Migrate Webpack 5 Config to Vite (10x Faster HMR)
Convert webpack.config.js bundles into lightning-fast Vite configs (vite.config.ts). Eliminate multi-minute cold starts and reload delays.
import { defineConfig } from 'vite';
import react from '@vitejs/plugin-react';
import path from 'path';
// Migrated from webpack.config.js (TypeScript React detected)
export default defineConfig({
plugins: [react()],
resolve: {
alias: {
'@': path.resolve(__dirname, './src'),
},
},
server: {
port: 3000,
open: true,
},
build: {
outDir: 'dist',
sourcemap: true,
},
});
Detected Breaking Changes & Semantic Shifts (2)
Vite leverages native browser ES modules during development instead of bundling whole dependency trees.
In Vite, index.html lives in the project root and references `<script type="module" src="/src/main.tsx">`.
How to Migrate from Webpack 5 to Vite
- 1
Paste your webpack.config.js configuration file.
- 2
The migrator converts entry points and path aliases to Vite `resolve.alias` configuration.
- 3
Loaders (ts-loader, babel-loader, style-loader) are removed as Vite handles TypeScript and CSS natively.
- 4
Copy the output to `vite.config.ts` and adjust your root index.html script tag.
