Creating a Component

Components can be generated with the Angular CLI. While not mandatory, creating a component using the CLI can save a lot of time. It will save us the trouble of having to create the necessary files and configure the component. We can create a component with the ng generate component <name> command. We’ll use this command to create a Post component.

ng generate component post

This will generate the four files necessary for a component. In the src/app directory, there will be a new directory, called post, with four files called post.component.ts, post.component.html, post.component.css, and post.component.spec.ts.
