A terrific moment to be a cloud computing company right now! According to Statista, the market is predicted to grow to $101.3 billion by 2022. There is no better time than now to begin thinking about developing an app. Prior to investing your time and resources in architecture, you must first decide which one to use.

On the other hand, developing a cloud-based application is not a straightforward task. You could incur a financial loss if you adopt the incorrect architecture for your application.

Single-page applications and multi-page applications are the two most often used designs nowadays. When comparing the two, this article may help you make an informed choice.

In this post, we examine the pros and cons of SPA and MPA, as well as their strengths and weaknesses. Determine what works best for you

Single Page Application (SPA)

A single-page application (SPA) is a web application that does not require the user to reload the page when it is being used, making it suitable for users who like to work in their browser. A vast majority of the apps that we use daily are single-page applications (one-page apps). Navigation apps, social networking networks, and even email services are all examples of SPAs.

When used in place of a browser, SPAs offer a visually appealing user interface. This is accomplished by ensuring that the amount of code on a page is maintained to a bare minimum. The use of this code guarantees that the SPA will run at peak performance even when JavaScript frameworks are being used.

Multi Pages Applications (MPA)

In MPAs, the browser asks the server to render each new page as it is loaded. The volume of material necessitates different levels of UI, making them ideal for larger applications. When it comes to app creation, they are typically referred to as “conventional,” but this is no longer the case thanks to the introduction of AJAX.

Although AJAX enables the transport of a vast amount of complicated data between the servers and browsers, it also has significant drawbacks. JavaScript’s ability to transport data adds a new level of complexity for developers to contend with.

What is the main difference between a single-page application and a multi-page application?

Let’s take a quick look at the differences between the SPA and the MPA before we get into the specifics.

Newer app development methods use one-page applications. In addition to Google, Facebook, Twitter, and so on, it was also used by other companies. A SPA is a web program that does not necessitate a reload of the page each time it is used.

A more traditional method of app development is the use of numerous pages in a single app. When the content on a page changes, the multi-page design pattern necessitates a page reload. E-commerce enterprises, for example, that have a wide range of products to sell, prefer it.

Multi-page applications were the norm in online applications and websites in the past, but they are no longer the norm today (MPA). There are numerous pages and multiple HTML files in this model, as the name implies. When a user requests a new page, the backend generates the HTML and downloads it from the server, requiring a new page request every time. As data communication does not always occur smoothly, this creates delays in loading and presenting the content. A result of this is that the system’s response time is sometimes excessively long by today’s standards.

It is easier, faster, and more user-friendly to use a SPA than it is to use an SSO. When using a one-page application, there is no need to download additional HTML files. To begin loading its material, it must establish connectivity with the server first. Thus, data and content can be generated directly on the frontend, without any further “delivery” from the backend. A subpage is shown quickly without having to wait for the server to respond to a click.

A single-page application has a better user experience than a multi-page application because of this mechanism. In SPAs, there are no “stitches” between screens or application statuses that are visible to the user. There are many similarities between single-page apps and computer applications that can function offline, such as a computer application that doesn’t run slowly and responds quickly to user requests.

The advantages of SPAs

It is easy to convert SPAs to progressive web applications (PWAs) because of their HTML shells, which provide a more seamless experience for the end-user. Because of their JavaScript-based shell, they can also load preloaded pages when offline. A feature called offline caching ensures that users never lose their data while using the program. Once you send one request, the SPA saves all of the data, and then you can easily access all of this data while you’re disconnected.

Google Play or Apple’s App Store are examples of app stores that allow users to download and install native apps. SPAs have the advantage of being JavaScript-based. Native apps are easier to develop and maintain because JavaScript is the foundation of most of them. It is because of this that technologies like React Native can easily transform your cloud-based web application into a native app.

Beauty in SPAs lies in the ease with which they may be used. The front end of many SPAs is separate from the back end. Front-end HTML and JavaScript capabilities are used by SPAs, and a different framework serves as the functional back-end for these applications. Consequently, if one fails, there is little effect on performance.

The Advantages of MPA

MPAs are good contenders for search engine optimization because of their nature. Most of the time, indexing bots select the majority of the content that the user sees. To top it all off, they may be used with a wide range of different technologies because they are available in multiple frameworks.

Which one to choose between SPA and MPA?

It’s critical to grasp the benefits and drawbacks of both strategies.

  • User Experience: User experience is now a must, not an option. SPAs are more mobile-friendly, which is important to keep in mind as a large portion of traffic originates from smartphones and tablets. Even Google has begun to place more importance on the mobile user experience than the desktop user experience. In SPA development, frameworks are used to create mobile apps.

Information architecture can be improved with MPA’s. There are no boundaries on the number of pages you may build or the amount of content you can add on each page. The user’s experience is enhanced because the website’s navigation is easy to follow.

  • Development Process: The reusable backend code is one of the main advantages of SPAs. The more reusable code you have, the less work it will take to implement. If you have a web app, you can utilise the same code to build a native mobile app. Considering that most of us are constantly on the go, this is a crucial piece of information to keep in mind when developing mobile apps and websites.

The front-end and back-end can be created at the same time, resulting in a faster development process overall. In most circumstances, the server-side of MPAs must be coded from the ground up.

  • Search Engine Optimization: SEO is one of the SPA’s weaknesses. MPA’s, on the other hand, are far more search engine friendly. It’s mostly because JavaScript, which most search engines don’t support, is used in most single-page applications. Crawling and “spidering” are two ways to index web pages. Static HTML pages are easier to rank since search engine crawlers download the HTML files.

MPA enables better website positioning, as each page can be optimized for a different keyword. Also, meta tags can be included on every page – this positively impacts Google rankings.

  • Speed: People’s attention spans are getting shorter and we’re becoming more and more impatient, therefore speed is critical here. They load quicker. Why? Most app resources are loaded only once. When a user requests a new piece of data, the website does not reload completely.

This means that every time the user wants to access fresh data or move around on a website, the browser must reload the entire page from the start. 0.4 seconds is the ideal loading time for a website. If you have a lot of images on your website or app, an SPA is a better choice.

  • Security: Multi-page applications are an example of a website that requires extra work to safeguard – this isn’t a surprise. If you decide to become an MPA, you’ll need to protect every page of your website. Securing data endpoints faster, but not necessarily safer, is all you have to do with an SPA to keep your page secure. Because JavaScript, which powers SPAs, does not undergo code compilation, they are more vulnerable to malware assaults.
  • JavaScript Dependency: JavaScript is a big part of the SPA’s DNA, which can be an issue. Google and other search engines have begun to support JavaScript, but the results have been mixed at best. JS frameworks have a major impact on the level of support. If JavaScript is blocked in a browser, the app’s functionality may be impaired, resulting in a higher bounce rate and a lower rate of conversion. Additionally, its dependency on JavaScript leads to SEO flaws and security concerns. JavaScript is not required to build MPAs.

Thoughts at the end

Even while all the designs outlined above have their advantages and disadvantages, none of them are perfected. Mobile app development can benefit greatly from the speed and code-reusability of SPA, but it is lacking in SEO optimization. There are advantages and disadvantages of using an MPA compared to using a SPA.

As you weigh the pros and cons of each option, remember to keep your business goals and requirements in mind. Social networking applications, SaaS platforms, and other places where SEO rankings aren’t a deal-breaker can benefit from using service-oriented architecture (SPA).
