MERN_PROJECT_BMSCE

This repository gives you a simple and clean starting point to create a full-stack MERN application (MongoDB, Express, React, Node.js).

---

Prerequisites

Make sure you have installed on your system:

• Node.js (LTS version recommended)
• npm (comes with Node.js)
• MongoDB Atlas account (or a MongoDB cluster URI)

---

How to Run the MERN App

All commands below are run from a terminal in the project root folder MERN_PROJECT_BMSCE.

1. Start the React Client

cd my_first_mern_app
cd client
npm install
npm run dev

Then open the localhost link shown in the terminal (Vite dev server URL).

2. Start the Node/Express Server

Open a new terminal (or tab) and from the project root run:

cd my_first_mern_app
cd server
npm install

Now configure your MongoDB connection:

1. Open my_first_mern_app/server/index.js.
2. Find the line with:

   mongoose.connect(

3. Paste your MongoDB cluster connection string (URI) there.
4. Append the query parameter appName=Cluster0 if required by your setup.

Finally, start the server:

node index.js

• The backend will listen on http://localhost:3001 (as used in the React app).
• The React frontend (Vite) runs on another port (usually 5173 by default).
