Description:
This is the upgraded version of the gruhn’s vue-qrcode-reader that allows you to decode/parse QR code in the Vue.js 3 powered apps.
How to use it:
1. Import and register the QR Code Reader.
// globally
import { createApp } from 'vue';
import App from './App.vue'
import QrReader from 'vue3-qr-reader';
const app = createApp(App);
app.use(QrReader);
app.mount('#app')
// Locally
import { QrStream, QrCapture, QrDropzone } from 'vue3-qr-reader';
export default {
components: {
QrStream,
QrCapture,
QrDropzone
},
};2. Create a file upload field to scan all files you select.
<qr-capture @decode="onDecode" class="mb"></qr-capture>
<div class="result">
Result: {{data}}
</div>export default defineComponent({
name: 'QrCaptureExample',
components: {
QrCapture
},
setup() {
const state = reactive({
data: null
})
function onDecode(data) {
state.data = data
}
return {
...toRefs(state),
onDecode
}
}
});3. Access the device camera and continuously scans the incoming frame.
<div class="stream">
<qr-stream @decode="onDecode" class="mb">
<div style="color: red;" class="frame"></div>
</qr-stream>
</div>
<div class="result">
Result: {{data}}
</div>export default defineComponent({
name: 'QrStreamExample',
components: {
QrStream
},
setup() {
const state = reactive({
data: null
})
function onDecode(data) {
state.data = data
}
return {
...toRefs(state),
onDecode
}
}
});4. Create a drag’n’drop zone to scan all files you dropped.
<qr-dropzone class="dropzone mb" @decode="onDecode">
Drop image here.
</qr-dropzone>
<div class="result">
Result: {{data}}
</div>export default defineComponent({
name: 'QrDropzoneExample',
components: {
QrDropzone
},
setup() {
const state = reactive({
data: null
})
function onDecode(data) {
state.data = data
}
return {
...toRefs(state),
onDecode
}
}
