WP-Rocket Footer JS

WordPress plugin to force all JS to the footer including inline scripts. Depends on WP-Rocket This is NOT an official addon to WP-Rocket!

This plugin will combine all inline and external JS in the order found on the page and save it to WP-Rocket's cache folder as a new file. All localized scripts are excluded and combined to one script, placed before the external script tag.

1.3.0

  • Auto optimize Tawk.to, WP Rockets lazyload, and google analytics to use normal tags instead of javascript loaders so they can get minified
  • If minify is enabled due to LazyLoadXT or A3_Lazy_Load support, then lazy load facebook, twitter, google plus widgets, and avada google maps (if Avada_GoogleMap exists and google maps is on)
  • Enqueue LazyLoadXT widget extension if lazyload is enabled since lazy load plugins don't supply it
  • Improve lazy load regex patterns
  • Split minify to rocket_footer_js_process_remote_script and rocket_footer_js_process_locate_script functions with associated filters to hook into
  • Minify emojione in tawk.to JS
  • Add hook rocket_footer_js_rewrite_js_loaders to allow pre-processing before minification
  • Add support for avada google maps lazy loading
  • Remove duplicate google maps API scripts and prioritize the first one that has an API key
  • Only lazy load google maps if there is any script content
  • Added function rocket_footer_js_lazyload_script to reduce code duplication

1.2.3

  • Ensure url scheme is set correctly when converting from a CDN domain

1.2.2

  • Disable minify on AMP pages

1.2.1

  • Tested on WordPress 4.7
  • Ensure PHP 5.3 compatibility

1.2.0

  • Correct/improve relative URL logic
  • Prevent html from being minified before JS to prevent issues with detection
  • Add new minify cache system to reduce computation time required to minify a page

Notice: This new cache system could cause unknown issues. While it has been tested, not every situation can be accounted for. Contact me if you hit a problem.

Notice: Cache is stored in transients, so only a normal wp-rocket purge will clear everything

1.1.16

  • Fix logic bug in data-no-minify check

1.1.15

  • Check for relative URL's
  • Add compatibility support for "Page Links To" since it does naughty things with buffering

1.1.14

  • Bugfix fetching JS from filesystem with http\Url
  • Add a newline into the automatic semicolon insertion for the case that the last text is a comment

1.1.13

  • Ensure zxcvbn is loaded normally and not async

  • Exclude js template script tags

1.1.11

  • Check for sourcemaps and add a new line to prevent syntax errors

1.1.9

  • Catch errors if WP_Error is returned or status code is not 200 or 304 or its empty
  • Log errors if debug mode is enabled or PHP display_errors is enabled
  • Disable minify when debug is on regardless of settings
  • Log processed scripts in debug mode
  • Move query string check to only run for local files

1.1.8

  • Web fetch dynamic scripts being defined as not having a JS extension
  • Add regex to remove broken conditional comments out of inline js

1.1.7

  • Add constant DONOTMINIFYJS and function is_rocket_post_excluded_option to minify status check

1.1.6

  • If file is external, we do not want to treat the response as a filesystem path
  • Always set the url domain back to home_url() because it will need to be that even if the original is a CDN or not

1.1.5

  • Use home URL and ABSPATH for the site root and not assume everything is in wp-content

1.1.4

  • Use a http_build_url shim as a fallback instead of deactivating with an error

1.1.3

  • Set main script tag to async

1.1.2

  • Minified wrong JS buffer for inline JS
  • Don't prepend semicolon since its already conditionally prepended for inline JS

1.1.1

  • Update code commentation and PHPDoc blocks

1.1.0

  • Changed logic to disable minify setting on front end and combine all scripts + minify if option is set (excluding localized scripts) to a new file in minify cache folder. File name will have user ID if logged in to be unique.
  • Keep application/ld+json in the header

1.0.2

  • Exclude JS extension from slug name and ensure remote file is saved with a JS extension
