Basic QR Code Generation

This feature allows you to generate a basic QR code by providing a URL or text string. The QR code is rendered as an image in the React component.

import React from 'react';
import QRCode from 'react-qr-code';

const App = () => {
  return (
    <div>

    </div>
  );

import React from 'react';
import QRCode from 'react-qr-code';

const App = () => {
  return (
    <div>
      <QRCode value="https://example.com" size={256} />
    </div>
  );
};

export default App;

Customizing QR Code Colors

import React from 'react';
import QRCode from 'react-qr-code';

const App = () => {
  return (
    <div>
      <QRCode value="https://example.com" fgColor="#0000ff" bgColor="#ffffff" />
