Global variables for node.js standard modules?

Question

I know that global variables are bad.

But if I am using node's module "util" in 40 files in my framework, isn't it better to just declare it as a global variable like:

util = require('util'); 

in the index.js file instead of writing that line in 40 files?

Cause I often use the same 5-10 modules in each file, that would save a lot of time instead of copy paste all the time.

Isn't DRY good in this case?

You could just have a common module.

common.js:

Common = {   util: require('util'),   fs:   require('fs'),   path: require('path') };  module.exports = Common; 

app.js:

var Common = require('./common.js'); console.log(Common.util.inspect(Common));
