This tutorial will teach you how to make a Registration Login form Application using Node JS and MongoDB using MVC architecture. we have created routes,userControler,userServices,useModel.
First you have to Create the Project
1 | npm init |
After run the command package.json file has been created.
First Step Create the page which is server.js which use to connect the port and databases.
server.js
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 | const express = require('express') const app = express(); const mongoose = require('mongoose'); var routes = require('./routes/routes'); mongoose.set('strictQuery', false); 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.listen(9002,function check(error) { if(error) console.log("Error....!!!!"); else console.log("Started....!!!!"); }); app.use(express.json()); app.use(routes); |
routes.js
1 2 3 4 5 6 7 8 9 10 | var express = require('express'); var userController = require('../src/user/userController'); const router = express.Router(); router.route('/user/login').post(userController.loginUserControllerFn); router.route('/user/create').post(userController.createUserControllerFn); module.exports = router; |
userControler.js

userServices.js

userModel.js
