## Production Build

Before deploying, you need to create an optimized production build.

### Quick Build

```bash
npm run build
```

This creates an optimized, minified production build in the `dist/` directory.

## Build Commands

### Standard Production Build

```bash
npm run build
```

**Features:**
- Minified JavaScript and CSS
- Optimized assets
- Source maps disabled
- Production environment variables
- Compressed bundle sizes

### Minified Build

```bash
npm run release:minified
```

**Use case:** Maximum optimization for production deployment

**Features:**
- Aggressive minification
- Tree shaking
- Dead code elimination
- Smallest possible bundle size

### Unminified Build

```bash
npm run release:unminified
```

**Use case:** Debugging production issues

**Features:**
- Readable code
- No minification
- Easier to debug
- Larger file sizes

### Clean Build

```bash
# Clean and rebuild
npm run clean
npm run build
```

Removes the `dist/` directory before building to ensure a fresh build.

## Build Output

After running the build command, the `dist/` directory contains:

```
dist/
├── index.html              # Main dashboard page
├── 404.html                # Error pages
├── 500.html
├── signin.html             # Authentication pages
├── signup.html
├── email.html              # Application pages
├── compose.html
├── chat.html
├── calendar.html
├── charts.html
├── forms.html
├── buttons.html
├── ui.html
├── basic-table.html
├── datatable.html
├── google-maps.html
├── vector-maps.html
├── blank.html
└── assets/
    ├── bundle.[hash].js    # Compiled JavaScript
    ├── styles.[hash].css   # Compiled CSS
    └── static/             # Images, fonts, etc.
        ├── fonts/
        └── images/
```

### File Hashing

Production builds include content hashes in filenames (e.g., `bundle.a1b2c3d4.js`) for:
- Cache busting
- Long-term caching
- Version control

## Build Optimization

### Automatic Optimizations

The build process automatically applies:

1. **JavaScript Optimization**
   - Minification with Terser
   - Tree shaking (removes unused code)
   - Code splitting
   - ES6+ transpilation to ES5

2. **CSS Optimization**
   - Minification with CSS Minimizer
   - Autoprefixer for browser compatibility
   - Unused CSS removal
   - Critical CSS inlining (optional)

3. **Asset Optimization**
   - Image compression
   - Font subsetting
   - SVG optimization
   - Asset hashing

4. **Bundle Optimization**
   - Gzip compression ready
   - Brotli compression ready
   - Chunk splitting
   - Lazy loading support

### Bundle Size Analysis

To analyze your bundle size:

```bash
# Install webpack-bundle-analyzer
npm install --save-dev webpack-bundle-analyzer

# Add to webpack config and rebuild
npm run build
```

## Environment Configuration

### Environment Variables

Create environment-specific configurations:

**Development (.env.development):**
```env
NODE_ENV=development
API_URL=http://localhost:3000
DEBUG=true
```

**Production (.env.production):**
```env
NODE_ENV=production
API_URL=https://api.yourdomain.com
DEBUG=false
```

### Using Environment Variables

In your JavaScript:
```javascript
const apiUrl = process.env.API_URL || 'http://localhost:3000';
const isProduction = process.env.NODE_ENV === 'production';
```

npm run clean
rm -rf node_modules package-lock.json
npm install
npm run build
```

### Assets Not Loading

- Check file paths are relative
- Verify assets are in `dist/` folder
- Check server configuration
- Verify CORS settings

### Blank Page After Deployment

- Check browser console for errors
- Verify all files uploaded
- Check base URL configuration
- Verify server routing for SPA

### Styles Not Applied

## Performance Optimization

### Enable Compression

Most hosting platforms enable Gzip/Brotli automatically. Verify:

```bash
# Check if Gzip is enabled
curl -H "Accept-Encoding: gzip" -I https://your-domain.com
```

### CDN Configuration

Use a CDN for faster global delivery:
- Cloudflare
- AWS CloudFront
- Fastly
- KeyCDN

### Caching Strategy

Set appropriate cache headers:
- HTML: No cache or short cache
- CSS/JS: Long cache (1 year) with hashing
- Images: Long cache (1 year)
- Fonts: Long cache (1 year)

## Continuous Deployment

    - name: Deploy to Netlify
      uses: netlify/actions/cli@master
      env:
        NETLIFY_AUTH_TOKEN: ${{ secrets.NETLIFY_AUTH_TOKEN }}
        NETLIFY_SITE_ID: ${{ secrets.NETLIFY_SITE_ID }}
