Not sure if you even understand what you're talking about. As for node.js, I set up pm2 to watch for file changes and restart ts-node process and this takes a few seconds, which is slower than I can hit alt-tab back to the browser, which is annoying to see 'Bad Gateway' error page quite often, not to mention embarrassing to explain and help set it up to someone new to other languages than PHP.
