WebSocket Client JavaScript Implementation

Below is an improved and concise implementation of a WebSocketClient class. It handles connection management, reconnection logic, heartbeat mechanisms, and message queuing, making it robust for real-world applications.

WebSocket Client Class Implementation

Key Features

1. Connection Management:

• Handles onopen, onclose, and onerror events gracefully.
• Reconnects automatically using exponential backoff.

2. Heartbeat Mechanism:

• Sends periodic heartbeat messages to keep the connection alive.
• Detects and handles heartbeat timeouts.

3. Reconnection Logic:

• Reconnects when the connection drops unexpectedly, with configurable limits.
• Stops reconnection attempts after reaching a maximum number of attempts.

4. Message Queue:

• Caches messages if the connection is closed and sends them once reconnected.

5. Customizable:

• Options like onOpen, onMessage, and onError allow for flexible callbacks.

Usage Example

Summary

This WebSocketClient class provides a robust solution for handling WebSocket connections, ensuring stability through reconnection, heartbeat, and message queuing. It is well-suited for real-time applications requiring persistent communication.
