3 insane (but true) things about single-page applications

single-page application

There are hardly any companies that don’t require a digital presence these days. Whether it’s a website, an app, or both, a strong digital footprint is a must nowadays to be fully competitive. To do so, they need expert developers who can, for example, build a single-page application for users to enjoy and pick it day after day.

Relying on skilled developers who can create a single-page application is becoming increasingly popular and you may be asking why. Well, that is because single-page apps tend to have a number of benefits when compared to multi-page apps. A few paragraphs ahead, we are going to fully explain what those benefits are.

What is AngularJS?

It’s a framework used to create dynamic web applications. It enables the use of HTML both as the template language and for the syntax. This syntax is used to display the different components of an app. 

What is a single-page application (SPA) in AngularJS?

AngularJS is based on binding UI data in a bi-directional way, and also on dependency injections. All of this is done within the browser itself, making it easy to use with any technology. It’s the first choice for writing single-page applications.

Plus, SPA is a web-based application that is preloaded inside the browser. That means that only a part of the HTML page updates whenever the user interacts with the app. Hence, the response is pretty fast.

Difference between multi-page apps (MPA) and SPA

In order to achieve the best possible application, it’s vital to understand what the best architecture is. It is crucial to build something that is user-friendly without forgetting the aesthetics. This combo makes users choose your app from the competition.

Knowing which type of app you need to construct will help to find the best developers. So let’s revisit:

An SPA is an app that enables working within a browser. Due to how it works, single-page apps don’t need to be reloaded every time a user interacts with it.

On the other hand, multi-page apps require rendering every time a user interacts with it and it’s the most classic way to build applications.

Then, the main difference between these two types of application constructions is loading, as SPAs load much faster than MPAs. Also, there are some other differences that are worth taking into consideration:


  • SPAs do this quicker but end up having a slightly lower level of security. 
  • MPAs secure each page down to its core, which means higher security, but a longer loading time. 


  • Single-page apps are much more user-friendly. The fact that they take zero time to load after user interaction makes for a smooth experience.


  • Multi-page applications are the best choice when building a more complex app, full of content and pages.
  • SPAs are used when creating less intricate applications.


  • MPAs are more SEO-friendly. As they are used to create several pages, they can be better targetable, which means more organic traffic from search engines to the pages.

3 facts about SPA you must learn

Sometimes, when you need to create a highly complex application, you may choose to build it using MPA. However, the majority of the most widely used apps are SPA. Examples of this are:

  • WhatsApp Web.
  • Gmail.
  • Twitter.
  • Airbnb.

Among the three amazing things related to single-page apps, we find these:

1. Fast responsive

Referring back to the previously mentioned notions, single-page applications only load a part of a page. Thus, everything is more dynamic and, therefore, the app ends up being much faster in the eyes of the end user. 

This directly affects the user experience positively. A user is more likely to come back to a website or app that loads fast, rather than one where they have to wait for endless seconds every time they want to launch it.

2.No bugs and caching is simpler

There’s nothing worse than a bug impacting the user experience. It’s even worse when fixing them is a complex task that implies malfunctioning of the app for a long time before it’s achieved.

When building a single-page app, this becomes much easier. That is because most of them are built in Chrome, using technologies such as Vue.js, which means that debugging can be done in the browser itself.

Also, when building a single-page app, the data is collected as a unit. This means that it can be cached all together. Therefore, it positively affects the interaction between the user and the app, since it makes it faster.

3. Perfect for collaborative work

It’s quite typical for more than one person to be developing an application. 

SPAs are great for when that happens since it allows the back-end experts to work specifically on the API, while the front-end developers can focus entirely on creating the UI.

Everyone does their part of the work, which ends up being the best end-user-facing approach.
