Components can be defined as main building blocks of angular applications. An angular application is usually composed of several components.

A Typical Component Structure binds data and logic to its template. angular application can be viewed as an Application tree with the app component being the tree root. The component classes are decorated with the annotations. @component
Previously we had created a Hello World App. We will create the components for this project. We will be creating a component named as employee-list and nest it in parent child style to compose an application. Here employee list will be the child component and the application parent component usually called app component will be the parent.
Navigate to the src/app directory and create a folder named as components and create the component as employee-list.
mkdir components
cd components
ng g component employee-list


We can see that a subdirectory named as employee-list gets created with it containing the corresponding required files.
Next we get the components integrated in the module. For this open the app.component.html and create a div having the tag value as the selector property present in the employee-list.component. In our case the selector value is app-employee-list.

Also in the employee-list.component.html add the data we want this div to display Start the application.
npm start

Now go to localhost:4200-
