QR code genration taking much time and other event listener not working

[getsettalk]

Is there an existing issue for this?

• [X] I have searched the existing issues

Describe the bug

I'm genrating request to make qr code to scann it , but its taking much longer time

here is my full code please check once :

const express = require('express');
const { Client } = require('whatsapp-web.js');
const qrcode = require('qrcode');
const fs = require('fs');

const app = express();
const port = 3000;
const SESSION_FILE_PATH = 'YourSessionName.json';

let client;

// Initialize WhatsApp client
if (fs.existsSync(SESSION_FILE_PATH)) {
  // If a session file exists, load the session
  const sessionData = require(SESSION_FILE_PATH);
  client = new Client({ session: sessionData });
} else {
  client = new Client();
}

// QR Code generation and display
app.get('/', (req, res) => {
  if (!client.session) {
    client.on('qr', (qrCode) => {
      qrcode.toFileStream(res, qrCode);
    });
    client.initialize();
  } else {
    res.send('WhatsApp Web is already connected.');
  }
});

// Event listener for incoming messages
client.on('message', (message) => {
  // Handle incoming message
  console.log(`Received message from ${message.from}: ${message.body}`);

  // Send a reply
  client.sendMessage(message.from, 'Your reply goes here');
});

// Event listener for authentication
client.on('authenticated', (session) => {
  console.log('Authenticated!');
  fs.writeFileSync(SESSION_FILE_PATH, JSON.stringify(session));
});

// Start the Express server
app.listen(port, () => {
  console.log(`Server is running on port ${port}`);
});

// Start the WhatsApp client
client.initialize();

When we scanned than this code not showing console:

client.on('authenticated', (session) => {
  console.log('Authenticated!');
  fs.writeFileSync(SESSION_FILE_PATH, JSON.stringify(session));
});

Expected behavior

Qr code should be genrated fast

i forget to tell you that other event lister not working when qr code scanned but ready or authenticated event not triggered,

  client.on('authenticated', (session) => {
        // Save the session data to a file for future use
        fs.writeFileSync(SESSION_FILE_PATH, JSON.stringify(session));
        console.log("authenticated")
        // Respond to the client
        res.send('Authentication successful! You can now close this page.');
    });

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

Same Issue I am facing. How much time it will take to fix it

[themazim]

Have you tried using the last main branch version which is currenltly in alpha instead?

There a re quite a lot of fixes implemented and it works on my end.

npm i whatsapp-web.js#main

[Anshuhk]

Not working showing error "Invalid tag name "whatsapp-web.js#main" of package "whatsapp-web.js#main": Tags may not have any characters that encodeURIComponent encodes."

[themazim]

try this instead :

npm i https://github.com/pedroslopez/whatsapp-web.js#main

[Anshuhk]

same error

[themazim]

Please check your npm version and update. Should work fine:

> npm i https://github.com/pedroslopez/whatsapp-web.js#main

up to date, audited 486 packages in 3s

  run `npm fund` for details

[Anshuhk]

my npm version is 9.5.1

[themazim]

well, last resort would be to add --force but I would strongly suggest you check what's up with your npm installation.

I'm still getting this the session data as undefined

I've tested the version ^1.22.2-alpha.3 mencioned above and 1.23.1-alpha.0

Saving sessions within authenticated event worked with LegacySessionAuth strategy before the WA implemented the multidevice-enabled accounts
