basically i have two folder in the root...the structure in like this in the root

models |----User.js routes |----api |----users.js 1.The code under User.js is:-

const mongoose = require('mongoose'); const Schema = mongoose.Schema; //create schema const UserSchema = new Schema({ name: { type: String, required: true }, email: { type: String, required: true }, password: { type: String, required: true }, avatar: { type: String }, date: { type: Date, default: Date.now },

}); module.exports = User = mongoose.model('user', UserSchema); 2.The code under users.js const express = require('express'); const router = express.Router(); const gravatar = require('gravatar'); const bcrypt = require('bcryptjs'); //load user model const User = require('../../models/User'); router.get('/test', (req, res) => res.json({msg: 'user works'})); //route Get api/user/register router.post('/register',(req,res) =>{ User.findOne({email : req.body.email}) .then(user =>{ if(user){ return res.status(400).json({email:'Email already exist'}); }else{ const avatar =gravatar.url(req.body.email,{ s:'200', r:'pg', d:'mm' } ); const User = new User({ name:req.body.name, email:req.body.email, avatar, password:req.body.password

  });
  bcrypt.genSalt(10,(err, salt)=>{
    bcrypt.hash(newUser.password,salt,(err,hash) =>{
      if(err) throw err;
      newUser.password = hash;
      newUser.save()
      .then(user => res.json(user))
      .catch(err => console.log(err));
    }

    )
  }
)
}

}) });

module.exports = router; 3.postman is giving the suitable output on htttp://localhost:5000/api/users/test but not giving the output for http://localhost:5000/api/users/register now it is showing the error:-
