    }
  }

  const copyJoinUrl = () => {

Best Practices

Session Management

Clear user feedback - Always show loading states when creating sessions
Error handling - Gracefully handle session creation failures
Session persistence - Consider storing session context for user experience

User Experience

Immediate feedback - Show session status changes instantly
Share functionality - Make it easy to invite others to the session
Visual indicators - Use clear visual cues for session states

Integration Patterns

Combine with other hooks - Use with useIsTogether, useJoinUrl, and useConnectedUsers
State management - Track session metadata in local storage or state
Responsive design - Ensure session creators work on all device sizes

Common Use Cases

Quick Collaboration

Perfect for impromptu collaboration sessions:

const quickCollaborate = () => {
  createRandomSession()
  // Users can immediately start collaborating
}

Game Lobbies

Create instant game rooms:

const createGameRoom = (gameType: string) => {
  localStorage.setItem('gameType', gameType)
  createRandomSession()
}

Study Groups

Start educational sessions:

const startStudySession = (topic: string) => {
  localStorage.setItem('studyTopic', topic)
  createRandomSession()
}

useIsTogether - Check if user is in a session
useJoinUrl - Get the session join URL
useLeaveSession - Leave the current session
useConnectedUsers - See who’s in the session

TypeScript Support

This hook has a simple, type-safe signature:

const createRandomSession: () => void = useCreateRandomSession()

// Usage is straightforward
const handleClick = () => {
  createRandomSession() // Type-safe, no parameters needed
}

The session credentials (name and password) are automatically generated and handled internally. Users don’t need to manage these details when using random sessions.
