How Your Webpack Dev Server Memory Leaks Kill Overnight Builds

Lucas and Luna dive into a silent productivity killer: memory leaks in webpack-dev-server that accumulate over long development sessions. They trace the problem to unclosed WebSocket connections from Hot Module Replacement, showing how a single missed cleanup in the dev server's event loop can balloon RAM usage to 4GB after eight hours. The episode walks through real debugging steps using Chrome DevTools Memory tab and the 'detached DOM nodes' filter, then explains the fix: a custom plugin that hooks into the 'done' compiler hook to force-close stale sockets. Listeners will walk away with a concrete script they can drop into their webpack config today to keep their dev server lean during all-day coding marathons. #WebpackDevServer #MemoryLeak #HotModuleReplacement #WebSocket #ChromeDevTools #DetachedDOMNodes #DevServer #JavaScript #Performance #Frontend #Debugging #Technology #WebDevelopment #FexingoBusiness #BusinessPodcast #Coding #NodeJS #BuildTooling Keep every episode free: buymeacoffee.com/fexingo
