Introduction

Mongoskin is the future layer above node-mongodb-native

var mongo = require('mongoskin'),
    db = mongo.db('localhost:27017/test?auto_reconnect');

db.collection('user').ensureIndex([['username', 1]], true, function(err, replies){});
db.collection('posts').hint = 'slug';
db.collection('posts').findOne({slug: 'whats-up'}, function(err, post){
    // do something
});
db.collection('posts').find().toArray(function(err, posts){
    // do something
});

db.bind('posts', {
   findTop10 : function(fn){
     this.find({}, {limit:10, sort:[['views', -1]]}).toArray(fn);
   },
   removeTagWith : function(tag, fn){
     this.remove({tags:tag},fn);
   }
});

db.posts.findTop10(function(err, topPosts){
  //do something
});

db.collection('posts').removeTagWith('delete', function(err, replies){
  //do something
});

db.posts.mapReduce(...);
db.createCollection(...);

Is mongoskin synchronized?

Nop! It is asynchronized, it use future.

Module

MongoSkin Url format

[*://][username:password@]host[:port][/database][?auto_reconnect[=true|false]]`

e.g.

localhost/blog
mongo://admin:pass@127.0.0.1:27017/blog?auto_reconnect
127.0.0.1?auto_reconnect=false

bind(collectionName)

bind(collectionName, SkinCollection)

bind(collectionName, extendObject1, extendObject2 ...)

Bind SkinCollection to db properties. see SkinDb.bind for more information.

db(databaseUrl)

Get or create instance of SkinDb.

cluster(serverUrl1, serverUrl2, ...)

Create SkinServer of native ServerCluster. e.g.

var mongo = require('mongoskin');
var cluster = mongo.cluster('192.168.0.1:27017', '192.168.0.2:27017', '192.168.0.3:27017')
var db = cluster.db('dbname', 'admin', 'pass');

pair(leftServerUrl, rightServerUrl)

Create SkinServer of native ServerPair

Back to index

SkinServer

SkinServer(server)

Construct SkinServer from native Server instance.

db(dbname, username=null, password=null)

Construct SkinDb from SkinServer.

Back to index

SkinDb

SkinDb(db, username=null, password=null)

Construct SkinDb.

open(callback)

Connect to database, retrieval native Db instance, callback is function(err, db).

collection(collectionName)

Retrieval SkinCollection instance of specified collection name.

bind(collectionName)

bind(collectionName, SkinCollection)

bind(collectionName, extendObject1, extendObject2 ...)

Bind SkinCollection to db properties as a shortcut to db.collection(name). You can also bind additional methods to the SkinCollection, it is useful when you want to reuse a complex operation. This will also affect db.collection(name) method.

e.g.

db.bind('book', {
    firstBook: function(fn){
        this.findOne(fn);
    }
});
db.book.firstBook:(function(err, book){});

all the methods from Db.prototype

See Db of node-mongodb-native for more information.

Back to index

SkinCollection

open(callback)

Retrieval native Collection instance, callback is function(err, collection).

id(hex)

Equivalent to

db.bson_serilizer.ObjectID.createFromHexString(hex);

See ObjectID.createFromHexString

findItems(..., callback)

Equivalent to

collection.find(..., function(err, cursor){
    cursor.toArray(callback);
});

See Collection.find

findEach(..., callback)

Equivalent to

collection.find(..., function(err, cursor){
    cursor.each(callback);
});

See Collection.find

findById(id, ..., callback)

Equivalent to

collection.findOne({_id, ObjectID.createFromHexString(id)}, ..., callback);

See Collection.findOne

updateById(_id, ..., callback)

Equivalent to

collection.update({_id, ObjectID.createFromHexString(id)}, ..., callback);

See Collection.update

find(...)

If the last parameter is function, it is equivalent to native Collection.find method, else it will return a future SkinCursor.

e.g.

// callback
db.book.find({}, function(err, cursor){/* do something */});
// future SkinCursor
db.book.find().toArray(function(err, books){/* do something */});

all the methods from Collection.prototype

See Collection of node-mongodb-native for more information.
