Resolve Port Conflicts

FIX port conflicts when development server won't start or tests fail. Manage port 5546 for PomoFlow, kill existing processes, and resolve server startup issues. Use when npm run dev fails, port is in use, or server won't start.

Port Manager

Instructions

Primary Port Configuration

  • Main Application: Port 5546 (NEVER change)
  • Storybook: Port 6006 (separate from main app)
  • Development Server: Always use npm run dev

Server Commands

# Start main application (port 5546)
npm run dev

# Start Storybook (port 6006)
npm run storybook

# Check if server is running
curl http://localhost:5546

Port Conflict Resolution

# Kill processes using port 5546
lsof -ti:5546 | xargs kill -9

# Or use pkill for node processes
pkill -f "vite.*5546"

# Restart server
npm run dev

Development URLs

  • Main Application: http://localhost:5546
  • Storybook: http://localhost:6006
  • Design System: http://localhost:5546/#/design-system

Browser Access Patterns

Always reference the application using:

  • http://localhost:5546 for main app
  • http://localhost:6006 for Storybook
  • Never hardcode other ports

Server Health Check

const checkServerHealth = async () => {
  try {
    const response = await fetch('http://localhost:5546')
    return response.ok
  } catch (error) {
    console.error('Server not accessible on port 5546:', error)
    return false
  }
}

Testing Environment Setup

# Ensure server is running before tests
npm run dev &
sleep 5  # Wait for server to start
npm run test

This skill ensures consistent use of port 5546 and proper server management for the productivity application.
