Step 1: Install Vite

Add Vite and framework plugin.

npm install -D vite @vitejs/plugin-react && npm uninstall webpack webpack-cli webpack-dev-server
Step 2: Create vite.config.ts

Minimal config. Most things work out of the box.

import { defineConfig } from 'vite'
import react from '@vitejs/plugin-react'
export default defineConfig({ plugins: [react()] })
Step 3: Update index.html

Move index.html to project root (not public/). Add <script type="module" src="/src/main.tsx">.

Step 4: Fix imports

Vite requires file extensions for non-JS imports. Replace require() with import. Fix process.env → import.meta.env.

Step 5: Replace webpack plugins

html-webpack-plugin → not needed. copy-webpack-plugin → vite-plugin-static-copy. define-plugin → define in vite.config.

Step 6: Update scripts

package.json: dev → vite, build → vite build, preview → vite preview.
