    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.

    Supported barcodes:

    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


    Example with options:

    JsBarcode("#barcode", "1234", {
      format: "pharmacode",
      lineColor: "#0aa",
      displayValue: false


    More advanced use case:

      .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})


    Or define the value and options in the HTML element:

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

    <svg class="barcode"

    And then initialize it with:



    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 :smile:

    Bower and npm:

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

    bower install jsbarcode --save
    npm install jsbarcode --save


    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 for more information

    With svg:

    const { DOMImplementation, XMLSerializer } = require('xmldom');
    const xmlSerializer = new XMLSerializer();
    const document = new DOMImplementation().createDocument('', 'html', null);
    const svgNode = document.createElementNS('', 'svg');
    JsBarcode(svgNode, 'test', {
        xmlDocument: document,
    const svgText = xmlSerializer.serializeToString(svgNode);
