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.

* [Pharmacode](https://github.com/lindell/JsBarcode/wiki/pharmacode)
* [Codabar](https://github.com/lindell/JsBarcode/wiki/codabar)

Examples for browsers:
----

#### First create a canvas (or image)
````html
<svg id="barcode"></svg>
<!-- or -->
<canvas id="barcode"></canvas>
<!-- or -->
<img id="barcode"/>
````



#### Simple example:
````javascript
JsBarcode("#barcode", "Hi!");
// or with jQuery
$("#barcode").JsBarcode("Hi!");
````

##### Result:
![Result](https://s3-eu-west-1.amazonaws.com/js-barcode/barcodes/simple.svg)


#### Example with options:
````javascript
JsBarcode("#barcode", "1234", {
  format: "pharmacode",
  lineColor: "#0aa",
  width:4,
  height:40,
  displayValue: false
});
````
##### Result:
![Result](https://s3-eu-west-1.amazonaws.com/js-barcode/barcodes/advanced.svg)


#### More advanced use case:
````javascript
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](https://s3-eu-west-1.amazonaws.com/js-barcode/barcodes/simple.svg)



#### Or define the value and options in the HTML element:
Use any `jsbarcode-*` or `data-*` as attributes where `*` is any option.
````html
<svg class="barcode"
  jsbarcode-format="upc"
  jsbarcode-value="123456789012"
  jsbarcode-textmargin="0"
  jsbarcode-fontoptions="bold">
</svg>
````

And then initialize it with:
````javascript
JsBarcode(".barcode").init();
````

##### Result:
![Result](https://s3-eu-west-1.amazonaws.com/js-barcode/barcodes/init.svg)



#### Retrieve the barcode values so you can render it any way you'd like
Pass in an object which will be filled with data.
```javascript
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 kB*  |  *[JsBarcode.all.min.js][1]*  |
|  CODE128  |  CODE128 (auto and force mode)  |  6.1 kB  |  [JsBarcode.code128.min.js][2]  |
|  CODE39  |  CODE39  |  5 kB  |  [JsBarcode.code39.min.js][3]  |
|  EAN / UPC  |  EAN-13, EAN-8, EAN-5, EAN-2, UPC (A)  |  6.5 kB  |  [JsBarcode.ean-upc.min.js][4]  |
|  ITF  |  ITF, ITF-14  |  4.9 kB  |  [JsBarcode.itf.min.js][5]  |
|  MSI  |  MSI, MSI10, MSI11, MSI1010, MSI1110  |  4.9 kB  |  [JsBarcode.msi.min.js][6]  |
|  Pharmacode  |  Pharmacode  |  4.6 kB  |  [JsBarcode.pharmacode.min.js][7]  |
|  Codabar  |  Codabar  |  4.8 kB  |  [JsBarcode.codabar.min.js][8]  |


### Step 2:
Include the script in your code:


````html
<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](http://bower.io) or [npm](https://www.npmjs.com) to install and manage the library.
````bash
bower install jsbarcode --save
````
````bash
npm install jsbarcode --save
````

Node.js:
----

#### With canvas:
```` javascript
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:
```` javascript
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);
````
