Generate Postnet Labels with Node.js via Java

Create Postnet barcode in JavaScript using server-side Aspose.BarCode for Node.js via Java API.

How to Generate Postnet barcode Using Node.js via Java

To create Postnet barcode barcodes within Node.js applications, acquire the Aspose.BarCode for Node.js via Java, an advanced, potent, and user-friendly barcode API designed for Java-oriented platforms. You can easily install aspose.barcode for Javascript from NPM:

Command  > npm i aspose.barcode

Steps to Generate Postnet barcode in JavaScript

Aspose.BarCode makes it easy for developers to create Postnet barcode images with few lines of code.

Create an instance of BarCodeGenerator class
Set Postnet barcode as the EncodeTypes parameter
Define text to encode as the second parameter
Determine barcode dimensions and location if needed
Call the BarCodeGenerator.save method to get the generated barcode image

System Requirements

Aspose barcode APIs are supported by all major platforms and operating systems. Before executing the code sample below, please check that you have the following prerequisites enabled in your system.

Microsoft Windows, Linux, or any OS compatible with Node.js

Oracle JDK version 7 or above

Show codetext

Code to be executed - JavaScript


const barcode_ = require("aspose.barcode");
const aspose_barcode = barcode_.AsposeBarcode

let BarcodeGenerator = aspose_barcode.BarcodeGenerator;
let EncodeTypes = aspose_barcode.EncodeTypes;

// Create an instane of the BarcodeGenerator class
let generator = new BarcodeGenerator(EncodeTypes.QR, "");

// Specify the X-dimension 
// the smallest width of the unit of BarCode bars or spaces
generator.getParameters().getBarcode().getXDimension().setMillimeteres(2);

// Set codetext position
generator.getParameters().getBarcode().getCodeTextParameters().setLocation(CodeLocation.Below);

// Generate and save image
generator.save("example.png", aspose_barcode.BarCodeImageFormat.PNG);
