I'm trying to follow a tutorial on NodeJS. I don't think I missed anything but whenever I call the process.env.NODE_ENV
the only value I get back is undefined
. According to my research the default value should be development
. How is this value dynamically set and where is it set initially?
process.env
is a reference to your environment, so you have to set the variable there.
To set an environment variable in Windows:
SET NODE_ENV=development
on macOS / OS X or Linux:
export NODE_ENV=development
