Login qrcode whatsapp-web.js on terminal

To log in with WhatsApp Web using whatsapp-web.js on the terminal, you can follow these steps:

1. First, you need to install whatsapp-web.js using npm. Open your terminal and navigate to your project folder. Then, run the following command:

npm install whatsapp-web.js

2.Once whatsapp-web.js is installed, you can create a new JavaScript file (for example, index.js) and add the following code:

const qrcode = require('qrcode-terminal');
const { Client } = require('whatsapp-web.js');
const client = new Client();

client.on('qr', (qr) => {
	qrcode.generate(qr, { small: true });
});

client.on('ready', () => {
	console.log('Client is ready!');
});

client.initialize();

3. In the code above, we first import qrcode-terminal and whatsapp-web.js. Then, we create a new Client object and attach two event listeners to it: one for the QR code and another for when the client is ready.

4. To display the QR code in the terminal, we use the qrcode-terminal library and call the generate method with the QR code passed as an argument.

5. Finally, we initialize the client by calling the initialize method.

6. Run the index.js file in your terminal using the following command:

node index.js

7. You will see a QR code displayed in your terminal. Scan this QR code using your WhatsApp mobile app to log in to WhatsApp Web.

Once you scan the QR code, you should see a message in the terminal saying that the client is ready. From here, you can use the client object to send and receive messages, send files, and perform other actions on WhatsApp Web.
