno and native Sass support.

When to Use

• New Projects: The default for React, Vue, Svelte, etc.
• SPA: Optimized for Single Page Apps.
• Speed: Instant server start via native ESM.

Core Concepts

Dev Server (ESM)

Vite serves files as native ESM modules. The browser downloads files as needed. No bundling in dev.

Rollup Build

Vite uses Rollup for production builds, ensuring highly optimized chunks.
