JavaScript Barcode Scanner SDK

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.

Scandit’s JavaScript barcode scanning library can be integrated into your website 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 barcode symbologies and performance, and let users easily scan barcodes in your web application.

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.

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.

Our JavaScript barcode scanner supports 25+ 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.

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.
