How APIs Use WebSockets for Persistent Connections

Episode 51 of The API Podcast digs into WebSockets — the protocol that flips the typical request-response model on its head. Lucas and Luna walk through a concrete example: how a real-time dashboard for a logistics startup cut latency from three seconds to under a hundred milliseconds by switching from polling to a persistent WebSocket connection. They discuss when WebSockets make sense (and when they don't), the upgrade handshake mechanics, how to handle reconnection gracefully, and why companies like Slack and Trello rely on them for live collaboration. If you want to understand the trade-offs between REST polling, Server-Sent Events, and full-duplex sockets, this episode gives you the mental model to make the call. #WebSockets #RealTimeAPI #PersistentConnections #APIProtocols #Latency #Polling #ServerSentEvents #FullDuplex #Slack #Trello #Logistics #TechPodcast #TheAPIPodcast #FexingoBusiness #BusinessPodcast #DeveloperTools #WebDevelopment #DataStreaming Keep every episode free: buymeacoffee.com/fexingo
