On a recent assignment, I needed to install npm behind a corporate proxy. I had already set the environment variables
HTTPS_PROXY. Other command line utilities, like ruby gems, recognized these environment variables. Npm did not.
After some googling, I found the following way to configure the proxy for npm.
If you need to specify credentials, they can be passed in the url using the following syntax.
Further exploration of the npm config documentation showed that the
npm config set command sets the proxy configuration in your
.npmrc file. You can also set the proxy configuration as a command line argument or environment variable.
Configuration parameters can be specified using
-- when executing npm. So the proxy could also be specified as follows.
To pass configurattion parameters to npm as environment variables, they must be prefixed with
npm_config_. The proxy configuration could be set with environment variables as follows.
