SVGuitar - JavaScript Guitar Chord Renderer
JavaScript (TypeScript) library to create beautiful SVG guitar chord charts directly in the browser.
To see this library in action check out chordpic.com, a free online chord diagram creator.
Demo: https://omnibrain.github.io/svguitar/ [ source ]
TypeScript API Documentation: https://omnibrain.github.io/svguitar/docs/
Example chord charts:
Getting Started
<!--container of the chart-->
<div id="chart"></div>
<!--load umd script -->
<script src="https://omnibrain.github.io/svguitar/js/svguitar.umd.js"></script>
<script>
// initialize the chart
var chart = new svguitar.SVGuitarChord('#chart')
// draw the chart
chart
.configure({
/* configuration */
})
.chord({
/* chord */
})
.draw()
</script>
Of course you can also add SVGuitar as a dependency to your project:
# Add the dependency to your project
npm install --save svguitar
# or
yarn add svguitar
And then import it in your project:
import { SVGuitarChord } from 'svguitar'
const chart = new SVGuitarChord('#chart')
// draw the chart
chart
.configure({
/* configuration */
})
.chord({
/* chord */
})
.draw()
Usage
The SVG charts are highly customizable. For a full API documentation have a look at the TypeScript documentation.
Chart configuration is completely optional, you don't have to pass any configuration or you can only override specific settings.
Here's an example of a very customized chart:
new SVGuitarChord('#some-selector')
.chord({
// array of [string, fret, text | options]
fingers: [
// finger at string 1, fret 2, with text '2'
[1, 2, '2'],
// finger at string 2, fret 3, with text '3', colored red and has class '.red'
[2, 3, { text: '3', color: '#F00', className: 'red' }],
// finger is triangle shaped
[3, 3, { shape: 'triangle' }],
[6, 'x'],
],
// optional: barres for barre chords
barres: [
{
fromString: 5,
toString: 1,
fret: 1,
text: '1',
color: '#0F0',
textColor: '#F00',
className: 'my-barre-chord',
},
],
// title of the chart (optional)
title: 'F# minor',
// position (defaults to 1)
position: 2,
})
.configure({
// Customizations (all optional, defaults shown)
