React Simple QR Scanner

GitHub release Size GitHub license

A simple React wrapper around browser native BarcodeDetector API.

Compatibility

⚠️ Support is really not good at the moment, but enough for my use case. If I have the time I may try to use the canvas method to have a fallback when BarcodeDetector is not available. You can check here the global support of this API: caniuse

Setup

npm i @fabiendeborde/react-simple-qr-scanner
yarn add  @fabiendeborde/react-simple-qr-scanner

Props

name type default description
onScan -required- (decoded: string) => void none Scan event handler (will be called with the decoded string)
containerStyle React.CSSProperties empty object A style object for the video wrapper element
videoStyle React.CSSProperties empty object A style object for the video element
withTorch boolean false Toggle the camera torch (light)
focusMode ‘manual’, ‘single-shot’, ‘continuous’ ‘continuous’ Set the camera focus mode
facingMode ‘environment’, ‘user’ none Specify which camera should be used (if available)

Usage

<QrScanner
  onScan={(decoded) => console.log(decoded)}
  facingMode="environment"
  withTorch={false}
  focusMode="continuous"
/>

You can also find a really basic example in the example folder of this repository.
