useCursors

Overview

useCursors enables real-time cursor tracking and display in collaborative applications. It automatically captures mouse movements and broadcasts cursor positions to all connected users, making it perfect for collaborative editing, design tools, presentations, and any application where user awareness is important.

Perfect for: Collaborative editors, design tools, presentation software, drawing applications, code editors, interactive dashboards, and any feature requiring real-time user cursor awareness.

Basic Usage

import { useCursors } from 'react-together'

function CursorTracker() {
  const { myCursor, allCursors } = useCursors({ deleteOnLeave: true })

  return (
    <div className="relative w-full h-screen bg-gray-50">
      {/* Render other users' cursors */}
      {Object.entries(allCursors).map(([userId, cursor]) => {
        if (!cursor) return null
        
        return (
          <div
            key={userId}
            className="fixed w-3 h-3 bg-blue-500 rounded-full pointer-events-none z-50"
            style={{
              left: cursor.pageX,
              top: cursor.pageY,
              transform: 'translate(-50%, -50%)',
              transition: 'all 0.1s linear',
            }}
          />
        )
      })}
      
      {/* Display current user's cursor position */}
      <div className="absolute top-4 left-4 bg-white p-4 rounded shadow">
        {myCursor ? (
          <p>Your cursor: {myCursor.pageX}, {myCursor.pageY}</p>
        ) : (
          <p>Move your cursor to share your position</p>
        )}
        <p>Active cursors: {Object.keys(allCursors).length}</p>
      </div>
    </div>
  )
}

Best Practices

Performance Optimization

// Adjust throttle delay based on use case
const { myCursor, allCursors } = useCursors({
  throttleDelay: 16,  // 60fps for smooth gaming/design
  throttleDelay: 50,  // 20fps for general use (default)
  throttleDelay: 100, // 10fps for text editing
})

// Use deleteOnLeave for better UX
const { myCursor, allCursors } = useCursors({
  deleteOnLeave: true, // Remove cursor when mouse leaves window
})

Cursor Visualization

// Smooth cursor transitions
<div
  style={{
    left: cursor.clientX,
    top: cursor.clientY,
    transition: 'all 0.1s linear', // Smooth movement
  }}
/>

// Custom cursor shapes based on tools/modes
const CursorIcon = ({ tool }: { tool: string }) => {
  switch (tool) {
    case 'pen':
      return <PenIcon />
    case 'eraser':
      return <EraserIcon />
    default:
      return <DefaultCursorIcon />
  }
}

Coordinate Systems

// Use appropriate coordinates for your use case
const cursor = allCursors[userId]

// For fixed positioning relative to viewport
style={{ left: cursor.clientX, top: cursor.clientY }}

// For absolute positioning relative to document
style={{ left: cursor.pageX, top: cursor.pageY }}

// For responsive layouts using percentages
style={{ 
  left: `${cursor.percentX}%`, 
  top: `${cursor.percentY}%` 
}}

useNicknames - Display user names with cursors
useConnectedUsers - Get connected user information
useStateTogetherWithPerUserValues - Share per-user data
useHoveringUsers - Track hover interactions

TypeScript Support

The hook provides full TypeScript support with detailed interfaces:

interface Cursor {
  clientX: number    // Viewport coordinates
  clientY: number
  pageX: number      // Document coordinates  
  pageY: number
  percentX: number   // Percentage coordinates
  percentY: number
}

interface UseCursorsOptions {
  deleteOnLeave?: boolean    // default: false
  omitMyValue?: boolean      // default: true  
  throttleDelay?: number     // default: 50
}

const {
  myCursor,    // Cursor | null
  allCursors   // Record<string, Cursor>
} = useCursors(options)
