WebSockets & Real-Time Communication

What are the best practices for implementing WebSocket event handling?

class WebSocketEventHandler {
    constructor() {
        this.handlers = new Map();
        this.setupWebSocket();
    }

    setupWebSocket() {
        this.ws.onmessage = (event) => {
            try {
                const { type, payload } = JSON.parse(event.data);
                this.dispatch(type, payload);
            } catch (error) {
                this.handleError(error);
            }
        };
    }

    on(eventType, handler) {
        if (!this.handlers.has(eventType)) {
            this.handlers.set(eventType, new Set());
        }
        this.handlers.get(eventType).add(handler);
        return () => this.off(eventType, handler);
    }

    dispatch(type, payload) {
        const handlers = this.handlers.get(type);
        if (handlers) {
            handlers.forEach(handler => {
                try {
                    handler(payload);
                } catch (error) {
                    this.handleError(error);
                }
            });
        }
    }
}

Handle all events in one function
Ignore event handling
Implement structured event handling with error management
Best practices for WebSocket event handling include: 1) Structured event dispatching system, 2) Type-safe event handling, 3) Error boundary implementation, 4) Event queuing when needed, 5) Handler cleanup management, 6) Event validation and sanitization, 7) Performance monitoring of handlers, 8) Timeout handling for long-running handlers, 9) Event logging and debugging capabilities, 10) Memory leak prevention through proper cleanup.
