Hard Reset vs. Soft Reset: When to Use Which Refresh Method in JavaScript?

JS Refresh: Hard Reset vs. Soft Reset

JavaScript provides several methods to refresh a web page, but not all of them fully reload the page. This article explores the difference between hard refreshes, which refresh the entire page including external resources, and soft refreshes, which may load resources from the cache instead of fetching them from the server.

Hard Refresh

To perform a hard refresh via JavaScript, the location.reload() method can be used with the argument true. This forces the browser to disregard its cache and obtain a fresh copy of the page, including all external resources like images, CSS, and JavaScript.

location.reload(true);

Caveats

Note that this solution may not function consistently across browsers. According to MDN, only Firefox supports a forceGet parameter for location.reload(), while other browsers will ignore it.

Soft Refresh

If the location.reload() method is called without an argument or with a false argument, the browser may choose to reload the page from the cache rather than the server. This is to enhance performance by reducing unnecessary network requests.
