node.js - MongoError: connect ECONNREFUSED 127.0.0.1:27017
I'm using NodeJS wih MongoDB using mongodb package. When I run mongod command it works fine and gives "waiting for connection on port 27017". So, mongod seems to be working. But MongoClient does not work and gives error when I run node index.js command-

This happened probably because the MongoDB service isn't started. Follow the below steps to start it:

Go to Control Panel and click on Administrative Tools.
Double click on Services. A new window opens up.
Search MongoDB.exe. Right click on it and select Start. 

The server will start. Now execute npm start again and the code might work this time.
