How to generate a EAN-8 barcode as a PNG file in Node.JS

Setting up a barcode system in Node.JS all by yourself can be a bit intimidating. To help ease that load a bit, we have developed an API that will help you in generating EAN-8 barcodes. Using it is a piece of cake, as you are about to see.

First comes our client installation, which just means adding a reference to your package.json file.

"dependencies": {
    "cloudmersive-barcodeapi-client": "^1.1.2"
  }

The next step is to call our function, in this case generateBarcodeEAN8.

var CloudmersiveBarcodeapiClient = require('cloudmersive-barcodeapi-client');

var defaultClient = CloudmersiveBarcodeapiClient.ApiClient.instance;

// Configure API key authorization: Apikey

var Apikey = defaultClient.authentications['Apikey'];

Apikey.apiKey = 'YOUR API KEY';

// Uncomment the following line to set a prefix for the API key, e.g. "Token" (defaults to null)

//Apikey.apiKeyPrefix = 'Token';

var apiInstance = new CloudmersiveBarcodeapiClient.GenerateBarcodeApi();

var value = "value_example"; // String | Barcode value to generate from

var callback = function(error, data, response) {

if (error) {

console.error(error);

} else {

console.log('API called successfully. Returned data: ' + data);

}

};

apiInstance.generateBarcodeEAN8(value, callback);

Done! Yup, it’s just that simple. Any string that you enter in for the value will be encoded as a EAN-8. We have API support for a variety of other barcode formats as well, including QR, EAN-13, and more.
