Connecting the server to MongoDB

To connect your Node server to MongoDB, add the following code to server.js, and make sure you have MongoDB running in your workspace.

mern-simplesetup/server/server.js:

import { MongoClient } from 'mongodb'
const url = process.env.MONGODB_URI || 'mongodb://localhost:27017/mernSimpleSetup'
MongoClient.connect(url, (err, db)=>{
  console.log("Connected successfully to mongodb server")
  db.close()
})

In this code example, MongoClient is the driver that connects to the running MongoDB instance using its url and allows us to implement the database related code in the backend.
