安装mongodb

我觉得还是用mannual install靠谱一点儿：http://docs.mongodb.org/manual/tutorial/install-mongodb-on-os-x/

启动mongodb

$ mongod

连接mogodb

$ mongomongo> use monk-appmongo> db.products.insert({"name":"apple juice", "description":"good"})WriteResult({ "nInserted" : 1 })mongo> db.products.find().pretty(){  "_id" : ObjectId("53b4cf8d5ef358e649ff1665"),  "name" : "apple juce",  "description" : "good"}

在nodejs中用monk访问mongodb

$ mkdir monk-app$ cd monk-ap

创建package.json

{ "name": "monk-app", "version": "0.0.1", "private": true, "dependencies": {  "mongodb": "*",  "monk": "*" }}

$ npm install

创建app.js

链接前面创建的数据库

var monk = require('monk')var db = monk('localhost:27017/monk-demo')

读取数据：

var monk = require('monk')var db = monk('localhost:27017/monk-demo')var products = db.get('products')  products.find({}, function(err, docs) {   console.log(docs)})[ { _id: 53b4d3238cb4707ca35ab6f8,  name: 'apple juice',  description: 'good' } ]

插入数据：

products.insert({"name":"orange juice","description":"just so so"})

查找数据：

products.find({"name":"apple juice"}, function(err, docs) {  console.log(docs)})
