Why Your Webpack Cache Is Invalidating Every Build

Episode 19 of The Web Development Podcast with Fexingo digs into a silent performance killer: webpack cache invalidation. Lucas and Luna explore why your incremental builds are rebuilding entire bundles from scratch, how a simple loader misconfiguration can throw away cache hits, and the one trick — deterministic hashing with content hashes — that shaved 60 seconds off a real-world CI pipeline. They walk through cache busting gone wrong, the difference between module and chunk hashes, and why you should never let timestamps into your build output. No jargon dumps: just a specific, actionable fix for a problem every webpack user has felt but few debug. Plus, a quick moment on how listener support keeps this show ad-free. #Webpack #WebpackCache #BuildPerformance #JavaScript #CI/CD #DevTools #SoftwareEngineering #Frontend #WebDev #CodeOptimization #IncrementalBuilds #CacheInvalidation #Technology #WebDevelopment #FexingoBusiness #BusinessPodcast #WebDevPodcast #Fexingo Keep every episode free: buymeacoffee.com/fexingo
