Angular 22 makes three feature areas stable: Signal Forms, Angular Aria, and asynchronous signals, including resource() and httpResource(). Bytes issue 494, published June 9, 2026, sums up the release with the phrase “stability and innovation.” That is the newsletter’s framing, not an official Angular slogan.
What Angular 22 marks stable
Angular’s official v22 release page identifies three areas as stable: Signal Forms, Angular Aria, and Asynchronous Signals. Stability means these are no longer presented as experimental features; it does not mean every application should adopt them without evaluating its own needs.
- Signal Forms: Angular’s signal-based approach to working with forms.
- Angular Aria: interaction patterns that developers can use when building custom-styled components. Angular’s roadmap says Angular Aria was promoted to stable in v22.
- Asynchronous Signals: APIs such as
resource()andhttpResource()for representing asynchronous data in Angular’s signal model.
How resources handle asynchronous data
Angular describes a Resource as an asynchronous dependency delivered through signals. A resource exposes information such as its current value, status, error, and loading state, so the rest of an application can react to changes rather than manage every transition separately.
resource() for asynchronous reads
Use resource() when an asynchronous read depends on changing parameters. Angular’s resource guide says that when those parameters change, an outstanding loader operation is aborted. This makes resources useful for keeping displayed read data aligned with current inputs.
#1 Best Overall
Resources are intended for reads, not mutations. Do not treat resource() as an API for submitting changes or performing other write operations.
httpResource() for reactive HTTP requests
httpResource() builds a Resource for HTTP GET requests. When its signal-driven URL changes, the request updates accordingly. Angular routes these requests through its HTTP stack, including interceptors, which helps integrate reactive reads with existing HTTP behavior.
Stable APIs versus claims in the newsletter
The newsletter also describes an @service decorator for asynchronous dependency injection and experimental @boundary and @error directives for error boundaries. These descriptions are claims made by Bytes issue 494; the official Angular v22 release page cited here does not independently establish those names or behaviors. They should not be confused with the stable feature areas that Angular’s release page identifies.
