mongodb
安裝mongodb
我認為還是用mannual install靠譜一點兒:http://docs.mongodb.org/manual/tutorial/install-mongodb-on-os-x/
啟動mongodb
$ mongod
串連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訪問mongodb
$ mkdir monk-app
$ cd monk-ap
建立package.json
{
"name": "monk-app",
"version": "0.0.1",
"private": true,
"dependencies": {
"mongodb": "*",
"monk": "*"
}
}
$ npm install
建立app.js
連結前面建立的資料庫
var monk = require(‘monk‘)
var db = monk(‘localhost:27017/monk-demo‘)
讀取資料:
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‘ } ]
插入資料:
products.insert({"name":"orange juice","description":"just so so"})
尋找資料:
products.find({"name":"apple juice"}, function(err, docs) {
console.log(docs)
})
在mongodb建立自增id:
