A fast, energy-efficient, highly-configurable QR code scanner plugin for Cordova apps and the browser.
cordova-plugin-qrscanner is a plugin for Cordova applications that enables fast and efficient QR code scanning using the device's native camera. It solves the problem of building customizable scanning interfaces within hybrid mobile apps by rendering the camera preview behind the webview, allowing full HTML/CSS/JS control over the UI. It also works as a standalone library for browser-based projects.
Cordova/PhoneGap developers building hybrid mobile apps that require QR code scanning functionality, as well as web developers needing a QR scanner for browser, Electron, or NW.js applications.
Developers choose this plugin for its native performance, energy efficiency, and high configurability across multiple platforms. Its unique approach of placing the camera preview behind the webview enables fully customizable scanning interfaces without sacrificing speed.

Renders the camera feed natively behind the webview, enabling high-speed scanning without HTML5 video lag, as highlighted in the native camera preview feature.
Supports iOS, Android, Windows, and browser platforms including Electron and NW.js, providing a consistent API across diverse environments.
Optimizes battery usage by intelligently managing camera and processing resources, crucial for mobile apps with prolonged scanning needs.
Offers early permission priming via the prepare method and guides users to settings if denied, improving user onboarding and access handling.
Limited to QR code decoding only, not supporting other common barcode formats, which restricts its use in broader scanning applications.
On browser platforms, lacks light support, has simplified camera selection, and appends video preview to DOM, potentially causing styling conflicts and reduced functionality.
Requires Cordova setup and plugin installation, adding complexity for projects not already using Cordova or similar hybrid frameworks.
