Answer 1

In my ~/.bashrc, I have the following:

function nbin {
  local dir;
  dir=$(npm bin)
  if [ -d "$dir" ]; then
    ( # subshell to not change this shell's $PATH
      PATH=$dir:$PATH
      eval "$@"
    )
  else
    echo "\"$dir\" is not an npm binary directory." >&1
    return 1

}

nbin foo
