Using the npm utility we can easily install new modules into our node.js development environment. There are two modes for using the node.js package manager, also known as npm. The local mode is the default one. In order to use the global mode we should add the -g flag when using the npm command.
Using the npm utility we can easily install new modules from node.js public repository. Using npm in the local mode means that we get a copy of the module current version on our desktop saved in a subfolder within our current folder. Using npm in the global mode the module file will be saved together with all other modules that were fetched globally inside /usr/local/lib/node_modules/.
