RxJS Tutorial – Angular Observables


Before you can dive into the world of RxJS, you need to know about its operators. RxJS has a large collection of operators that are suitable for a wide variety of use cases. Fortunately, there are plenty of resources available to help you learn them all. In this RxJS tutorial, we will cover some of the most important ones.

Observables in Angular

Observables are a new way of managing async data in Angular applications. An observable is a data type that emits multiple values and can be triggered by user input. In Angular, observables are used extensively, including in the event system and HTTP service.

Observables are declarative objects that maintain a list of dependencies and can be used to manage events and handle multiple values. Observables are similar to the publish/subscribe design pattern. They provide support for passing messages between parts of a single-page application. They also serve as a way to handle multiple values, asynchronous programming, and event-handling processes.

In Angular, observables can be used to handle various actions on the page, such as handling user input and AJAX requests. Observables also allow developers to create custom data structures. These data structures can be used in various parts of an application, from the routing code to the view.
