Angular-html5qrcode

The Angular HTML5 QR Code Library provides a reusable Angular component and service that wraps the popular html5-qrcode library. It simplifies the integration of robust QR code and barcode scanning capabilities directly into Angular applications, eliminating the need for developers to handle low-level camera and file scanning APIs.

Key Features

• Angular Component — A ready-to-use <angular-html-qrcode> component with configurable input properties for scanning behavior.
• Flexible Scanning — Supports scanning via camera, file upload, or both, with configurable formats (QR_CODE and other barcodes).
• Customizable UI — Allows adjustment of scanning box dimensions, aspect ratio, frames per second, and camera selection persistence.
• Event Handling — Emits onSuccess and onError events for seamless integration with application logic.
• Service API — Provides an injectable service with methods to programmatically control scanning, including pause(), resume(), and clear().

Philosophy

The library is designed to offer a declarative, Angular-native interface for QR/barcode scanning, prioritizing developer experience and ease of integration while leveraging the underlying power of the html5-qrcode library.
