How to use node-ga with routes instead of as a middleware. Based on the third example from http://expressjs.com/api#app.VERB ("Several callbacks may also be passed, useful for re-using middleware that load resources, perform validations, etc.")

node-ga-routes.js

var ga = require('node-ga')('UA-XXXXXXXX-Y', { safe: true});
    
/* your usual express options */

app.get('/logged-route', ga, LoggedRouteHandler);
app.get('/non-logged-route', NonLoggedRouteHandler);
