Node cross process communication

cross-processA.js

// One Process needs to be the host
const ipc = require('node-ipc');

ipc.config.id = 'a-unique-process-name1';
ipc.config.retry = 1500;
ipc.config.silent = true;
ipc.serve(() => ipc.server.on('eventName', message => {
  console.log(message);
}));
ipc.server.start();

cross-processB.js

//Now other processes can send messages to it
const ipc = require('node-ipc');

ipc.config.id = 'a-unique-process-name2';
ipc.config.retry = 1500;
ipc.config.silent = true;
ipc.connectTo('a-unique-process-name1', () => {
  ipc.of['jest-observer'].on('connect', () => {
    ipc.of['jest-observer'].emit('eventName', "Content Message");
  });
});
