What is NgRx? How to use NgRx in Angular Application?

Here Store acts as a client-side database and reflects the existing state of the application. Actions are for different application events, such as user interactions and network requests. Actions define the communication between NgRx and the application. Reducers react to the activities and handle the transition between the states. Selectors help the application listen to the state changes and Effects to manage a range of the side effects of the actions. NgRx can be used in the state management of applications. 

What is AngularJS?

Developers use AngularJS to develop the client-side framework of dynamic web applications. It is an open-source framework based on TypeScript and HTML. Dependency injection, data binding, and some of its other properties are used by the developers to reduce the lines of code required in any dynamic application. HTML is the template language here. The developers can extend the HTML's syntax to clarify the application's different components. You can hire angular js developers if you are looking to use NgRx in it who have a thorough knowledge of NgRx too. 

What is the use of NgRx in Angular?

NgRx can be used to manage the state updates in the application architecture and the events related to the user and server. It should be used to maintain the state uniformity to pass down data required by other components uniformly. The data changes are not reflected in the other components at a higher level. You can hire dedicated Angularjs developers to create an architecture where data can be shared and used in creating a shared service.

How to use the NgRx store with Angular?

The process of managing states of user control is known as state management. It aids developers in building complex applications with lots of data without compromising performance. Angular has two widely used libraries- Ngrx and NGXS which helps in state management. Also, they have some attractive features that make the developers' work effortless. For example, NgRx, inspired by Redux, enforces a unidirectional data flow to assist developers in streamlining the application's state in objects.

Let us check how we can implement a simple application to manage blog articles using the NgRx store with Angular.

Step 1: Installing NgRx

You can install NgRx using NPM, Yarn, or Angular CLI as follows:

Step 2: Creating the Store

Following installation, you must add a new directory called "store" to the src/app directory. All of the NgRx store's files will be located in this folder. The store directory's folder structure would look like the following:

It will help if you start by building an interface for articles. For example, give the model article a name. model.ts.

Step 4: Using the NgRx store

Now, you can start using it in your component. Let us now use AppComponent to display and add articles to the Store.

The app.component.ts file for our example can be seen in the code above. In order to receive the articles, we subscribed to the Store and set articles$ to be a type of observable. Sending new items to the Store is handled by the addArticle() function. Now that we want to display and produce articles, we must alter the app.component.html file.

 

 

And now we are ready to go. We have now configured an NgRx store to an Angular application. For more clarity, you can hire dedicated angular js developers who can serve you the best by understanding your requirements. NgRx is one of the most used libraries for state management in Angular. Above discussed example can give you clarity about using NgRx with Angular. You can simply contact Angularjs development company that has extensive experience in Angularjs development Services.
