Install

You can install library from NPM using yarn or npm

yarn add js-confetti

Alternatively you can download script from CDN

and then access JSConfetti global variable

Usage

Initialize instance of JSConfetti class and call addConfetti method

import JSConfetti from 'js-confetti'

const jsConfetti = new JSConfetti()

jsConfetti.addConfetti()

NOTE new JSConfetti() creates HTML Canvas element and adds it to page, so call it only once!

If need to use custom canvas element, you can pass canvas arg to JSConfetti constructor (example)

const canvas = document.getElementById('your_custom_canvas_id')

const jsConfetti = new JSConfetti({ canvas })

Customise confetti

Use emojis as confetti:

jsConfetti.addConfetti({
   emojis: ['', '⚡️', '', '✨', '', ''],
})

Customize confetti colors:

jsConfetti.addConfetti({
  confettiColors: [
    '#ff0a54', '#ff477e', '#ff7096', '#ff85a1', '#fbb1bd', '#f9bec7',
  ],
})

Customize confetti radius:

jsConfetti.addConfetti({
  confettiRadius: 6,
})

Customize confetti number:

jsConfetti.addConfetti({
  confettiRadius: 6,
  confettiNumber: 500,
})

Combine different properties:

jsConfetti.addConfetti({
  emojis: [''],
  emojiSize: 100,
  confettiNumber: 30,
})

addConfettiAtPosition

example with dispatching confetti on mouse click - take X and Y position of the mouse from event and pass them in confettiDispatchPosition param.

all customisations work in this method as well!

jsConfettiRef.addConfettiAtPosition({
  confettiDispatchPosition: {
    x: event.clientX,
    y: event.clientY
  }
})

clearCanvas()

Call clearCanvas method to clear canvas

Example:

const jsConfetti = new JSConfetti()

jsConfetti.addConfetti()

// ... 
jsConfetti.clearCanvas()

addConfetti Promise

addConfetti method returns Promise, which is resolved when added confetti dissapears from the user screen due to the gravity physics of confetti

Example:

// async/await
await jsConfetti.addConfetti()
console.log('Confetti animation completed!')

// Promise.then
jsConfetti.addConfetti()
   .then(() => console.log('Confetti animation completed!'))
