Google has officially released Angular 19, the latest version of its popular TypeScript-based web development framework. This update brings significant enhancements to server-side rendering (SSR) and developer productivity.

One of the key features of Angular 19 is incremental hydration, which allows developers to annotate parts of a template to be loaded lazily on specific triggers. This feature, along with the new route-level render mode, provides more control over SSR and improves application performance.

Additionally, Angular 19 enables event replay by default, addressing a common issue in server-side rendered applications where there is a gap between user events and the browser's response. Other notable improvements include hot module replacement (HMR) for styles, experimental support for template HMR, and a new compiler flag to enforce the use of modern APIs.

These updates are expected to significantly boost developer productivity and improve the overall development experience in Angular. With Angular 19, developers can now focus on building faster, more efficient, and scalable applications.
