In this article, I’m going to evaluate this subject. I’ll list the advantages and drawbacks of the SPA approach as well as suggestions on when to use it.
Single-page applications (SPAs) are becoming more and more popular. Facebook, YouTube, Twitter, GitHub, and numerous Google services are all built using the SPA technology.
This will enable users to use websites without loading the whole new pages from the server can end in better results in performance and provide a more dynamic experience. It has some drawbacks like SEO, so it needs more effort to stay still, implement navigation, and do meaningful performance monitoring.
Those who have dealt with web development know that SPA vs MPA comparison is one of the most discussed subjects at the moment. Why is there so much hype about it? And what about the traditional multiple pages? Are they better or they are becoming out of date? These questions have made an interesting idea to talk about. The single-page applications VS multi-page-web applications (MPA). This has to be done in order to help businesses make an informed choice that is suitable for a project.
So when we should go on with a single page or multiple pages?
Let’s find the answer together.
What is a single-page Application?
Single page application is a type of web application that uses a single HTML page as a cover for other pages of the website. In single-page applications, there is only one HTML page and this one page will download various assets during the interaction with the user, they display content without the need to be fully updated because different pieces of the content have been downloaded automatically for each request.
And also it’s good to use SPA when your application must provide an interface with many features and must provide an API for internal clients.
Many web applications are primarily
SPA vs MPA. What’s the difference?
When MPAs react to your input or must display some new content, it requests a new HTML page from the server. After receiving the markup, the browser renders the page and makes it reload the page.
When you work with a SPA, your browser makes an AJAX call to the server, but here instead of rendering a new page, the server is able to send the data to you. The SPA will use those data to render some parts of the pager directly in your browser.
Advantages of SPAs
1. Fast and smooth UX
2. Local caching and offline functionality
After the initial loading the SPAs cache all the necessary data that they receive from a server and store it in local space, this will enable SPAs to function even when the internet connection fails. And when it reconnects to the internet, it will update all the data.
3. Mobile friendly
In the age of technology and the internet users run away from the apps that are slow, so it is not a surprise that mobile users become interested in the apps that load faster in their mobile browsers. Also, SPAs are obviously easier to launch from web to mobile. The same backend code can be used for the web and different platforms of smartphones such as Android or IOS which is something new in comparison to the multi-pages applications. And another thing is that with SPA you don’t need to change the design that much to fit the mobile.
4. Separated back end and front end
In SPAs the UI is separated from the back end. This will enable you to change the front-end as much as you desire without changing or affecting the backend. The fact that UI has separated from the backend helps to find the bugs easier in the codes also integrating new APIs is easier in this approach. All of these actions without affecting the UI.
5. Easy debugging
It’s much easier to debug single-page applications with chrome. All of the codes can be seen at once, and all of the page elements can be inspected together with associated data.
Disadvantages of SPAs
1. SEO problem
2. Memory leaks
The one-page app is essentially a single page that never reloads, it can cause memory loss on other devices and the memory leaks get worse the longer SPA runs.
3. Security issues
Comparing the single-page application with the multi-page application, the SPA is more vulnerable to attacks. In this method, hackers can insert their own client site script into the web apps. But it can be protected with some security layers and data endpoints.
4. Slow loading on the first attempt
SPA launch slower than the usual applications. This happens because of the client-side rendering. Before your browser can render the page, it has to load JS frameworks. This could take some time, especially for a large application.
