confetti-react

This is a fork of react-confetti which was created when that library was unsupported and the latest release was completely broken. It is my understanding that the original library is once again actively maintained. This fork has cleaner builds, but is not as active.

For live examples and demo's of this code, you can reference the react-confetti live documentation.

confetti-react

Confetti without the cleanup.

Based on a pen by @Gthibaud: https://codepen.io/Gthibaud/pen/ENzXbp

Install

npm install confetti-react

Use

width and height props are recommended. They will default to the initial window dimensions, but will not respond to resize events. It is recommended to provide the dimensions yourself. Here is an example using a hook:

import React from 'react';
import useWindowSize from 'react-use/lib/useWindowSize';
import Confetti from 'confetti-react';

export default () => {
  const { width, height } = useWindowSize();
  return <Confetti width={width} height={height} />;
};

Props

Property	Type	Default	Description
width	Number	window.innerWidth || 300	Width of the <canvas> element.
height	Number	window.innerHeight || 200	Height of the <canvas> element.
numberOfPieces	Number	200	Number of confetti pieces at one time.
confettiSource	{ x: Number, y: Number, w: Number, h: Number }	{x: 0, y: 0, w: canvas.width, h:0}	Rectangle where the confetti should spawn. Default is across the top.
friction	Number	0.99
wind	Number	0
gravity	Number	0.1
initialVelocityX	Number	4	How fast confetti is emitted horizontally
initialVelocityY	Number	10	How fast confetti is emitted vertically
colors	String[]	['#f44336' '#e91e63' '#9c27b0' '#673ab7' '#3f51b5' '#2196f3' '#03a9f4' '#00bcd4' '#009688' '#4CAF50' '#8BC34A' '#CDDC39' '#FFEB3B' '#FFC107' '#FF9800' '#FF5722' '#795548']	All available Colors for the confetti pieces.
opacity	Number	1.0
recycle	Bool	true	Keep spawning confetti after numberOfPieces pieces have been shown.
run	Bool	true	Run the animation loop
tweenDuration	Number	5000	How fast the confetti is added
tweenFunction	(currentTime: number, currentValue: number, targetValue: number, duration: number, s?: number) => number	easeInOutQuad	See tween-functions
drawShape	(context: CanvasRenderingContext2D) => void	undefined	See below
onConfettiComplete	(confetti: Confetti) => void	undefined	Called when all confetti has fallen off-canvas.

drawShape()

Draw a custom shape for a particle. If not provided, defaults to a random selection of a square, circle or strip confetto. The function is called with the canvas context as a parameter and the Particle as the this context.

For example, to draw all spirals:

<Confetti
  drawShape={ctx => {
    ctx.beginPath();
    for (let i = 0; i < 22; i++) {
      const angle = 0.35 * i;
      const x = (0.2 + 1.5 * angle) * Math.cos(angle);
      const y = (0.2 + 1.5 * angle) * Math.sin(angle);
      ctx.lineTo(x, y);
    }
    ctx.stroke();
    ctx.closePath();
  }}
