Get seperate process by pid nodejs

Question

Is there a way to get a process by it's process id in node.js? You have the default process object in node, something similar to that object, but i can get an existing process on the system. Something like:var otherProcess = getProcessById(12345)

Answer 1

check find-process library maybe help you

you can find process by pid:

const find = require('find-process');

find('pid', 12345)
  .then(function (list) {
    console.log(list);
  }, function (err) {
    console.log(err.stack || err);
  })

EDIT:

for communication between process you can use ipc (inter process communication) check node-ipc npm package
