WebSockets & Real-Time Communication

How should you handle WebSocket reconnection in production applications?

class WebSocketClient {
    constructor(url, options = {}) {
        this.url = url;
        this.options = {
            reconnectInterval: 1000,
            maxRetries: 5,
            ...options
        };
        this.retries = 0;
        this.connect();
    }

    connect() {
        this.ws = new WebSocket(this.url);
        this.ws.onclose = this.handleClose.bind(this);
    }

    handleClose() {
        if (this.retries < this.options.maxRetries) {
            this.retries++;
            setTimeout(() => {
                this.connect();
            }, this.options.reconnectInterval * Math.pow(2, this.retries - 1));
        }
    }
}

Always create new connection immediately
Use exponential backoff and retry limits
Production WebSocket reconnection should implement several best practices: 1) Use exponential backoff to prevent server flooding, 2) Set maximum retry attempts, 3) Implement connection state tracking, 4) Handle cleanup and resource management, 5) Consider connection quality before reconnecting. The code demonstrates a robust implementation using exponential backoff (2^n * base interval) and retry limits, wrapped in a reusable class.
Ignore disconnections
