name: vite description: Vite fast build tool with HMR. Use for modern frontend builds.
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.
Plugins
Rollup-compatible plugin system.
Best Practices (2025)
Do:
- Use
vitest: The native test runner for Vite projects. - Use
vite.config.ts: TypeScript config is standard. - Environment API: Use the new API to define custom environments (e.g.
ssr,worker).
Don't:
- Don't use
require: Vite is ESM-first. Useimport.
