Getting Started with Scanbot JavaScript Barcode Scanner

Scanbot Web Barcode Scanner SDK is available as an npm package and also loadable via jsdelivr.

After the installation, first, you need to add a container element to your HTML file:

<div id="barcode-scanner-container"></div>

Then, you can easily start the JavaScript Barcode Scanner in your JavaScript app:

var barcodeScanner = await scanbotSDK.createBarcodeScanner({
				containerId: 'barcode-scanner-container',
				onBarcodesDetected: onBarcodesDetected,
			});
		

You can configure the 1D and 2D barcode types that you want to recognize:

var barcodeScanner = await scanbotSDK.createBarcodeScanner({
	    containerId: 'barcode-scanner-container',
	    …
	    barcodeFormats: [
	      "AZTEC",
	      "CODABAR",
	      "CODE_39",
	      "CODE_93",
	      "CODE_128",
	      "DATA_MATRIX",
	      "EAN_8",
	      "EAN_13",
	      "ITF",
	      "MAXICODE",
	      "PDF_417",
	      "QR_CODE",
	      "RSS_14",
	      "RSS_EXPANDED",
	      "UPC_A",
	      "UPC_E",
	      "UPC_EAN_EXTENSION",
	      "MSI_PLESSEY",
	    ]
	  });
	

Also, you can customize the UI style of your JavaScript Barcode Scanner:

var barcodeScanner = await scanbotSDK.createBarcodeScanner({
	    containerId: 'barcode-scanner-container',
	    …
	    style: {
	      window: {
	        aspectRatio: 1,
	        paddingPropLeft: 0.5,
	        borderColor: "white",
	        left: "50%",
	        top: "50%",
	        transform: "translate(-50%, -50%)"
	      },
	      text: {
	        color: "white",
	        size: "0.9em",
	        weight: 300,
	      },
	      backgroundColor: "rgba(0, 0, 0, 0.7)",
	      hint: "Please align the barcode or QR code in the frame"
	    }
	  });
