UPN CLI (upncli)

A command-line interface for managing UPN (Updateable Node.js) containers with rich terminal UI, emoji status indicators, and smart deployment features.

Installation

cd cli
npm install
npm link  # Makes 'upncli' available globally

Quick Start

1. Setup a project:

   upncli setup my-app

2. Deploy your application:

   upncli deploy my-app

3. Stream logs:

   upncli logs my-app --follow

Commands

upncli setup <appFolder>

Interactive configuration setup for a project.

Features:

• ✅ Configure server URL
• 🔑 Set bearer token authentication
• 📤 Manage upload blacklist patterns
• 🧪 Test server connection

Example:

upncli setup my-node-app

upncli deploy <appFolder>

Deploy application to UPN server with smart packaging.

Features:

• 📦 Auto-detects and validates app folder
• 🚫 Applies blacklist patterns for optimized packages
• 📊 Real-time upload progress with emoji indicators
• ✅ Automatic server connection testing
• 🔄 Zero-downtime deployment

Options:

• -f, --force - Force deployment without confirmation

Example:

upncli deploy my-node-app
upncli deploy my-node-app --force

upncli logs <appFolder>

View and stream application logs with syntax highlighting.

Features:

• 🎨 Syntax highlighting for different log levels
• 🔄 Auto-reconnect on connection loss
• 🔍 Log filtering capabilities
• ⏱️ Real-time streaming

Options:

• -f, --follow - Follow log output with auto-reconnect
• --filter <pattern> - Filter logs by pattern

Examples:

upncli logs my-app                    # View recent logs
upncli logs my-app --follow           # Stream logs with auto-reconnect
upncli logs my-app --filter "error"   # Filter for error messages

upncli project [action] [name]

Manage multiple projects and configurations.

Actions:

• list - List all configured projects
• setup [name] - Setup a new project configuration
• status [name] - Show detailed project status
• remove [name] - Remove project configuration

Examples:

upncli project list                   # List all projects
upncli project setup admin-dashboard # Setup specific project
upncli project status my-app         # Check project status
upncli project remove old-app        # Remove project config

Aliases

• upncli ls - Alias for project list
• upncli status [name] - Alias for project status

Configuration

Global Configuration

Configuration is stored in ~/.upncli/config.json:

{
  "projects": {
    "my-app": {
      "serverUrl": "http://localhost:3888",
      "bearerToken": "your-secret-token",
      "blacklist": ["node_modules", ".git", "*.log", "dist"]
    },
    "admin-dashboard": {
      "serverUrl": "https://admin.example.com",
      "bearerToken": null,
      "blacklist": ["node_modules", ".git"]
    }
  }
}

Per-Project Settings

Each project can have:

• Server URL: Target UPN server endpoint
• Bearer Token: Authentication token (optional)
• Blacklist Patterns: Files/folders to exclude from deployment

Blacklist Patterns

Supports glob patterns for flexible exclusions:

• node_modules - Exclude node_modules folder
• *.log - Exclude all log files
• dist/** - Exclude entire dist directory
• .env* - Exclude environment files

Status Indicators

The CLI uses emoji indicators for clear visual feedback:

• ✅ Success - Operation completed successfully
• ❌ Error - Operation failed
• ⚠️ Warning - Operation completed with warnings
• ℹ️ Info - Informational message
• ⏳ Loading - Operation in progress
• 📤 Uploading - File upload in progress
• 🚀 Deployment - Deployment operations
• ⚙️ Configuration - Setup and config operations

Deployment Workflow

1. Validation: Checks app folder exists and project is configured
2. Connection Test: Verifies server connectivity
3. Package Creation: Creates optimized zip with blacklist exclusions
4. Upload: Uploads with real-time progress tracking
5. Deployment: Server extracts and starts the application
6. Verification: Confirms deployment success

Error Handling

The CLI provides detailed error messages with helpful suggestions:

❌ Cannot connect to server: ECONNREFUSED
Suggestions:
  ℹ️ Check if the server is running
  ℹ️ Verify the server URL is correct
  ℹ️ Check your network connection

Advanced Features

Auto-Reconnect Logs

When using --follow, the CLI automatically reconnects if the connection is lost:

upncli logs my-app --follow
# Automatically reconnects up to 5 times on disconnection

Smart Package Optimization

The CLI creates optimized deployment packages by:

• Excluding development dependencies
• Applying user-defined blacklist patterns
• Using maximum compression
• Validating package integrity

Multi-Project Management

Easily switch between different projects and environments:

upncli project list
  📁 my-app (active) - http://localhost:3888
  📁 admin-dashboard - https://admin.example.com
  📁 api-server - http://api.local:3000

Troubleshooting

Common Issues

1. Authentication Errors

   upncli setup my-app  # Reconfigure bearer token

2. Connection Issues

   upncli project status my-app  # Test connectivity

3. Large Package Uploads

   • Review blacklist patterns to exclude unnecessary files
   • Check network stability for large uploads

Debug Mode

For detailed debugging, check the server logs or use verbose npm logging:

DEBUG=* upncli deploy my-app

Dependencies

• commander - CLI framework
• inquirer - Interactive prompts
• chalk - Terminal styling
• archiver - Zip creation
• axios - HTTP requests
• ws - WebSocket for logs
• boxen - Text boxes
• cli-progress - Progress bars
