Why Your Web App Fails When the User Goes Offline

Lucas and Luna explore the hidden assumption that has broken countless web apps: persistent connectivity. They dig into the real-world failure of a major retail site's checkout flow when a user's train entered a tunnel, and walk through the surprisingly simple service-worker pattern that fixes it. Along the way, they bust the myth that offline-first means 'no internet' — it actually means graceful degradation when the network blips. With browser APIs like CacheStorage and Background Sync, you can build apps that don't silently lose user data. The episode ends with a practical tip: test your app with a 3-second network throttle and watch which features break. #OfflineFirst #ServiceWorker #CacheStorage #BackgroundSync #WebDevelopment #ProgressiveWebApp #NetworkFailure #GracefulDegradation #UserExperience #CheckoutFlow #RetailTech #JavaScript #PWA #Connectivity #WebAPIs #Technology #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
