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
$ mongo mongo> use monk-app mongo> 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) })
