Distributed micro service master / slave election manager

This package is developed for Nodejs applications using PM2 as a runtime process manager.

Reason for developing this package

If you have 4 applications running in production and want to schedule cron jobs they will run X 4.

This package allows you to identify the current master application in your network and process the job once.

A master node is a healthy instance.

Usage

.env file add the following

MQ_MONGODB_URL=
MQ_MONGODB_NAME=

In your application import

const {isMasterNode} = require("@d19n/node-mq);
