Potential feature: support wildcard in preload file name

I’m not convinced to be honest; I understand it would be handy, but it would lead to more files being preloaded and preloading should be used (very) sparingly really to prevent it from … slowing down the site rendering ??

If badly used yes, but if properly used it could preload the cached dynamic generated files that are critical and be a great booster.. and appealing to educate perhaps with a warning? Actually I discovered that Wp-rocket plugin supports it, would be nice if Autoptimize allows it as well.. or maybe just an option to preload cache, that would do and no improper use perhaps

but typically (with “critical CSS” and deferred -or delayed- JS) the cached dynamic generated files are not needed for the initial rendering so preloading those would be counter-productive as that takes away bandwidth (esp. on mobile)?

Question: and preloaded critical CSS? or there’s no benefit there? And maybe the other scenario would be cached CSS files without critical CSS?

no; critical CSS is inlined, it’s not a separate file to request ??

the problem; either CSS is aggregated, in which case you would preload way too much, or CSS is not aggregated, in which case you’ll have to find out for yourself what files need to be preloaded. critical CSS cleary is the way to go here, … ??

Right, srry forgot that..

or CSS is not aggregated

I see. Im going a bit offtopic here but maybe I found a bug :O I was analyzing the two css files that have the autoptimize_single_ prefix on my site and it seems that the same css file “main.css” is being loaded as unminified and minified with the above prefix.

Maybe is because it is being preloaded in the head? wich is causing this kind of loaded duplicated style?

<link rel="preload"  as="style">

indeed; if you’re preloading you’ll have to preload the autopitmize_single one ??

And will the name change upon clearing the cache?

Also can be the duplicated style avoided if preloaded or nothing to do there? Thanks ??

if soemthing (even one letter) changes in the original code, yes it will change (because the “random” part of the filename is an (md5-)hash of the contents).

In AOPro you can configure it to remove specific files but that only makes sense if the file is entirely unused (for all devices, on all pages).

Alternatively there’s the “Rapidload” service (see “optimize more” tab) which has pretty complex logic on their own servers to remove unused CSS.

Understood, thanks! ??
