What is Angular?​

Angular is a development platform for creating advanced web applications in programming languages like TypeScript, JavaScript, Dart. 

Also, this framework can be used anywhere, for example, many games have been created with its help, and moreover, there are virtual reality applications written in Angular. 

Purposes of using Angular 

This development platform is used to facilitate interaction with a web application. Using it for development will allow the developer to reduce the amount of writing, and get the same result.  

What is necessary to install Angular?

To start working in this platform, you will need to have several components installed, namely: 

• Node.JS 
  A platform for working with TypeScript and JavaScript. 
• NVM (Optional) 
  Node Version Manager.JS, can be very useful in work. It is not necessary that it is present, but its presence can simplify your work. 
• NPM 
  A package manager with which you can download the necessary data package for work in one command. Also, its packages are necessary for Angular to work correctly. 
• TypeScript 
  Although there is the possibility of writing JavaScript code, TypeScript is the main one for the framework. Therefore, writing on it is more reasonable. 
• JavaScript (Optional) 
  Since it is possible to write in JavaScript, you can use it. 
• Nginx (Optional) 
  To access the web interface, you will need a web server. 

How does it work? 

The device of this framework looks like this 

1. Forms 
   The structure in which the user enters the data next, they are sent to the server. Angular has form templates, they only need to be adapted to your task. 
2. Modules 
   The component part of the application that is responsible for managing components. 
3. Components 
   Large parts of the application that are self-contained. The application is built from components as from blocks. 
4. Services 
   They have similarities with components, but are more narrowly focused and can be placed at different levels of the application. 
5. Directives 
   There are two types. The first is structural directives. The second directives that change the appearance, behavior of elements.  

Pros and Cons of using 

Positive: 

• Opportunities 
  Angular has a wide range of features and if you are developing a simple application, then you will not need them. But in the case of developing a complex application, these features will be of great service to you. 
• Flexibility of application 
  As I mentioned earlier, this framework allows you to write not only web applications, but also applications for other platforms. 
• Support 
  Angular developers are Google employees, which is why the company supports the framework. It also has a free license, thanks to which other developers are also developing this framework. 

Minuses: 

• Lack of compatibility 
  Unfortunately, Angular has no compatibility with Angular.JS therefore, those who know Angular and inherit Angular code.JS should learn how to work with this framework. 
• Training 
  Learning Angular is quite a difficult task. Learning it from scratch on your own is a very difficult task, and the developer will also need to know TypeScript. 

How to start working in Angular? 

In order to start developing in this framework, it is first recommended to install a console interface. It is downloaded and installed using NPM, it allows you to create new projects, configure them and much more. 

How to install Angular? 

We made a video about installing Angular in Ubuntu. It's on our Youtube channel. 
 

Conclusion 

Angular is a very powerful development tool that allows you to create not only web applications, but also write code that can be adapted to another environment. With it, you can write a simple program or an application for augmented reality. However, studying is a very time—consuming process that will require a lot of time and effort.
