Get Started
Forms and selectorless components are major updates that are still under development in Angular.
Signal forms are an upcoming API designed to provide more reactive and streamlined forms management. Selectorless components are also being developed as a future improvement to simplify component usage in forms, reduce boilerplate, and make Angular templates cleaner and more intuitive.
Reactive forms now offer better type inference, making it harder to accidentally assign the wrong data type to a control.
Asynchronous validators can now cancel outdated requests automatically, improving performance in form-heavy applications.
Angular 20 allows custom error mapping for cleaner form validation messages.
Angular 20 introduces a game-changing approach to component creation with the stabilization of the Dynamic Component Creation API. This new API empowers developers to create components dynamically at runtime in a type-safe and declarative manner.
With the createComponent function, you no longer need to rely on ViewContainerRef or ComponentFactoryResolver.
Instead, Angular 20 handles dependency injection, change detection, lifecycle hooks, and content projection automatically, streamlining the entire process. This enhancement not only reduces boilerplate code but also makes your dynamic component logic more readable and maintainable.
Developers have now gained access to several new and improved APIs designed to enhance both performance and the overall developer experience.
One of the standout additions is the experimental httpResource API, which introduces a Signal-based approach to handling HTTP requests. This modernizes how asynchronous data is managed, making it easier to build reactive, data-driven applications.
The Effect API is now fully stabilized in Angular 20. This API allows developers to automatically respond to changes in signals, making it ideal for handling side effects such as debugging, persisting state, or updating databases in real time. The Effect API also supports cleanup operations, which helps prevent memory leaks and keeps your applications running smoothly.
This stabilization demonstrates Angular’s ongoing commitment to delivering robust tools for modern web development.
By embracing these updates, Angular 20 ensures that developers have the tools they need to build scalable, maintainable, and high-performance applications that meet the demands of modern web development.
Angular Material continues to be a cornerstone for building visually appealing and accessible Angular applications.
In Angular 20, the library receives notable updates, particularly to the button component, which now aligns more closely with Google’s Material 3 (M3) design specifications. This ensures a more consistent and modern look across your application’s UI. These updates not only improve the appearance and responsiveness of your UI but also help developers create accessible, feature-rich applications more efficiently.
