What We’re Building Today By the end of this lesson you’ll have a production-grade React frontend that does five things your users will feel immediately: Splits code so users only download what they actually need Lazy-loads routes and heavy components on demand Cuts the initial bundle size below 200KB Installs a Service Worker for offline caching and instant repeat visits Monitors real-user performance through a live dashboard showing Core Web Vitals, resource timings, and bundle stats This lesson is the client-side half of the performance story you started yesterday. Yesterday you made the backend fast. Today you make sure that speed actually reaches the user’s screen.
