Error: failed to connect to [localohost:27017]

I am trying to connect to mongod server to test my connection with node js.

Here is the code for app.js which i am trying to run -

var MongoClient = require('mongodb').MongoClient;

MongoClient.connect('mongodb://localohost:27017/test',function(err,db){

if(err)
    throw err;

db.mycollection().findOne({},function(err,doc){
if(err)
    throw err;
console.dir(doc);
db.close();

});

console.dir('called');
});

When i ran it for first time it gave me an error that mongodb module not found - after i installed

npm install mongodb

I started my mongod server in another cmd. but when i am running node app.js it gives me error -

C:\Users\SONY\Desktop\python pakka\node_modules\mongodb\lib\mongodb\mongo_client
.js:409
          throw err
                ^
