Hey it’s my node js code :slightly_smiling_face:

</>
const express= require(‘express’);
const mongoose = require(‘mongoose’);
const app = express();
const mongoDB = “mongodb://localhost:27017/ecomm”;

mongoose.connect(mongoDB,{ useNewUrlParser: true })
.then(()=>console.log(‘connection successfully’))

app.listen(5000,()=>{
console.log(‘Server is running on port : 5000’);
})

</>
