How to Generate an EAN-13 Barcode in JavaScript

While the UPC-A barcode is the standard across North America, the EAN-13 barcode is the most commonly used in Europe. This version contains 13 digits, and similar to the UPC-A format, it can be used internationally. In this brief tutorial, we will demonstrate how to automatically generate an EAN-13 barcode image using an API in JavaScript.

Our first step is to install the jQuery library:

bower install jquery

Next, we can call the function with the following code:

var settings = {
     "url": "https://api.cloudmersive.com/barcode/generate/ean-13",
     "method": "POST",
     "timeout": 0,
     "headers": {
          "Content-Type": "application/x-www-form-urlencoded",
          "Apikey": "YOUR-API-KEY-HERE"
     },
     "data": {
          "0": "<",
          "1": "s",
          "2": "t",
          "3": "r",
          "4": "i",
          "5": "n",
          "6": "g",
          "7": ">"
     }
};
$.ajax(settings).done(function (response) {
     console.log(response);
});

This will return a PNG file of the barcode that is downloadable and ready for use!
