This tutorial will teach you how to make Crud Application using Node JS with Vue Js Frontend application and Mongo DB Database using Api access Crudapplication.

First Step What you have to do is you to divide the Front-End and Back-End.

Front-End – Vue JS

BackEnd – Node JS

Create the folder myprojects. inside the folder Frond end project you maintaining with the separate folder.
Backend project you maintaining with the separate folder.

Install Node JS

Create a new Project type the command on the command prompt.

Type the Command on Console.

npm init

npm init

and create your project. After project has been created you see the package.json file.

Then open the project in to the VS Code Editor by typing the following command

code .

code .

after open up the project in to the vscode editor

Install the Express Server as back end server

npm i express

1	npm i express

Install the mongoDB as database

npm i express

1	npm i express

First Create the Application server.js which manage the ports and libraries and database connection of the project.

we have created the datbase on mongoDB Compass which name est.
attached the db connection below.

server.js

var express = require('express');
var server = express();
var routes = require('./routes/routes');
var mongoose = require('mongoose');
const cors = require('cors');
mongoose.connect("mongodb://localhost:27017/est",{useNewUrlParser: true,  useUnifiedTopology: true },function checkDB(error)
{
    if(error)
    {
        console.log("errorr")
    }
    else
    {
        console.log("DB Connectedddd!!!!!!!!!!!")
    }
});

server.use(cors());
server.use(express.json());
server.use(routes);

server.listen(8000,function check(error)
{
    if(error)
    {
        console.log("errorr")
    }
    else
    {
        console.log("startedddddd")
    }
});

var express = require('express');

var server = express();

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

var mongoose = require('mongoose');

const cors = require('cors');

mongoose.connect("mongodb://localhost:27017/est",{useNewUrlParser: true, useUnifiedTopology: true },function checkDB(error)

{

if(error)

{

console.log("errorr")

}

else

{

console.log("DB Connectedddd!!!!!!!!!!!")

}

});

server.use(cors());

server.use(express.json());

server.use(routes);

server.listen(8000,function check(error)

{

if(error)

{

console.log("errorr")

}

else

{

console.log("startedddddd")

}

});

After that you can run the server type by the following command.

node server.js

1	node server.js

You can get the result as

DB Connectedddd
startedddddd

after that make the new folder route and inside the folder create the page route.js. route.js page which use to manage the all the restapis related to crud operations.

var express = require('express');

const router = express.Router();

var userController = require('../src/user/userController');

router.route('/user/getAll').get(userController.getDataConntrollerfn);

router.route('/user/create').post(userController.createUserControllerFn);

router.route('/user/update/:id').patch(userController.updateUserController);

router.route('/user/delete/:id').delete(userController.deleteUserController);

module.exports = router;

var express = require('express');

const router = express.Router();

var userController = require('../src/user/userController');

router.route('/user/getAll').get(userController.getDataConntrollerfn);

router.route('/user/create').post(userController.createUserControllerFn);

router.route('/user/update/:id').patch(userController.updateUserController);

router.route('/user/delete/:id').delete(userController.deleteUserController);

module.exports = router;

After that create the MVC Page.First Create the Controller Page

userController.js

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

var getDataConntrollerfn = async (req, res) =>
{
    var empolyee = await userService.getDataFromDBService();
    res.send({ "status": true, "data": empolyee });
}

var createUserControllerFn = async (req, res) => 
{
    var status = await userService.createUserDBService(req.body);
    if (status) {
        res.send({ "status": true, "message": "User created successfully" });
    } else {
        res.send({ "status": false, "message": "Error creating user" });
    }
}

var updateUserController = async (req, res) => 
{
    console.log(req.params.id);
    console.log(req.body);
     
    var result = await userService.updateUserDBService(req.params.id,req.body);

     if (result) {
        res.send({ "status": true, "message": "User Updateeeedddddd"} );
     } else {
         res.send({ "status": false, "message": "User Updateeeedddddd Faileddddddd" });
     }
}

var deleteUserController = async (req, res) => 
{
     console.log(req.params.id);
     var result = await userService.removeUserDBService(req.params.id);
     if (result) {
        res.send({ "status": true, "message": "User Deleteddd"} );
     } else {
         res.send({ "status": false, "message": "User Deleteddd Faileddddddd" });
     }
}
module.exports = { getDataConntrollerfn, createUserControllerFn,updateUserController,deleteUserController };

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

var getDataConntrollerfn = async (req, res) =>

{

var empolyee = await userService.getDataFromDBService();

res.send({ "status": true, "data": empolyee });

}

var createUserControllerFn = async (req, res) =>

{

var status = await userService.createUserDBService(req.body);

if (status) {

res.send({ "status": true, "message": "User created successfully" });

} else {

res.send({ "status": false, "message": "Error creating user" });

}

var updateUserController = async (req, res) =>

{

console.log(req.params.id);

console.log(req.body);

var result = await userService.updateUserDBService(req.params.id,req.body);

if (result) {

res.send({ "status": true, "message": "User Updateeeedddddd"} );

} else {

res.send({ "status": false, "message": "User Updateeeedddddd Faileddddddd" });

}

var deleteUserController = async (req, res) =>

{

console.log(req.params.id);

var result = await userService.removeUserDBService(req.params.id);

if (result) {

res.send({ "status": true, "message": "User Deleteddd"} );

} else {

res.send({ "status": false, "message": "User Deleteddd Faileddddddd" });

}

module.exports = { getDataConntrollerfn, createUserControllerFn,updateUserController,deleteUserController };

Vue.js

Install Vue.js CLI

npm install -g vue-cli

1	npm install -g vue-cli

After installed successfully create the vue.js project using following command

vue init webpack frontend

1	vue init webpack frontend

After installation completed open the project in to vs code editor

First Step

Create the component Employeecrud.vue.

EmployeeCrud.vue
