Lucas and Luna tackle a silent performance killer in Node.js applications: memory leaks that don't crash your app but gradually consume CPU and degrade throughput. They walk through a real case where a forgotten `setInterval` combined with a closure referencing a large data structure caused a 40 percent CPU increase over three weeks. You'll learn how to spot the pattern using heap snapshots and why tools like `clinic` or Chrome DevTools' memory tab matter more than just checking memory usage. The episode ends with practical strategies: scoping timers, weak references, and monitoring for gradual growth rather than static thresholds. #NodeJS #MemoryLeak #CPUProfiling #Performance #Backend #ClinicJS #ChromeDevTools #HeapSnapshot #JavaScript #ServerSide #Debugging #setInterval #WeakRef #GarbageCollection #Technology #FexingoBusiness #BusinessPodcast #WebDev Keep every episode free: buymeacoffee.com/fexingo
