how to connect MongoDB in Cloud9?

Question

I have a problem with the connection database MongoDB in Cloud9 Please help to resolve this issue!

var MongoClient = require("mongodb").MongoClient;
var port = process.env.PORT;
var ip   = process.env.IP;
MongoClient.connect("mongodb://"+ip+":"+port+"/test",function(error,db){
        if(!error){
         console.log("We are connected");   
        }
        else{
         console.dir(error); //failed to connect to [127.4.68.129:8080]               
        }
});

Output:

Running Node Process
Your code is running at 'http://demo-project.alfared1991.c9.io'.
Important: use 'process.env.PORT' as the port and 'process.env.IP' as the host in your scripts!
[Error: failed to connect to [127.4.68.129:8080]]

If you follow https://docs.c9.io/setting_up_mongodb.html this link, you will setup and run your mongodb daemon under your workspace.

And if you take a look at the output of ./mongod, you'll find out this output:

2015-08-22T12:46:47.120+0000 [initandlisten] MongoDB starting : pid=7699 port=27017 dbpath=data 64-bit host=velvetdeth-express-example-1804858

Just copy the host and port value to your mongodb config, set up the database url, in this case is:

mongodb://velvetdeth-express-example-1804858:27017
