Dynamic require in Nodejs

I'm requiring a library in NodeJS which has a self-invoking function, that results an error because it looks for an object which is not initialized at that moment .

I want to dynamically require this library when that object is initialized.

Is there any way to dynamically require/ load a library ?

This is the part of library required : https://github.com/sakren/node-google-maps/blob/develop/lib/Google.js#L5

Actually I want to require when the window object is present (client-side rendering).

So something like this : 

'use strict';

var React = require('react');
var Map = require('./map.jsx');
var Common = require('../common/common');
var MapStatic = require('./map-static.jsx');

exports.type = function() {
    return 'map';
};

exports.jsx = function(data) {
    if (Common.isServerSide()) {
        return (<MapStatic data={data}/>);
    } else {
        return (
            <Map data={data}/>
        );
    }
};

exports.transform = require('./map-transform.js');

The reason the code looks weired is that I'm using react.

In nodeJS require can be used anywhere at anytime whithout much limitations AFAIK.

Which error is thrown once you require at runtime ? In your else branch.

Try the following.

requires = {}
function getter(key) {
  if(!requires[key]){
    requires[key] = require(key)
  }
  return requires[key]
}
