Building Modern Web Apps with Single Page Applications (SPA)

Updated: Feb 13


Single Page Application (SAPs)

Imagine a web application that provides a smooth user experience, reduces load time, streamlines the development process, and consumes fewer server resources.

That’s what you get with a single-page application. Many developers and e-commerce entrepreneurs use it. Tech behemoths like Google also use the same for Google Maps or Gmail to engage the users.

If you’re considering building a web application, SPA could be the cherry on the cake top based on your requirements for a cross-platform compatible, faster, and feature-rich application. You can use it for your social media/e-commerce website or other use cases.

Before delving deeper, let’s briefly look at the introduction of a single-page application.

What are single-page applications?

A single-page application or SPA is a single web page or web application. It works within the web browser that loads an HTML page. It dynamically updates the content once the user interacts with the application. It enables the user to have a fluid and seamless experience, as the page doesn’t need to reload every time the user clicks on a link or interacts with the application. SPAs use the JavaScript framework like React, Vue, or Angular to handle the dynamic updates.

What are some examples of businesses that have successfully implemented SPA?

Trello, Gmail, and Facebook are all examples of single-page applications that offer outstanding experience with no page reloading. For example, Gmail doesn't show any changes during navigation. The sidebar and the header are the same in the inbox, so once you receive a new email, it reflects the changes by loading the content over JavaScript.

How does single page application work?

The architecture of SPA is simple and clean. It includes client-side and server-side rendering technologies.

Suppose you have to visit a web page. Once you enter the address to request access from the browser, it will fetch this request to the server. It comes with the HTML document in return. Once you use the single-page application, the server fetches the HTML document for the first request. For the subsequent ones, it sends JSON data. It means the single SPA will rewrite the entire page's content without reloading the whole web page. Therefore, you can expect a faster performance. It helps SPA to behave like a native application.

Why must you opt for SPA for your business web application?

An array of benefits is there when it comes to choosing single-page applications. It will enhance the customer experience, and the back-end design will be a breeze. Here are some benefits-

  • Single-time file load

The server won’t send any more HTML once the initial page is loaded. A server sends a shell page, and the web browser renders UI or user experience. Moving forward, the subsequent clicks send the back requests for markup and data. Consequently, the servers fetch the raw materials to the browsers. Then, the browser accepts the same and renders an updated UI. It’s quick and seamless, making the SPA useful for pages with repetitive templates.

  • Increased speed

According to HubSpot, one one-second delay in website load times can reduce the conversions by 4.42% for a second. It’s more prevalent in the e-commerce industry and leads to an increased bounce rate. On that note, web applications should offer a faster speed to decrease bounce rates.

SPA offers quicker response times because the entire page does not reload. Also, the data changes as requested on selected content parts, so the web application speed improves significantly.

  • Improved user experience

Seamless user experience is pivotal for a web application's success. Reports claim that users leave web pages due to slow loading speed and difficulty to use. With SPA, users don't need to wait until they reload the entire content but instead gain the information faster, which enhances the overall user experience using SPA.

  • Easier development

SPA development is easier for developers because they don't need to spend as much time writing code and rendering web pages on the server. Instead, developers can reuse the server side while decoupling the SPA from a front-end user interface. This allows the front-end and back-end teams to focus on their respective tasks.

  • Efficient data caching

SPA can cache data effectively because it only sends one request to the server. Then, it updates the other data. This allows SPA to function even when you're not online. It can also synchronize data if a user's connectivity cuts off.
