創(chuàng)建項(xiàng)目目錄并安裝mongodb、mongoose

[root@localhost html]#  mkdir test
[root@localhost html]#  cd test
//安裝mongodb
[root@localhost test]# npm install mongodb
//安裝mongoose庫
[root@localhost test]# npm install mongoose

mongoose插入數(shù)據(jù)

//引入mongoose組建
var mongoose = require('mongoose');
//連接mongoose,并選擇數(shù)據(jù)庫
var db = new     mongoose.createConnection('mongodb://192.168.1.203:27017/shop');
//創(chuàng)建模型
var monSchema = new mongoose.Schema({
 sname:{type:String}, //商品名稱
 sprice:{type:Number}, //商品價(jià)格
 stock:{type:Number}, //庫存
 sinfo:{type:String}, //商品介紹 
 addtime:{type:Number} //添加時(shí)間
});
//數(shù)據(jù)表
var monModel = db.model('goods',monSchema);

//商品內(nèi)容信息
var content = {
 sname:'聯(lián)想筆記本',
 sprice:5908,
 stock:100,
 addtime:Date.new(),
 sinfo:'很不錯(cuò)的筆記本，值得購買'

//把商品內(nèi)容信息寫入數(shù)據(jù)庫
var monInsert = new monModel(content);

monInsert.save(function(err){
 if(err){
 console.log(err);
 }else{
 console.log('商品數(shù)據(jù)寫入成功');

mongoose查詢數(shù)據(jù)

mongoose修改數(shù)據(jù)

//引入mongoose組建

mongoose刪除數(shù)據(jù)

//引入mongoose組建
var mongoose = require('mongoose');

//連接mongoose,并選擇數(shù)據(jù)庫
