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. This means instant server start regardless of app size. Webpack bundles everything before serving, which gets slower as your app grows.
Configuration: A Vite config is typically 10-20 lines. A Webpack config can be hundreds of lines with loaders, plugins, and optimization settings.
Production: Vite uses Rollup for production builds, which produces smaller bundles. Webpack uses its own bundler.
Verdict
Use Vite for new projects. Migrate from Webpack to Vite when you can. There’s very little reason to start a new project with Webpack in 2026.
