mongo-col's Introduction

mongo-col

mongoDB collection wrapper

Status: production ready

Example

With mongo-db native

var Db = require('mongodb').Db,
    Server = require('mongodb').Server

var db = new Db('integration_tests',
    new Server("127.0.0.1", 27017, {
       auto_reconnect: false,
       poolSize: 4
    }))

db.open(function(err, db) {
    db.collection("CollectionName", function(err, collection) {
        collection.insert({hello:'world_no_safe'}, function () {
            collection.findOne({hello:'world_no_safe'}, function(err, item) {
                assert.equal(null, err)
                assert.equal('world_no_safe', item.hello)
                db.close()
            })
        })
    })
})

With mongo-col

var collection = require("mongo-col"),
    CollectionName = collection("CollectionName", "integration_tests")

CollectionName.insert({ hello: "world_no_safe"}, function () {
    CollectionName.findOne({ hello: "world_no_safe"}, function (err, item) {
        assert.equal(null, err)
        assert.equal('world_no_safe', item.hello)
        CollectionName.close()
    })
})

Motivation

Setting up a mongodb database connection requires too much callback soup, remove it.

Documentation

collection(collectionName[, databaseName])

collection takes a collection name and returns a collection object. This collection object has all the mongodb collection methods and sets up a database connection internally

See the MongoDB collection API

var collection = require("mongo-col"),
    Users = collection("Users", "optionalDatabaseName")

Users.insert({
    name: "foo",
    password: "bar"
})

You can optionally pass in a databaseName as a string or an instance of a mongodb database object.

`find(query, callback)` callback fires twice

Second invocation is (null, undefined)

How to use MongoDB's ObjectID

Hi!

I'm trying to do this kind of thing (that I used to do with MongoJs)

this.update({ _id: this.ObjectId(project._id) }, {
  $set: { code: project_code, name: project.name }
});

Is there any equivalent with mongo-col?

Thanks!

MongoClient is pretty cool

function mongo(collectionName, databaseName) {
    var cachedCollection
    var queue

    return getCollection

    function getCollection(callback) {
        if (cachedCollection) {
            return callback(null, cachedCollection)
        } else if (queue) {
            return queue.push(callback)
        }

        queue = [callback]

        console.log("uri", config)

        MongoClient.connect(config.DB_URL, {}, function (err, db) {
            if (err) {
                throw err
            }

            var col = db.collection(collectionName)

            queue.forEach(function (f) { f(null, col) })

            console.log("db.db?", db.db)
        })
    }
}
