Node basically builds server.js

const express = require('express');

const expressStatic = require('express-static');

const bodyparser = require('body-parser');

const multer = require ('multer');

const cookieParser = require('cookie-parser');

const cookieSession = require('cookie-session');

const consolidate = require('consolidate');

const mysql = require('mysql');

const expressRouter = require('express-route');

const multerObj = multer ({dest: './static/upload'});

const ejs = require('ejs')

const server = express();

server.listen(8080);

const mysql = require('mysql');

// connection pool

var db = mysql.createPool({

host: 'localhost',

user: 'root',

password: '123456',

database: 'learn'

})

// 1. Request data

// get comes with

server.use(multerObj.any());

server.use(bodyparser.urlencoded());

// 2.cookie

server.use(cookieParser());

(function(){

var keys = [];

for (var i = 0; i < 10000; i++) {

keys[i] = 'keys_' + Math.random()

}

server.use(cookieSession({

name: 'sess_id',

keys: keys,

maxAge: 20 * 60 * 1000

}))

})()

// 3. Template

server.engine('html',consolidate.ejs);

server.set('views','template');

server.set('view engine','html');

// 4.route

server.use('/', require('./route/web/web.js')());

server.use('/admin/', require('./route/admin/index.js')());

// 5.default:static

server.use(expressStatic('./static/'))
