SVGuitar - JavaScript Guitar Chord Renderer

Pipeline styled with prettier Coveralls semantic-release Known Vulnerabilities Code Style

JavaScript (TypeScript) library to create beautiful SVG guitar chord charts directly in the browser.

Demo: https://voellmy.gitlab.io/svguitar/ [ source ]

TypeScript API Documentation: https://voellmy.gitlab.io/svguitar/docs/

Example chord charts:

Example Chord Chart 1 Example Chord Chart 2 Example Chord Chart 3 Example Chord Chart 4

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)
