Google’s AngularJS is an open-source JavaScript framework for web application development. AngularJS can generate all the interactive components seen on a webpage. The framework’s primary goal is to aid in the development of single-page apps (SPA) as it emphasizes code quality and testability.

Gmail could be a classic example of SPA, i.e. when you click on a message in your inbox, the browser stays on the same webpage, but JavaScript code hides the inbox and brings the message body on screen. It may be also reasonable to call Google Spreadsheets a single-page document, based on the fact the page doesn’t reload when you click a different sheet within the same document.

Angular is equally popular over other frameworks available like React.js or Vue.js.

AngularJS Use Cases

Developing an app based on Angular JS requires a clear separation of concerns about the front-end and back-end, thus independence is the most important term here. Once accomplished, the front and back end will be able to expand independently and operate in multiple environments.

A back-end solution, for example, may be used in a web, mobile, and desktop interface. A front-end solution can also operate with many back-end technologies. It’s a more lightweight alternative to RPC (Remote Procedure Calls), and Web Services (SOAP, WSDL, and others). It is based on a stateless, client-server, cacheable coprocessor.

• On-demand video streaming apps.
• User Review Apps.
• Travel Apps & Weather Apps: AngularJS allows the developers to develop an interactive display and helps in performing real-time activities with optimized quality.
• Content portals apps: AngularJS offers the functionality of handling a huge amount of data, posts, and user information.
