A QR code (abbreviated from Quick Response code) is a type of matrix barcode (or two-dimensional barcode) first designed in 1994 for the automotive industry in Japan. A barcode is a machine-readable optical label that contains information about the item to which it is attached. In practice, QR codes often contain data for a locator, identifier, or tracker that points to a website or application. A QR code uses four standardized encoding modes (numeric, alphanumeric, byte/binary, and kanji) to store data efficiently; extensions may also be used.
Generating QR codes in React has never been easier. There are a few libraries available but the one we will be using in this article is qrcode.react.
Installation
Run the following to install qrcode.react in your React project:
$ yarn add qrcode.react
# or, using NPM:
$ npm install --save qrcode.reactGetting Started
Adding a QR code to your React app is just as easy as:
import React from 'react';
import QRCode from "qrcode.react";
export function MyComponent() {
return (
<QRCode value="https://www.npmjs.com/package/qrcode.react" />
);
}Under the Hood
QRcode.react is basically a React wrapper for the qr.js library. If you’re interested in implement QR codes in JavaScript I would recommend looking into that library as well. It’s very popular and is used by all of the other QR code generating React libraries.
