What is the state in Angular?

Inspired by Redux, NgRx provides a way to maintain data in your Angular application as a single source of truth . NgRx uses streams to interact with a data store. This data store connects to your components and services, and ultimately simplifies the entire process of data management in your Angular application.

Never use NgRx if your application is a small one with just a couple of domains or if you want to deliver something quickly . It comes with a lot of boilerplate code, so in some scenarios it will make your coding more difficult.

x) introduced hooks, and in that way motivated the developers to switch from writing class components to currently more popular functional components. That is why we had decided to integrate RxJS as our main state management system .

NgRx uses the Redux concept of unidirectional data flow , where all application data goes through the same lifecycle. This unidirectional data flow makes the application’s state more predictable and thus easier to understand.23 Kas 2021

If you want to make quick decisions in the project you need to know the data well. If you want to make an efficient app you need to design data well. Data is scattered everywhere without state management . State management libraries facilitate one-way data flow in the applications.

NGXS is built on the CQRS pattern (Command and Query Responsibility Segregation), which is also used in libraries such as Redux and NGRX, but it reduces the boilerplate code by using modern TypeScript functions such as decorators and classes.

What is state? State is basically everything that will define the UI that our user will be using . State could be whether a button should be visible or not, it could be the result of that button click and it could also be an Array of users that is coming from an API.
