Tips for Writing Portable Node.js Code

Node.js core does its best to treat every platform equally. Even if most Node developers use OS X day to day, some use Windows, and most everyone deploys to Linux or Solaris. So it's important to keep your code portable between platforms, whether you're writing a library or an application.

Predictably, most cross-platform issues come from Windows. Things just work differently there! But if you're careful, and follow some simple best practices, your code can run just as well on Windows systems.

Paths and URLs

On Windows, paths are constructed with backslashes instead of forward slashes. So if you do your directory manipulation

Using react-motion with react-router
import React, { PropTypes } from 'react';

/**
* One example of using react-motion (0.3.0) within react-router (v1.0.0-rc3).

* Usage is simple, and really only requires two things–both of which are
* injected into your app via react-router–pathname and children:
*
* <RouteTransition pathname={this.props.pathname}>
