Vue Js Qr Code Reader

In today’s technological world, QR (Quick Response) codes have become an increasingly popular way to store and share data. With the rise of mobile devices, it’s important for web developers to create easily scannable codes to share information quickly and efficiently. Vue Js offers a great solution for creating QR code readers that can be easily integrated into your website or application.

What is Vue Js?

Vue.js is a popular JavaScript framework that provides an easy-to-use toolset for building complex, scalable applications. It offers many benefits such as two-way data binding, a virtual DOM, and a straightforward syntax that makes it easy to learn and use.

How to Create a QR Code Reader with Vue Js?

Creating a QR code reader with Vue Js is easy and can be done in just a few steps. First, you’ll need to install the “qrcode-reader” package using npm. Once you have the package installed, you can create a new Vue component for your QR code reader and import the necessary components from the package.

Step 1: Install the qrcode-reader Package

To install the “qrcode-reader” package, open your terminal and run the following command:

npm install qrcode-reader

Step 2: Set up the Vue Component

Next, you’ll need to create a new Vue component for your QR code reader. In your Vue component, you’ll import the qrcode-reader package, as well as any necessary components, such as the Vue QR Reader component. Here’s an example:

<template>
  <div>
    <vue-qr-reader ref="reader" @decode="onDecode"></vue-qr-reader>
    <p>{{result}}</p>
  </div>
</template>

<script>
import VueQrReader from 'vue-qr-reader';

export default {
  components: {
    VueQrReader
  },
  data() {
    return {
      result: ''
    }
  },
  methods: {
    onDecode(result) {
      this.result = result;
    }
  }
}
</script>

In this example, we’re using the “Vue QR Reader” component from the “qrcode-reader” package to create our QR code reader. When a code is scanned, the “decode” event is triggered, and we update the “result” data property with the decoded data.
