Wp Rocket tutorial: How to remove unused javascript

Wp Rocket updated its logic for delaying javascript, it now delays all javascript, including inline scripts, and has a default list of exclusions(alongside internal js exclusion list).

Delaying any 3rd party plugins will also fix the Pagespeed “Reduce the impact of third-party” warning.

The textbox now is for placing javascript you want to be excluded from:

Delay Javascript Execution Wp Rocket

The following formulas will be included by default on WP Rocket and exclude essential Javascript to avoid errors:

(?:wp-content|wp-includes)(.*)
/jquery-?[0-9.]*(.min|.slim|.slim.min)?.js
js-(before|after)

The reason behind this formula is as follows:

  • (?:wp-content|wp-includes)(.) – excludes all internal javascript files
  • /jquery-?[0-9.](.min|.slim|.slim.min)?.js – excludes jQuery
  • js-(before|after) – exclude inline scripts. Only inline scripts that are added using wp_add_inline_script() will be excluded.

Delay JavaScript Wp Rocket 3.9 or higher compatibility exclusions

To prevent any issues that arise from using the delay javascript feature, Wp Rocket has a list of plugins/themes/services that you can add now to avoid it, click HERE for the list.

For Wp Rocket version below 3.9, see our legacy guide HERE.

RocketCDN, Wp Rocket’s CDN plugin

RocketCDN is Wp Rocket CDN product. With a unique price of $8 a month, it offers unlimited CDN traffic(at Wp Rocket discretion). It also offers integration with Wp Rocket. Rocket CDN is powered by StackPath which has 45 edge locations around the world.

RocketCDN setup is a simple 1 step task, just activate it after purchase on the Wp Rocket admin panel CDN tab. It also offers integration with Cloudflare.

Can i use Asset Cleanup and Wp Rocket?

You can use Asset Cleanup and Wp Rocket together, but avoid enabling overlapping functionalities from both to not cause issues.
