16 - Angular 19 Frontend: Modern Architecture for a Complex App

Play The Event frontend architecture: standalone components, Signals with BaseStore, SSR with Express, 27 lazy-loaded modules, 21 languages, 5 advanced UI libraries and testing.

What you'll learn

• Signals simplify state: Moving from RxJS-heavy templates to Signals reduced complexity and improved readability
• Lazy loading is essential at scale: 27 modules keep the initial bundle under 200KB gzipped
• SSR pays dividends: Pre-rendered pages improve both SEO and perceived performance, especially on mobile
• Internationalization must be planned early: Adding 21 languages retroactively would have been far more expensive
• Mobile-first is not optional: Most event participants access the platform from their phones during the event itself
