The documentation above suggests that
$args['script']and$args['style']will be loaded for the “front end”, however in fact it is loaded for both the editor and the front end. If you want certain scripts and styles to be loaded in the front end only, you have to independently load those after a conditional check. UnfortunatelyWP_Block_Type::__construct(and soregister_block_type()andregister_block_type_from_metadata()) does not support loading scripts or styles exclusively for the front end.Top ↑
Feedback
Untested, but possibly checking
is_admin()in those methods would work as a constraint for the frontend. — By crstauf —$args['script']works in WP 5.8 if the handle of the script used inwp_register_scriptis passed. Don’t add the source here but register the script first via thewp_enqueue_scriptsfilter. — By Xaver Birsak —Note that the new to 5.9 view_script parameter only loads the script if render_callback is not defined. See /wp-includes/class-wp-block.php:266:
if ( ! empty( $this->block_type->view_script ) && empty( $this->block_type->render_callback ) ) { wp_enqueue_script( $this->block_type->view_script ); }
