How APIs Use WebSockets for Real-Time Updates Over Polling
from The API Podcast with Fexingo: REST, GraphQL, and Modern Web APIs Hosted by Fexingo
Episode 155 of The API Podcast: Lucas and Luna unpack why WebSockets beat REST polling for real-time apps. They trace the handshake that upgrades an HTTP request to a full-duplex socket, the reconnection logic that keeps dashboards alive, and the backpressure problem that trips up chat and trading UIs. Using a hypothetical live auction app as a running case, they show how a single persistent connection replaces dozens of HTTP calls per minute — and why that's not always the right trade. They also weigh WebSocket's downside: no built-in authorization on each message, harder caching, and the operational pain of connection state. By the end, you'll know when to pick WebSockets over SSE or plain polling, and what to watch for in production. Tune in for a clear, practical breakdown of one of the web's most powerful API tools. #WebSockets #RealTimeAPIs #API #Polling #ServerSentEvents #FullDuplex #Latency #Backpressure #Reconnection #LiveUpdates #TechPodcast #WebDevelopment #APIArchitecture #FexingoBusiness #BusinessPodcast #LucasAndLuna #APIPodcast #DeveloperTools Keep every episode free: buymeacoffee.com/fexingo
