Cursor Burn

Cursor Burn is a React component that creates an interactive fire effect following the mouse cursor. The effect features a unique elastic, gooey animation that makes the fire particles blend smoothly, creating a liquid-like appearance.

Features

• Smooth particle animation with elastic behavior
• Real-time mouse tracking
• Customizable colors, sizes, and behaviors
• Responsive design
• TypeScript support
• Zero dependencies

Installation

npm install cursorburn
# or
yarn add cursorburn

Basic Usage

import CursorBurn from 'cursorburn';

function App() {
  return (
    <div style={{ width: '100vw', height: '100vh', background: 'black' }}>
      <CursorBurn
        colors={["orange", "red", "yellow"]}
        particleSpread={20}
        particleAngleSpread={60}
        particleUpwardForce={0.8}
      />
    </div>
  );
}
