Connection model for Mongo using Node.js

[Travis Briggs]

Hello,

I just got started with Node.js and I'm trying to use Mongo.

I'm just looking for a basic connection model for Mongo when using
Node.js. I'm using the native driver
(https://github.com/mongodb/node-mongodb-native) and I have the
following for getting a "database object":

At the top of the file I have
var db = new mongo.Db('app_name', new mongo.Server("127.0.0.1", 27017, {}));

Then, inside my request handler:

function handle_request(request, response) {
       db.open(function(err, p_client) {
               db.collection('users', function(err, collection) {
                       ...etc...

So it looks to me like I'm opening a connection for every request.
Should I instead call db.open immediately after initializing it and
use the same connection for multiple requests? Should I actually make
it more individual and define the db object inside the request
handler?

This is preliminary to any discussions as to the optimal model for
extreme throughput, and is more on a par with: how do I ensure that
I'm using the objects correctly, I get correct results and I don't
hang the resources of the process/OS.

Thanks,
-Travis

You should reuse existing connection, i.e. call `open` in initialization. Also there are lots of wrappers that make API of MongoDB Driver more friendly and remove some of callbacks like mongoskin, mongojs or http://alexeypetrushin.github.com/mongo-lite

I just want to add to Alexey's list, Mongoose (http://mongoosejs.com/) is another good option.
