I want to run eslint as part of my checks
so one of my dependencies is
npm install -g eslint
but this sometimes fails due to network error.
however in reality it would be easy to have this in the cache and not always install it.
I’ve found a mechanism to install only once, but this would require an exceedingly long command line, or preferrably a means to define a shell function. http://stackoverflow.com/a/30668666/109175
is there a way to define a shell function? Or is there a better way to only install a node module once?
