MEAN stack crud tutorial code example

Example 1: crud application in mean stack

// MongoDB Databse url
var mongoDatabase = 'mongodb://localhost:27017/employeeDetails';

// Connect Mongodb Database
mongoose.connect(mongoDatabase, { useNewUrlParser: true }).then(
 () => { console.log('Database is connected') },
 err => { console.log('There is problem while connecting database ' + err) }

Example 2: crud application in mean stack

// Imported required packages
const express = require('express'),
 path = require('path'),
 bodyParser = require('body-parser'),
 cors = require('cors'),
 mongoose = require('mongoose');

// MongoDB Databse url
var mongoDatabase = 'mongodb://localhost:27017/employeeDetails';

// Created express server
const app = express();
mongoose.Promise = global.Promise;

// Connect Mongodb Database
mongoose.connect(mongoDatabase, { useNewUrlParser: true }).then(
 () => { console.log('Database is connected') },
 err => { console.log('There is problem while connecting database ' + err) }
);

// All the express routes
const employeeRoutes = require('../Routes/Employee.route');

// Conver incoming data to JSON format
app.use(bodyParser.json());

// Enabled CORS
app.use(cors());

// Setup for the server port number
const port = process.env.PORT || 4000;

// Routes Configuration
app.use('/employees', employeeRoutes);

// Staring our express server
const server = app.listen(port, function () {
 console.log('Server Lisening On Port : ' + port);
});
