Introduction

JsBarcode is a barcode generator written in JavaScript. It supports multiple barcode formats and works in browsers and with Node.js. It has no dependencies when it is used for the web but works with jQuery if you are into that.

Examples for browsers:

First create a canvas (or image)

<svg id="barcode"></svg>
<!-- or -->
<canvas id="barcode"></canvas>
<!-- or -->
<img id="barcode"/>

Simple example:

JsBarcode("#barcode", "Hi!");
// or with jQuery
$("#barcode").JsBarcode("Hi!");

Result:

Example with options:

JsBarcode("#barcode", "1234", {
  format: "pharmacode",
  lineColor: "#0aa",
  width:4,
  height:40,
  displayValue: false
});

Result:

More advanced use case:

JsBarcode("#barcode")
  .options({font: "OCR-B"}) // Will affect all barcodes
  .EAN13("1234567890128", {fontSize: 18, textMargin: 0})
  .blank(20) // Create space between the barcodes
  .EAN5("12345", {height: 85, textPosition: "top", fontSize: 16, marginTop: 15})
  .render();

Result:

Or define the value and options in the HTML element:

Use any jsbarcode-* or data-* as attributes where * is any option.

<svg class="barcode"
  jsbarcode-format="upc"
  jsbarcode-value="123456789012"
  jsbarcode-textmargin="0"
  jsbarcode-fontoptions="bold">
</svg>

And then initialize it with:

JsBarcode(".barcode").init();

Result:

Retrieve the barcode values so you can render it any way you'd like

Pass in an object which will be filled with data.

const data = {};
JsBarcode(data, 'text', {...options});

data will be filled with a encodings property which has all the needed values. See wiki for an example of what data looks like.

Setup for browsers:

Step 1:

Download or get the CDN link to the script:

Name	Supported barcodes	Size (gzip)	CDN / Download
All	All the barcodes!	10.1 kB	JsBarcode.all.min.js
CODE128	CODE128 (auto and force mode)	6.2 kB	JsBarcode.code128.min.js
CODE39	CODE39	5.1 kB	JsBarcode.code39.min.js
EAN / UPC	EAN-13, EAN-8, EAN-5, EAN-2, UPC (A)	6.6 kB	JsBarcode.ean-upc.min.js
ITF	ITF, ITF-14	5 kB	JsBarcode.itf.min.js
MSI	MSI, MSI10, MSI11, MSI1010, MSI1110	5 kB	JsBarcode.msi.min.js
Pharmacode	Pharmacode	4.7 kB	JsBarcode.pharmacode.min.js
Codabar	Codabar	4.9 kB	JsBarcode.codabar.min.js

Step 2:

Include the script in your code:

<script src="JsBarcode.all.min.js"></script>

Step 3:

You are done! Go generate some barcodes 😄

Bower and npm:

You can also use Bower or npm to install and manage the library.

bower install jsbarcode --save

npm install jsbarcode --save

Node.js:

With canvas:

var JsBarcode = require('jsbarcode');

// Canvas v1
var Canvas = require("canvas");
// Canvas v2
var { createCanvas } = require("canvas");

// Canvas v1
var canvas = new Canvas();
// Canvas v2
var canvas = createCanvas();

JsBarcode(canvas, "Hello");

// Do what you want with the canvas
// See https://github.com/Automattic/node-canvas for more information

With svg:

const { DOMImplementation, XMLSerializer } = require('xmldom');
const xmlSerializer = new XMLSerializer();
const document = new DOMImplementation().createDocument('http://www.w3.org/1999/xhtml', 'html', null);
const svgNode = document.createElementNS('http://www.w3.org/2000/svg', 'svg');

JsBarcode(svgNode, 'test', {
    xmlDocument: document,
});

const svgText = xmlSerializer.serializeToString(svgNode);
