When To Use Ajax To Increase Website Performance

What is Ajax?

AJAX, which stands for asynchronous JavaScript and XML, is a set of client-side technologies for asynchronously sending and retrieving data from the server.

AJAX enables us to make changes to the content of a web page without having the user reload the entire page. This can be handy for auto-completion in a search bar or form validation, for example. You can increase your site’s performance, reduce server load, and improve the overall user experience if you implement it appropriately.

AJAX is a programming technique that employs the XMLHttpRequest (XHR) object to asynchronously communicate with a server and create dynamic web pages. Although the terms AJAX and XMLHttpRequest are frequently used interchangeably, they are not the same.

AJAX uses the following stages to send and receive data to and from a web server –

Create an object called XMLHttpRequest:

  • To communicate data asynchronously between the client and the server, use the XMLHttpRequest object.
  • To process the data, use JavaScript and the Document Object Model (DOM).
  • The ajax method in jQuery can be used to implement AJAX, however, the native Fetch API is far superior because it has a cleaner interface and doesn’t require a third-party library.

When to use AJAX?

AJAX can help you increase the performance of your website while reducing server load and increasing the overall user experience. However, it adds a significant amount of complexity to your application. As a result, you should only utilize AJAX when it’s required, unless you’re using a Single-page Application (SPA) like React, Angular, or Vue.

When you should use AJAX, consider the following scenarios:

  • Auto-completion of search terms
  • Validation of the form
  • Sorting and filtering tables
  • Surveys and polls with captchas
  • In general, if the material has to be changed often based on user activities, you should consider using AJAX to update portions of the web page rather than refreshing the entire page.
