How to define this 'user'

meto

I added some code in the UserSerializer.php file to get the statistics.
Then try to modify the app.js file (In the System.register ('flarum/components/indexPage' section)

          key: 'RightItems',
          value: function RightItems() {
            var items = new ItemList();
            var user = app.session.user;

            items.add('nav', m(
              'div',
              { className: 'ButtonGroup' },
              ...
             'span',
                  { className: 'countTitle countMun' },
                   user.data.attributes.totalUser
                   )

Here I can only use var user = app.session.user; make it work, but this program only applies to registered users.
Does someone have a clue let it work in the visitor？
(I'm just a graphic designer and I know very little about php and js ?)

What are you trying to achieve ? What additional data did you add to the serializer ?

And by the way, you should not touch Flarum files directly. Use an extension to inject new links and sections in the forum. Any Flarum or extension install/update could erase all your changes if you touch the core.

Make a extension it was too hard for me.
the picture is the forum statistics (total user, total discussions, total Comments, online user).
I added something to the serializer like this:

            'totalDiscussions' => (int) $user->sum('discussions_count'),
            'totalComments'    => (int) $user->sum('comments_count'),
            'totalUser'        => (int) $user->sum('is_activated'),

But it can only be displayed to registered users, can't be displayed to visitors.
I can not find the code to var the user, let it displayed to everyone.

Every serializer has the $this->actor which is the currently logged in user, see:

https://github.com/flarum/core/blob/master/src/Api/Serializer/AbstractSerializer.php#L34

If you want to show the statistics of the Post Author, you'd best extend the UserSerializer:
