Get current assigned process id in node js

Question

I want to get current process id which is currently used.I'm using cluster for multiprocessing. I need this because I want to kill child process after the use to reduce memory utilise but I only get the current process Id when I call process.exit() method. But I don't want to call process.exit() method in each route and cluster.on('exit') couldn't called.

Answer 1

Process PID can be accessed by process.pid .

Answer 2

built-in/core modules process does this:-

const process = require('process'); // On ubuntu, you dont need this (if there is an error)

if (process.pid) {
  console.log('This process is your pid ' + process.pid);
}
