Remove Render-Blocking JavaScripts

I think some hack can help here. We can intercept widget contents before they are rendered and include delay in all script tags. A small plugin can handle it.

So, once admin's views dont require defer scripts, we could try new approach too, using a "cloned" _root view with fixed scripts included, then the number of views we need to check will decrease a lot.

What do you think?

I am not a huge plugin fan but we need to find solution for everyone.If we can do it for google analytics and yandex metrika without interrupting them, why not :)

There are still parts that i didn't understand on eurodress's method. Since he is working on it more than anyone else and tested it, I am sure he has a good solution. I didn't have a chance a try his solution yet. I understood the inline script part.

The only part I didn't understand;

we are changing the generate scripts method in PageHeadBuilder.GenerateScripts. So it is defering all js. how we separate the ones  required for loading the libraries?

When I analyse my page with https://developers.google.com/speed/pagespeed/insights/
all google bots are interest in the scripts we call from _Root.Head with Html.AppendScriptParts and Html.AddScriptParts.

I hardcoded that now.

But anyway, it's still buggy, and takes too much time. For other reasons as well I'm now looking into migrating to Prestashop.

Well, it passes the javascript blocking test in Google Pagespeed without any code change. Just enabled a setting, and it worked. 73/87 score on Google Pagespeed!

It has modules for Poli (NZ & AU payment option), nopCommerce does not have.

Sorry guys, but this change just took too long and became too hacky.

I believe it and I belive that a lot of another e-commerces do it too. The point is, PHP is an old language with some big problems, security, performance issues.

If you want to find a better solution, you must consider a big list of important requirements.

Thats is it.

I think there was something else slowing down your speed. Without Remove Render-Blocking JavaScripts/CSS my current speed is 88 and i have a megamenu with category pics on the website. I don't think it is just Nopcommerce.

when i remove the megamenu pics it goes up to 90-91
