Let's start

Angular CLI:

CLI acronym for Command Line Interface, and it command line tool which help us to create an angular
application very easy and simple way. It makes our work very easier. It perform many tasks likewise create components,
directives, pipes, services,classes, interfaces, enums etc. Not ony create these things even install and update every in angular.

It is done our task very quickly.

Why we use it:

If you have worked or collect knowledge of Angular, then you already familiar with angular manual setting of an application. And If you have
start your project from scratch the you know well about their hardwork and consume time.

Here just I want to remember your hardwork and time consumption. They are as given below.

1. Create a folder for specific application and add many configuration files.
2. Install each and every packges which is required for your application using NPM.
3. Create a component for an application which is root component and every application should have atleast one component.
4. Create AppModule as every angular application. And every application should have atleast one module.
5. Many more things...


As you can see above or you remembered your past. if we want to create application in angualr then you have
use our extra effort and spend more time. For create a root component you have to create atleast three files manually like
html,css and ts. First create your html file which is app.component.html and second file app.component.css and last one is that app.component.ts
file.

I mean it was not draw back becuase that time it was good. For the time being it have changed.

Then, to overcome our effort Angular CLI comes on picture. Let's try to understand how it overcome our problem quickly not Zero(0) but veryless.
Now a day we do not need to extra effort we have to remember commands and then
perform our task which I want. And it is done by Angular CLI.

Let's real world example:


1. For the installation of angular it play vert vital role.
2. Create any angular application just type command and it takes few seconds.
3. Create components, directives, pipes, services,classes etc. by using commands
