AngularJS is an open-source web application framework. It was originally developed in 2009 by Misko Hevery and Adam Abrons. It is now maintained by Google.
AngularJS is a structural framework for dynamic web applications. It lets you use HTML as your template language and lets you extend HTML’s syntax to express your application components clearly and succinctly. Its 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.
Features of AngularJS:
1) HTML User Interface
2) The MVC Framework
3) Behaviour with Directives
4) Access to the POJO Model
5) Unit Testing Facilities
6) Dependency Injection
HTML User Interface
Another great feature of AngularJS is the fact that it uses the HTML language to build user interfaces. The HTML language is a common and declarative language with very short tags that are simple to understand. This leads to a more organized and simplistic UI.
The MVC Framework
AngularJS provides developers with “Model View Control” architecture which is perfect for dynamic modelling. As you may already know, any application is built from a process of combining modules together. These modules work using different logics that are initialized according to individual needs. Developers need to build components separately then combine them together with code.
MVC with AngularJS makes it easier for developers to build client-side web applications. All the necessary elements are developed separately and combined automatically, which saves developers a great deal of additional time and effort.
Behaviour with Directives
Angular provides extra functionality with the HTML language using directives. The additional elements in the system can be accessed with no need for the DOM to simulate additional elements. The controller doesn’t need to manipulate the DOM directly, as this should be done through directives.
Directives make up a separate part of the element set which can be used anywhere other than in a web application. Directives give developers the element-rich HTML they need to strengthen their online presence.
Access to the POJO Model
Unit Testing Facilities
Reliability and performance are an important part of making sure that a site works as it should. Before AngularJS, testing would have to be performed by creating an individual test page and using that page to test the behaviour of each component. This was a frustrating and time-consuming process.
The application simply uses Dependency injection to bind the application together. This helps everything to function as it should while managing the control with a lot of simplicity.
AngularJS has a built-in dependency injection subsystem that helps the developer to create, understand, and test the applications easily.
As you might naturally guess, filters in the AngularJS framework simply filter out the data before it reaches the view. They perform paginations, as well as filtering data arrays with respect to available parameters. The functions can be modified according to the ideal parameters in your system, but these are the only data transformation tasks done.
The system works by putting information into the right format before it’s delivered to the end-user. For instance, it might put a decimal point in a number before reversing the order of numbers in a desired range.
Finally, in AngularJS, it’s possible to use templates to help you build the perfect framework faster. In this network, your template is made of plain HTML, but the language can be extended to include instructions on how the model should be shown in the end view. Templates can be parsed by the browser into the DOM, which then becomes the input for the AngularJS compiler.
These are the rendered view with information from the controller and model. These can be a single file (such as index.html) or multiple views in one page using partials.
Advantages of AngularJS
- 1) It provides the capability to create Single Page Application in a very clean and maintainable way.
- 2) It provides data binding capability to HTML. Thus, it gives user a rich and responsive experience.
- 3) AngularJS code is unit testable.
- 4) AngularJS uses dependency injection and make use of separation of concerns.
