Login Registration Form Using Node js React

In this video tutorials explains how to make the user login and Registration Form using Node js React, Express js,MongoDB.using MVC architecture. we have created routes,studentControler,studentServices,studentModel.

First you have to Create the Project

npm init

const express = require('express')
const app = express()
const mongoose = require('mongoose');
mongoose.set('strictQuery', false);
var routes = require('./route/routes');
const cors = require('cors');

app.use(cors(
  {
    origin: "http://localhost:3000"
  }

));

app.listen(9992,function check(err)
{
    if(err)
    console.log("error")
    else
    console.log("started")
});

mongoose.connect("mongodb://localhost:27017/gbs",{useNewUrlParser: true,  useUnifiedTopology: true },
function checkDb(error)
{
    if(error)
    {
        console.log("Error Connecting to DB");
    }
    else
    {
        console.log("successfully Connected to DB");
    }
});
app.use(express.json());
app.use(routes);

var express = require('express');

var studentController = require('../src/student/studentController');
const router = express.Router();

router.route('/student/login').post(studentController.loginUserControllerFn);
router.route('/student/create').post(studentController.createStudentControllerFn);


module.exports = router;

var studentService = require('./studentService');

var createStudentControllerFn = async (req, res) => 
{
    try
    {
    console.log(req.body);
    var status = await studentService.createStudentDBService(req.body);
    console.log(status);

    if (status) {
        res.send({ "status": true, "message": "Student created successfully" });
    } else {
        res.send({ "status": false, "message": "Error creating user" });
    }
}
catch(err)
{
    console.log(err);
}
}

var loginUserControllerFn = async (req, res) => {
    var result = null;
    try {
        result = await studentService.loginuserDBService(req.body);
        if (result.status) {
            res.send({ "status": true, "message": result.msg });
        } else {
            res.send({ "status": false, "message": result.msg });
        }

    } catch (error) {
        console.log(error);
        res.send({ "status": false, "message": error.msg });
    }
}

module.exports = { createStudentControllerFn,loginUserControllerFn };

var studentModel = require('./studentModel');
var key = '123456789trytryrtyr';
var encryptor = require('simple-encryptor')(key);

module.exports.createStudentDBService = (studentDetails) => {


   return new Promise(function myFn(resolve, reject) {

       var studentModelData = new studentModel();

       studentModelData.firstname = studentDetails.firstname;
       studentModelData.lastname = studentDetails.lastname;
       studentModelData.email = studentDetails.email;
       studentModelData.password = studentDetails.password;
       var encrypted = encryptor.encrypt(studentDetails.password);
       studentModelData.password = encrypted;

       studentModelData.save(function resultHandle(error, result) {

           if (error) {
               reject(false);
           } else {
               resolve(true);
           }
       });

   });

}

module.exports.loginuserDBService = (studentDetails)=> 
{
   return new Promise(function myFn(resolve, reject) 
   {
      studentModel.findOne({ email: studentDetails.email},function getresult(errorvalue, result)
      {
         if(errorvalue)
         {
            reject({status: false, msg: "Invaild Data"});
         }
         else
         {
            if(result !=undefined &&  result !=null)
            {
               var decrypted = encryptor.decrypt(result.password);

               if(decrypted== studentDetails.password)
               {
                  resolve({status: true,msg: "Student Validated Successfully"});
               }
               else
               {
                  reject({status: false,msg: "Student Validated failed"});
               }
            }
            else
            {
               reject({status: false,msg: "Student Error Detailssss"});
            }

         }
      
      });
      
   });
}

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

var studentSchema = new Schema({

    firstname: {
        type: String,
        required: true
    },
    lastname: {
        type: String,
        required: true
    },
    email: {
        type: String,
        required: true
    },
    password: {
        type: String,
        required: true
    }

});

module.exports = mongoose.model('student', studentSchema);

React

React is a front-end application we have already created the folder front end inside the folder open the command prompt and type the commands.

Installing React

npx create-react-app front-end

After that you need to install the required dependencies

1. npm i axios

For managing the Api requests

2.npm i react-router-dom

For managing the routes

After that go to the bootstrap webite and copy the bootstap css style and paste inside the

index.html  inside the head tag.

After install open the project into Vscode Editor.create the folder inside src which name is components inside the folder create 3 files. Home.jsx,Register.jsx,Login.jsx

Register.jsx

import axios from "axios";
import {  useState } from "react";


function Register() {

    const [fname, setFName] = useState("");
    const [lname, setLName] = useState("");

    const [email, setEmail] = useState("");
    const [password, setPassword] = useState("");


    async function save(event) {
        event.preventDefault();
        try {
          await axios.post("http://localhost:9992/student/create", {
          firstname: fname,
          lastname: lname,
          email: email,
          password: password,
          });
          alert("Student Registation Successfully");

        } catch (err) {
          alert(err);

function Home() {
    return (
     <div>
        <h1>index</h1>
     </div>

  }
  
  export default Home;

Configure the Routes

open the App.js

App.js

import { BrowserRouter,Routes,Route } from "react-router-dom";

import UserRegistation from "./components/UserRegistation";
import Login from "./components/Login";

import Home from "./components/Home";

function App() {
  return (
   <div>
        <BrowserRouter>
            <Routes>
              <Route path="/home" element= { <Home/>} />
              <Route path="/register" element= { <UserRegistation/>} />
              <Route path="/" element= { <Login/>} />
            </Routes>
        </BrowserRouter>
   </div>
  );
}

export default App;
