Angular.js and its Strengths

December 20, 2019

Angular.js and its Strengths

Angular.js has already found its numerous devotees. This is a framework predominantly aimed at creating one-page applications. Due to the MVC pattern (Model-view-controller), Angular-based applications are more structured, and the testing and development processes are easier.

It will not become time-consuming to study the basics of this framework, that is why a couple of hours may be enough to learn creating small apps. Instead, feature learning might take several months.

 Among the Angular.js strengths, you may find the following ones: 

  • Google and Microsoft support;
  • two-way data binding;
  • an extensive community involving both developers and those willing to become efficient in framework design and upgrading;
  • a nice interaction with other libraries;
  • pattern depiction as HTML-tags, which disposes a server of extra work;
  • declarative programming makes code support and reading easier;
  • an opportunity of development of web-applications that will be downloaded as web-pages simultaneously providing additional functionalities. 

Two-way data binding via Angular.js

Two-way data binding is one of the significant features of this framework. By this, it is meant that changes taking place can be instantly viewed through the application objects. 

Two-way binding is formed with the help of compiler and $compile. Then Angular.js generates DOM-elements that will be used further. $compile transforms HTML-code into the function initiated for content generation. 

Angular Architecture:

  • Module contains the structures where directives, services, and components are united within one logics;
  • Component is a class in conjunction with a pattern responsible for using that logics on a page. A part of this code may be used within a whole application.
  • Template is a part of HTML-code together with syntax;
  • Service is a typescript class aimed at data storage, obtaining and processing.
  • Router is responsible for content depiction while screen changing.
  • Pipe deals with data formatting in HTML-pattern. Among the most frequently used Pipes, there are date (date formatting), number (number formatting), uppercase (changing the case into an upper one), slice (line cutting), decimal (determines the number format);
  • Directives means the alteration of a DOM-component (Document Object Model) appearance or behavior.

Angular.js main directives may be characterized as follows:

  • ng-app – provides the change of behavior using special tags;
  • ng-bind – makes ties to an inner Text HTML-element feature;
  • ng-init – the initialization of application changing parts takes place;
  • ng-model – points at the necessity of two-way data binding;
  • ng-class – estimates the class set to be used within an element;
  • ng-controller – provides attaching of controllers to HTML DOM;
  • ng-repeat -  several samples are created for each collection element;
  • ng-form – FormGroup object is created by a directive; the latter one is responsible for its further attachment to a form;
  • ng-if – adding/deleting of an element;
  • ng-for – takes some array elements in a certain pattern.

A multitude of popular websites have been developed via Angular JS:

1. https://www.upwork.com/ is a popular English-language global platform for job search generated by numerous developers, copywriters, designers and freelancers from the other spheres. Being reliable, easy in use, and accessible, this platform has acquired its target audience:

2. appstoreconnect.apple.com contains a set of instruments that allow to control applications. In particular, iPhone, Mac, iPad applications are conjunct with App Store:

3. web.telegram.org is a convenient and quick communication tool:

Multi-purposefulness and strength of Angular.js in conjunction with canned solutions enables utilizing various interfaces on websites. Mobile and desktop application development is another peculiarity. Moreover, being supported by Google, framework is constantly updated. In addition, multifunctional performance and an opportunity to insert a code directly into HTML make the other great pluses. That is why, you will be able to achieve great results with the assistance of well-qualified developers.
