What is SPA?

Before Angular 2 most of the application was MPA-Multi Page Application means you have to create multiple pages for the website then upload it to run.

But now Using Angular 2 we can build single page application(SPAs) means it has only one index page and all other content will be changed on user request through component without reloading page. So it makes our application very faster.

Where a standard web app or website load the page on every click on navigation and links, the single page application load all the necessary code and modules on initial page load and changes the view and data on user clicks and actions without any page reload.

Even if it required to communicate to the database, it fetches or exchanges the data behind the scene and sync the data using Ajax without reloading the page.

GMAIL is the very popular example of SPA
