Automate your whatsapp using nodejs

WhatsApp is a popular messaging app with over a billion users worldwide. Although it has a simple interface, it is a powerful tool that can be used for a variety of purposes.

One of the great things about WhatsApp is that it can be easily automated using node.js. This can be useful for a number of reasons, such as sending automated messages to a group of people, or sending reminders and alerts.

To automate WhatsApp using node.js, you will need to use a package called "whatsapp-web.js". This package allows you to interact with the WhatsApp Web API, which is the same API that the WhatsApp desktop app uses.

Once you have installed the whatsapp-web.js package, you can use the following code to send a message to a specific WhatsApp contact:

var whatsapp = require('whatsapp-web.js');

whatsapp.sendMessage('+11234567890', 'Hello, world!');

This code will send the message "Hello, world!" to the WhatsApp contact with the phone number +11234567890.

You can also use the whatsapp-web.js package to send messages to a group of WhatsApp contacts. To do this, you will need to create a group on WhatsApp, and then add the phone numbers of the contacts that you want to add to the group. Once you have done this, you can use the following code to send a message to the group:

var whatsapp = require('whatsapp-web.js');

whatsapp.sendMessageToGroup('GROUP-ID', 'Hello, world!');

Replace GROUP-ID with the actual ID of the group that you created. This code will send the message "Hello, world!" to all the contacts in the group.

You can also use the whatsapp-web.js package to send messages to all your WhatsApp contacts. To do this, you can use the following code:

var whatsapp = require('whatsapp-web.js');

whatsapp.sendMessageToAllContacts('Hello, world!');

This code will send the message "Hello, world!" to all your WhatsApp contacts.

You can also use the whatsapp-web.js package to create a bot that will respond to messages that you receive on WhatsApp. To do this, you will need to create a file called "bot.js" and add the following code to it:

var whatsapp = require('whatsapp-web.js');

whatsapp.createBot('BOT-ID', function (message) {

if (message.body == 'hello') {

whatsapp.sendMessage(message.from, 'Hello, world!');

}

});

Replace BOT-ID with the actual ID of the bot that you want to create. This code will create a bot that will respond to the message "hello" with the message "Hello, world!".

You can also use the whatsapp-web.js package to schedule messages to be sent at a later time. To do this, you will need to use the following code:

var whatsapp = require('whatsapp-web.js');

whatsapp.scheduleMessage('+11234567890', 'Hello, world!', '2018-01-01T12:00:00.000Z');

This code will send the message "Hello, world!" to the WhatsApp contact with the phone number +11234567890 at 12:00pm on 1st January 2018.

You can also use the whatsapp-web.js package to send messages with attachments. To do this, you will need to use the following code:

var whatsapp = require('whatsapp-web.js');

whatsapp.sendMessageWithAttachment('+11234567890', 'Hello, world!', './file.jpg');

This code will send the message "Hello, world!" to the WhatsApp contact with the phone number +11234567890, with the attachment "file.jpg" being included.

You can also use the whatsapp-web.js package to create a group chat. To do this, you will need to use the following code:

var whatsapp = require('whatsapp-web.js');

whatsapp.createGroupChat('GROUP-NAME', ['+11234567890', '+11234567891']);

Replace GROUP-NAME with the actual name of the group chat that you want to create, and replace +11234567890 and +11234567891 with the phone numbers of the contacts that you want to add to the group chat. This code will create a group chat with the name "GROUP-NAME" and the contacts +11234567890 and +11234567891.

You can also use the whatsapp-web.js package to leave a group chat. To do this, you will need to use the following code:

var whatsapp = require('whatsapp-web.js');

whatsapp.leaveGroupChat('GROUP-ID');

Replace GROUP-ID with the actual ID of the group chat that you want to leave. This code will leave the group chat with the ID "GROUP-ID".
