npm install module
npm uninstall module

• This will install in the node_modules folder in the directory where the package.json can be found
• And it will add the name of the package to packege.json as well declaring it as a dependency
• It will also create a file called package-lock.json.
• Both json files should be added to git and the node_modules/ directory should be added to gitignore
