Modern Full-Stack Development

bundledDependencies – Some projects need to preserve NPM 
packages locally or through a single download. For those, this 
element allows you to specify an array of package names that will be 
bundled with your package when you publish it.
• 
config – If you need to have parameters available in the environment 
when your package is used, then the config element might do the 
trick. Here, you can specify a value like "config" : { "port" : 
"8888" } and then in your code you can reference npm_package_
config_port as an environment variable to get the value configured.
