A fast and efficient (QR) barcode scanner plugin for Capacitor apps, supporting iOS, Android, and Web.
Barcode Scanner is a Capacitor plugin that enables barcode and QR code scanning in cross-platform mobile and web applications. It provides a unified JavaScript API that works on iOS, Android, and the web, using native platform libraries for optimal performance. The plugin solves the need for a reliable, fast scanning solution without requiring separate implementations for each platform.
Developers building Capacitor-based applications who need to integrate barcode or QR code scanning functionality. This includes teams creating retail apps, inventory management systems, event check-in apps, or any application requiring data capture from physical barcodes.
Developers choose this plugin because it offers a consistent API across all Capacitor platforms with excellent performance through native libraries. It provides fine-grained control over barcode formats, comprehensive permission handling, and is maintained by the Capacitor community with clear version compatibility.

Provides a consistent JavaScript interface for iOS, Android, and web, simplifying development with a single codebase for barcode scanning.
Leverages Apple's AVFoundation on iOS and zxing libraries on Android/Web for fast, reliable scanning, as highlighted in the platform-specific implementation notes.
Supports numerous 1D and 2D formats like QR_CODE, CODE_128, and PDF_417, with detailed tables showing platform compatibility for targeted scanning.
Includes checkPermission() with force options and openAppSettings() for handling camera permissions, complete with UX-optimized code examples in the README.
Offers a prepare() method to pre-initialize the scanner, reducing startup latency for a smoother user experience.
The project is officially deprecated in favor of @capacitor/barcode-scanner, meaning no future updates, bug fixes, or community support.
The web implementation is noted as 'in development' with potential issues and not all features supported, limiting its reliability for web-based apps.
Some barcode formats like UPC_EAN_EXTENSION or CODABAR are not supported on all platforms, requiring manual handling and reducing cross-platform consistency.
Requires additional CSS variables and JavaScript workarounds for Ionic frameworks, as detailed in the troubleshooting section, adding setup complexity.
