Parallel HTTP calls from Angular

Tweet

Angular being an extensible framework is widely used for developing high responsive front end modern web applications.

These modern web applications consist of several complex workflows on the server side. To provide access of these workflows to client applications, we need REST APIs so that client applications can access these APIs over HTTP.

Client applications developed using  Front-End frameworks like Angular can make use of HttpClient object from @angular/common/http to access these REST APIs and then using Observable object from RxJs Angular, can store and manage data received from the REST APIs in the front-end application.

But what if the Angular application wants to makes call to REST APIs in Parallel? 

Angular 6 Internationalization (with examples)

Tweet

Angular is one of the most widely used front-end framework for modern web applications. The component-based design of Angular is suitable for modern web applications because each component can have its own UI, DataBinding, Events, etc.

We can use Angular with its object model to design and develop a web application's front-end. Since there could be several users requesting the web application from different parts of the globe, it is important for us to manage the rendering of the UI in a localized format.

Angular 6 Internationalization (i18n)

Angular framework has provided an Internationalization (i18n) tool. This tool helps developers to make application available in multiple languages.

The demo project discussed for this article is implemented using Angular-CLI. If you are new to Angular-CLI then please visit this link. Visual Studio Code, a free IDE tool, is used for this application. It can be downloaded from this link.
