I'll help you build a WhatsApp Group Message Automation system with a full-stack approach. Let's start by setting up the project structure and implementing the core functionality.

WhatsApp Group Message Automation System

I'll create a full-stack Next.js application that handles WhatsApp automation with Baileys, using SQLite via Prisma for the database, and NextAuth for authentication.

Implementation Details

This WhatsApp Group Message Automation system includes:

1. Admin Dashboard

   • Secure login with NextAuth
   • Campaign management interface
   • WhatsApp account management with QR code login

2. Campaign Features

   • Create campaigns with custom messages
   • Upload messages via CSV
   • Schedule message sending with configurable intervals
   • Support for media attachments
   • Pause/resume/delete campaign functionality

3. WhatsApp Integration

   • QR code-based authentication
   • Support for multiple WhatsApp accounts
   • Message queue management
   • Automatic message sending with configurable intervals

4. Database Structure

   • Users for authentication
   • WhatsApp accounts for storing connection details
   • Campaigns for organizing message groups
   • Messages for tracking individual messages and their status

Technical Implementation

The system uses:

• Next.js with App Router for the frontend and backend
• Prisma with SQLite for the database
• Baileys (mocked in this implementation) for WhatsApp integration
• NextAuth for authentication
• shadcn/ui for the UI components

The WhatsApp client implementation is currently mocked but provides all the necessary interfaces for integrating with Baileys in a production environment.

Next Steps

To complete the implementation:

1. Install the required dependencies:

   npm install @prisma/client bcrypt date-fns next-auth npm install -D prisma

2. Initialize the Prisma database:

   npx prisma db push
3. Replace the mocked WhatsApp client with a real Baileys implementation
4. Set up a proper message queue system for reliable message delivery
5. Implement error handling and retry mechanisms for failed messages

I'll complete the WhatsApp automation project by implementing the remaining components and making it ready for preview. Let's add the necessary files to make the system fully functional.
