npm edit <name>[@<version>]
Opens the package folder in the default editor (or whatever you've
configured as the npm editor config -- see npm help config.)
After it has been edited, the package is rebuilt so as to pick up any changes in compiled packages.
Note: If you're finding yourself using this a lot, it's probably better
to use npm link instead. However, it is extremely handy when used in
conjunction with npm bundle.
For instance, you can do npm bundle install connect to install connect
into your package, and then npm bundle edit connect to make a few
changes to your locally bundled copy.
Default: env.EDITOR
The program to use to edit files.
