spawn-confetti

🎉 Confetti Effect

A lightweight and highly configurable JavaScript library that spawns confetti on demand—perfect for adding celebration effects to buttons, clicks, or custom triggers on your website.

🚀 Installation:

Option 1: via npm

npm  install  spawn-confetti

Option 2: Vanilla JS

• Download confetti.js and add it to your project folder
• Include it in your HTML as a module:

<script  src="path/to/confetti.js"  type="module"></script>

🎮 Usage and Configuration

Function Arguments:

The spawnConfetti() function has the following arguments:

• amount(number) – Number of confetti particles to spawn. Default: 30

• x, y(number | string) – Spawn coordinates.
  Default: mouse coordinates
  Accepted string values:

  • mouse – spawn at mouse coordinate
  • center – spawn at center coordinate of page
  • max – spawn at max coordinate of page

• velXRange, velYRange(array) – Initial velocity range.
  Default: [-5, 5], [-8, 0]

• angVelXRange, angVelZRange(array) – Constant rotational velocity range.
  Default: [0, 0], [6, 12]

• lifetime(number) – Lifetime of particles in milliseconds.
  Default: 2000

Example:

// Spawn 30 confetti particles at the current mouse position
	spawnConfetti();

// Custom configuration
	spawnConfetti({
		amount: 75,
		x: 'center',
		y: 'max',
		velXRange: [-20, 20],
		velYRange: [-10, -3],
		angVelXRange: [1, 0],
		angVelZRange: [5, 15],
		lifetime: 500
	});

Global Configuration:

There are a few global configurations that you can modify:

• acceleration(vector) – Controls gravity direction.
  Default: (0, 0.25) ➜ To edit values, assign like: acceleration.x = ..., acceleration.y = ...
• maxVel(vector) – Sets maximum velocity.
  Default: (1.5, 10) ➜ To edit values, assign like: maxVel.x = ..., maxVel.y = ...
• drag(vector) – Affects air resistance. Lower values = more drag.
  Default: (0.98, 1), must be ≤ 1 ➜ To edit values, assign like: drag.x = ..., drag.y = ...
• colors(array) – List of colors to randomly assign to particles.
  Default: #f44a4a, #fb8f23, #fee440, #7aff60, #00f5d4, #00bbf9, #9b5de5, #f15bb5
• shapes(array of svg strings) – Shapes for particles to randomly select from.
  Default:

  <rect x="5" y="0" width="6" height="16"/>,
  <path width="16" height="16" d="M0,12 Q4,4 8,12 Q12,20 16,12" stroke-width="5" fill="none"/>,
  <circle cx="9" cy="9" r="5.5"/>,
  <polygon points="9,2.072 17,15.928 1,15.928"/>
  

  ❗ Note: When adding new custom SVG shapes, ensure that any <path> elements include fill="none" to render correctly.
