Angular has been used by thousands of websites with some of the brand names such as Intel, NBC, ABC News utilizing this framework. Angular JS has gained a lot of popularity in a relatively short span of time in the market and many enterprises have also started adopting this technology for their enterprise application development needs. As a result, most developers can’t imagine creating an impressive single page app (SPA) without using Angular JS.
Let’s examine in detail how this technology can be useful and understand the reasons behind its wide usage across the industry.
What is Angular JS?
Key Advantages of Using Angular JS for Web Application Development
Faster Page Loading
One of the most prominent reasons behind the massive popularity of Angular JS is the faster page loading. Angular JS uses HTML template files which get cached by the browser and prevent server trips in subsequent visits, aiding faster page loads. Similarly, the controller JS files get cached too and the application just needs to fetch new data from the server. Angular JS also allows developers to architect their front-end applications with a minimal coupling on the back-end thereby further improving the page load times.
Application development is very quick and efficient using Angular JS as developers do not need to reinvent the wheel. Most common tasks have high-level wrappers built around them to ease the coding. The data binding and Dependency Injection features of Angular JS eliminate the need to write lengthy code and allow the developers to focus on building the business logic. A cohesive agreement between the model and view can be maintained through minimal code using the two-way data binding. ng-annotate, Bower, JsLint are some popular tools which further help developers in faster development with Angular JS.
Good Programming Practices
Angular JS encourages superior programming practices within the framework and helps in creating high-quality web-applications. By following Angular JS coding guidelines, developers can enjoy many benefits including – model as a source of truth, REST API connection to servers, dependency injection, and the ability to make directives.
Testability of Applications
Angular JS is created keeping testability in mind and is unit testing ready. Through the use of Dependency Injection or DI, Angular JS boosts the testability of the applications. Angular JS applications are linked together using Dependency Injection, which manages the controllers and scopes of the application. Unit tests can simply inject data into the controller and measure the behavior and output. Angular JS, thus, speeds up the overall testing process.
Solid backing by Google
Custom Directives is one of the most powerful features of Angular JS. Custom Directives allow the developers to define the application specifications a lot more clearly than regular HTML elements. A Directive in Angular JS is a reusable component which captures all the functionalities and properties of an element and helps in keeping all of the relevant functionality together. With this, the developers need to keep a track of changes of one HTML section only in one place and they don’t need to worry about debugging the global script in case of any error.
Parallel Development / Collaboration
Angular JS offers flexibility to the developers for writing and testing code side by side, which is especially useful for large projects that rely on multiple key functions. This aids the process of application development which becomes faster and makes it easy for developers.
Angular JS provides a solid framework which is ideal for developing single page applications and helps in speeding up the development process. Besides, some of its distinguishing features including two-way data binding, deep linking power along with custom directives provide the most incredible and robust platform for developers to build fast, rich and high-quality enterprise grade single page applications.
