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

```bash

npm install confetti-js --save

```

• Direct download -> click here

➕ Add scripts

• The classic way

```html ```

• ES6 module

```javascript // 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();

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.
