Why Your WebSocket Backpressure Is Silently Crashing Your Server

Episode 30 of The Web Development Podcast with Fexingo dives into a common but invisible backend problem: missing WebSocket backpressure. Lucas and Luna explain why most WebSocket servers lack built-in flow control, how this silently grows memory buffers until a crash, and what a real-world fix looks like. They walk through a concrete case: a chat server that held 200MB of pending messages per client, triggered a 500ms GC pause, and took down a production app. You'll learn how to detect backpressure failure using a single Node.js metric and why a simple 'isWritable' check can prevent the entire class of failure. No jargon — just a practical pattern you can apply today. #WebSocket #Backpressure #NodeJs #FlowControl #MemoryLeak #GarbageCollection #ServerCrash #RealTimeApps #ChatServer #WritableStream #DrainEvent #ProductionDebugging #WebDev #Technology #FexingoBusiness #BusinessPodcast #WebDevPodcast #Episode30 Keep every episode free: buymeacoffee.com/fexingo
