[FEAT]: Add Pusher for Real Time Events and Notifications.

[edwinedjokpa]

Description

Pusher Integration for Real-time Communication in the application. This will allow the app to push real-time events (e.g., notifications, live updates) to users without needing them to poll the server continuously.

Acceptance Criteria

• Pusher service is set up and connected to the application.
• Real-time events can be triggered from the server.
• Users can listen for events from the server using Pusher.
• Messages or events are broadcasted to the appropriate channels.
• Error handling for Pusher integration is implemented (e.g., failure to send events).

Purpose

The integration of Pusher will enable the application to send real-time events to connected users. This is useful for applications that require instant notifications and other updates.

Requirements

• Pusher Account: You need to create a Pusher account and obtain your app_id, key, secret, and cluster.
• Pusher Library: Install the Pusher client and server SDKs to interact with the service.
• App Integration: Use the Pusher service to broadcast events from the server side.
• Client-Side Integration: Implement Pusher on the frontend (React, Vue, etc.) to listen to the real-time events.

Expected Outcome

Server-Side: The server will be able to send real-time updates to any connected users using the Pusher service.
Client-Side: Users will automatically receive notifications or updates without needing to refresh the page, resulting in a seamless real-time experience.

Additional Context

• Ensure that channels are appropriately created and accessible.
• Consider implementing presence channels for more advanced real-time features, like knowing who is online or tracking user activity.
• Pusher also offers additional features like WebSockets and push notifications that could be used depending on your application needs.
• Pusher requires an active internet connection for broadcasting events. In production, make sure to handle network failures or service downtime gracefully.
