Usage

Node

var dbr = require('dynamsoft-javascript-barcode');
dbr.BarcodeReader.productKeys = 'LICENSE-KEY';
dbr.BarcodeReader.createInstance().then(reader => {
    reader.decode('sample.png').then(results => {
        for(var i = 0; i < results.length; ++i){
            console.log(results[i].BarcodeText);
        }
        reader.destroy();
    });
});

Web

<!DOCTYPE html>
<html>
<body>
    <script src="node_modules/dynamsoft-javascript-barcode/dist/dbr.min.js" data-productKeys="LICENSE-KEY"></script>
    <script>
        let barcodeScanner = null;
        Dynamsoft.BarcodeScanner.createInstance({
            onFrameRead: results => {console.log(results);},
            onUnduplicatedRead: (txt, result) => {alert(txt);}
        }).then(scanner => {
            barcodeScanner = scanner;
            barcodeScanner.show();
        });
    </script>
</body>
</html>

Alternatively, you can use the jsDelivr CDN as follows:

<!DOCTYPE html>
<html>
<body>
    <script src="https://cdn.jsdelivr.net/npm/dynamsoft-javascript-barcode@7/dist/dbr.min.js" data-productKeys="LICENSE-KEY"></script>
    <script>
        let barcodeScanner = null;
        Dynamsoft.BarcodeScanner.createInstance({
            onFrameRead: results => {console.log(results);},
            onUnduplicatedRead: (txt, result) => {alert(txt);}
        }).then(scanner => {
            barcodeScanner = scanner;
            barcodeScanner.show();
        });
    </script>
</body>
</html>

Use Web Server for Chrome for quick deployment.
