Angular 19 introduces features that improve developer experience and performance.
Key features to explore in version 19 include enhanced Server Side Rendering, signal-based Resource API, view transitions with withViewTransitions, and Incremental Hydration.
Developers can now explicitly configure how specific routes are rendered with the Server Routes Configuration feature.
The newly introduced signal-based Resource API allows developers to manage application state and HTTP requests more effectively with signals, providing a reactive paradigm for state management.
View Transitions with withViewTransitions enables smoother transitions between routes by running the route activation and deactivation inside document.startViewTransition.
Incremental Hydration in version 19 allows developers to annotate parts of the template with the already-familiar @defer syntax, instructing Angular to render them on specific triggers lazily.
Angular v19 supports hot module replacement (HMR) for styles out of the box and enables experimental support for template HMR, making it easy for developers to update their styles and templates without needing a page refresh.
Upgrading Angular to version 19 provides a variety of new features that can greatly benefit Angular projects.
Exploring these enhancements can improve the performance, usability, and maintainability of Angular applications.
The article provides examples of how to update existing Angular applications to utilize these features and where to get assistance if needed.
