For web developers, the “Ajax” term is quite a common tech jargon over the past few years due to its increasing application in practice.
Though the use of Ajax technology for web applications is simple, it shows excellent development potential. For a deeper understanding, let’s discuss the advantages and disadvantages of Ajax. Plus, find out some practices of Ajax technology in Magento 2.
Without further ado, let’s dive in!
It won’t take much time for us to have a quick look at the definition of Ajax. At the most basic level, the acronym of Ajax is Asynchronous JavaScrip and XML.
You can understand it as a set of web development techniques that are used to create better and faster web applications via the use of XML, HTML, CSS, Javascript.
In other words, web applications apply Ajax technology to send and retrieve data from a server without interrupting the display of the existing page.
One of the most outstanding features of AJAX is the ability to retrieve data from the server without the need to refresh the page. Thanks to it, the request traffic on your servers will be reduced significantly, speeding up loading time and improving user experience. And you know what the best part is? It’s the user experience is not interrupted at all.
AJAX lets web pages update content without reloading the whole page, creating a faster and smoother experience, much like using a desktop app.
By sending only the necessary data to the server, AJAX minimizes bandwidth usage, making it easier and quicker to fetch required information and enhancing website loading speeds.
AJAX fetches and updates only the needed data asynchronously, reducing the amount of data exchanged between client and server. This results in lower server load and more efficient resource utilization, even for applications handling large datasets or frequent updates.
AJAX also allows asynchronous data fetching, ensuring that users can interact with the application seamlessly while information is being processed in the background.
With AJAX, you can update specific sections of a web page dynamically without reloading the entire page. This enables quick, uninterrupted interactions, such as submitting forms or loading new data, delivering a desktop-like, responsive experience that feels intuitive and gratifying.
AJAX relies heavily on JavaScript for server communication. If a user disables JavaScript in their browser, they won’t experience AJAX features like faster load times or dynamic updates.
Developing with AJAX can be challenging, especially for developers unfamiliar with asynchronous programming, increasing the complexity of web projects.
Dynamically loaded AJAX content can be difficult for search engines to index, potentially impacting the site’s search engine rankings.
Without proper safeguards, AJAX applications are vulnerable to security threats such as cross-site scripting (XSS) and cross-site request forgery (CSRF).
AJAX-driven content changes often don’t update the URL, which can cause issues with browser back buttons and bookmarking, leading to a less intuitive user experience.
Ajax can be utilized in many cases where small amounts of data should be stored or received from the server without having to reload the whole page. Thus, web owners can deliver a far more seamless experience when browsing the entire store.
Still, developing a feature for web applications from scratch can cost time and effort. But don’t worry since there are many well-built extensions using Ajax technology out there.
All you need to do is download and install the modules that fit your needs to use. So below are some extensions with the usage of Ajax technologies for your Magento 2 stores.
As mentioned earlier, lazy loading is a term given to Ajax coding used to speed up the rendering process on a website. A Magento 2 Lazy Loading extension, as its name suggests, improves the web load speed by displaying web images only at the demanding time.
The Lazy Loading module applies the Ajax technology for loading images. In particular, the module helps you:

The Ajax technology used in this module improves web responsiveness and delivers faster loading on every touchpoint.
