model은 스키마를 감싸주는 역활

const mongoose = require('mongoose')

const userSchema = mongoose.Schema({

name:{

type : String,

maxlength: 50

},

email:{

type: String,

trim : true,

unique: 1

},

lastname : {

type : String,

maxlength: 50

},

role : {

type : Number,

default : 0

},

image : String,

token : {

type : String

},

tokenExp : {

type : Number

}

})

const User = mongoose.model('User',userSchema) //모델의 이름적용 스키마를 감싸줌

module.exports = {User}//다른파일에서도 사용할 수 있게 

email type 이메일 내에 빈칸 공백 없애준다.

unique 값을 1로 설정 하나의 이메일로만 사용

role의 역활 관리자와 일반유저 나누기 위해서

ex 1이면 관리자 0이면 일반 유저 

token 사용기간 만료 설정
