npm restart [-- <args>]
This restarts a package.
This runs a package's "stop", "restart", and "start" scripts, and associated
pre- and post- scripts, in the order given below:
Note that the "restart" script is run in addition to the "stop"
and "start" scripts, not instead of them.
This is the behavior as of npm major version 2. A change in this
behavior will be accompanied by an increase in major version number
