    Usage
      $ find-node-modules-import [file|glob*]
 
    Options
      --module              [String] filter the result by module name
      --builtinModules      [Boolean] filter the result by Node.js builtin modules. Default: false
      --verbose             [Boolean] show warning/error output. Default: false

    Examples
      # show all imports
      $ find-node-modules-import "src/**/*.{js, ts}"
      # show Node.js builtin modules
      $ find-node-modules-import "src/**/*.{js, ts}" --builtinModules
      # show specific module
      $ find-node-modules-import "src/**/*.{js, ts}" --module "lodash"
