Accessing the MongoDB database via Node.js

We are now going to create a new web server that, instead of returning users from a JSON file, returns the list of users from our previously created users collection:

1. In the ch2 folder, open a Terminal. Install the mongodb package, which contains the official MongoDB driver for Node.js:

   $ npm install [email protected]

2. Create a new backend/mongodbweb.js file and open it. Import the following:

   import { createServer } from 'node:http'
   import { MongoClient } from 'mongodb'

3. Define the connection URL and database name and then create a new MongoDB client:

   const url = 'mongodb://localhost:27017/'
   const dbName = 'ch2'
   const client = new MongoClient(url)

4. Connect to the database and log a message after we are connected successfully, or when there is an error with the connection:

   try {
     await client.connect()
     console.log('Successfully connected to database!')
