Package Exports

dynamsoft-javascript-barcode

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (dynamsoft-javascript-barcode) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

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.
