I have yet to see any problem, however complicated, which, when you
looked at it in the right way, did not become still more complicated.

On Mar 28, 2013 Dan Allen explained how to deploy to github-pages automatically. Many other GitHub users like Steve Klabnik and Domenic Denicola followed with the same approach:

Use an OAuth token with public_repo or repo permission to access the Github account over HTTPS inside a virtual build environment.

The same applies to Travis CI's built-in abilities, and there are more restrictions as deploying GitHub Releases works only for tags, not for branches.

Security concerns

The token grants write access for all of your (public) repositories and

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
