Creating a Component using Angular CLI

Introduction

Angular CLI is a command line interface for the Angular framework and is the recommended way to create components. Components are the fundamental building blocks of an Angular application, and this guide will explain how to use the Angular CLI to create components and use them in an application.

Steps for creating a Component

Step 1: Install the Angular CLI

The first step is to install the Angular CLI if you haven’t already. To do this, open up a terminal window and run the following command:

npm install -g @angular/cli

Step 2: Create a New Project

Now that the CLI is installed, the next step is to create a new project. To do this, run the following command in the terminal window:

ng new my-project

This will create a new project in a folder called “my-project”.

Step 3: Create a Component

Now that the project is created, the next step is to create a component. To do this, run the following command in the terminal window:

ng generate component my-component

This will create a new component in a folder called “my-component”.

Step 4: Import the Component

The next step is to import the component into the application. To do this, open the `app.module.ts` file and add the following line at the top:

import { MyComponentComponent } from './my-component/my-component.component'

Then add the component to the `declarations` array in the `@NgModule` decorator:

@NgModule({
  declarations: [
    MyComponentComponent
  ]
})

Step 5: Use the Component

Now that the component is imported, the last step is to use it in the application. To do this, open the `app.component.html` file and add the following line:

This will add the component to the application.

Conclusion

This guide has shown how to create a component using the Angular CLI and use it in an application. By following the steps outlined above, you can quickly create components and add them to your application.
