Package output in your project

Model

models/userModel.js :

const mongoose = require('mongoose');
const Schema   = mongoose.Schema;

const userSchema = new Schema({
	'firstName' : String,
	'lastName' : String,
	'email' : String,
	'password' : String,

/*

With files tree generation by module

Files tree generation grouped by Type or by Module (t/m) ? [t] : m
        create: ./user
        create: ./user/userModel.js
        create: ./user/userController.js
        create: ./user/userRoutes.js

You then only have to add router in app.js file and MongoDB connection whit Mongoose. app.js :

const routes = require('./src/routes/index');
const users = require('./src/routes/userRoutes');
 ...

app.use('/', routes);
app.use('/users', users);
 ...
