Simplifying Communications Using Subjects in Angular
As an Angular developer, you must have written something like below:
this.data$ = new BehaviorSubject
From an Angular developer's perspective, the above code is beginning to transfer data between two unrelated or hierarchical components.
Usually, to transfer data, different state management techniques are used. However, we can still use simple RxJS Subjects for the same purpose. So mastering RxJS Subject helps you to write a simple service for the same purpose of data transfer and state management.
By definition, a Subject is a multicast observable, which is an observer also. By the end of this live coding-based talk, you will learn,
1. How subject is different from observable
2. What are the different types of subjects
- Subject
- BehaviorSubject
- AsyncSubject
- ReplaySubject
3. When to use which type
The talk will contain no slides, and we will explore all concepts using live coding.
