I’m trying to display the format and size of a file attached to an article. Its system name is field_file.

So far, I’ve succeeded to load an article in my my_theme.theme file and the field_file field attached to it:

$ article = Node::load($ article_nid); $ variables['file'] = $ article->get('field_file');

then use its uri in a twig file: {{file_url(file.entity.fileuri)}}

Now I’m trying to display its format and size. I tried {{file.entity.format}} and {{file.entity.filesize}} without success.

Does anyone have a clue how to do it? I’m still new to Drupal plugins and entities.
