Implementing Angular CRUD Operations with NGRX Pattern and Material UI Design | Angular NGRX Examples

HTML is the backbone of any website and when used with Angular, it offers a powerful way to create dynamic and interactive web applications. In this article, we will explore the concept of CRUD action using the NGRX pattern in Angular, along with Material UI design examples.

CRUD stands for Create, Read, Update, and Delete, which are the basic operations we perform on data in any application. The NGRX pattern is a state management solution for Angular applications that allows us to manage the application state in a predictable and centralized way. Material UI is a popular design system for creating beautiful and responsive user interfaces.

Let’s start by discussing the basic structure of an Angular application. In Angular, we have components that are responsible for rendering the UI, services that handle the business logic, and templates that define the structure and layout of the UI.

To begin with, we need to set up the NGRX store, which is a central datastore that holds the application state. We can install the necessary packages by running the following command in the terminal:

“`
npm install @ngrx/store
npm install @ngrx/effects
npm install @ngrx/entity
“`

Next, we need to create actions, which are plain objects that describe an event that can occur in the application. For example, we can create actions for creating, reading, updating, and deleting data. We can define these actions using HTML tags, as shown below:

“`html


“`

In the above code, we use the ‘app-action’ tag to define an action of type “CREATE” with a payload containing the name and age of a person. Similarly, we can define actions for other CRUD operations.

Once we have defined the actions, we need to create reducers, which are pure functions that take the current state and an action as input and return a new state based on the action. We can define reducers using HTML tags, like this:

“`html


“`

In the above code, we use the ‘app-reducer’ tag to define a reducer. We pass the current state, the action, and a callback function to handle the state change event. The ‘handleStateChange’ function will be called whenever the state changes, allowing us to update the UI accordingly.

To implement the CRUD actions, we need to create effects, which are functions that listen to specific actions and perform side effects, such as making server requests or updating the database. We can define effects using HTML tags, as shown below:

“`html


“`

In the above code, we use the ‘app-effect’ tag to define an effect that listens to the ‘createAction’ and calls the ‘handleEffect’ function when the effect is triggered.

Finally, we need to render the UI using Material UI design components. Material UI offers a rich set of components that follow the Material Design guidelines and provide a seamless user experience. We can leverage the Material UI components by including the necessary HTML tags, as shown below:

“`html

“`

In the above code, we include the ‘app-material-ui-component’ tag to render a Material UI component.

In conclusion, Angular provides a powerful platform for building web applications, and when combined with HTML tags, the NGRX pattern, and Material UI design, we can create robust and aesthetically appealing applications. By using HTML tags, we can define actions, reducers, and effects, and by leveraging the Material UI components, we can create a beautiful and responsive user interface. So, go ahead and dive into Angular CRUD actions using the NGRX pattern and Material UI design to take your application development skills to the next level!
