Use the sample source code below to generate barcodes in JavaScirpt using Cloud API (low level).

You can also read barcodes in JavaScript using Cloud API.

POST/GET endpoint:

https://bytescout.io/v1/barcode/generate

Code Sample:

var Bytescoutio = require('bytescoutio');
var defaultClient = Bytescoutio.ApiClient.instance;

// Configure API key authorization: api_key
var api_key = defaultClient.authentications['api_key'];
api_key.apiKey = "YOUR API KEY"
// Uncomment the following line to set a prefix for the API key, e.g. "Token" (defaults to null)
//api_key.apiKeyPrefix['x-api-key'] = "Token"

var api = new Bytescoutio.DefaultApi()

var opts = { 
  'name': name_example, // {String} Filename for the generated image.
  'type': type_example, // {String} Barcode type. Valid values: Code128, Code39, Postnet, UPCA, EAN8, ISBN, Codabar, I2of5, Code93, EAN13, JAN13, Bookland, UPCE, PDF417, PDF417Truncated, DataMatrix, QRCode, Aztec, Planet, EAN128, GS1_128, USPSSackLabel, USPSTrayLabel, DeutschePostIdentcode, DeutschePostLeitcode, Numly, PZN, OpticalProduct, SwissPostParcel, RoyalMail, DutchKix, SingaporePostalCode, EAN2, EAN5, EAN14, MacroPDF417, MicroPDF417, GS1_DataMatrix, Telepen, IntelligentMail, GS1_DataBar_Omnidirectional, GS1_DataBar_Truncated, GS1_DataBar_Stacked, GS1_DataBar_Stacked_Omnidirectional, GS1_DataBar_Limited, GS1_DataBar_Expanded, GS1_DataBar_Expanded_Stacked, MaxiCode, Plessey, MSI, ITF14, GTIN12, GTIN8, GTIN13, GTIN14.
  'value': value_example // {String} Barcode value.
};

var callback = function(error, data, response) {
  if (error) {
    console.error(error);
  } else {
    console.log('API called successfully. Returned data: ' + data);
  }
};
api.barcodeGeneratePost(opts, callback);
