react-confetti

Confetti without the cleanup. Demo

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

Install

npm install react-confetti

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 'react-confetti'

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 \| { min: Number, max: Number }`	4	Range of values between which confetti is emitted horizontally, positive numbers being rightward, and negative numbers being leftward. Giving a number `x` is equivalent to giving a range `{ min: -x, max: x }`.
`initialVelocityY`	`Number \| { min: Number, max: Number }`	10	Range of values between which confetti is emitted vertically, positive numbers being downward, and negative numbers being upward. Giving a number `y` is equivalent to giving a range `{ min: -y, max: 0 }`.
`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()
  }}
/>
