There are a number of node modules that can be useful tools when developing JavaScript or CSS.
In order to use one of these tools, you will first need to download and install Node.js.
Once you have installed node.js, any package can be installed by using the node package manager, npm. Any packages that the package depends upon are also automatically installed.
To install the latest version of myPackage for a single project, type the following into the command line:
npm install myPackage
Alternatively, to install the package globally, include the -g option:
npm install -g myPackage
