Quick Comparison Vite Webpack Dev server Instant (native ESM) Slower (bundling) HMR Near-instant Slower Config Minimal Verbose Production build Rollup Webpack Plugin ecosystem Growing Massive Learning curve Low High When to Use Vite New projects (it's the default for React, Vue, Svelte) You want fast dev server startup You don't need complex Webpack-specific plugins You value simplicity When to Use Webpack Legacy projects already using Webpack You need Module Federation (micro-frontends) You need a specific Webpack plugin with no Vite equivalent Complex custom build pipelines Key Differences Dev Server: Vite serves files over native ESM — no bundling during development.
