Node itself doesn't care what the environment vars are really, it just lets you read and write them via http://nodejs.org/docs/latest/api/process.html#process_process_env . --Josh On Sun, Mar 18, 2012 at 11:14 AM, dale tan <wtd...@gmail.com> wrote: > I'm not sure where it is documented, but it enables you to define different > environments. > Say you want a "dev" and "prod" environment.
