In a NodeJS application ,I have finished some modules,Now I want to use them in Meteor,What should I do?
For example,there is a file 'hello.js',content:

```
require('url');// In here,require other modules
function sayHi(name){
       console.log("Hi "+ name);
}
exports.sayHi = sayHi;

```

How do I use 'say Hi' in meteor?

when I do this:

```
if (Meteor.isServer) {
       Meteor.startup(function () {
       var require = __meteor_bootstrap__.require;
       var index = require('./hello');
       hello.syaHi('Ec');})}

```

Errors is:

```
