WebSockets & Real-Time Communication

What should be considered when implementing WebSocket message queuing?

class WebSocketQueue {
    constructor() {
        this.queue = [];
        this.processing = false;
    }

    enqueue(message) {
        this.queue.push(message);
        if (!this.processing) {
            this.processQueue();
        }
    }

    async processQueue() {
        if (this.queue.length === 0) {
            this.processing = false;
            return;
        }

        this.processing = true;
        const message = this.queue.shift();

        try {
            await this.sendMessage(message);
            setTimeout(() => this.processQueue(), 50); // Rate limiting
        } catch (error) {
            this.handleError(error, message);
        }
    }
}

Send messages immediately
Store messages indefinitely
Implement rate limiting and error handling
WebSocket message queuing should consider: 1) Rate limiting to prevent flooding, 2) Message prioritization, 3) Error handling and retries, 4) Queue size limits, 5) Message persistence for critical data, 6) Order preservation when needed, 7) Memory management, 8) Connection state awareness, 9) Batch processing capabilities. The code shows a queue implementation with rate limiting and error handling.
Discard unsent messages
