前言
纯前端开发，零后端基础，记录第一次搭建服务器
准备
- node + express 4.x
- MongoDB 3.4 + mongoose 4.10.8
安装nodejs、mongodb
https://nodejs.org/en/
https://www.mongodb.com/download-center
配置 MongoDB
配置成window服务，添加目录
-config //配置文件目录
-mongodb.cfg
-db //数据目录
-log //日志目录
mongodb.cfg
systemLog: //日志配置
destination: file //日志输出目的地，可以指定为“ file”或者“syslog”
path: D:\MongoDB\data\log\mongod.log
logAppend: true //当mongod/mongos重启后是否在现有日志文件添加日志
storage:
journal:
enabled: true //是否开启journal日志持久存储
dbPath: D:\MongoDB\data\db
net:
port: 27017 //mongod/mongos侦听端口，默认为27017
安装服务
cd 到 D:\MongoDB\Server\3.4\bin
D:\MongoDB\Server\3.4\bin> ./mongod.exe --config "D:\MongoDB\data\config\mongod.cfg" --install
启动mongodb服务
net start MongoDB
新建工程
- yarn add express //安装express
- cd到指定的目录 //更改路径
- express -e xxx //创建工程，e为ejs模版，xxx为文件夹名
安装必要插件，packge.json 如下
{
"name": "server",
"version": "0.0.0",
"private": true,
"scripts": {
"start": "node ./bin/www"
},
"dependencies": {
"body-parser": "^1.17.2",
"debug": "^2.6.8",
"ejs": "^2.5.6",
"express": "^4.15.3",
"file-stream-rotator": "^0.1.0",
"mongoose": "4.10.8",
"morgan": "^1.8.2",
"serve-favicon": "^2.4.3"
}
}
文件目录
-bin
-config //配置文件
-mongoose.js
-logs //生成日志文件
-models
-public //静态资源
-routes //路由模块
-index.js
-utils //自定义中间件
-views //模版文件夹
-index.html
-app.js //入口文件
-package.json

// 生成日志文件
app.use(logger('combined', {stream: accessLogStream}))

config/mongoose.js

console.log(err);
} else {

routes/index.js
var express = require('express');
var router = express.Router();
/* GET home page. */
router.get('/', function(req, res, next) {
res.render('index', { title: 'Express' });

var router = express.Router();
/* GET home page. */

启动服务器
node ./bin/www
在浏览器中输入 http://localhost:3000/index
