Nodejs: npm throwing error when using monk - node.js

Question

I'm building a NodeJS app using ExpressJS framework.
I'm trying to use monk to connect to MongoDB
var monk = require('monk');
var db = monk('localhost:3000/nodeauth');
When I do npm start , I'm getting the following error:
npm start

I already have a MongoDB database nodeauth and also have some contents in it. mongod service is also running.
P.S: If I remove the above two lines of codes and do npm start , there is no error and I'm able to see the express welcome page at localhost:3000

Answer 1

Check your MongoDB port where it is running. if you did not change the default port , it should be http://localhost:27017/nodeauth
I think your app is running on 3000 port. so, check the mongod port and check again.

Answer 2

omit he port number for monk module. try this way.
var db = require('monk')('localhost/nodeauth');
