Overview
Use Vite for new projects; keep Webpack only where a loader or plugin has no Vite or Rolldown equivalent. As of 2026-10-01 Vite is at 8.x (Vite 8 shipped 2026-03-12) and uses Rolldown, a Rust bundler, for both dev and production, with Oxc for parsing and transforms. Webpack is on 5.x. Next.js 16 uses Turbopack by default, so the choice mainly applies outside Next.js.
Comparison
| Dimension | Vite 8 | Webpack 5 |
|---|---|---|
| Bundler | Rolldown (Rust), replacing the old esbuild plus Rollup pair | Webpack (JavaScript) |
| Plugins | Vite and Rollup-style plugins; most Vite 7 plugins work through a compatibility layer | Largest loader and plugin catalog |
| Config size | Small vite.config.ts | Long, explicit |
| TypeScript | Built in (Oxc) | ts-loader, Babel, or SWC loader |
| Module Federation | Official @module-federation/vite plugin | Native ModuleFederationPlugin |
| Node requirement | 20.19+ or 22.12+ | Broad |
| Frameworks | Astro, SvelteKit, Nuxt, Remix and React Router, and most starters | Legacy CRA-style apps, custom enterprise builds |
Pick Vite when
Pick Vite for any new React, Vue, Svelte, Solid, or library project.
- The Vite 8 announcement claims builds up to 10 to 30 times faster; treat that as a ceiling and benchmark your own app.
- Vitest reads the same config. See jest-vs-vitest.
- To upgrade a complex Vite 7 app, first switch to
rolldown-viteon Vite 7, then move to Vite 8. - Astro and SvelteKit already run on Vite; no bundler decision remains.
Pick Webpack when
Pick Webpack when the build depends on behavior only Webpack supplies.
- Custom or legacy loaders with no Vite plugin, and long-tuned configs (including Webpack 5’s persistent filesystem cache for CI) where a rewrite has no payoff; benchmark a Vite build before assuming a win.
- Module Federation hosts and remotes already running on Webpack. The official
@module-federation/viteplugin exists, so test your sharing setup before assuming a blocker. - Prefer Rspack when the only goal is a faster Webpack build. Rspack 2.0 (released 2026-04-22) keeps Webpack’s config shape and loader ecosystem, so migration is lighter than rewriting for Vite.
- Next.js apps with custom webpack config: Turbopack is the default in Next.js 16; opt out with
next dev --webpackandnext build --webpack.
Migrate from Webpack to Vite
Map the build config first, then the loaders.
- Port aliases,
DefinePluginconstants, and env handling (import.meta.env.VITE_*) intovite.config.ts. - Replace each loader with a Vite plugin; exotic loaders may need a small plugin.
- Swap
webpack-bundle-analyzerforrollup-plugin-visualizer. - Move
index.htmlto the project root; Vite treats it as the entry.
FAQ
Should I use Vite or Webpack for a new project?
Use Vite 8 for any new React, Vue, Svelte, Solid, or library project; it bundles with Rolldown and transforms with Oxc. Keep Webpack 5 only where a loader or plugin has no Vite or Rolldown equivalent.
How much faster is Vite than Webpack?
The Vite 8 announcement claims builds up to 10 to 30 times faster. Treat that as a ceiling and benchmark your own app.
What is the fastest way to speed up an existing Webpack build?
Move to Rspack 2.0 (released 2026-04-22), which keeps Webpack’s config shape and loader ecosystem. Migration is lighter than rewriting the build for Vite.
Does Vite support Module Federation?
Yes, through the official @module-federation/vite plugin, while Webpack has the native ModuleFederationPlugin. Test your sharing setup before assuming a blocker.
