WebSockets & Streaming Deep Dive

Overview

WebSockets enable real-time bidirectional communication.

Core Concepts

• Full-duplex (both directions simultaneously)
• Persistent connection
• Low latency vs polling

Code Examples

// OkHttp WebSocket
val webSocket = httpClient.newWebSocket(
    Request.Builder().url("wss://echo.websocket.org").build(),
    object : WebSocketListener() {
        override fun onMessage(s: WebSocket, text: String) {
            println("Received: $text")
        }
        override fun onFailure(w: WebSocket, t: Throwable, r: Response?) {
            t.printStackTrace()
        }
    }
)
webSocket.send("Hello")

Senior-Level Insights

• Reconnection logic essential
• Heartbeat/ping-pong for keep-alive
• Handle graceful disconnect
