favicon-marquee

favicon-marquee

A <5 kB JavaScript class with no dependencies that adds an animated scrolling favicon to your website. See the demo.

This package is transpiled and polyfilled to be pre-ES6 compatible which means it works on all modern browsers

Install

You can either download the whole project or install it via npm or yarn:

$ npm install favicon-marquee
$ yarn add canvas-marquee

Usage

favicon-marquee can be bundled with all major build tools

import FaviconMarquee from "favicon-marquee";

or loaded using a script tag and used as a global variable

<script type="text/javascript" src="path/to/lib/main.js">

Now that FaviconMarquee is accessible, you can use it by running the following code

const marquee = new FaviconMarquee({
    text: 'easy!",
    font: '"Comic Sans MS", sans-serif',
});
marquee.start();

This will start the marquee in your current tab with the text easy!

FaviconMarquee can be customized by passing the following the properties to its constructor, although sensible defaults are provided:

text - text to be displayed in the favicon. This can be any unicode character including emojis, cyrillic, hangul, etc.
font - font of the text. This can be any valid CSS font-family value
color - color of the text to be displayed. Can be any valid CSS color value
background - color of the marquee's background. Transparent by default. Can be any valid CSS color value
step - specifies how many pixels the marquee scrolls each render. This can be used to speed up or slow down the text
size - size of the canvas used to render the marquee's text. A larger size results in a more detailed picture but might cause performance issues
marginBottom - the text rendered is displayed at the bottom of the favicon. This can optionally be used to add some margin to the bottom to center the text instead

These properties must be wrapped in an object before passing them to the constructor.

Additionally, a number can be passed into the start to control how often (in ms) the marquee is re-rendered.

const marquee = new FaviconMarquee({
    text: 'Different text',
    color: '#323330',
    size: 48,
    step: 0.5,
    background: "#F0DB4F",
    marginBottom: 3,
});
marquee.start(1000/30); // renders at 30 fps
