script-loader.php

Last change on this file was 61469, checked in by westonruter, 8 hours ago

Themes: Use WP_HTML_Tag_Processor to insert the block template skip link instead of JavaScript.

The skip link now works when JavaScript is turned off.
By removing the script, the amount of JavaScript sent to the client is reduced for a very marginal performance improvement.
A new wp-block-template-skip-link stylesheet is registered, with minification and path data for inlining.
The CSS for the skip link now has an RTL version generated, although it is not yet served when the styles are inlined. See #61625.
The wp_enqueue_block_template_skip_link() function now exclusively enqueues the stylesheet since the script is removed.
For backwards-compatibility, the skip link will continue to be omitted if the_block_template_skip_link() is unhooked from the wp_footer action or wp_enqueue_block_template_skip_link() is unhooked from wp_enqueue_scripts.

Developed in https://github.com/WordPress/wordpress-develop/pull/10676

Follow-up to [56932], [51003].

3	* WordPress scripts and styles default loader.
4	*
5	* Several constants are used to manage the loading, concatenating and compression of scripts and CSS:
6	* define('SCRIPT_DEBUG', true); loads the development (non-minified) versions of all scripts and CSS, and disables compression and concatenation,
7	* define('CONCATENATE_SCRIPTS', false); disables compression and concatenation of scripts and CSS,
8	* define('COMPRESS_SCRIPTS', false); disables compression of scripts,
9	* define('COMPRESS_CSS', false); disables compression of CSS,
10	* define('ENFORCE_GZIP', true); forces gzip for compression (default is deflate).
11	*
12	* The globals $concatenate_scripts, $compress_scripts and $compress_css can be set by plugins
13	* to temporarily override the above settings. Also a compression test is run once and the result is saved
14	* as option 'can_compress_scripts' (0/1). The test will run again if that option is deleted.
