pass additional parameters to routes (expressjs)

Having started working with express recently I have stumbled across the following problem:

The entire logic of my routes is defined in separate files which are then included by means of require(route_name). The respective get / post matches are done as follows:

app.get('/', routes.home) etc.

The line above implies that routes.home is a function called with the parameters req, res & next.

I have a bunch of utility functions stored in the utils object that I want every route to be able to access. Until now, I've been solving the problem as follows:

var utils = ...

app.get('/', function (req, res, next) {
  routes.home(req, res, next, utils);
});

Is there a way to tell express that it should pass the utils object as a parameter to every route or generally a better solution to my problem?

Thanks for all the answers. I've found a solution to my problem by calling an "init(utils)" function on routes I want to have to the utils module.

I agree with JohnnyHK. And also why do you need to pass res and req twice? Why not do this in your app file:

app.get('/', routes.home);

And then in your required file something like this:

var utils = require('utils')
exports.home = function(req, res){
    //code
}
