How to create Model from schema with Mongoose? Uncaught TypeError: User.create is not a function

I am trying to run the code from J. Wexler's book. The book is available at GitHub.

Now, I am working on 18_1,chapter 4.

I have followed all the steps in book to create User in REPL.

const User = require
("./models/user")

user.js

"use strict";

const mongoose = require("mongoose"),
  { Schema } = mongoose,
  userSchema = new Schema(
    {
      name: {
        first: {
          type: String,
          trim: true
        },
        last: {
          type: String,
          trim: true
        }
      },
      email: {
        type: String,
        required: true,
        lowercase: true,
        unique: true
      },
      zipCode: {
        type: Number,
        min: [1000, "Zip code too short"],
        max: 99999
      },
      password: {
        type: String,
        required: true
      },
      courses: [{ type: Schema.Types.ObjectId, ref: "Course" }],
      subscribedAccount: {
        type: Schema.Types.ObjectId,
        ref: "Subscriber"
      }
    },
    {
      timestamps: true
    }
  );

userSchema.virtual("fullName").get(function() {
  return `${this.name.first} ${this.name.last}`;
});
module.exports = mongoose.model("User", userSchema);

The last line exports mongoose.model

Anyway

User.create({name: { first: "John" ,last : "Walker"}, email: "[email protected]", password : "piha111"}).
... then(user => firstUser = user).
... catch(error => console.log(error.message));

leads to this error

Uncaught TypeError: User.create is not a function

Althouglh Node repl,sees User as a Function

<pre>&gt; User
<font color="#555753">{ [Function: require] resolve: { [Function: resolve] paths: [Function: paths] }, main: undefined, extensions: [Object: null prototype] { &apos;.js&apos;: [Function (anonymous)], &apos;.json&apos;: [Function (anonymous)],</font></pre> 

> typeof(User)
'function'

Since you are using REPL

The following will get evaluated as 2 separate statements

const User = require
("./models/user")

This will assign the function require to variable User and just evaluate the string "./models/user"

What you supposed to do is calling require('./models.user') and assign it to the User variable. It should be like this

const User = require('./models/user')

Note that this behaviour will not occur if you put the same code in a javascript file and execute it. Because the whole file will be parsed at the same time, not line by line like in REPL

instead of

User.create({name: { first: "John" ,last : "Walker"}, email: "[email protected]", password : "piha111"}).
... then(user => firstUser = user).
... catch(error => console.log(error.message));

try this one

let newUser =new User({name: { first: "John" ,last : "Walker"}, email: "[email protected]", password : "piha111"});
newUser.save((err,usr)=>{ 
                    if(err) 
                        return err; 
                    firstUser = usr })
