Hi. I'm writing a simple script that is meant to connect to mongo and insert some records.

Here's what I came up with:

var db; // shared connection
var url = 'mongodb://localhost:27017/project'
MongoClient.connect(url,

, function(err, mongoClient) {
if(err)

db = mongoClient;
});
// TODO mongoClient.close();

My script starts up mongo and tries to connect immediately.
It turns out that there's a delay between mongo startup and the point of time when it opens a socket connection.

So my script fails with "Error: connect ECONNREFUSED 127.0.0.1:27017"

Is it an expected behavior?
I don't believe that it can't recover from such an error.
Maybe I don't understand something.
