node orm sequelize model-table 互相生成

经过比较个人感觉sequelize 比其他orm好用些，用了半天时间终于搞定了，直接上代码

1、利用sequelize    model生成table

applicationMysql.js文件－－－－－－－－－－－－

var Sequelize = require('sequelize');
var sequelize = new Sequelize('db', 'root', 'root', {
  host: 'localhost',
  dialect: 'mysql',
  pool: {
    max: 5,
    min: 0,
    idle: 10000
  },
  Sequelize :Sequelize
});

function ApplicationMysql(){
    return sequelize;
}
module.exports = new ApplicationMysql();

user.js文件－－－－－－－－－－－－－－－－－

var app = require('../server/applicationMysql.js');
User = app.define('user',{
  firstName: {
    type: app.Sequelize.STRING,
   // field: 'first_name' // Will result in an attribute that is firstName when user facing but first_name in the database
