JavaScript Barcode Scanner SDK

The JavaScript Barcode Scanner SDK is a JavaScript barcode scanning library. It can be integrated into your website or web app to provide barcode scanning directly in the browser.

The JavaScript API allows you to access cameras available on the device for video input, display a barcode scanner interface, configure in-depth settings for AI-powered scanning and performance, and customize the UI for your users and brand.

All samples for the JavaScript Barcode Scanner SDK are in the GitHub repo datacapture-web-samples. Instructions for running the samples are in our Web SDK Samples guide.

You will need a license key to run the samples. You can obtain one by signing up for a free trial of the SDK.

Yes! Our JavaScript Barcode Scanner SDK demo app is available to run in your browser here.

This demo app includes instructions on how to use different barcode scanning features – all available within the SDK.

Our Javascript barcode scanner supports 30+ of the most common barcodes, including UPC, EAN, Code 39, Code 128, ITF, Code 93, Codabar, Databar, MS1 Plessey, QR codes, DataMatrix, PDF417 and Aztec codes. 

For a detailed list please refer to our Supported Symbologies documentation page.

With the Scandit JavaScript SDK you can scan barcodes from almost any modern browser. For Android, these include Chrome, Firefox and Edge; for iOS: Safari. See the full list of Web platforms and browser compatibility. 

JavaScript apps commonly use callbacks, called event listeners, that trigger actions in response to successful barcode scans.

Scandit’s JavaScript barcode scanning library provides a BarcodeCaptureListener interface that you can implement to inform your app whenever a new barcode is recognized, and the BarcodeCaptureSession class that contains the list of barcodes to handle.

Yes! The Scandit JavaScript SDK ships with full TypeScript support.

The Scandit JavaScript main library size is 28.6 kB. This article gives you a more detailed overview of the size of the Scandit Javascript library. 

This size is for the files minified and gzipped. Keep in mind that you will not need to wait for these files to download to display your webpage/web application, they can be downloaded and prepared in the background without affecting the rest of the application.

Our production licenses do not require a continuous internet connection. However, test licenses require an internet connection during scanning. 

If you need to test offline, we can provide a license key – please contact support.

To implement Scandit barcode scanning in JavaScript, roughly, you will need to install the SDK, configure and initialize the library, enable barcode symbologies, register a barcode capture listener to receive scan events, and consider how to design your scanning UI. Learn more in our documentation, or read our developer’s guide on how to add javascript barcode scanner to Web apps.
