Hello World Angular 8

Let’s create our first Angular 8 application.

Create an app:

Command:

ng new app_name

Example:

Create an app and name it as “firstapp”.

Command:

ng new firstapp

A folder is thus created.

Open the folder to check subfolders.

The src is the main folder of a project.
Open the src folder to check its subfolders.

The app folder is the root of the app.
Open the app folder to check its subfolders that include some .ts, HTML and CSS files.

Files used in Angular 8 App folder:

Angular 8 App folders and files that are mainly used in a project are:

src folder: It includes the main code files related to an angular application.
app folder: It includes the files that are created for the app components.
app.component.css: It includes the cascading style sheets code for the app component.
app.component.html: It includes the HTML file related to an app component, which is a template file used for the data binding by angular.
app.component.spec.ts: Being a unit testing file related to the app component, it is used along with other unit tests. This file is run by the command ng test from Angular CLI.
app.component.ts: Being the most important typescript file, it contains the view logic behind the component.
app.module.ts: As a typescript file, it contains all the dependencies for the website. To determine the needed modules to be imported, the components to be declared and the main component to be bootstrapped, this file is utilized.
