Does the plugin?
-
Does the plugin automatically replace jquery and those wp core js? that are on cdnjs
-
Not automatically – you must select which files you want to replace. Once you do that, it will replace them automatically for you.
Is that the sort of functionality you were looking for?
Cheers,
Paul.Actually I agree with Acrogenesis, what would be useful is a scan on js in WP installation, compare with CDNJS archive and present to admin saying: “These scripts, used in your installation, are available in CDNJS repository, want you replace them?”.
Seems completely useless, time consuming and newbies confusing show the whole archive without know what effectively it’s used in that installation, don’t you think so?
This is not a critique, only an advice for future upgrades.
Thanks to develop and share this plugin.Mac
Thanks for the suggestions…
The problem is that there’s no way to just “scan” someone’s theme + plugin to determine what they have. Just because there’s resources present, doesn’t mean they should be included on the site.
To learn what is included in an installation, a user can load their site, view their source, and pick out the files such as jquery and then go to the plugin and replace them. Nothing useless or confusing about that.
Many sites don’t even include Jquery by default as it’s not needed.
If you know a way to easily “scan” a WordPress site and determine the full list of Javascript/CSS includes I’d happily take that code and put into the plugin.
One option is to manually compile a list of files that WordPress ships with and offer to replace those, but that would mean “newbies”,as you say, would unknowingly start including loads of files they don’t even need which defeats the purpose of the plugin – which is to speed up a site.
This option would also mean it’d need updated upon each WordPress release. That’s a lot of manual work.
Fundamentally, it’s a great suggestion, and in a perfect world where it is easy to code something like, it’d be awesome. But that’s way beyond my skills – unless someone can contribute know-how and expertise to doing this. I’m always open to it.
Many thanks for the feedback, and I’m sorry if the plugin doesn’t meet needs as I hoped it would. But if it is serving you well, please feel free to help raise its profile by giving it a nice positive review on wordpress.org… that would always be appreciated. 🙂
Many thanks,
Paul.Hi Paul,
thanks for answering and for this plugin 🙂
As you say, in a “perfect world” this should be the ideal condition but I cannot help on this because I’m not a skilled dev and don’t have a method to scan js files.
What can I see is that if I test a site with i.e. GtMetrix, it shows me a list of used js files, so for sure a method exists but I don’t know which one.
Hope that somebody can help, because could be really useful to easily substitute js scripts, meanwhile I’ll try to manually find them from the list.
Thanks a lot for assistance.Mac

Seriously? Even that sentence was confusing and useless because I have no idea where any of that is or how to do any of that.
Just because some of us know to look for plugins & methods to speed up our sites, by no means, means that we have any sort of programmer or developer skills or knowledge…that’s precisely why WP is so popular.
You say that figuring out how to scan a site for code is beyond your skill level; try being a person with no coding knowledge that installs your plugin and then is faced with 100 options, none of which we’ve ever heard of…and zero instructions beyond install and then click activate!
Perhaps, at the very least, you could put together a guide & tutorial, maybe even a Help file, so that non-coders could possibly try and follow your above suggestions for finding this stuff and telling which kind is which kind, because we have no idea. Install, activate, choose stuff is not instructions when it comes to something like this.
I installed this plugin because I have an all video site which, as you can imagine, needs all the load speed help it can get. I have W3 Total Cache & Cloudflare both on it, and they help massively, but I still get “D” ratings for static content caching over on WebPageTest.org. It seemed like your plugin would seriously help with this, but it can’t be helpful if I can’t implement it, lol!
Please consider putting together some sort of guide/help/tutorial for non-coders that really would like to use this to make their sites faster. If you did that, so many more people would use this. And from what I’ve read, the more people adopting CDNJS, the better it can work.
Thank you for creating this plugin, and I look forward to possibly using it at some point, lol!
Yep, seriously. 🙂
The sheer scope of writing a guide for this is huge… but I can give you the basics.
– Load your website’s homepage
– view the source (right-click, view source)
– search for Javascript files. All the lines like this:<script type=”text/javascript” src=”http://ABCD.com/XYZ.js”></script>
You want to make a note of all the files like: XYZ.js
Now take your list and have a look to see if there are any files on the list that are also on the list of CDNJS files.
If they are, try enabling that particular option.
Then reload your page. And see if that file has been replaced by a link to a CDNJS file.
That’s the basics. 🙂
Hi Paul,
Thank you so much for getting back to me! This is Perfect! See? That wasn’t so hard to explain! Try adding a file just like this to the Help file for the plugin and people like me could start using it right away!
I just clicked “View Source Page” from the right click contextual menu, then right clicked again and selected “Find Again”, typed “.js” into the searchbox, clicked “highlight all” and then quickly matched the XYZ.js extensions against the list of libraries in the plugin. I did this on a good, average, sampling of my pages & posts to make reasonably sure I found at least the majority of the .js files that had matching libraries available in your plugin.
There were just a couple that weren’t available, yet. I’ll just give the quick list, do with it what you will…
Missing: ga (google analytics), gritter, combined, show-excerpt, detect-mobile, tracker, video, jRating, and colorbox.Now, about the .css libraries…. I tried the same process with searching “.css” but found nothing that matched the css libraries available in the plugin. Since there are only maybe 5 choices for css libraries in the plugin, does this work the same as the .js libraries, or are the css selections some sort of over-arching libraires?
Again, thank you for getting back to me with a simple to understand and simple to implement answer. That was all I needed and I bet others would really benefit (as would CDNJS) from this kind of info being readily available right with the plugin.
Have a great week!
cF early adopter, love it
Question: I have font-awesome as part of my theme (not a plugin). Does it still make sense to add/load it from CDNJS with your plugin to speed things up?
thx
Glad this helped you out! I’ll perhaps put this on the FAQ page when I update the plugin again.
@stu, it depends on how your theme is enqueueing the font-awesome… the next update to this plugin would allow you to customize under what name the script is enqueued so you can better replace what is in your themes.
jsDelivr plugin has a scan mechanism (but doesn’t find many matches :)) maybe you can implement it better
