Angular

Taking web applications to the new level, we’ll push ourselves into a very powerful front-end framework that is AngularJS. Google introduced Angular 7 years ago and since then it has been used in more than a million projects. It’s also a part of the MEAN stack framework.

Working and its Pros

It mainly works by adding some additional attributes to the HTML elements. The Angular interpreter then reads these elements. One main advantage of this is that it separates application logic from DOM manipulation so the more complex the code structure is, the more difficult is to understand it. Another advantage angular brings is that it brings controllers dependency to the client-side development. Therefore, it reduces most of the server-side burden.

Hands-on

<input type=”text” ng-model =”favSport” />

<p>My Favorite Sports Is: {{ favSport }}</p>

Angula and Bootstrap

Just like the above example, angular makes use of user-specified, reusable and custom directives which work in three phases. It first fires a new injector, compiles the directives which user has created, starts changing the DOM and then links all the directives to the scope.

Some of the most widely used directives for bootstrapping AngularJS are:

Ng-animate: Provides support for CSS3 animations and transitions.

Ng-aria: provides support for common aria attributes.

Ng-controller: used for evaluating HTML expressions.

Versions

Angular 1 and 2 are both called simply Angular. Angular is written in Type-Script based framework. The developers skipped the version 3 to avoid confusion with the v3.3.0 distribution so they released Angular 4 in 2016 and Angular 5 recently in November 2017 with some key improvements. Angular Dart is a version that works on Dart, which uses C# syntax.

Firebase Integration

Angular Fire binding can easily access Firebase database. Firebase provides back-end services and real-time database services. You can also easily synchronize and store data using just a simple API. Firebase also provides support to easily integrate database into other platforms like Android, iOS etc. This database is mainly accessed using the REST APIs which uses the Server-Sent protocols, API for creating HTTP connections therefore developers trust this database as they think the data is secure and they can easily store or access it from the cloud.

Chrome Extension

Batarang is a Google Chrome extension for Angular developed for the purpose of improving debugging experience. Using it, you can easily detect issues and bugs with a good GUI for debugging.
