The BarcodeDetector() constructor creates a new BarcodeDetector object which detects linear and two-dimensional barcodes in images.

options Optional

An options object containing a series of BarcodeFormats to search for in the subsequent detect() calls. The options are:

formats

An Array of barcode formats as strings. To see a full list of supported formats see the Barcode Detection API.

This example creates a new barcode detector object, with specified supported formats and tests for browser compatibility.

// create new detector
const barcodeDetector = new BarcodeDetector({
  formats: ["code_39", "codabar", "ean_13"],
});

// check compatibility
if (barcodeDetector) {
  console.log("Barcode Detector supported!");
} else {
  console.log("Barcode Detector is not supported by this browser.");
}
