Custom State Management in Angular: Build It Like a Pro

Have you ever found yourself in a situation where you needed to manage complex data flows across multiple components in an Angular application, but you couldn’t use a State Management library for some reason? Maybe you were restricted by project architecture, or you simply preferred to have more control over your code. Whatever the reason may be, fear not! In this article, we will explore a practical approach to designing a custom State Management system using RxJS and BehaviorSubjects. This solution will allow you to manage complex data flows in an Angular application without relying on a third-party library. Let’s dive in!

Designing the State Management System

The first step in building a custom state management solution is to design the system. Before writing any code, you need to have a clear understanding of how your state will be structured and how it will be accessed and modified.

In this article, we will be using RxJS and its powerful BehaviorSubjects to create our custom state management system. The BehaviorSubject is a type of Observable that has a current value and emits that value to subscribers when it changes. Unlike the Subject, you must assign a value when declaring your BehaviorSubject. Additionally, you can access the current value of a BehaviorSubject…
