Auth

this is used for errors validation with mongodb and others.

1. Errordisplay is a function that validates ur mongoose validator and some errors for you by parsing the error to Errordisplay function and it returns msg and logs out the error

2. SessionAuth is an Auth system for Authenticatio, you parse these to the SessionAuth function

    ID: This is to check for the Id in sessionDB
    userID: to create new sessionId and eliminate the rest. e.g SessionAuth(null,theId)
   

It returns either

    {
            NoAccess:false/true, // this is parsed when ID is parsed
            user // this is parsed when ID is parsed
            Auth //This is passed when creating new session
            error:Error/null
    }

3. Create Session DB

       const mongoose = require('mongoose');
   
    const Schema = mongoose.Schema
   
    // create this dm
    const SessionModel = new Schema({
        //major user id will be pared here
        UserId:{
    type:String,
    required:[true, "UserID is Required"],
    unique:true
        },
   
        //when data expires
        expireAt:{
    type:Date,
    default:new Date(new Date().getTime()+2880*60000),
    // expires:'40320m'
        },
   
    },{timestamps:true})
   
    module.exports = mongoose.model('SessionModel', SessionModel)
