Installing

pnpm add @neoconfetti/vanilla

# npm
npm install @neoconfetti/vanilla

# yarn
yarn add @neoconfetti/vanilla

Usage

Basic usage

import { Confetti } from '@neoconfetti/vanilla';

const confetti = new Confetti(document.querySelector('#confetti'));

// Explode the confetti
confetti.explode();

With options

import { Confetti } from '@neoconfetti/vanilla';

const confetti = new Confetti(document.querySelector('#confetti'), {
	color: ['#ff0000', '#00ff00', '#0000ff'],
	force: 0.9,
});

confetti.explode();

Defining options elsewhere with typescript

import { type ConfettiOptions, Confetti } from '@neoconfetti/vanilla';

const options: ConfettiOptions = {
	color: ['#ff0000', '#00ff00', '#0000ff'],
	force: 0.9,
};

const confetti = new Confetti(document.querySelector('#confetti'), options);
confetti.explode();

Update options:

import { Confetti } from '@neoconfetti/vanilla';

const confetti = new Confetti(document.querySelector('#confetti'), {
	color: ['#ff0000', '#00ff00', '#0000ff'],
	force: 0.9,
});

// Update the specific options. Will be merged with the existing options.
confetti.options.colors = ['white', 'black'];

// Completely overrides existing options, in this case, the `force` property is set to its default value.
confetti.options = { colors: ['white', 'black'] };

Destroy:

You must destroy the confetti once its not needed

confetti.destroy();

Waiting for confetti to finish:

// confetti.explode() returns a promise that resolves when the confetti is done exploding. You can use this to wait for the confetti to finish exploding before doing something else.
await confetti.explode();

Props

There's tons of options available for this package. All of them are already documented within the code itself, so you'll never have to leave the code editor.

particleCount

Number of confetti particles to create.

type: number

Default value: 150

Example:

new Confetti(document.querySelector('#confetti'), {
	particleCount: 200,
});

particleSize

Size of the confetti particles in pixels

type: number

Default value: 12

Example:

new Confetti(document.querySelector('#confetti'), {
	particleSize: 20,
});

particleShape

Shape of particles to use. Can be mix, circles or rectangles

mix will use both circles and rectangles circles will use only circles rectangles will use only rectangles

type: 'mix' | 'circles' | 'rectangles'

Default value: 'mix'

Example:

new Confetti(document.querySelector('#confetti'), {
	particleShape: 'circles',
});

duration

Duration of the animation in milliseconds

type: number

Default value: 3500

Example:

new Confetti(document.querySelector('#confetti'), {
	duration: 5000,
});

colors

Colors to use for the confetti particles. Pass string array of colors. Can use hex colors, named colors, CSS Variables, literally anything valid in CSS.

type: Array<string>

Default value: ['#FFC700', '#FF0000', '#2E3191', '#41BBC7']

Example:

new Confetti(document.querySelector('#confetti'), {
	colors: ['var(--yellow)', 'var(--red)', '#2E3191', '#41BBC7'],
});

force

Force of the confetti particles. Between 0 and 1. 0 is no force, 1 is maximum force. Will error out if you pass a value outside of this range.

type: number

Default value: 0.5

Example:

new Confetti(document.querySelector('#confetti'), {
	force: 0.3,
});

stageHeight

Height of the stage in pixels. Confetti will only fall within this height.

type: number

Default value: 800

Example:

new Confetti(document.querySelector('#confetti'), {
	stageHeight: 500,
});

stageWidth

Width of the stage in pixels. Confetti will only fall within this width.

type: number

Default value: 1600

Example:

new Confetti(document.querySelector('#confetti'), {
	stageWidth: 500,
});

destroyAfterDone

Whether or not destroy all confetti nodes after the duration period has passed. By default it destroys all nodes, to free up memory.

type: boolean

Default value: true

Example:

new Confetti(document.querySelector('#confetti'), {
	destroyAfterDone: false,
});

Fine-grained reactivity

Changing the options will destroy the existing confetti mid-flight, and create a new one with the new options. Exception: If particlesCount isn't changed, and properties like colors or particleShape is changed, the confetti particles will change their colors or shape mid-flight.

Performance

This library functions by creating 2 DOM nodes for every single confetti. By default, if the particlesCount is set to 150, it will create 300 nodes. This is a lot of nodes. For most devices, these many nodes are not a big issue, but I recommend checking your target devices' performance if you choose to go with a higher number, like 400 or 500.

Also, after the specified duration, all the confetti DOM nodes will be destroyed. This is to free up memory. If you wish to keep them around, set destroyAfterDone to false.

This library is the port of the amazing react-confetti-explosion package, just 10X smaller and faster. All the logic is from that package only, optimisation and Svelte code are mine 😉
