ReferenceError: document is not defined when running a production server.

[ShuoShen]

This happens when I'm using the domquery module. The issue can be reproduced in the following four steps:
#1. install the components

$ npm install domquery; npm install matches-selector; npm install closest; npm install event;
#2. change the following file:

--- a/app/Home/index.jsx
+++ b/app/Home/index.jsx
@@ -1,5 +1,6 @@
var React = require("react");
var Link = require("react-router").Link;
+var dom = require('domquery')
#3. run build

$ npm run build;
#4. run start, which gives the error:

$ npm run start

What is the cause of this error? Please help! Thanks.

There is no DOM while prerendering.
Write your components without using the DOM, or
require DOM specific stuff in componentDidMount.

[sokra]

if(typeof document !== "undefined")

[ShuoShen]

Great! That works. Thanks for your help.
