Angular 19 introduces powerful improvements in performance, server-side rendering, reactivity, and security.
Incremental Hydration improves server-side rendered (SSR) app loading and interactivity by allowing progressive element updates.
Route-Level Rendering Configuration enables fine-tuning rendering options for each route, including server-side rendering (SSR), static pre-rendering, or client-side rendering (CSR).
Signal-Based API for State Management introduces signals as a cleaner, reactive alternative to traditional Observables or NgRx for local state management in Angular 19.
Standalone Components by Default reduces boilerplate and simplifies component structure by making all new Angular 19 components standalone, removing the need for NgModules.
