// npm i aspose.barcode
const barcode = require("aspose.barcode");
const { BarcodeGenerator, EncodeTypes, BarCodeImageFormat } = barcode.AsposeBarcode;

// Create instance of BarcodeGenerator
const gen = new BarcodeGenerator(EncodeTypes.CODE_128, "SKU-12345");

// Set barcode x-dimension in pixels
gen.getParameters().getBarcode().getXDimension().setPixels(4);

// Generate barcode and Save to PNG
gen.save("barcode.png", BarCodeImageFormat.PNG);

Java-grade barcode accuracy for Node backends

Node.js services often deal with real-world input: mobile photos, warehouse labels, scanned documents, and PDFs. This SDK exposes a mature Java barcode engine to Node.js so you can keep your stack and still decode reliably under imperfect conditions.

Standards? Covered.

Aspose.BarCode for Node.js via Java supports all major image formats, including vector formats like SVG and EMF, as well as PDF. Use our API to recognize files from scanners or cameras with ease. Here are all supported barcode symbologies, including 1D, 2D, postal, and composite types. Each one can be generated and recognized across all supported platforms.

Matrix / 2D Codes

QR Code, MicroQR, rMQR
Data Matrix, Industrial Data Matrix (DPM)
Aztec
Han Xin
MaxiCode
DotCode

Linear / 1D Codes

UPCA, UPCE
EAN13, EAN14, EAN8
Code 128

Deploy to any Node.js environment

Run on Windows, Linux, macOS, or Solaris wherever Node.js and Java are available. Install from npm and call the API from microservices, background workers, and batch pipelines through a Node.js to Java bridge.

Node.js 18 or higher
Java JDK 8 or higher (OpenJDK, Amazon Corretto, BellSoft Liberica, Oracle JDK)
Install via npm: `npm install aspose.barcode`
Java engine with a JavaScript-friendly API via the Node.js-to-Java bridge

Live Code Demo

Paste text → get a barcode. Drop a file → get decoded data. Both examples come with auto-generated sample code so you can copy straight into your project.

Type

Text

X-dimension

Border color

Image format

// Initialize BarcodeGenerator
let gen = new BarcodeGenerator(EncodeTypes.QR, "1234567");
// Set generation parameters
gen.getParameters().getBarcode().getXDimension().setPixels(7);
gen.getParameters().getBorder().setColor("#ff000000");
gen.getParameters().getBorder().getWidth().setPixels(7);
// Generate and save Barcode image
gen.save("image.png", BarCodeImageFormat.PNG);

Type

Recognition quality

// Initialize BarCodeReader
let reader = new BarCodeReader("image.png", null, DecodeType.QR);
// Set recognition quality
reader.setQualitySettings(QualitySettings.getHighPerformance());
// Recognize barcodes and output results
let res = reader.readBarCodes();
console.log(`Recognized ${res.length} barcode(s)`);
for (const result of res)
{
console.log(`${result.getCodeTypeName()}: ${result.getCodeText()}`);
}

Barcode workflows for APIs, jobs, and documents

Build reliable barcode flows in Node.js without moving processing to external services. Generate print-ready labels, validate incoming codes, and decode from images or PDFs in backend pipelines.

Generate 1D and 2D barcodes for labels, tickets, invoices, and product packaging
Read barcodes from raster images and PDF documents
Tune recognition for speed or tolerance using presets and detailed settings
Output to common raster formats and vector formats (SVG, EMF) when needed
Return rich results: code text, symbology, region, and orientation

High-throughput recognition for services and batches

Scale from single requests to bulk processing. Detect multiple barcodes per image, focus on regions to speed up large frames, and switch recognition presets per workload.
