Embed JavaScript File Content

In some critical cases you cannot wait for a JavaScript file to load. Then you can benefit from better performance, if you embed the JavaScript code directly into the <script> tag. This is where this plugin comes in: It provides a filter embed_javascript_file_content_handles, which takes JavaScript handles and echos their code content into the DOM instead of linking to a file. Please beware that placing lots of embedded JavaScript code can be critical! First you lose caching benefits and second the document size can increase easily. A general rule of thumb is that you should only consider JavaScript files for inline placement, which are critical and which have a file size lower than ~500 Bytes. Example ` add_action( 'wp_enqueue_scripts', 'my_scripts' ); function my_scripts() { // Some critical script is enqueued wp_enqueue_script( 'js-detection', get_template_directory_uri() . '/js/js-detection.js' ); } /**

• Define JavaScript handles to be echoed inline in the html head section. */ add_filter( 'embed_javascript_file_content_handles', 'my_embed_javascript_file_content_handles' ); function my_embed_javascript_file_content_handles( $handles ) { $scripts = [ 'js-detection' ];

return array_merge( $handles, $scripts ); } `
