Pipes and Operators
Explore how to use pipes and operators in RxJS to transform observables in Angular. Learn to chain multiple operators to filter, map, and modify data events before delivering them to observers, enhancing reactive programming skills.
We'll cover the following...
In some cases, we may not want to directly deal with the values from an observable. We may need to filter and transform it before delivering it to the observer. RxJS allows us to transform an observable by using pipes and operators.
Understanding operators
An operator is a technical term for a function. Plain and simple. An operator takes in an observable, transforms it, and spits out a brand new observable. We can use an operator to alter the value.
Using an operator
The current observable will emit the event object. This is because we’re listening for the input event on the <input> element. Let’s say rather than returning the entire ...
