User create using NodeJS

Objective: In this article, you will know mongoose model, how to create user using node, router.

Pre-requisite Prior to completing this article, you should have already installed all pre-requisite tooling including: Visual Studio Code, Node Package Manager (NPM), Node, Postman, Mongo Compass.

Create a Model (ProfileModel.js)

const mongoose = require('mongoose')

const DataSchema = mongoose.Schema({
    FirstName : {type: String},
    LastName : {type: String},
    EmailAddress : {type: String},
    MobileNumber : {type: String},
    City : {type: String},
    UserName : {type: String},
    Password : {type: String}
});

const ProfileModel = mongoose.model('Profile', DataSchema)
module.exports = ProfileModel;

Create a Controller (ProfileController.js)

At first import ProfileModel. Declare a variable reqBody to store body data. Then create user using ProfileModel model

const ProfileModel = require("../models/ProfileModel");


exports.CreateProfile = (req, res) => {

    let reqBody = req.body;
    ProfileModel.create(reqBody, (err, data) => {
        if(err){
            res.status(400).json({status: "Failed to user create", data: err})
        }else{
            res.status(200).json({status: "Successfully user created", data: data})
        }
    })
}

Default configuration (app.js)

// Basic import
const express = require('express');
const router = require('./src/routes/api')
const app = new express();
const bodyParser = require('body-parser')

// Database lib import
const mongoose = require('mongoose')

// Body parser implement
app.use(bodyParser.json())

// MongoDB database connection
let uri = 'mongodb://127.0.0.1:27017/PracticeDB'
let options = {user: '', pass: ''}
mongoose.connect(uri, options, (err) => {
    if(err){
        console.log(err)
    }else{
        console.log('Database Connection Success')
    }
})

// Routing Implement
app.use('/api/v1', router)

// Undefined Route Implement
app.use("*", (req, res) => {
    res.status(404).json({status: "Failed", data: "Not Found"})
})

module.exports = app;

Routes configuration (api.js)

const express = require('express');
const ProfileController = require('../controller/ProfileController')
const router = express.Router();

router.post('/CreateProfile', ProfileController.CreateProfile)

module.exports = router;

Index file (index.js)

const app = require('./app')

app.listen(5000, function(){
    console.log('Server run at @5000 port')
})

Now open the Postman and configure few thing like

Then create a user giving basic information and click Send Button

Let's see into Database
