Library Management System in MERN Stack project Front-End Back-End

Creating a complete Library Management System using the MERN (MongoDB, Express.js, React, Node.js) stack involves a considerable amount of code. Below, I’ll provide you with a simplified example of the folder structure, key components, and code snippets for both the front end and back end. Keep in mind that this example is a starting point, and you’ll need to expand upon it to create a fully functional system.

Backend Implementation (Express.js, MongoDB, Passport.js)

  1. server.js – Express server setup and configuration:
const express = require('express');
const mongoose = require('mongoose');
const bodyParser = require('body-parser');
const passport = require('passport');
const cors = require('cors');
const apiRoutes = require('./routes/api');
const config = require('./config/config');

const app = express();

app.use(cors());
app.use(bodyParser.json());
app.use(passport.initialize());
require('./config/passport')(passport);

mongoose.connect(config.mongoURI, { useNewUrlParser: true, useUnifiedTopology: true })
  .then(() => console.log('MongoDB connected'))
  .catch(err => console.log(err));

app.use('/api', apiRoutes);

const port = process.env.PORT || 5000;
app.listen(port, () => console.log(`Server running on port ${port}`));
  1. models/Book.js – Book schema for MongoDB:
const mongoose = require('mongoose');
const Schema = mongoose.Schema;

const BookSchema = new Schema({
  title: { type: String, required: true },
  author: { type: String, required: true },
  isbn: { type: String, required: true },
  status: { type: String, enum: ['available', 'borrowed'], default: 'available' },
  borrower: { type: Schema.Types.ObjectId, ref: 'User' },
  dueDate: { type: Date },
});

module.exports = mongoose.model('Book', BookSchema);
  1. routes/api.js – API routes for book management:
const express = require('express');
const router = express.Router();
const bookController = require('../controllers/bookController');

router.post('/add-book', bookController.addBook);
router.get('/books', bookController.getAllBooks);
router.post('/borrow-book/:bookId', bookController.borrowBook);
router.post('/return-book/:bookId', bookController.returnBook);

module.exports = router;
  1. controllers/bookController.js – Book management logic:
const Book = require('../models/Book');

exports.addBook = (req, res) => {
  // Add book logic here
};

exports.getAllBooks = (req, res) => {
  // Get all books logic here
};

exports.borrowBook = (req, res) => {
  // Borrow book logic here
};

exports.returnBook = (req, res) => {
  // Return book logic here
};

Frontend Implementation (React, Axios)

  1. src/components/Auth/Register.js – Registration component (similar to previous examples):
// Registration component similar to previous examples
  1. src/components/Auth/Login.js – Login component (similar to previous examples):
// Login component similar to previous examples
  1. src/components/Catalog/BookCard.js – Component to display book cards:
import React from 'react';

const BookCard = ({ book }) => {
  return (
    <div className="book-card">
      <h2>{book.title}</h2>
      <p>Author: {book.author}</p>
      <p>ISBN: {book.isbn}</p>
      <p>Status: {book.status}</p>
    </div>
  );
};

export default BookCard;
  1. src/components/Catalog/Catalog.js – Component to display the catalog of books:
import React, { useState, useEffect } from 'react';
import axios from 'axios';
import BookCard from './BookCard';

const Catalog = () => {
  const [books, setBooks] = useState([]);

  useEffect(() => {
    async function fetchBooks() {
      try {
        const response = await axios.get('/api/books');
        setBooks(response.data);
      } catch (error) {
        console.error('Error fetching books:', error);
      }
    }
    fetchBooks();
  }, []);

  return (
    <div>
      {books.map(book => (
        <BookCard key={book

._id} book={book} />
      ))}
    </div>
  );
};

export default Catalog;
  1. src/App.js – Main component handling routing:
import React from 'react';
import { BrowserRouter as Router, Switch, Route } from 'react-router-dom';
import Login from './components/Auth/Login';
import Register from './components/Auth/Register';
import Catalog from './components/Catalog/Catalog';

function App() {
  return (
    <Router>
      <Switch>
        <Route path="/login" component={Login} />
        <Route path="/register" component={Register} />
        <Route path="/catalog" component={Catalog} />
      </Switch>
    </Router>
  );
}

export default App;

Note: The provided code snippets are still simplified examples, and you will need to integrate them into a complete application with proper routing, error handling, and UI design. Additionally, you will need to implement the backend logic for book borrowing, returning, and fine calculation.

Remember to replace placeholders like API endpoints, API keys, and data variables with actual values relevant to your project. This outline should help you get started, and you can expand upon it to create a functional Library Management System.
