The Developer Tools Podcast with Fexingo · 2026-07-19 · 8 min
Episode 120 of The Developer Tools Podcast explores why REST-based polling is outdated for real-time features like live dashboards and collaborative editing. Lucas and Luna break down how GraphQL subscriptions use WebSocket connections to push only changed data, reducing bandwidth by up to 90% compared to polling. They walk through a real-world case: a logistics company that cut server costs by 40% after switching from REST polling to subscriptions for their shipment tracking dashboard. The hosts also discuss trade-offs: connection state management, backpressure, and when to fall back to polling. If you've ever built a feature that needed 'live' updates, this episode explains why subscriptions are the pattern you're missing. #GraphQL #Subscriptions #WebSockets #RealTime #API #Backend #DeveloperTools #BusinessAndTechnology #SoftwareEngineering #FexingoBusiness #BusinessPodcast #LiveUpdates #Polling #Performance #Scalability #Logistics #CaseStudy #DevTools Keep every episode free: buymeacoffee.com/fexingo
