How do I set up environment and create first project?

# Step 1: Prerequisites and Scaffolding Ensure Node.js version 20.19+ or 22.12+ is installed (download from [nodejs.org](https://nodejs.org/)). Create a new Vite project: ```bash npm create vite@latest my-vite-app -- --template vanilla cd my-vite-app npm install npm run dev ``` Open http://localhost:5173 to see 'Hello Vite!'. This scaffolds a vanilla JS project with instant dev server.

How do I explore dev server and hot module replacement?

# Step 2: Hands-On with HMR and Features Edit `index.html` or `src/main.js` to add content, e.g.: ```js // src/main.js document.querySelector('#app').innerHTML = `\n Hello Vite!\n Count: 0 \n`; ``` Add CSS in `counter.js` and import it. Watch live updates without reload. Import assets: `import './style.css'; import viteLogo from '/vite.svg';` Test TypeScript by switching to `vanilla-ts` template.

How do I configure vite and add plugins?

# Step 3: Customization with vite.config.js Create `vite.config.js`: ```js import { defineConfig } from 'vite'; export default defineConfig({ base: '/my-app/', plugins: [], server: { port: 3000 }, }); ``` Install and add plugins, e.g. for legacy browsers: ```bash npm install -D @vitejs/plugin-legacy ``` ```js // vite.config.js import legacy from '@vitejs/plugin-legacy'; plugins: [legacy()] ``` Explore CSS preprocessors: `npm install -D sass` and use `.scss`.

How do I build and optimize for production?

# Step 4: Production Builds Run: ```bash npm run build # Outputs to dist/ npm run preview # Serves dist/ at localhost:4173 ``` Inspect `dist/` for optimized bundles, CSS splitting. Tweak build in config: ```js build: { target: 'es2015', minify: 'terser', } ``` Test responsive assets and code splitting.

How do I integrate framework and deploy?

# Step 5: Framework Scaffolds and Deployment Scaffold React/Vue: ```bash npm create vite@latest my-react-app -- --template react cd my-react-app npm install npm run dev ``` Deploy to Netlify/Vercel: 1. `npm run build` 2. Use CLI: `npm i -g vercel && vercel` or drag `dist/` to Netlify. For GitHub Pages, set `base: '/repo-name/'` and add workflow.

Common Mistakes to Avoid

❌ Using outdated Node.js version

→Upgrade to Node.js 20.19+ and verify with `node -v`

❌ Skipping `npm install` after scaffolding
