Updates To Index.js

Now that you have a database.js file with a connectToDb function, we need to update index.js so it stops using the JSON file and starts talking to MongoDB instead. We will keep this as simple as possible and only change what is needed.

You need to

• Import connectToDb from database.js

• Remove the JSON file code

• Update the POST /contact route to save to MongoDB

• Update the GET /messages route to read from MongoDB

Import the database helper

At the top of index.js, you probably have something like this:

const express = require("express");
const fs = require("fs");

We no longer need fs, and we want to import the connectToDb function we made from the database.js file. Change the top of index.js to this to import the function:

const express = require("express");
const { connectToDb } = require("./database");
