Implement real-time bidirectional communication with Socket.io and ws library for chat, notifications, and live dashboards
Implement real-time bidirectional communication with WebSockets including connection management, message routing, and scaling. Use when building real-time features, chat systems, live notifications, or collaborative applications.
Expert guidance on real-time communication patterns including WebSockets, Server-Sent Events (SSE), Socket.IO, and WebRTC. Covers connection management, reconnection strategies, scaling, and real-time data synchronization. Use when "implement websocket, real-time updates, live chat, socket.io, server-sent events, live notifications, collaborative editing, presence indicators, Working with ws, Socket.IO, Pusher, Ably, websocket, realtime, socket.io, sse, live, streaming, push, collaboration" mentioned.
Tests WebSocket API implementations for security vulnerabilities including missing authentication on WebSocket upgrade, Cross-Site WebSocket Hijacking (CSWSH), injection attacks through WebSocket messages, insufficient input validation, denial-of-service via message flooding, and information leakage through WebSocket frames. The tester intercepts WebSocket handshakes and messages using Burp Suite, crafts malicious payloads, and tests for authorization bypass on WebSocket channels. Activates for requests involving WebSocket security testing, WS penetration testing, CSWSH attack, or real-time API security assessment.
WebSocket market + user data streams for Aster Futures API v3. Subscription model, stream names, listenKey. Use when implementing real-time market or user events (orders, balance, positions). listenKey = signed; see aster-api-auth-v3.
Best practices and guidelines for building real-time applications with WebSocket communication
Generate a production-grade React MQTT context for CloudSignal real-time notifications over WebSocket. Supports Clerk, Supabase, Auth0, Firebase, and custom OIDC auth providers. Use when implementing real-time notifications, live updates, job progress tracking, or WebSocket messaging with CloudSignal.
Client-side WebSocket resilience patterns: backoff with jitter, circuit breakers, heartbeat hysteresis, command acknowledgment, sequence gap detection, and mobile-aware timeouts.
Production-grade WebSocket connection management with connection limits, user-to-connection mapping, ping/pong health verification, and automatic stale connection cleanup.
WebSocket handshake, CSWSH, tooling (wsrepl, ws-harness, Burp), and common flaws. Use when apps use real-time channels, chat, notifications, or WS-backed APIs.
