## 🚀 Deployment

### Automatic Deployment (Current Setup)

The project uses **Gitea Actions** for CI/CD. Every push to `main` or `staging` triggers:

1. **Build**: Docker image built for `linux/arm64` with branch-specific build args
2. **Push**: Image pushed to `registry.infra.mintel.me` with commit SHA tag
3. **Deploy**: SSH to production server, pull and restart containers using branch-specific `.env` files

**Workflow**: `.gitea/workflows/deploy.yml`

**Branch Deployments**:

- `main` branch: Deploys to production using `.env.prod`
- `staging` branch: Deploys to staging using `.env.staging`

**Environment Overrides**:
The CI/CD workflow supports `STAGING_`-prefixed secrets (e.g., `STAGING_NEXT_PUBLIC_BASE_URL`) to override default secrets when deploying the `staging` branch.

**Required Secrets** (configure in Gitea repository settings):

- `REGISTRY_USER` - Docker registry username
- `REGISTRY_PASS` - Docker registry password
- `ALPHA_SSH_KEY` - SSH private key for deployment
- `NEXT_PUBLIC_BASE_URL` - Application base URL (e.g., `https://klz-cables.com`)
- `UMAMI_WEBSITE_ID` - Analytics ID
- `UMAMI_API_ENDPOINT` - Analytics API endpoint (formerly NEXT_PUBLIC_UMAMI_SCRIPT_URL)
- `SENTRY_DSN` - Error tracking DSN
- `MAIL_HOST`, `MAIL_PORT`, `MAIL_USERNAME`, `MAIL_PASSWORD`, `MAIL_FROM`, `MAIL_RECIPIENTS` - Email configuration

### Manual Deployment

```bash
# SSH into production server
ssh deploy@alpha.mintel.me

# Navigate to project
cd /home/deploy/sites/klz-cables.com

# Pull latest image and restart
docker compose pull
docker compose up -d --force-recreate --remove-orphans
docker image prune -f
```

Or use the convenience script:

```bash
bash scripts/deploy-webhook.sh
```

### Architecture

```
Client → Traefik (TLS) → Next.js App
```

**Domains**:

- `klz-cables.com` - Production
- `www.klz-cables.com` - Production (www)
- `staging.klz-cables.com` - Staging

**Services**:

- `app`: Next.js application (port 3000)
- `traefik`: Reverse proxy (external)

For detailed deployment documentation, see [`docs/DEPLOYMENT.md`](docs/DEPLOYMENT.md).

## 📈 Performance

### Build Time

- **Target**: < 2 minutes
- **Current**: ~1-2 minutes

### Page Load

- **Target**: < 100ms
- **Current**: Static HTML from CDN

### Bundle Size

- **Target**: < 100KB gzipped
- **Current**: Optimized with code splitting

## 🔒 Security

- Rate limiting (recommended)
- Turnstile CAPTCHA (pending)

## 🎓 WordPress Specifics

### WPBakery Shortcodes Removed

- `[vc_row]`, `[vc_column]`, `[vc_column_text]`
- `[nectar_*]` (Salient theme)
- `[image_with_animation]`
- `[split_line_heading]`
- `[divider]`

### HTML Sanitization

```
https://klz-cables.com/wp-content/uploads/... → /media/...
```

## 🐛 Troubleshooting

### Common Issues

**TypeScript Errors**

- The TypeScript errors shown in the editor are expected
- They occur because modules reference each other
- The build process resolves these correctly
- Run `npm run build` to verify

**Build Failures**

- Check environment variables
- Verify data files exist
- Clear `.next` cache: `rm -rf .next`

**Missing Modules**

- Run `npm install --legacy-peer-deps`
- Check `package.json` dependencies
