This article assumes you have Node.js and NPM installed.
Similar to Ruby and it’s gem methodology, Node.js has a structure of installing libraries through NPM.
Installing to a Single Project
Simply go to the directory of your project and type the command
npm install [library name]
you can also use npm uninstall [library name]
This installs the library or framework into the project you’re currently in.
Global Installs
To globally install a framework or library, you run the same command with the -g param. For example:
npm install [library name] -g
Searching for Libraries
If you aren’t sure of what version or what the exact name of a library you’re looking for is, you can search the npm repositories with:
npm search [library name]
