How to reload a Node.js script from under the same script?

Question

Google

Sometimes you need to reload a Node.js script. The client sends a GET requesting a reboot, the server reboots and re-establishes communication with the client. How to organize the reloading of Node.js with a simple command in the script itself? (Not reload when changing script) There are no similar modules in Google and NPM :(
UPD: You can kill the process with a native command, process.exit(0)but then how to restart the process?
