EN

const express = require('express');
const router = express.Router();

require('../db/conn');
const User = require('../model/userSchema');

router.get('/', (req, res) => {
    res.send(`Hello World from the server from router.`);
});

router.post('/register', (req, res) => {
    
    const { name,email,phone,work,password,cpassword } = req.body;
    
    if(!name || !email || !phone || !work || !password || !cpassword){
        return res.status(422).json({error:"please fill all the fields data.."});
    }
    User.findOne({ "$or": [ { email: email }, { phone: phone} ] })
    .then((userExist) => {
        if(userExist){
            return res.status(422).json({error:"Email ID or Mobile No is already exist."});
        }

            const user = new User({name,email,phone,work,password,cpassword});
            
            user.save().then(() => {
                res.status(201).json({message:"User Registered Successfully."});
            }).catch((err) => res.status(500).json({error:"Failed to regsiter user."}));
    }).catch(err => { console.log(err)});
});
module.exports = router;

await User.findOne({ "$or": [ { email: email }, { phone: phone} ] });
