When you implement your own interceptor on Front-End side, you should remember about CORS:

app.use(function(req, res, next) {
    res.header('Access-Control-Allow-Origin', req.headers.origin || "*");
    res.header('Access-Control-Allow-Methods', 'GET,POST,PUT,HEAD,DELETE,OPTIONS');
    res.header('Access-Control-Allow-Headers', 'content-Type,x-requested-with,authorization123456,accept');
    next();
});

We should remember to set Acces-Controll-Allow on Methods as well as on Headers. In my case it's 'authorization123456' where I put my token which is added to every request from AngularJS.
