4. Backend Development (Node.js/Express/MongoDB)

The backend is responsible for handling API requests, interacting with the MongoDB database, and serving data to the frontend.

4.1. Setup Instructions

1. Navigate to the server directory:

    cd pantherahive-notes/server

1. Install dependencies:

    npm install

1. Create a .env file in the server directory and add your MongoDB connection string and desired port:

    PORT=5000
    MONGO_URI=mongodb+srv://<username>:<password>@<cluster-url>/pantherahivenotes?retryWrites=true&w=majority

* Replace <username>, <password>, and <cluster-url> with your actual MongoDB Atlas (or local MongoDB) credentials.

1. Start the server:

    npm run dev

The server will run on http://localhost:5000 (or your specified port).

4.2. Backend Code

##### server/package.json

{
  "name": "pantherahive-notes-backend",
  "version": "1.0.0",
  "description": "Backend for PantheraHive Notes Application",
  "main": "server.js",
  "scripts": {
    "start": "node server.js",
    "dev": "nodemon server.js"
  },
  "keywords": [],
  "author": "PantheraHive",
  "license": "ISC",
  "dependencies": {
    "cors": "^2.8.5",
    "dotenv": "^16.4.5",
    "express": "^4.19.2",
    "mongoose": "^8.4.1"
  },
  "devDependencies": {
    "nodemon": "^3.1.3"
  }
}

##### server/.env

# Example .env file for backend
PORT=5000
MONGO_URI=mongodb+srv://your_username:your_password@your_cluster_url/pantherahivenotes?retryWrites=true&w=majority

• Explanation: This file stores sensitive configuration variables, keeping them out of source control. PORT defines where the Express server listens, and MONGO_URI is your MongoDB connection string.

##### server/server.js

require('dotenv').config(); // Load environment variables from .env file
const express = require('express');
const mongoose = require('mongoose');
const cors = require('cors'); // Import cors middleware
const noteRoutes = require('./routes/notes');

const app = express();
const PORT = process.env.PORT || 5000;
const MONGO_URI = process.env.MONGO_URI;

// Middleware
app.use(cors()); // Enable CORS for all routes
app.use(express.json()); // Parse JSON request bodies

// Logger middleware (optional, for development)
app.use((req, res, next) => {
    console.log(req.method, req.path, req.body);
    next();
});

// Routes
app.use('/api/notes', noteRoutes); // Mount note routes under /api/notes

// Database Connection
mongoose.connect(MONGO_URI)
    .then(() => {
        console.log('Connected to MongoDB Atlas');
        // Start the server only after successful database connection
        app.listen(PORT, () => {
            console.log(`Server running on port ${PORT}`);
        });
    })
    .catch((error) => {
        console.error('MongoDB connection error:', error);
        process.exit(1); // Exit process with failure
    });

// Basic error handling for unmatched routes
app.use((req, res) => {
    res.status(404).json({ message: 'API Endpoint Not Found' });
});

• Explanation: This is the main entry point for the backend. It sets up the Express application, connects to MongoDB using Mongoose, applies necessary middleware (CORS, JSON body parser), and mounts the API routes. The server only starts listening for requests once the database connection is established.

##### server/models/Note.js

const mongoose = require('mongoose');

const Schema = mongoose.Schema;

// Define the schema for a Note
const noteSchema = new Schema({
    title: {
        type: String,
        required: true,
        trim: true // Remove whitespace from both ends of a string
    },
    content: {
        type: String,
        required: true,
        trim: true
    }
}, { timestamps: true }); // Add createdAt and updatedAt timestamps automatically

// Create and export the Note model
module.exports = mongoose.model('Note', noteSchema);

• Explanation: This file defines the Mongoose schema for a Note. It specifies that each note must have a title and content, both of type String and required. timestamps: true automatically adds createdAt and updatedAt fields to each document.

##### server/routes/notes.js

const express = require('express');
const {
    createNote,
    getNotes,
    getNote,
    deleteNote,
    updateNote
} = require('../controllers/notesController');

const router = express.Router();

// GET all notes
router.get('/', getNotes);

// GET a single note
router.get('/:id', getNote);

// POST a new note
router.post('/', createNote);

// DELETE a note
router.delete('/:id', deleteNote);

// UPDATE a note
router.put('/:id', updateNote);

module.exports = router;

• Explanation: This file sets up the API endpoints for notes using Express Router. Each route (/, /:id) is mapped to a specific controller function that handles the logic for that operation (GET all, GET one, POST, DELETE, PUT).

##### server/controllers/notesController.js

const Note = require('../models/Note');
const mongoose = require('mongoose');

// GET all notes
const getNotes = async (req, res) => {
    try {
        const notes = await Note.find({}).sort({ createdAt: -1 }); // Sort by creation date, newest first
        res.status(200).json(notes);
    } catch (error) {
        res.status(500).json({ error: error.message });
    }
};

// GET a single note
const getNote = async (req, res) => {
    const { id } = req.params;

    // Validate if the ID is a valid MongoDB ObjectId
    if (!mongoose.Types.ObjectId.isValid(id)) {
        return res.status(404).json({ error: 'No such note found with that ID' });
    }

    try {
        const note = await Note.findById(id);

        if (!note) {
            return res.status(404).json({ error: 'No such note found' });
        }
        res.status(200).json(note);
    } catch (error) {
        res.status(500).json({ error: error.message });
    }
};

// CREATE a new note
const createNote = async (req, res) => {
    const { title, content } = req.body;

    // Basic validation
    if (!title || !content) {
        return res.status(400).json({ error: 'Please fill in all the fields (title and content)' });
    }

    try {
        const note = await Note.create({ title, content });
        res.status(201).json(note); // 201 Created
    } catch (error) {
        res.status(400).json({ error: error.message }); // 400 Bad Request for validation errors
    }
};

// DELETE a note
const deleteNote = async (req, res) => {
    const { id } = req.params;

    if (!mongoose.Types.ObjectId.isValid(id)) {
        return res.status(404).json({ error: 'No such note found with that ID' });
    }

    try {
        const note = await Note.findOneAndDelete({ _id: id });

        if (!note) {
            return res.status(404).json({ error: 'No such note found' });
        }
        res.status(200).json({ message: 'Note deleted successfully', note });
    } catch (error) {
        res.status(500).json({ error: error.message });
    }
};

// UPDATE a note
const updateNote = async (req, res) => {
    const { id } = req.params;

    if (!mongoose.Types.ObjectId.isValid(id)) {
        return res.status(404).json({ error: 'No such note found with that ID' });
    }

    try {
        const note = await Note.findOneAndUpdate({ _id: id }, { ...req.body }, { new: true }); // {new: true} returns the updated document

        if (!note) {
