How to use different assets if local or live

Question

WordPress has constants that can be defined in the wp-config.php. Have a read here

Something like this might help

//setup the production names for the files
$js_file="scripts.min.js";
$css_file="styles-compressed.css";

//check for WP_DEBUG constant status
if( defined( 'WP_DEBUG' ) && WP_DEBUG ) {

    //check for SCRIPT_DEBUG constant status
    if( defined( 'SCRIPT_DEBUG' ) && SCRIPT_DEBUG ) {
        $js_file="scripts.js";
        $css_file="styles-development.css";
    }
}

//load the files
wp_enqueue_script( 'plugin_scripts', $basepath . '/js/' . $js_file  );
wp_enqueue_style( 'plugin_styles', $basepath . '/css/' . $css_file  );
