XMLHttpRequest vs the Fetch API: What’s Best for Ajax in 2019?
March 2019 celebrates the 20th anniversary of Ajax. Sort of. The first implementation of XMLHttpRequest shipped in 1999 as an IE5.0 ActiveX component (don't ask).
Before then, there had been ways to pull data from a server without a full-page refresh, but they often relied on clunky techniques such as <script> injection or third-party plugins. Microsoft developed XMLHttpRequest primary for a browser-based alternative to their Outlook email client.
XMLHttpRequest was not a web standard until 2006, but it was implemented in most browsers. Its adoption in Gmail (2004) and Google Maps (2005) led to Jesse James Garrett's 2005 article AJAX: A New Approach to Web Applications. The new term crystallised developer focus.
AJAX to Ajax
AJAX is a mnemonic for Asynchronous JavaScript and XML. "Asynchronous" definitely, but:
- JavaScript was likely, although VBScript and Flash were options
- The payload did not need to be XML, although that was popular at the time. Any data format could be used and, today, JSON is normally preferred.
We now use "Ajax" as a generic term for any client-side process which fetches data from a server and updates the DOM dynamically without a full-page refresh. Ajax is a core technique for most web applications and Single-Page Apps (SPAs).
