5 Best Single Page Application Frameworks To Consider For Web Apps

What makes users click on your site? What can make your web application stand out?  

If you want your web application to flourish, you need a web application that provides seamless navigation, simple and quick loading, and state-of-the-art features. For developing user-driven applications, most entrepreneurs are looking towards Single Page Applications.  

Single Page Applications are the perfect solution for developing cross-platform, consumer-centric web applications. There are many web frameworks for simplifying and quickening the SPA development process.

We have curated a list of the 5 popular single page application frameworks that you can use in 2021. But first, let’s understand how single page applications work and how web frameworks can assist us.

A Brief Glance at SPAs

As the name suggests, Single Page Application is a web application that has only one web page. It is a client-side application that works with the speed and performance results of a server-side rendered app. 

Single page applications are preferred by enterprises not only for speed, but also for their low costs, high security, fast debugging and testing and portability. Let’s look at how they function before discussing different frameworks that can be used for developing SPAs.

How Do SPAs Work?

When a web browser sends a request for a web page to the server, the SPA sends back an HTML file that contains placeholder elements, along with some files including JavaScript and CSS codes. There is no data or content inside the elements or the HTML file. 

When the browser executes the JavaScript files, the server is requested for content. This content is uploaded to the web browser’s HTML code. These JavaScript files are the soul of single page applications. They dynamically update the DOM in the web browser eliminating the need for refreshing or reloading the web pages.

What Is SPA Framework?

When is SPA the Right Choice For You?

Although there are many advantages of using a single page application architecture, it also has some drawbacks that can lead to eventual pitfalls. 

Therefore, it is important to analyze if your project actually requires a single page application or if a multi-page  web application would be more suited. 

There are countless examples, such as Twitter, Lifehacker, and Delicious when using a single-page application that has backfired and led to a complete redesign into a multiple-page application.  

We suggest going for a SPA only if you meet one of the following requirements-  

  • You have rich, complex UI requirements and want to develop a unique and creative user interface for your web app 
  • Your developer is familiar working with Javascript/Typescript as most SPAs require JavaScript coding 
  • Support browsers without scripting 
  • Minimal client-side application behaviour
  • Small data volume and dynamic platforms, as a lot of content will be tough to transfer over the network and won’t fit into a single web page
  • Search engine optimization doesn’t matter. SAAS platforms and social media networks do not require optimizing for web crawlers 
  • Mobile app development is a part of your plan, as SPAs are extremely mobile-friendly and if you use ReactJS, you can easily convert your single-page app into a mobile application using React Native.  
  • Enterprise applications that do not have multiple websites and datasets

Factors To Consider When Choosing SPA Framework

Now that you have decided to use a single page application, next is choosing the right technology stack. 

Your choice of technology should not be focused on popular trends or competitors while compromising on your business needs. 

It is recommended to understand the project requirements clearly before selecting a SPA framework.  Some questions to keep in mind while choosing a single page application framework for your project are –

  1. Are you expecting to manage the needs of thousands or millions of users? 
  2. Does your project require flexibility such as adding a new feature after it has been published? 
  3. Will the app be large-scale like Gmail or something with a smaller user base such as Trello?   
  4. Does your website/web app require live content updates? Such as a live Covid cases update or football commentary?
  5. Will a slower initial loading time be comfortable? Prefer AngularJS for enhanced performance and lowering load time. 
  6. How many security measures are required?  
  7. How much JavaScript are you going to use in your application? Single page applications require JavaScript enabled in user devices. Will that be a problem later on? 
  8. Does your project require SEO optimization? 
  9. Do you require a one-stop solution including testing, server configurations? Prefer EmberJS for its robustness and batteries included approach.
  10. Do you require a simple focused solution- just UI design or client-side rendering? Prefer Vue or BackboneJS for a lightweight solution
  11. Is scalability something that you require? SPAs are not very scalable. Different frameworks offer various levels of scalability. We suggest React for the highest scalability.

Frequently Asked Questions

We have answered some common queries about single-page applications. For more information, you can contact Monocubed.

What is a SPA?

A single page application is a web application or a website that dynamically updates content on a web page without reloading the whole website. When you interact with a SPA, by scrolling or clicking on an image, only a few elements are updated. For example, when you scroll through Netflix, the dashboard remains in place and only new titles are refreshed.

What are some web frameworks used for SPA?

Web frameworks are essential when developing web applications. Frameworks such as Ember, React, AngularJS provides a simple and efficient platform for developing single-page applications. They feature data binding, DOM manipulations, caching, and application testing that lets developers create a rich user experience. Some other single-page app frameworks include Backbone, Vue, KnockoutJS, and Meteor.

Is Twitter a SPA?

Yes. The famous social networking site is a single-page web application. In 2010, twitter developed a new single-page application architecture written in JavaScript. All the application logic and UI rendering are shifted to client-side JavaScript. Twitter continuously updates the tweet feed with new tweets and posts while the dashboard, the menu, and other UI elements remain constant. When you click an image or a video, only that particular element is refreshed.

When to use Single Page Applications?

Single page applications are an ideal choice for developers when you require fast navigation, rich user experience, inexpensive DOM manipulation, efficient network transfer of data through Ajax, and using processing power on the client browser. Except for a slow initial loading time, SPAs are extremely fast and can incorporate a dynamic user interface where data changes occur automatically on the client side.


Single Page Applications are the reason for rapid loading time and creative user interactions of many popular websites. Developing SPA is an efficient solution for attracting end users and customers.
