## Configuration

### Environment Setup

1. **Development Environment**
   ```bash
   npm run dev
   ```
   - Hot reload enabled
   - Source maps available
   - All modules loaded for development

2. **Production Environment**
   ```bash
   npm run build
   npm run preview
   ```
   - Optimized bundles
   - Minified assets
   - Smart code splitting

### Vite Configuration

The template includes an optimized `vite.config.js` with:

- **Entry Points**: All 42 HTML files configured
- **Code Splitting**: Automatic vendor/app separation
- **Asset Optimization**: Images, fonts, and static files
- **Development Features**: Hot reload, source maps
- **Production Optimizations**: Minification, compression

### SASS Configuration

SASS is configured in `src/main.scss`:

```scss
// Modern @use syntax (recommended)
@use "bootstrap/scss/bootstrap";
@use "./scss/custom.scss";

// Legacy @import syntax (deprecated but still works)
// @import "bootstrap/scss/bootstrap";
// @import "./scss/custom.scss";
```

- Table pages (tables.html, tables_dynamic.html)
- Chart pages (chartjs.html, chartjs2.html, chart3.html)

### Performance Check

Run the optimization analysis:

```bash
npm run optimize
```

This will show you:
- Bundle sizes
- Loading times
- Optimization recommendations

## Troubleshooting

### Common Issues

#### 1. Node.js Version Issues

**Error:** `npm ERR! engine Unsupported engine`

**Solution:** Update Node.js to version 16 or higher:
```bash
# Check current version
node --version

# Update Node.js from https://nodejs.org/
```

#### 2. Port Already in Use

**Error:** `Port 3000 is already in use`

**Solution:** Either stop the conflicting process or use a different port:
```bash
# Use different port
npm run dev -- --port 3001
```

#### 3. SASS Compilation Errors

**Error:** SASS deprecation warnings

**Solution:** These are mainly from Bootstrap internal files and can be safely ignored. Our project code uses modern SASS syntax.

#### 4. Module Not Found

**Error:** `Cannot resolve module`

**Solution:** Clear cache and reinstall:
```bash
# Delete node_modules and package-lock.json
rm -rf node_modules package-lock.json

# Reinstall dependencies
npm install
```

#### 5. Build Failures

**Error:** Build process fails

**Solution:** Check for file permission issues and ensure all dependencies are installed:
```bash
# Clear cache
npm cache clean --force

# Reinstall
npm install

# Try building again
npm run build
```
