Frontend: Ajax check the modified date every 5 seconds and if there are changes refresh

[cb2004]

Hi all.

My JS/jQuery really struggles towards the end of the week, but I was just wondering if anybody has had the need to check the modified date of a page and if there is new to refresh. If not I will take a stab at it again next week.

Have a good weekend all.

Like a newsticker or newsfeed that updates whenever there is a new post?

I will need something of that kind in a project very soon and looked at a solution with HTMX using polling or SSE. While looking into it I stumbled across something an old thread here:

Haven't had the time to dig deeper but maybe this is good starting point for you.

I was thinking maybe it could be a bit simpler, for me all I need to do is check the modified date every 5 seconds and if it is different to what the page currently says then it just refreshes.

I use htmx polling for that in a monitoring widget. It's only visible for superusers so that was the easiest way.

Don't know if this would actually fit your use case at all.

If you don't want to add a library, why not using a simple XHR? That's only a few line of JS and PHP.
On what part are you struggling exactly?
