This is a WhatsApp bot project for promotion alerts developed in Node.js using the WhatsappWebJS library to interact with the WhatsApp API and Kafka for messaging.

This bot notifies and tracks product promotions via WhatsApp groups or polls. Developed in Node.js with the WhatsappWebJS library, it uses Kafka for messaging, Docker for containers, and PostgreSQL as the database.

Prerequisites

Docker and a stable internet connection.

Usage

1. Create a .env file at the root of the project with the following content:

   POLL_URL='{{POLL URL}}' (if applicable)
   KAFKA_TOPIC=WHATSAPP-RESPONSES
   POLL_INTERVAL=300000
   GROUP_ID=TEST-GROUP
   
   DB_USER={{DBUSER}}
   PASSWORD={{DATABASE_PASSWORD}}
   HOST=postgres
   DATABASE={{DATABASE}}
   

2. Start the WhatsApp bot: docker compose up --build.
3. Scan the QR code displayed in the terminal using WhatsApp on your mobile device. 3.1 (Tip) If any of the QR code services do not work, you can restart only the respective container.
4. Join groups to analyze messages or configure a POLL.
