What is Angular?

Let’s see the below image to get a better understanding of what Angular is,

The above image describes the below 4 points, it says,

  1. Open Source
  2. Type Script-Based Framework
  3. Developed by Google.
  4. Used for Single Page Application.

Let’s combine all the above points and the Angular definition would be,

“Angular is an open-source, TypeScript framework created by Google for single page application using TypeScript and HTML.”

Angular is written in TypeScript and mainly used for 

  1. Large Enterprise Application
  2. Single Page Application
  3. Progressive Web Application

Now the question is,

What is a Single Page Application? Let’s understand that,

SPA – Single Page Application

First we will discuss the traditional web page life cycle,

In traditional page life cycle,

The client sent a request to the server. Server renders a new HTML page. This triggers a page refresh in the browser.

In Single Page Application, 

  1. Page load successfully the first time. I mean Client sent a request to the server. The server renders a new HTML page. This trigges a page refresh in the browser.
  2. After that, all subsequent requests with the server happen through AJAX call. I mean client requests to server and server will provide only JSON data instead of HTML.
