Why You Must Choose AngularJS for Single Page Application Development?

September 16, 2020

How often do you experience the annoying wait while navigating through a web app? Looking continuously at the screen and waiting long for a page to load. Frustrating, isn’t it? A Single Page Application (SPA) improves the overall experience for a viewer. This type of application fits itself into a single page to provide a great user experience, similar to that of a desktop application.
Before digging the reasons for choosing Angular JS for developing single page application, let’s understand each segment distinctly.

What are Single Page Applications?

A Single Page Application or SPA is a type of website or web application which that can dynamically reload particular page elements depending on the interactions of the users. It helps in avoiding the loading of new pages from a specific server. This is what helps in enhancing the speed and overall user experience. SPA try to offer the same kind of experience as a desktop application. Some of the most popular single page applications users include WhatsApp Web, Flickr, Gmail etc.

Core Features of Single Page Applications

Let’s take a look at some of the main features of a single page application.

Fast and responsive
Since single-page applications don’t update the entire page but only required content, they significantly improve a website’s speed. Most resources (HTML/CSS/Scripts) are only loaded once throughout the lifespan of an application. Only data is transmitted back and forth. This is a great advantage, and according to Google research, if a page takes more than 200 milliseconds to load it can have a potentially high impact on business and sales.

Caching capabilities
A single-page app can cache any local data effectively. An SPA sends only one request to a server and then stores all the data it receives. Then it can use this data and work even offline. If a user has poor connectivity, local data can be synchronized with the server when the connection allows.

Debugging with Chrome
It’s easy to debug an SPA with Chrome since such apps are developed on frameworks like AngularJS Batarang and React developer tools. These frameworks have their own Chrome developer tools that make debugging much easier than with MPAs. In addition, SPAs allow you to monitor network operations and investigate page elements and data associated with them.

What is AngularJS?

“AngularJS is a structural framework for dynamic web apps. It lets you use HTML as your template language and lets you extend HTML’s syntax to express your application’s components clearly and succinctly. AngularJS’s data binding and dependency injection eliminate much of the code you would otherwise have to write. Moreover, it all happens within the browser, making it an ideal partner with any server technology.”

Although developing a single page application seems easy but coding and other technicalities can be a hassle. To simplify the task, you can hire an Angular JS developer.

Key Features of AngularJS

  • Data Binding: Automatically integrates the data between view elements and the model.
  • Scopes: This works as lubrication between controller and view.
  • Controllers: It is a JavaScript function that links to a specific scope.
  • Services: This feature helps in arranging and sharing code through the application.
  • Templates: It includes attributes and elements that belong to the AngularJS family.
  • Directives: They serve as markers for DOM elements including attributes, CSS, and the like.

Benefits Of Developing a Single Page Web Applications Using AngularJS

Two-Way Binding Feature
AngularJS allows for an immediate synchronization between the view and the model. If any data is altered in the model, it reflects in the view. When changes are made in the view data, the model is revised accordingly.

Using this two-way data binding, the application will significantly simplify its presentation layer. This allows a simpler, less intrusive approach to DOM display to construct the UI.

Supports SPA Features
The main motive for developing single-page applications is a faster website transition. The website will function and appear like a native app. A website will communicate with the web browser by dynamically replacing the existing web page with new Web server data, instead of the browser’s default method of loading completely new pages. This is referred to as a Single Page Application (SPA).

AngularJS supports the development of Single Page Applications. When a programmer develops a Single page application using AngularJS, the page loads quickly, works on every platform, provides excellent user experience, and is much easier to maintain.

Declarative UI
The AngularJS framework creates templates using HTML. It is a declarative language popularly used because of its scalability and innate intuitiveness. Templates include AngularJS specific elements and attributes such as filters, directives such as ng-app, ng-repeat, ng-model, form controls and so on.

Having a declarative user interface helps make things more understandable and easy to manipulate. Using HTML lets developers and designers work together. While developers can use declarative binding syntax to connect the various UI components with data models, the designers can focus on creating UI.

Allows for Optimal Web Application Management
Web developers typically need to break down the code up into three different components: Model, View and Control (MVC). Then, developers manually merge the code of those components. AngularJS saves time as this framework automatically strings the code together.

The model component maintains and manages the application data. The view component displays all data or certain portions of the data to the users. While the control component dictates the relationship between the model and the view.

It is easier for developers to manage the UI part of the application and its database using this MVC pattern.

Powerful Framework
Another AngularJS benefit is a robust solution for faster front-end development. It has multiple features such as MVC pattern, directives, and dependency injection. It is a common platform among developers because it is freely available. This allows developers to expand the HTML syntax and build client-side applications.

Real-Time Testing
Easily test your web app using the AngularJS framework. AngularJS allows for both end-to-end and unit testing. Testing features offered by AngularJS, such as dependency injection, oversee how the components of your web application are generated. Additionally, testing features show how to resolve their dependencies. This makes it easier for developers to test their applications and check for errors.

AngularJS is a great framework for developing high-quality dynamic web applications. This is because AngularJS is feature-rich and developers do not need to depend on any third-party software to support their applications. Developers can save a lot of time and resources while working on their projects with AngularJS.

Summary
AngularJS is a really great option for building SPA applications because of the number of features that make the entire process possible. AngularJS has the capability of handling the development of web applications, right from wireframing to development and testing.
