How to integrate the Scanbot JavaScript QR Code Scanner using our Ready-To-Use UI
The Ready-To-Use UI (RTU UI) is an easy-to-integrate and highly customizable high-level UI component (HTML page) that can handle most barcode scanning use cases and tasks. The design and behavior of this component are based on our many years of experience as well as the feedback from our SDK customers.
Although the main idea of the RTU UI is to provide simple-to-integrate and simple-to-configure components, its customization capabilities are numerous and should suit most of your needs. To achieve an even higher degree of customization, you can implement a custom UI and business logic using our Classic SDK UI Components.
Dependencies
Ready-To-Use UI Components are within a separate binary, but the same npm package. Instead of loading our basic SDK, you need to load the ui2
binary of ScanbotSDK:
import ScanbotSDK from 'scanbot-web-sdk/ui';
And now you’re ready to work with RTU UI Components. It’s as easy as that!
Launching the RTU UI Barcode Scanner
With just a few lines of code, you can integrate barcode scanning into your application’s workflow:
import ScanbotSDK from "scanbot-web-sdk/ui";
import { BarcodeScannerConfiguration } from "scanbot-web-sdk/@types/ui2/configuration";
export default function startScanner(config: BarcodeScannerConfiguration) {
// TODO: Configure as needed
const result = ScanbotSDK.UI.createBarcodeScanner(config);
// TODO: Process & present the result as needed
return result;
}
Frequently Asked Questions
What is a JavaScript QR code scanner?
