WhatsApp Bot

This project is a simple WhatsApp bot built using the whatsapp-web.js library. The bot automates sending a specified message to a target contact repeatedly.

Features

• QR code-based authentication using whatsapp-web.js and LocalAuth.
• Sends a predefined message to a specified contact.
• Logs various client states, including authentication status and connection state.

Requirements

• Node.js (v14 or later)
• A WhatsApp account

Installation

1. Clone the repository:

   git clone https://github.com/AbubakarWebDev/whatsapp-bot-nodejs
   cd https://github.com/AbubakarWebDev/whatsapp-bot-nodejs

2. Install the dependencies:

   npm install whatsapp-web.js qrcode-terminal

Configuration

1. Open the source code (index.js or equivalent).
2. Set the following variables:
   • chatName: Replace <--- Person Contact Name ---> with the contact name as it appears in your WhatsApp chat list.
   • msg: Replace "Hello How Are You?" with the message you want to send.

Usage

1. Start the bot:

   node index.js

2. Scan the QR code displayed in the terminal using your WhatsApp app to authenticate.

3. Once authenticated, the bot will:

   • Search for the target contact in your chat list.
   • Send the specified message repeatedly to the contact (1000 times).

Code Overview

Main Logic

• QR Code Authentication: The bot generates a QR code for authentication. You need to scan this code using the WhatsApp app.
• Message Sending: Once authenticated and the client is ready, the bot searches for the target contact by name and sends the specified message repeatedly.

Event Handlers

• client.on('qr', qr): Generates and displays the QR code for authentication.
• client.on('ready'): Triggered when the client is ready to send messages.
• client.on('message', message): Logs incoming messages.
• client.on('disconnected', reason): Logs the reason for disconnection.

Notes

• The bot uses the LocalAuth strategy to persist the session locally, so you won’t need to scan the QR code again unless the session is cleared.
• Ensure the contact name in chatName matches exactly as it appears in WhatsApp.
