Let's break down how to create a Node.js project, set up a MongoDB database, and connect the two.


Create a new folder on your computer where you'll keep your project (for example, `my-mongo db-project`).
Open your terminal or command prompt and navigate to this newly created folder.


Run the following command to initialize a new Node.js project:
npm init -y


This creates a `package.json` file, which will manage your project's dependencies.

Install the required `mongo db` package to interact with Mongo DB from Node.js:
npm install mongo db


Create a MongoDB Atlas Account: Go to https://www.mongodb.com/cloud/atlas and sign up for a free account.
Create a Cluster: Follow the steps in the Atlas dashboard to deploy a new cluster. Choose the Free Tier option to start without costs.
Connection Settings: Retrieve your connection string from the Atlas dashboard after setting up a database user.


Connecting Your Node.js Project to Mongo DB

Create a JavaScript File: Inside your project folder, create a JavaScript file (for example, `app.js`).

Add the Connection Code: Paste the following code into `app.js`, and make sure to replace the `your connection string` placeholder with your actual MongoDB connection string (from Atlas or your local setup):


Run Your Project: In your terminal, execute your script:
node app.js


If successful, you should see a message in the console indicating that you've established a connection with your MongoDB database.
