What are single page application’s benefits?
Single Page Application (SPA) is a website or web application specializing in interacting with users through one page without reloading or popping up another.
They work by rewriting data taken from the web server. SPA contains only one HTML web page while all the necessary resources, like CSS JavaScript codes, are either loaded into the page or retrieved by the browser.
These resources will be used for responding to user actions on the web page. Those resources are reloaded whenever a request is made, while other components remain the same. This is different from standard web browsers, which require a complete reload of the page.
Single page application is an effective client-side application that delivers incredible speed and performance. Most enterprises choose SPAs for their affordable web development costs, high-quality security, portability, and quick debugging and testing.
Why is most SPA built with javascript?
JavaScript is usually built in most SPAs as it can boost the speed of SPA. Also, most JavaScript frameworks are constantly updated with advanced features that efficiently deal with single-page applications’ server-side rendering. Thanks to this feature, your customers can access a well-functioning web page.
JavaScript’s server-side rendering can also make a difference in Search Engine Optimization (SEO). Web pages can load faster, respond better and be more accessible to visitors. This gives tremendous advantages to your ranking.
What’s more, the JavaScript framework can play as a handy toolkit for your company’s single-page app. It is an effective tool for handling complicated interactions on the server side and building interactive user interface for your app.
Top 10 best single page application frameworks to use
If you don’t know where to start, take a look at our recommendation list of 10 best single page application frameworks
1. ReactJS
More than a framework, ReactJS plays as a library of necessary components for User Interface (UI) design in websites and applications. ReactJS can work as a server-side framework thanks to its vast range of applications and features. If required, both the front-end and back-end servers can utilize the ReactJS framework by enabling the distribution from the server.
ReactJS contributes to SPA development with component-based architecture. It includes a virtual DOM for better performance. The virtual DOM allows your development team to keep track of the changes within the system without affecting unchanged elements. Therefore, your application has more flexibility and reusability.
Compared to other single page application frameworks, ReactJS is much more flexible since it works as a stand-alone library, letting it work with good response time. ReactJS is crafted explicitly for testing, debugging, and viewing elements inside the Model-View-Controller (MVC) architecture. This viewing feature allows the developers to update the UI without returning to obtain a new view. Overall, ReactJS is the best JavaScript framework for SPA.
