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
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 .
after open up the project in to the vscode editor
Install the Express Server as back end server
npm i express
Install the mongoDB as database
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")
}
});
After that you can run the server type by the following command.
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;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 };
userService.js
var userModel = require('./userModel');
module.exports.getDataFromDBService = () => {
return new Promise(function checkURL(resolve, reject) {
userModel.find({}, function returnData(error, result) {
if (error) {
reject(false);
} else {
resolve(result);
}
});
});
}
module.exports.createUserDBService = (userDetails) => {
return new Promise(function myFn(resolve, reject) {
var userModelData = new userModel();
userModelData.name = userDetails.name;
userModelData.address = userDetails.address;
userModelData.phone = userDetails.phone;
userModelData.save(function resultHandle(error, result) {
if (error) {
reject(false);
} else {
resolve(true);
}
});
});
}
module.exports.updateUserDBService = (id,userDetails) => {
console.log(userDetails);
return new Promise(function myFn(resolve, reject) {
userModel.findByIdAndUpdate(id,userDetails, function returnData(error, result) {
if(error)
{
reject(false);
}
else
{
resolve(result);
}
});
});
}
module.exports.removeUserDBService = (id) => {
return new Promise(function myFn(resolve, reject) {
userModel.findByIdAndDelete(id, function returnData(error, result) {
if(error)
{
reject(false);
}
else
{
resolve(result);
}
});
});
}
userModel.js
var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var userSchema = new Schema({
name: {
type: String,
required: true
},
address: {
type: String,
required: true
},
phone: {
type: String,
required: true
}
});
module.exports = mongoose.model('employees', userSchema);Vue.js
Install Vue.js CLI
npm install -g vue-cli
After installed successfully create the vue.js project using following command
vue init webpack frontend
After installation completed open the project in to vs code editor
First Step
Create the component Employeecrud.vue.
EmployeeCrud.vue
<template>
<div>
<h2>Employee Registation</h2>
<form @submit.prevent="save">
<div class="form-group">
<label>Employee name</label>
<input type="text" v-model="employee.name" class="form-control" placeholder="Employee name">
</div>
<div class="form-group">
<label>Employee Address</label>
<input type="text" v-model="employee.address" class="form-control" placeholder="Employee Address">
</div>
<div class="form-group">
<label>Mobile</label>
<input type="text" v-model="employee.phone" class="form-control" placeholder="Mobile">
</div>
<button type="submit" class="btn btn-primary">Save</button>
</form>
<h2>Employee View</h2>
<table class="table table-dark">
<thead>
<tr>
<th scope="col">ID</th>
<th scope="col">Employee Name</th>
<th scope="col">Address</th>

<tbody>
<tr v-for="employee in result" v-bind:key="employee._id">

</tr>
</tbody>
</table>
</div>
</template>

import Vue from 'vue';
import axios from 'axios';
Vue.use(axios)
export default {

remove(employee){
var url = `http://localhost:8000/user/delete/${employee._id}`;
axios.delete(url);

import Vue from 'vue'
import Router from 'vue-router'
import EmployeeCrud from '@/components/EmployeeCrud'
Vue.use(Router)
export default new Router({
routes: [
{
path: '/',
