react-confetti-explosion

React Confetti Explosion

This is inspired by this beautiful and oft-used confetti which uses canvas, but equally inspired by how many bad looking CSS examples there are out there. The goal was to create a super lightweight confetti component that would not require canvas, use only CSS for animation, and could also be controlled as an explosion (rather than raining confetti), without the need to write a full-blown particle generator.

Install:

$ yarn add react-confetti-explosion

Usage

import ConfettiExplosion from 'react-confetti-explosion';

function App() {
  const [isExploding, setIsExploding] = React.useState(false);
  return <>{isExploding && <ConfettiExplosion />}</>;
}

Optional Props

Name	Type	Default	Description
particleCount	number	150	Total number of particles used. Generally try to stay under 400 for optimal performance.
particleSize	number	12	Size of particles in pixels. This means width for squares, diameter for circles. Note there is also a bit of randomness added to these.
duration	number	3500	Duration of explosion in ms. This is the time it takes particles to travel from explosion point to the floor, as defined by height.
colors	string[]	[ '#FFC700', '#FF0000', '#2E3191', '#41BBC7' ]	An array of any css-readable colors, which are evenly distributed across the number of total particles.
force	number	0.5	Between 0-1, roughly the vertical force at which particles initially explode. Straying too far away from 0.5 may start looking...interesting.
height	number	800	Pixel distance the particles will vertically spread from initial explosion point.
width	number	1600	Pixel distance the particles will horizontally spread from initial explosion point.

Although the duration of the explosion is controlled, it is up to the consumer how and when the ConfettiExplosion is rendered and positioned (and, hey, maybe even faded out?).

Potential gotchas

• Your container must be overflow: visible in order to allow elements to fully spread across area.
• If your height is too small, particles may visibly land on the floor instead of disappearing off-screen.

To keep the library as little as possible much of the physics have been estimated, cheapened, and downright mutilated. There are certainly prop combinations that will not look realistic, due to the limitations of CSS animations. But there should be enough options to fit most needs.
