Analysis of Key Aspects for building SPAs Using AngularJS

As an IT Software Consultant, I keep looking for new frameworks and tools, recently I have been looking for the best framework to develop single page business applications (SPAs). And, I got this:

There are various platforms available for single page application development, my choice is not always clear. If I go by the stats, then the most used and popular JavaScript libraries, frameworks, and tools among software developers are Node.js, AngularJS, ReactJS, Vue.JS, .NET Core, TensorFlow, Xamarin, and Cordova.

To build and maintain a single page application, I only need a reliable and productive tool. My immediate concern is, which JavaScript framework should I use to make sure that my app development project is the most successful one?

According to market trends and reports, AngularJS is the best platform to create your single page applications. Further, read on to see why Angular JS development is the preferred choice to create a single page web app.

AngularJS is a structured JavaScript framework that’s a perfect fit to build dynamic single page applications for your enterprise. It also supports multiple platforms and all the commands and functions of this framework are written in HTML script.

Google’s AngularJS has around 59,520 ⭐️(Star) on GitHub. It’s the right platform to build web applications with declarative templates and the most useful CLI tool to easily get started on your project.

Key Aspects of Angular JS for Building Single Page Applications

1. MVC Framework and POJO Model

AngularJS has no dependencies on underscore.js and jQuery. It works on Model View Controller (MVC) framework that is a design pattern for developing SPA and web applications.

The MVC Framework

Model is responsible for maintaining data storage, integrity, consistency, queries, and mutations. It is the simplest form of script that works without using any form of sorter and getter methods.

The controller is responsible to receive, validate, interact, and responds to user input within the data model objects. In short, it controls the whole interaction between the model and the view.

The view is responsible for the presentation of assets and codes entered by a user. In Angular MVC the whole pattern is written in HTML and JavaScript. For example, the View is implemented in HTML and the Model and the Controller are implemented in JavaScript.

The View in an AngularJS application created using HTML coding

<!DOCTYPE html>

<html>

<head>

<title>Hack Hands Angular — Demos</title>

<meta charset=”utf-8" />

</head>

<body>

<div id=”messageTitle”></div>

<div id=”message”>Hello World</div>

</body>

</html>

Adding a Controller to the Angular JS application

var indexController = hackApp.controller(“indexController”, function ($scope) {

// controller logic goes here

}

);

Adding information to the model

var indexController = hackApp.controller(“indexController”, function ($scope) {

// controller logic goes here

$scope.message = “Hello Hacking World”

}

);

It’s so easy to build single page application on Angular MVC. So, the recommendation is to use Angular JS, I have done it without writing any extra codes. Angular MVC supports two-way data binding and allows you to view your data based on your own preferences.

When it comes to data binding, AngularJS uses POJO (Plain Old JavaScript) objects that require no additional elements to bind the AngularJS with other data sources. This is also one of the main reasons why I prefer to use AngularJS for SPA (Single Page Application) development project.

2. Routing Between Web Pages

In single page applications, navigation between web pages is the key aspect of the development process. Every time I don’t want to redirect my website users to a new page when they click on a menu or sub-menu. Single page web applications are all about where the content load on the same page with just typing the URL of the website.

With the AngularJS it is very simple to manage the navigation between web pages as compared to those that are built using other javascript frameworks. The components of AngularJS are lightweight, hence it is one of the preferred forms of the JavaScript framework for developing single page web apps.

3. Community Support on Google

When you start working on a development project, you’ll always look for good community support. AngularJS is supported by Google’s community and is available for download on GitHub. It is supported by most of the browsers including IE version 9 and all above.

So, in case of any maintenance issues, there are different Google forums where you can ask your queries and get them solved by the AngularJS developers.

4. Testing on Selenium and Protractor

You can use Protractor or Selenium to perform automated testing on the AngularJS application. These two are the awesome tools for the testing of AngularJS applications. For the testing of web applications, the most preferred choice is Selenium. Even though I use selenium to test apps, but I recommend you to use Protractor to apply new strategies to test your application, such strategies include:

By.textarea
By.repeater
By.model
WebElement.evaluate
waitForAngular
By.binding
WebElement.all

5. An Agile Platform to Build SPAs

A typical AngularJS app development project starts with a vision and collecting useful static information for the intended audience. AngularJS supports agility which means that it can help create a balance between new requests from businesses as and when they start working in the new work environments. AngularJS controllers can be easily implemented in the MVC architecture to complete these requests. Also, there are a different set of modules to use in AngularJS that can be used for application development. If you wish to customize your existing application, you can choose your modules in place of building a new application from scratch.

You can use the function angular.module for creating, registering and retrieving AngularJS modules. All modules in AngularJS must be registered using this mechanism.

To Conclude

No doubt, single page web applications (SPAs) that are built using AngularJS are user-friendly and interactive in nature. One more benefit of AngularJS app development is that it analyzes the web page document object model (DOM) that allows the program to change the structure, style, and content of the page.

As a result, it reduces the need for extra coding elements. You only need to focus on a single code set for your application and less coding also means fewer chances of error. AngularJS support multi-functional features and easy coding which speed up your app development process.
