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:

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!	9.6 kB	JsBarcode.all.min.js
CODE128	CODE128 (auto and force mode)	6 kB	JsBarcode.code128.min.js
CODE39	CODE39	5 kB	JsBarcode.code39.min.js
EAN / UPC	EAN-13, EAN-8, EAN-5, EAN-2, UPC (A)	6.2 kB	JsBarcode.ean-upc.min.js
ITF-14	ITF-14	4.8 kB	JsBarcode.itf-14.min.js
ITF	ITF	4.7 kB	JsBarcode.itf.min.js
MSI	MSI, MSI10, MSI11, MSI1010, MSI1110	4.9 kB	JsBarcode.msi.min.js
Pharmacode	Pharmacode	4.6 kB	JsBarcode.pharmacode.min.js
Codabar	Codabar	4.8 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 😄
