should_load_block_assets_on_demand │ filter-hook │ WP 6.8.0

Filters whether block styles should be loaded on demand.

Returning false loads all block assets, regardless of whether they are rendered in a page or not. Returning true loads block assets only when they are rendered.

The default value of the filter depends on the result of wp_should_load_separate_core_block_assets(), which controls whether Core block stylesheets should be loaded separately or via a combined 'wp-block-library' stylesheet.

Usage

add_filter( 'should_load_block_assets_on_demand', 'wp_kama_should_load_block_assets_on_demand_filter' );
