vue-qrcode-reader
Advanced tools
A set of Vue.js components for detecting QR codes and various other barcode formats right in the browser:
QrcodeStream
continuously scans frames from a camera stream.QrcodeDropZone
is an empty region where you can drag-and-drop images to be decoded.QrcodeCapture
is a classic file upload field, instantly scanning all files you select.All components are responsive. Beyond that, close to zero styling. Make them fit your layout. Usage is simple and straight forward:
<qrcode-stream @detect="onDetect"></qrcode-stream>
methods: {
onDetect (detectedCodes) {
// ...
}
}
Run
npm install vue-qrcode-reader
You can import the components independantly
import { QrcodeStream, QrcodeDropZone, QrcodeCapture } from 'vue-qrcode-reader'
const MyComponent = {
components: {
QrcodeStream,
QrcodeDropZone,
QrcodeCapture
},
// ...
))
or register all of them globally right away
import Vue from "vue";
import VueQrcodeReader from "vue-qrcode-reader";
Vue.use(VueQrcodeReader);
Include the following JS file:
https://unpkg.com/vue-qrcode-reader/dist/vue-qrcode-reader.umd.cjs
Make sure to include it after Vue:
<script src="./vue.js"></script>
<script src="./vue-qrcode-reader.umd.cjs"></script>
All components are automatically registered globally. Use kebab-case to reference them in your templates:
<qrcode-stream></qrcode-stream>
<qrcode-drop-zone></qrcode-drop-zone>
<qrcode-capture></qrcode-capture>
QrcodeStream
.error
event to investigate errors.barcode-detector
-> zxing-wasm
-> zxing-cpp
, and file detection issues in the highest-level repository where the problem first occurs.Support is dropped but you can downgrade to vue-qrcode-reader v3.* or lower.
That Wasm file implements the QR code detector. Unfortunately, it's not very convenient to bundle this file with the package. So by default we fetch it at runtime from a CDN. That's an issue for offline applications or applications that run in a network with strict CSP policy. For a workaround see: https://github.com/gruhn/vue-qrcode-reader/issues/354
