How do I check if I am currently logged in on the client side? [complete]

Utilizing Express and Passport, I serve all my files statically in the following manner.

// static bundle from webpack
app.use('/', express.static(__dirname + '/../client-react/dist'));

As a result, when I'm on the client side, I have no way of determining if I am logged in.

Passport is functioning correctly, allowing me to retrieve profile data on the server.

An AJAX request is implemented as follows:

    $.ajax({
      url: "/api/items",
      success: (results) => {
        console.log(results);
        this.props.dispatch({type: 'updateBookmarks', bookmarks: results});
      }
    });
  }

The server responds with:

router.route('/items').get((req, res) => {

    console.log(req.user);

    DB.selectAllDomains().then((results) => {
        res.json(results);
    });
});

When a client is uncertain of the user's login status, they can send a request to your server. If passport integration is successful, your server will have access to req.user and can respond with key/value information. This way, the client can be informed about the logged-in user.
