Once the package is installed, you can import it into your project using the require statement:
const qr = require('qr-code');
With the qr package imported, you can now generate a QR code for Wi-Fi access. Here's an example:
const wifi = {
ssid: 'MyNetwork',
password: 'MyPassword',
type: 'WPA',
};
const qrCode = qr.create(JSON.stringify(wifi), { type: 'svg' });
console.log(qrCode);
In the example code above, we define a JavaScript object called "wifi" that contains the SSID, password, and encryption type of the Wi-Fi network. We then pass this object to the qr.create() function, along with the desired output type (in this case, SVG).
Finally, we log the generated QR code to the console. You can then use this code to display the QR code on your website, print it out, or share it with others.
By using the QR Code npm package with Node Package Manager (npm), generating and using QR codes for Wi-Fi access becomes a breeze. With just a few lines of code, you can provide a convenient way for users to connect to your Wi-Fi network.

const qrCode = require('qr-code-npm');
const paymentDetails = {
recipient: 'John Doe',
accountNumber: '1234567890',
amount: 100
};
const qrData = qrCode.generate(JSON.stringify(paymentDetails));
console.log(`QR Code for payment option: ${qrData}`);
In the example above, we create a paymentDetails object that contains the recipient's name, account number, and payment amount. We then use the generate function from the qr-code-npm package to generate a QR code from the payment details. Finally, we log the generated QR code data to the console.
By using the QR Code npm package, you can easily integrate payment options into your node.js application and provide a convenient and secure way for users to make payments.
