AngularJS – Explained

AngularJS is an open source structural framework that is used to build dynamic web applications. Originally developed in 2009 by Adam Abrons and Misko Havery, this framework is now maintained and governed by Google. As per the official documentation, AngularJS is defined as follows –

AngularJS is a structural framework for dynamic web apps. It lets you use HTML as your template language and lets you extend HTML’s syntax to express your application’s components clearly and succinctly. Angular’s data binding and dependency injection eliminate much of the code you currently have to write. And it all happens within the browser, making it an ideal partner with any server technology.

With AngularJS, developers can maintain web infrastructures with ease, comfortably. AngularJS’s MVC architecture assists developers build web applications that are rich in design and utilities. AngularJS follows basic HTML & offers extension with capabilities to make web application design dynamic and responsive, while automatically synchronizing with models & views with ease. AngularJS follows DOM methodology which focuses principally on enhancing testability & performance. In a jist AngularJS’ features include, enhanced testing features and directives, 2 way data binding, templates, MVC structure, dependency injections and many more.

What makes AngularJS special? Why should one learn AngularJS?

AngularJS as a hybrid JavaScript/HTML framework immensely simplifies development of web based application when compared with other web services in building a complete and comprehensive web based solutions for businesses and organizations. AngularJS allows developers to extend HTML syntax options, so that they can effectively express application components with ease.

Here are some of the primary reasons why AngularJS as a web application framework is making headlines, while becoming the first option of most developers in constructing web applications.

  • Less on Coding – With AngularJS, a developer can breeze through the development without much involvement into coding. With less coding, AngularJS enables clean and error free way to write codes. This is all because with AngularJS.

    • Developers need not spend time on writing their own pipeline
    • Data Model with AngularJS is simple and here is no need for developers to rely on getter or setter functions
    • Parallel development with possible since directives are independent of app code
    • Manual data passing is completely negated since developers can use data binding feature to pass data into the view
    • Filters in AngularJS allows developers to work on the data without having to change the controllers
    • Views can be made more specific using HTML defined for AngularJS
    • With AngularJS ‘s inbuilt dependency injection subsystem feature, coders can develop applications without much hassle.

  • Enables Parallel Development – If you think, JavaScript was more modular, wait until you know about the modularity features that AngularJS has to offer. It’s just takes modularity to another level and completely eliminates dependencies between development teams. This makes building of application faster easier to manager. Conventional JavaScript applications many a times are a merge nightmare when multiple teams are working across modules. On the other hand, AngularJS is easier to breakdown into multiple actionable modules into their own sub-controllers and services, making developers build and test code independently without disturbing each one’s development.

  • Simplified Testing – Testing in AngularJS is easy and hassle free. AngularJS has dependency injection at its core, which makes it easy to test.  Even the documentation on the AngularJS website has testing as a part of every tutorial step, which almost makes it favorite of every developer.

  • Easy Customization – With the use of directives that AngularJS offers, one can create customer HTML tags that can serve as new, custom widgets. Directives also help design and decorate elements with behaviour and manipulate DOM attributes in interesting ways.

  • Easier Data Binding – AngularJS offers one of the coolest feature for developers i.e. Data Binding.  AngularJS’s Data Binding can save coders from writing a considerable amount of boilerplate code. A distinctive web application usually contain up to 80% of its code base, dedicated to traversing, manipulating, and listening to the Document Object Model. Data-binding makes this code disappear, so a developer can focus on the application.
