What changes between Webpack and Vite?

  • webpack.config.js converted to vite.config.ts with equivalent plugin and alias configuration
  • Webpack loaders (babel-loader, css-loader, file-loader) replaced by Vite's built-in transforms and plugins
  • Hot Module Replacement uses Vite's native ESM-based HMR instead of webpack-dev-server
  • Code splitting changes: dynamic import() works natively; splitChunks config replaced by Rollup options
  • Asset handling: file-loader/url-loader patterns replaced by Vite's static asset handling
  • Environment variables: DefinePlugin patterns replaced by import.meta.env
  • DevServer proxy configuration migrates from devServer.proxy to server.proxy in Vite config
  • HTML template: HtmlWebpackPlugin replaced by Vite's built-in index.html processing

Frequently Asked Questions

Why should I migrate from Webpack to Vite?

Vite offers dramatically faster dev server startup (often 10-50x faster) using native ESM, sub-second hot module replacement, and simpler configuration. Build times are also faster thanks to esbuild for transforms and Rollup for production bundles.

Can Vite handle everything Webpack does?

Vite covers the vast majority of Webpack use cases. Some advanced Webpack features like Module Federation require specific Vite plugins. Nivo flags any Webpack features that need special handling in Vite.

How long does a Webpack to Vite migration take?

Most projects complete in 10 to 15 minutes. The migration involves converting your Webpack config, replacing loaders with Vite plugins, and updating environment variable usage. Complex configs with many custom loaders take longer.

What about my custom Webpack loaders?

Nivo maps common loaders to Vite plugins: babel-loader to @vitejs/plugin-react, sass-loader to Vite's built-in Sass support, svg-loader to vite-plugin-svgr, etc. Custom loaders are flagged for manual conversion to Vite plugins.

Will my production bundle be the same size?

Vite uses Rollup for production builds, which typically produces equal or smaller bundles than Webpack. Tree shaking is often more effective. Nivo preserves your chunk splitting strategy using Rollup's manualChunks option.
