Angular development using the Angular CLI tool. In order to install Angular CLI, we need to install nodejs first. 

Prerequisites

• Node Js (latest version) - nodejs download
• Angular CLI
• Prior knowledge of Typescript

Step 1: Install Angular CLI 10

Angular CLI is used to initialize, develop, and maintain Angular applications. It uses the command line.

Open Powershell terminal or command prompt and enter the below line to install the Angular CLI,

$ npm install -g @angular/cli

Once the Angular CLI is installed, at the end you can see the  @angular/[email protected] on your terminal.

Now you are good to go to create your first Angular 10 app.

Step 2: Create your first Angular 10 project

We use Angular CLI to create our Angular project. Open Powershell terminal or command prompt,

$ ng new sample-app

When enter the above command the Angular CLI will prompt you and will ask whether you want to add Angular routing or not.  Next, it will ask you which stylesheet format you want tp add. Once you enter proper response then Angular CLI will create the folders and files, install the packages for our project.

Once the angular project/app is created, you will see the below folder structure and files, (i.e., app component Html, scss and typescript files),

Step 3: Run Angular Application

Use below command to compile and run the angular application, Go to your projects root folder (i.e., sample-app) and run the ng serve command

$ cd sample-app 
$ ng serve

The Angular application will be available in this  http://localhost:4200/  URL/address.

If you use ng serve --open , it will automatically open your application in the browser using http://localhost:4200/ address/URL. OR you have to open browser manually enter http://localhost:4200/ address, then you will see the below page,
