npm install

To run the app

Start mongodb using replicaSets

mongod --replSet rs0 --port 27020 --dbpath ./data/r0s1

mongod --replSet rs0 --port 27021 --dbpath ./data/r0s2

mongod --replSet rs0 --port 27022 --dbpath ./data/r0s3

Start the arbiter

mongod --port 30000 --dbpath ./data/arb --replSet rs0

Defind roles of mongod servers

mongo --port 27020

Then (in the mongo shell)

rs.initiate()
rs.conf()
rs.add("localhost:27021")
rs.add("localhost:27022")
rs.addArb("localhost:30000")

Start redis server

Open redis-server.exe on your redis folder

Start the nodejs server
