An implementation of a real-time QR-code scanner using WebRTC
Using NPM:
npm install react-webcam-qr-scanner
Using Yarn:
yarn add react-webcam-qr-scanner
Here is an example of a simple React component that utilizes react-webcam-qr-scanner
import React from "react";
import Scanner from "react-webcam-qr-scanner";
const MyAwesomeComponent = (props) => {
const handleDecode = (result) => {
console.log(result);
}
const handleScannerLoad = (mode) => {
console.log(mode);
}
return (
<Scanner
className="some-classname"
onDecode={handleDecode}
onScannerLoad={handleScannerLoad}
constraints={{
audio: false,
video: {
facingMode: "environment"
}
}}
captureSize={{ width: 1280, height: 720 }}
/>
);
}
Most of the props are identical to the React <video> tag (e.g. classname, name, id, event handlers etc). However, some of them define the decoder behaviour and can be set as follows:
Property | Type | Meaning |
---|---|---|
onDecode | function | a callback which fires when a QR-code is successfully decoded |
onScannerLoad | function | a callback which fires when QR-decoding script is successfully loaded |
constraints | object | a MediaStreamConstraints object |
captureSize | object { width: number, height: number } | Represents the size of the frame area sensitive for QR-detection |
