	}
});

// Stream big file in worker thread
Papa.parse(bigFile, {

WP REST API rendered output & Visual Composer

Visual Composer shortcodes are normally not converted within the WordPress REST API rendered output.

This can be accomplished by calling WPBMap::addAllMappedShortcodes();

add_action( 'rest_api_init', function ()
{
   register_rest_field(
          'page',
          'content',
          array(
                 'get_callback'    => 'convert_do_shortcodes',
                 'update_callback' => null,
                 'schema'          => null,
          )
       );
});

function convert_do_shortcodes( $object, $field_name, $request )
{
   WPBMap::addAllMappedShortcodes(); // This does all the work

   global $post;
   $post = get_post ($object['id']);
   $output['rendered'] = apply_filters( 'the_content', $post->post_content );

   return $output;
}

add_action( 'rest_api_init', function ()

{

register_rest_field(

'page',

'content',

array(

'get_callback' => 'convert_do_shortcodes',

'update_callback' => null,

'schema' => null,

)

);

});

function convert_do_shortcodes( $object, $field_name, $request )

{

WPBMap::addAllMappedShortcodes(); // This does all the work

global $post;

$post = get_post ($object['id']);

$output['rendered'] = apply_filters( 'the_content', $post->post_content );

return $output;

}
