The most sustainable way to make the business successful in today’s competitive & fast-paced digital era is building user-centric websites and applications. An online platform is important for your business to get recognized among users.

To put it short, the online platform provides a seamless experience to the users and it has led businesses to dig deeper and get a new way of reaching the customers online.

That is the main reason why organizations are moving towards building a few parts of their web application with this newly emerged term “Single Page Application (SPA)”.

So, what is a single page application, and why did the need arise for SPAs?

In the past, browsers were less capable in terms of performance in comparison to today’s page. Every time you click something, a new page gets loaded from the server which makes it time-consuming. But, the same is not the case with a single-page app. It will only reload the data which the user has requested thus, the process becomes faster.

So, that’s how the single-page applications came in the picture. If you’ve got a brilliant web app idea, and you’re in search of a perfect technology to build your app, then this blog is for you.

Curious to know more about this one-page web app? Let’s deep dive into it!

What is a Single Page Application?

Best Single Page Application

As the names suggests, it is a single page where all information is available on the same page. It is even known as a type of web application architecture used to manage the components of a web app.

Whenever you click something or scroll the page, only a few elements will change and the rest will remain the same. Single Page Application monitoring works in the browser and does not require any extra page load time. The SPAs only load the information that you ask for with a click. For instance, when you browse through an email, you’ll notice that every information on sidebar or header will remain as it is when you navigate through the inbox or anything such.

In technical terms, single page web applications is a design approach with HTML5 and modern browsers to shift page and UI logic from the server to browser in lesser time. It uses JavaScript, HTML and CSS to load the resources dynamically.

The thing to always remember about the SPAs is the page neither gets reloaded at any point of the process nor transforms the control to another page.

It is a win-win situation. Users don’t need to wait much for the information, and the server has to send lesser data. This approach enhances the overall user experience.

Best Single Page Application Examples

The websites mentioned below are the ones that you use in your day-to-day life. But you might not know that they are built as SPAs.

Best SAP Examples

But the list does not end here, there are tons of SPA examples. So, what do you think? Why did all these huge companies decide to go with the single page application approach?

Benefits of Single Page Applications

Benefits of Single Page Applications

There are immense benefits of SPAs. Let’s get through some of them.

Quick Loading Time

In single page web apps, once the page gets loaded, the server does not send any more HTML or CSS. Whereas for the traditional one, every time when new data is requested, the whole page gets reloaded.

Single Page Application vs. Multi Page Application

Thus, the quick interchangeability makes single page web applications useful to the pages that need to use the same template innumerable times. According to Google Research, if a page takes more than or around 200 milliseconds to load, it has a high impact on the business and sales.

Good Caching Abilities

One of the best advantages of single page application development is that it can cache any local data efficiently. The SPA just sends one request and stores all data from the server. As there is on-going access to the data, users can even work offline. Here, the local data is synchronized with the server.

Improved User Experience

Single page web apps are amazing for creating innovative pages and providing an amazing user experience. As the users do not need to wait for the new page to load. The dynamic loading of the content gives the user a seamless experience.

Rapid Front-End Development

The SPAs let the developers build front-end development faster than before.

The main reason for it is decoupled single page application architecture. It separates the front end and back end development services. With this decoupled setup, developers can build, test and deploy the front-end independently.

Everything works here through APIs, that follow the standard rules on how to structure, exchange and recollect the data. APIs lets developers work independently and quickly.

Drawbacks of Single Page Application Architecture

Along with benefits, there come a few disadvantages too for SPAs.

Search Engine Optimization

It is a common opinion that SPAs do not have a good impression on search engine optimization. The main reason for it is single page web apps run on the javascript. The data here will be downloaded when users send a request. With all this, the URL of the page remains the same as the different pages do not have a unique URL. Further, it becomes hard to optimize for search engines as the search bots can’t scan the pages.

Google Search is now improving to optimize the SPAs page, but the developers need to make sure that the Javascript files built by them are indexed by Google. The reason is Google has its own Crawler.

Complex SPAs Comes with Issue

When you build a complex single page application, it maybe inconvenient to use because of its size. They do not perform well with such complexity. The loading time of the page may increase due to its complexity. It can give a bad experience to the user and may decrease the user engagement.


We know that analytics tools can track the page view, just by adding a single code to the page. But the situation isn’t the same single page web apps. As the SPAs aren’t the real pages. You need to add logic for tracking and need to ensure that the analytical tool will pick a new page without the need of refreshing the page. But, it becomes a bit of a cumbersome task to add new logic to the code.

When To Use Single Page Application?

Single page web apps are an ideal choice when thinking about future web development. This architecture is a perfect choice for social networks stuff, SaaS platforms, or some close communities where SEO doesn’t matter. Though, if your project needs an effective SEO then we would suggest you go for a multi-page application.

On the other hand, if you want excellent and rich communication between your application and users, then the SPA approach is a must. With that, if you need real-time updates on the page, then single page application architecture will suit best.

So, these are some of the situations that require SPAs approach.
