Geração e reconhecimento de códigos de barras para Node.js via Java

// 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);

const barcode = require("aspose.barcode");
const { BarCodeReader, DecodeType, QualitySettings } = barcode.AsposeBarcode;

// Create instance of BarCodeReader
const reader = new BarCodeReader("photo.png", null, [DecodeType.QR, DecodeType.CODE_128]);

// Set recognition quality settings
reader.setQualitySettings(QualitySettings.getHighPerformance());

// Read barcodes on image
reader.readBarCodes().forEach(r => {
  console.log(r.getCodeTypeName(), r.getCodeText());
});
