Introduction

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

Demo

Supported barcodes:

Examples for browsers:

First create an canvas (or image)

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

Simple example:

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

Result

Example with options:

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

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:

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:

Result

Setup for browsers:

Step 1:

Step 2:

Include the script in your code:

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

Bower:

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

bower install jsbarcode --save

Node.js:

Install with npm:

npm install jsbarcode
npm install canvas

Use:

var JsBarcode = require('jsbarcode');
var Canvas = require("canvas");

var canvas = new Canvas();
JsBarcode(canvas, "Hello");

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