How to get the number of sender in web whatsapp JS

[frank lantern]

I want to get the number of new sender and save it in a text file. Is this possible to achieve? any help would be appreciated. Thanks

if (!(sender in userInfo)) {
    console.log("This is a new user.");

    // Create a text file and write the sender number to it
    fs.writeFile('new_users.txt', sender, (err) => {
        if (err) throw err;
        console.log('Sender number added to new_users.txt');
    });

    client.sendMessage(sender, greetings, { mentions: [contact] });
    
    userInfo[sender] = {
        "mode": "mode 1",
        "currentStage": "begin",
        "voice_id": "base",
        "elevenLabsLatency": 3,
    };
    
    return;
}```

console.log(msg.getContact());

You can see all properties for the contact.

can we use this to get the number and save it in txt?

You need to see this fix first https://github.com/pedroslopez/whatsapp-web.js/pull/2325

You can do whatever you want if the information.

Thanks I will look into it

        console.log("This is new user.");
        message.getContact().then(contact => {
            console.log("The contact is -> " + contact.number);
            contact.number = contact.number.split('@')[0];
            //save the contact number in the in txt file
            fs.appendFile('contacts.txt', contact.number + '\n', function (err) {
                if (err) throw err;
                console.log('Saved!');
            });

        });

btw why havent they merged it yet and how can I merge it on mine?

[oblique lance]

I don't know why they didn't merge to the main branch, but you can do all the modifications on your code.

im kind of a noob, no idea how to modify the library. (my instinct tells me to clone it and modify it but i am not well versed on nodejs enough to know how to even point it to the merged lib) So I think i will just wait for them to merge it 😅

[frank lantern]

Do we have any idea how long would it actually take?
