• Livewire Components: Responsible for handling user interactions and updating the UI in real-time.

Backend

• PHP Laravel: Provides the backend framework for handling HTTP requests, database interactions, and business logic.
• Eloquent ORM: Laravel's ORM is used for interacting with the database and managing application data.

Database

• MYSQL Database used for storing user information and chat messages.

Pusher WebSocket

Configuration Options

The application offers various configuration options that can be adjusted according to specific requirements. These options include:

Troubleshooting

If you encounter any issues during installation or usage, consider the following troubleshooting steps:

• Check Environment Configuration: Ensure that all environment variables are correctly set up, especially database connection settings.
• Review Error Logs: Check Laravel's error logs (storage/logs/laravel.log) for any error messages or exceptions.
• Clear Cache: Sometimes, clearing the application cache (php artisan cache:clear) can resolve unexpected behavior.
