Easiest way to run a Node script from Ruby?!

node-hi-ruby.rb

require "json"

def execjs(js)
  IO.popen(["node", "--input-type=module"], "r+") do |pipe|
    pipe.puts js
    pipe.close_write
    pipe.read
  end
end

greeting = "Hello Ruby!"

output = execjs <<~JS
  console.info(#{greeting.to_json})
JS
    
if output.strip.length > 0
  puts output # Hello Ruby!
else
  puts "Runtime error in Node script, aborted."
end
