At present, the field of web application development is quite competitive. Every day there are more tools that are focused on this area. Of those aspects, the front end stands out because it is the entrance door of the application. In fact, for many users, the graphics aspect is the first evaluation criterion that counts when evaluating an application. In the front end of a web application, we find Javascript that adds dynamism to HTML. From Javascript, there are many frameworks but the most popular is perhaps Angular. So, in this post, I will show you how to install AngularCLI, the tool with which you can create projects in Angular.

AngularCLI: a command line interface for Angular

Angular is a Javascript framework for creating the front end side using the MVC pattern. It was created in 2009 by Google and is becoming more and more popular. Thanks to Angular we will be able to speed up the work from the front end using a lot of Javascript functionalities perfectly organized. Its methodology is the SPA, i.e. single page application.

On the other hand, Angular is being widely used in a new stack called MEAN (MongoDB, ExpressJS, Angular and NodeJS) where you can create other types of web applications.

In order to have a tool to manage Angular better, it is that AngularCLI arises. AngularCLI is a command line interface for Angular, with it, we can create an application that already works, right out of the box.

So, if you use Angular or you want to learn about it, you have to install AngularCLI.

:~$ cd example-project
:~$ ng serve

:~$ ng serve --host [host_ip] --port [port]
