snowfall.js v1.0.2

snow.js

Snow.js is a stand alone javascript library that helps "cool down" the web with a beautiful snowfall.

Installation

npm i snowfall.js -- save

JS

The setup to run snow.js is fairly simple. You will have to create a new instance of Snow, and pass it an element id that you want to encapsulate the snowfall.

<div id="snow"></div>

<script type="module">
//import the Snow module
import * as Snow from '/node_modules/snowfall.js/snow.js'

// Snow script included on the page, already.
window.onload = function () {
    var snow = new Snow.default({
        id: 'snow'
    });

    //Can run the snowfall by calling:
    snow.start();
}
</script>

There are also optional elements that you can pass to customize the snowfall....

Themes

The default theme displays the ordinary white snowflakes. However if you want something more bright then you can use the theme colors.

<script type = "module">
window.onload = function () {
    var snow = new Snow.default({
        id: 'snow',
        theme: 'colors'
    });
}
</script>

If blue is your favorite color, you can use the theme blues!

There are also the themes: berry, pastel, and purple to help your snowfall be a little more unique.

Snowflake Size

If you want to change the range of the snowflake sizes, then you can pass a min and max size element:

<script type = "module">
window.onload = function () {
    var snow = new Snow.default({
        id: 'snow',
        theme: 'colors',
        min_size: 3,
        max_size: 300
    });
}
</script>

For reference the default range is a min size of 2 and a max size of 7.

Toggle Snowfall

Maybe you do not want snowfall on your website 24/7? In that case, you can stop the snowfall with snow.stop() and you can toggle the snowfall with snow.toggle().

The toggle feature can be good, for example, if you want the user to be able to switch back and forth between snow and no snow by a mouse click as seen with the code...

<script type="module">
window.onload = function () {
    //create new snow
    var snow = new Snow.default({
        id: 'snow',
        theme: 'berry',
        min_size: 1,
        max_size: 5
    });
    snow.start();

    document.querySelector("body").onclick = function () {
        snow.toggle();
    }
}
</script>
