Angular signals vs. observables: How and when to use each
- Signals and observables are both ways to handle asynchronous data in Angular.
- Observables have been widely used in Angular for handling events, asynchronous programming, and handling multiple values over time.
- Observables come from RxJS and can be powerful but also complex to use correctly.
- Signals are a new addition to Angular and provide a simpler way to handle reactive data.
- Signals can be created and updated easily, and changes to signals automatically update the view.
- Computed signals can be used to define signals that update based on the behavior of other signals.
- Signals are well-suited for UI-related data and can be a good alternative to observables in those cases.
- Observables, on the other hand, are still useful for handling data at the service layer or when fine-grained control over asynchronous behavior is needed.
- Both signals and observables have their strengths and can be used together depending on the specific requirements of the project.
