lately I’ve been ask a lot about
node.js -g command
and what does it do.
It is actually referring to npm -g command which is used to install node.js modules globally,
this means that the module is accessible from anywhere in a command line window (CMD) regardless of the current directory we reside in.
To install a npm package or node.js module globally we can use the following:
$ npm install -g package-name
It is important to understand that the -g usually used for when the node.js module or package is used through command-line utilities
to put the module in bins in the system PATH, where you can execute a specific node.js command through command-line utilities
and it is not used for
for example to install the popular simple http server module globally we can use:
$ npm install -g http-server
once this module is installed, you can navigate to any folder, typically a website content folder, and run http-server command
and server the content of the folder to your local network.
I usually use this node.js module to test my website development and/or share files between different devices through Wi-Fi
