## Building for Production

Before deploying, build your site for production.

### Build Command

```bash
# Basic build
hugo

# Build with minification
hugo --minify

# Build with specific environment
hugo --environment production
```

### Build Output

The build creates a `public/` directory containing:
```
public/
├── index.html
├── css/
│   └── main.min.[hash].css
├── js/
│   └── main.min.[hash].js
├── images/
├── blog/
├── docs/
└── ...
```

### Pre-Deployment Checklist

- [ ] Update `baseURL` in `hugo.toml` to production URL
- [ ] Remove draft posts (`draft: false` or remove drafts)
- [ ] Test build locally: `hugo && hugo server -s public`
- [ ] Verify all links work
- [ ] Check image paths and assets
- [ ] Test responsive design
- [ ] Validate HTML/CSS
- [ ] Check analytics integration
- [ ] Review SEO meta tags
- [ ] Test performance with Lighthouse

### Environment Configuration

**Development**:
```toml
# hugo.toml
baseURL = "http://localhost:1313/"
```

**Production** (update before deploying):
```toml
# hugo.toml
baseURL = "https://yourdomain.com/"
```

### AWS S3 + CloudFront

Enterprise-grade hosting with AWS infrastructure.

#### S3 Setup

1. **Create S3 Bucket**:
```bash

```

2. **Enable Static Website Hosting**:
```bash
aws s3 website s3://your-bucket-name \
  --index-document index.html \
  --error-document 404.html
```

3. **Set Bucket Policy**:

Create `bucket-policy.json`:
```json
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "PublicReadGetObject",
      "Effect": "Allow",
      "Principal": "*",
      "Action": "s3:GetObject",
      "Resource": "arn:aws:s3:::your-bucket-name/*"
    }
  ]
}
```

```bash
aws s3api put-bucket-policy \
  --bucket your-bucket-name \
  --policy file://bucket-policy.json
```

4. **Deploy Site**:
```bash
hugo --minify
aws s3 sync public/ s3://your-bucket-name --delete
```

#### CloudFront Setup

1. **Create Distribution**:
   - Origin: Your S3 bucket
   - Viewer protocol: Redirect HTTP to HTTPS
   - Price class: Choose based on needs
   - Alternate domain names: your-domain.com
   - SSL certificate: Request from ACM

2. **Configure DNS**:
   - Add CNAME record pointing to CloudFront distribution

3. **Invalidate Cache After Deployment**:
```bash
aws cloudfront create-invalidation \
  --distribution-id YOUR_DISTRIBUTION_ID \
  --paths "/*"
```

#### Deployment Script

Create `deploy.sh`:

```bash
#!/bin/bash

# Build site
echo "Building site..."
hugo --minify

# Sync to S3
echo "Uploading to S3..."
aws s3 sync public/ s3://your-bucket-name \
  --delete \
  --cache-control "max-age=3600"

# Invalidate CloudFront cache
echo "Invalidating CloudFront cache..."
aws cloudfront create-invalidation \
  --distribution-id YOUR_DISTRIBUTION_ID \
  --paths "/*"

echo "Deployment complete!"
```

Make executable:
```bash
chmod +x deploy.sh
./deploy.sh
```

## Custom Server Deployment

    server_name yourdomain.com www.yourdomain.com;

    ssl_certificate /path/to/cert.pem;
    ssl_certificate_key /path/to/key.pem;

    root /var/www/html;
    index index.html;

    location / {
        try_files $uri $uri/ =404;
    }

    # Cache static assets
    location ~* \.(jpg|jpeg|png|gif|ico|css|js|svg|woff|woff2)$ {

}
```

4. **Enable Site**:
```bash

## Environment Variables

### Common Variables

```bash
# Hugo version
HUGO_VERSION=0.120.0

# Environment
HUGO_ENV=production

# Enable Git info
HUGO_ENABLEGITINFO=true

# Google Analytics
HUGO_GOOGLE_ANALYTICS=G-XXXXXXXXXX

# Google Tag Manager

## Performance Optimization

### Build Optimization

1. **Minify Output**:
```bash
hugo --minify
```

2. **Enable Caching**:
```toml
[caches]
  [caches.images]
    dir = ":resourceDir/_gen"
    maxAge = "1440h"
```

3. **Optimize Images**:
   - Compress before uploading
   - Use WebP format
   - Implement lazy loading

### CDN Configuration

**Cache Headers**:
```nginx
# Static assets - 1 year
location ~* \.(jpg|png|css|js|woff2)$ {
    expires 1y;
    add_header Cache-Control "public, immutable";
}

# HTML - short cache
location ~* \.html$ {
    expires 1h;
    add_header Cache-Control "public, must-revalidate";
}
```

### Compression

Enable gzip/brotli compression on server or CDN.

**Nginx**:
```nginx
gzip on;
gzip_types text/plain text/css application/json application/javascript;
gzip_min_length 1000;
```

### Performance Checklist

- [ ] Enable minification
- [ ] Optimize images (compress, WebP)
- [ ] Use CDN for static assets
- [ ] Enable HTTP/2
- [ ] Configure caching headers
- [ ] Enable gzip/brotli compression
- [ ] Lazy load images
- [ ] Minimize CSS/JS
- [ ] Use resource hints (preload, prefetch)
- [ ] Test with Lighthouse/PageSpeed

2. **Test Navigation**: Click through all pages
3. **Verify Assets**: Images, CSS, JS loading
4. **Check Forms**: Test contact/signup forms
5. **Test Mobile**: Responsive design working
6. **Check Analytics**: Tracking installed correctly
7. **SSL Certificate**: HTTPS working
8. **Performance**: Run Lighthouse audit

### Monitoring

- **Uptime Monitoring**: UptimeRobot, Pingdom
- **Analytics**: Google Analytics, Plausible
- **Error Tracking**: Sentry, Rollbar
- **Performance**: Lighthouse CI, SpeedCurve

### Maintenance

1. **Regular Updates**: Keep Hugo and dependencies updated
2. **Content Review**: Update outdated content
3. **Backup**: Regular backups of content and config
4. **Security**: Monitor for vulnerabilities
5. **Performance**: Regular performance audits

## Troubleshooting Deployment

### Build Fails

**Problem**: Build fails with errors

**Solutions**:
- Check Hugo version matches local
- Verify all dependencies installed
- Check for syntax errors in config
- Review build logs for specific errors

### Assets Not Loading

**Problem**: CSS/JS/Images not loading

**Solutions**:
- Verify `baseURL` is correct
- Check asset paths are absolute (`/images/...`)
- Clear browser cache
- Check CDN/server configuration

### 404 Errors

**Problem**: Pages return 404

**Solutions**:
- Verify content files exist
- Check front matter is correct
- Ensure `draft: false`
- Check URL structure

### Slow Build Times

**Problem**: Builds taking too long

**Solutions**:
- Enable caching
- Optimize images before build
- Remove unused content
- Check for infinite loops in templates
