AngularJS is a complete Java Script based web application framework developed by Google. It is most widely used to develop cross platform mobile applications and simplifies both the development and testing of applications. It provides a framework for client side model–view–controller (MVC) and model–view–viewmodel (MVVM) architectures, along with components commonly used in rich Internet applications.
This framework works by first reading the HTML page that has a few additional attributes and tags. It reads these attributes as directives in order to bind input or output parts of the page to a model that is represented by standard JavaScript variables.
The main benefit of using this framework is that it was developed and maintained by Google as opposed to hobbyists in the open source community.
AngularJS web development is a complete solution by itself. There are no plugins or frameworks necessary to build a data driven application.
REST easy – Where client server applications are concerned; RESTful applications are becoming a standard. With AngualrJS, with one line of Java Script, you can quickly talk to the server and get the data you need in order to interact with your web pages. AngularJS make this even simpler. It turns it inot a Java Script object as models following the MVVM (Model View View-Model) pattern.
The concept is that the Models talk to the ViewModel objects which in turn listen for changes to the Models. These are all then rendered in the Views – which is basically the HTML that expresses your code.
Everything in the MVVM pattern is automatically communicated across the UI whenever anything changes. This functionality completely eliminates the need for wrappers or getters or class declarations. AngularJS handles everything and you can express your data simply as in Java Script primitives like arrays or through custom types.
Today’s HTML if observed closely is a giant series of div tags with very little semantic clarity. You also need to create exhaustive CSS classes to express the intention of each object. With AngularJs you can operate HTML like XML and you get endless possibilities for tags and attributes.
AngularJS requires no additional frameworks or plug-ins including that for testing. It has a unit testing API which guides you through executing a thorough test of your code and your application as a whole.
AngularJs has a number of features that guide it to create an efficient, performance-driven and highly maintainable front end code base. It can do all the heavy lifting and provides clients with rich, fast and high performing applications that are the need of the hour in today’s highly competitive business scenarios. AngularJS is hence becoming the dominant framework preferred by most developers for web development.
