Why?

Have you ever seen that cool looking confetti on landing pages and above-the-fold content? We give you the power to create the same effect for free and without the hassle of having to design or code it from scratch.

Installing/Using

📲 Downloading

• Using npm

    npm install confetti-js --save

• Direct download -> click here

➕ Add scripts

• The classic way

  <script src="node_modules/confetti-js/dist/index.min.js"></script>

• ES6 module

  // At the component you want to use confetti
  import ConfettiGenerator from "confetti-js";

🤔 How to use it?

After installing the plugin(the topic above), just call-it passing your options:

html

<canvas id="my-canvas"></canvas>

javascript

var confettiSettings = { target: 'my-canvas' };
var confetti = new ConfettiGenerator(confettiSettings);
confetti.render();

You can also pass a canvas element as the target:

var confettiElement = document.getElementById('my-canvas');
var confettiSettings = { target: confettiElement };
var confetti = new ConfettiGenerator(confettiSettings);
confetti.render();

React

React.useEffect(() => {
  const confettiSettings = { target: 'my-canvas' };
  const confetti = new ConfettiGenerator(confettiSettings);
  confetti.render();

  return () => confetti.clear();
}, []) // add the var dependencies or not

done!

Options

Attribute	Description	Example value	Default value
target	The Id tag or node of the canvas that will be used	'my-canvas'	'confetti-holder'
max	The number of props(confetti) to be rendered	11	80
size	Prop size	1.8	1
animate	If the confetti should fall	false	true
respawn	If the confetti should be recreated after going off-screen	false	true
clock	The speed confetti fall	50	25
props	The type of props(confetti) that should be rendered. In addition to those listed in the default, there's a special "svg" type which requires further configuration and is detailed below.	['circle', 'square']	['circle', 'square', 'triangle', 'line']
colors	The color to be rendered on the confetti. By default, RGB format inside an array.	[[0,0,0], [255,255,255]]	[[165,104,246],[230,61,135],[0,199,228],[253,214,126]]
start_from_edge	Whether the confettis should fall from the top of the screen (or should move up from the bottom)	true	false
width	Canvas width	960	window size
height	Canvas height	767	window height
rotate	If set to true, SVG and squares will rotate while falling.	true	false

Special SVG particle type

There is an extra special partical type ("prop") which allows you to render SVGs as confetti particles. For example:

{
  "props": [
    "circle",
    "square",
    { "type": "svg", "src": "site/hat.svg" }
  ]
}

You must specify the type and src properties. There are also a few other configuration properties available to SVG objects:

Attribute	Description	Example value	Default value
size	Set the size of the SVG when it renders as a particle.	25	15
weight	The probability of this particle being rendered, where 1 is a regular weight, and 0.1 is uncommon.	0.5	1

API

Using the object generated by new ConfettiGenerator() is pretty easy, there're just two main methods actually.

Method	Description
render	Render the confetti at the config <canvas/>
clear	Clear the <canvas/> where the confetti where rendered

var confetti = new ConfettiGenerator();
confetti.render();
//
confetti.clear();

License

You can use/hack/re-distribute/do whatever you want with this for free without having to credit the author or anything. Go on, just do it.

But if you take the time to contribute with the project it would be nice too, just saying :)

Thanks

Special thanks to "Paper Matthew" on codepen for providing the starting point wich I fork to build this. You are awesome.
