Custom Operators
Explore how to create custom operators in RxJS to enhance data transformation and reuse logic in reactive programming. Understand how operators work as Observables and implement cloning operators to manage object references safely within streams. This lesson enables you to extend RxJS functionality tailored to your app's needs.
We'll cover the following...
Now that you know the majority of RxJS operators that exist out there, you might wonder if you can create your own custom operators.
The answer is yes! And it’s very easy.
Every operator is an Observable, which applies to a source Observable. The source Observable might be the original source or an Observable released by the operator before the current operator. With this knowledge, let’s first have a look at a problem, and create a custom operator that would help us solve it.
Publishing and modifying objects
The following scenario illustrates an object that contains data from a submitted form, flowing through a pipeline to an Observer. The Observer’s goal ...
