Usage

The Vue Barcode Reader works out of the box by just including it.

Using Video Camera

Once a stream from the users camera is loaded, it's displayed and continuously scanned for barcodes. Results are indicated by the decode event.

import { StreamBarcodeReader } from "vue-barcode-reader";

In your template you can use this syntax:

<StreamBarcodeReader @decode="onDecode" @loaded="onLoaded"></StreamBarcodeReader>

Scanning from Image

The component renders to a simple file picker input element. Clicking opens a file dialog. On supporting mobile devices the camera is started to take a picture. The selected images are directly scanned and positive results are indicated by the decode event.

import { ImageBarcodeReader } from "vue-barcode-reader";

In your template you can use this syntax:

<ImageBarcodeReader @decode="onDecode" @error="onError"></ImageBarcodeReader>

methods: { onDecode (result) { console.log(result) } }

Events

The library emits the following events:

loaded
