Angular 15 CRUD Application Tutorial

Angular is a popular JavaScript framework for building web applications. In this tutorial, we will learn how to create a CRUD (Create, Read, Update, Delete) application using Angular 15. We will start from scratch and build a complete Angular project with CRUD operations.

Prerequisites

• Basic knowledge of HTML, CSS, and JavaScript
• Node.js and npm installed on your machine
• Angular CLI installed globally

Step 1: Setup Angular Project

Open your terminal and run the following command to create a new Angular project:


ng new angular-crud-app


This will create a new Angular project folder with all the necessary files and dependencies.

Step 2: Create Components

For our CRUD application, we will need several components such as List, Add, Edit, and View. We can create these components using the Angular CLI command:


ng generate component list
ng generate component add
ng generate component edit
ng generate component view


This will generate the necessary component files and add them to the project.

Step 3: Implement CRUD Operations

Now, we can start implementing the CRUD operations in our Angular application. We will use Angular services to handle the data and communicate with the backend server. We can create a new service using the CLI command:


ng generate service api


Then, we can define methods in the service for creating, reading, updating, and deleting data.

Step 4: Set Up Routing

Next, we need to set up routing for our application to navigate between different components. We can define the routes in the app-routing.module.ts file and specify the components for each route.

Step 5: Create UI for CRUD Operations

Finally, we can create the user interface for our CRUD application. We will use Angular templates and components to display the data and provide forms for adding and editing records.

Conclusion

In this tutorial, we have learned how to create a CRUD application using Angular 15. We started from scratch by setting up a new Angular project, creating components, implementing CRUD operations, setting up routing, and creating the user interface. By following this tutorial, you can build your own CRUD application with Angular and expand it further with additional features and functionalities.
