vscode-sftp-config（VS Code sftp 配置）

VSCode SFTP Configuration

Configure VSCode SFTP for deploying static websites to production servers. Provides complete workflow including production-ready Nginx configuration templates with security headers, caching strategies, and performance optimizations.

Core Workflow

Step 1: Analyze Project Structure

Identify the static files to deploy:

• Pure static projects: HTML, CSS, JS in root directory
• Build-based projects: Look for dist/, build/, or public/ output directories
• Static generators: Check for build commands in package.json or documentation

Ask the user for deployment details:

1. Remote server address (IP or hostname)
2. Remote path (e.g., /var/www/sitename)
3. SSH authentication method (password or SSH key path)
4. Domain name(s) for Nginx configuration
5. Whether this is a main domain or subdomain

Step 2: Generate SFTP Configuration

VSCode Extension: This skill uses the code-sftp extension by Satiro Marra.

Step 2A: Configure SSH Config (Recommended Best Practice)

Before creating sftp.json, set up SSH host alias in ~/.ssh/config for better management:

Host project-prod
    HostName 82.157.29.215
    User root
    Port 22
    IdentityFile ~/.ssh/id_rsa
    IdentitiesOnly yes
    ServerAliveInterval 60
    ServerAliveCountMax 3

Benefits of SSH config:

• ✅ Eliminates SFTP extension warnings (Section for 'IP' not found)
• ✅ Use host alias in terminal: ssh project-prod
• ✅ Centralized SSH settings (connection keep-alive, compression, etc.)
• ✅ Easier to manage multiple environments (dev, staging, prod)

Check if ~/.ssh/config already has the server:

cat ~/.ssh/config | grep -A 5 "82.157.29.215"

If found, use that existing host alias. If not, add a new entry.

Step 2B: Create SFTP Configuration

Create .vscode/sftp.json using the template from assets/sftp.json.template.

Essential configuration fields:

• name: Profile name for easy identification
• host: SSH host alias (e.g., "Tencent_Pro") or IP address
• protocol: "sftp" for SFTP (secure) or "ftp" for FTP
• port: 22 for SFTP, 21 for FTP
• username: SSH/FTP username
• privateKeyPath: Path to SSH private key (e.g., /Users/username/.ssh/id_rsa)
• remotePath: Remote directory path (e.g., /var/www/sitename)
• uploadOnSave: false recommended (manual sync is safer)

Optional advanced fields:

• ignore: Array of files/folders to exclude from upload
• watcher: File watching configuration for auto-upload
• syncOption: Sync behavior (delete, update, skip existing files)
• useTempFile: Use temporary files during upload
• downloadOnOpen: Auto-download files when opened

Customize for the project:

• Replace {{HOST_ALIAS}} with SSH config alias (recommended) or IP address
• Replace other {{PLACEHOLDERS}} with actual values
• Add project-specific files to ignore array (.claude, nginx.conf, build artifacts, etc.)
• For build-based projects: Keep uploadOnSave: false, sync manually after build
• For pure static projects: Optionally enable uploadOnSave: true for instant deployment

Step 3: Generate Nginx Configuration

Choose the appropriate template:

• Main domain: Use assets/nginx-static.conf.template for primary website
• Subdomain: Use assets/nginx-subdomain.conf.template for subdomains like slides.example.com

Customize the configuration:

1. Replace {{DOMAIN}} with actual domain name
2. Replace {{DOCUMENT_ROOT}} with remote path (e.g., /var/www/aiseed)
3. Adjust SSL certificate paths if using custom certificates
4. Configure subdomain-specific settings if needed

Include essential features from references/nginx-best-practices.md:

• HTTP → HTTPS redirect
• HTTP/2 support
• Gzip compression
• Static resource caching (1 year for JS/CSS/images, 1 hour for HTML)
• Security headers (HSTS, X-Frame-Options, CSP, etc.)
• Access and error logs

Step 4: Provide Deployment Instructions

Generate a deployment checklist based on assets/deploy-checklist.md:

1. Initial setup (one-time):

- Install VSCode extension: code-sftp by Satiro Marra - Open Command Palette (Cmd/Ctrl+Shift+P) → SFTP: Config to create .vscode/sftp.json - Verify SSH access to server: ssh user@host - Ensure remote directory exists: ssh user@host "mkdir -p /var/www/sitename" - Set proper permissions: ssh user@host "chmod 755 /var/www/sitename"

1. File deployment:

- For build projects: Run build command first (e.g., npm run build) - Open VSCode Command Palette → SFTP: Sync Local → Remote to upload all files - Or right-click folder in Explorer → "Upload Folder" - Monitor upload progress in VSCode Output panel (View → Output → SFTP) - Verify files uploaded: ssh user@host "ls -la /var/www/sitename"

1. Nginx configuration:

- Upload generated config to /etc/nginx/sites-available/ - Create symlink: ln -s /etc/nginx/sites-available/site.conf /etc/nginx/sites-enabled/ - Test config: sudo nginx -t - Reload: sudo systemctl reload nginx

1. SSL/TLS setup (if not configured):

- Refer to references/ssl-security.md for certificate setup - Use Let's Encrypt for free certificates: certbot --nginx -d example.com

1. Verification:

- Test HTTPS: curl -I https://example.com - Check security headers: Use securityheaders.com - Test performance: Use PageSpeed Insights

Step 5: Document the Setup

Update project documentation (README.md or CLAUDE.md) with:

• Deployment method (SFTP to /var/www/path)
• SFTP configuration location (.vscode/sftp.json)
• Nginx configuration reference
• Build commands (if applicable)
• Deployment workflow for future updates

Benefits of This Architecture

Explain to users why static + SFTP deployment is advantageous:

1. Simplicity: Edit → Upload → Live (no build pipelines, no containers)
2. Performance: Nginx serves static files faster than Node.js/Python backends
3. Reliability: No backend processes to crash or hang
4. Resource efficiency: Lower server memory and CPU usage
5. Cost effective: Can host on minimal VPS or shared hosting
6. Easy rollback: Copy previous version from backup directory

When NOT to Use This Architecture

Static + SFTP deployment is not appropriate when:

• Backend API endpoints are required
• Server-side form processing is needed (unless using external services like n8n, FormSpree)
• User authentication/sessions are required
• Database interactions are needed
• Server-side rendering (SSR) is required
