hacken/User/controller.js

Hacken is a node module to help people in hackathons, it has almost all the common features a person needs from database operations to sockets. If you are the one who struglles with MongoDb ObjectId, hacken makes it easier to work with then too.

const model = require('./userModel.js');
const roomModel = require('./../sockets/roomModel.js');
const {isObjValid} = require('./../objectop.js');
const mongoose = require('mongoose');
