Define router.post(“/”) in index.js file

Copy and paste the below code in index.js file of routes folder.


const mongoose = require('mongoose');
mongoose.connect('mongodb://localhost:27017/employee', {useNewUrlParser: true});
var conn =mongoose.Collection;

var employeeSchema =new mongoose.Schema({
	name: String,
