Why Your API Should Use Long Polling for Real-Time Updates
from The Developer Tools Podcast with Fexingo: APIs, Infrastructure, and Software for Engineers Hosted by Fexingo
Most developers reach for WebSockets when their app needs real-time updates. But for a huge class of use cases, long polling stays simpler, more robust, and far easier to scale. In this episode, Lucas and Luna dig into a real-world example: a ride-hailing app that ditched WebSockets for long polling after their infrastructure kept crumbling. They explain how long polling works, why it beats WebSockets for many server-driven scenarios, and when it's actually a bad idea. You'll learn the precise trade-offs between connection management, latency, and load, and how to use HTTP caching to make long polling even more efficient. Whether you're an engineer building your first real-time feature or a tech lead choosing between protocols, this episode gives you a concrete mental model. Plus, Lucas shares the one question he always asks before choosing a real-time strategy — it'll change how you think about the problem. #LongPolling #APIRealTime #WebSockets #HTTP #ServerPush #Scalability #RideHailing #Caching #ETag #APIArchitecture #BackendEngineering #DevTools #SoftwareEngineering #TechDecisions #BusinessAndTech #FexingoBusiness #BusinessPodcast #TechPodcast Keep every episode free: buymeacoffee.com/fexingo
