Book Library in JavaScript

Imagine a world where your love for books meets the elegance of technology—a place where every title, every author, and every genre is just a click away. In today’s fast-paced world, organizing and managing a personal book library can feel like a daunting task. But with the power of JavaScript, you can create a digital library that not only keeps your collection in perfect order but also rekindles your passion for reading. This journey into building a book library in JavaScript is about more than just code; it’s about creating a space where your literary treasures are cherished and easily accessible, making the joy of reading even more fulfilling.

What is a Book Library Application?

A Book Library Application allows users to store a list of books, including details such as the title, author, and genre. The application can serve as a lightweight tool for personal use or a starting point for building more complex systems like a school library management system.

  1. Add New Books: Users can input the details of a new book and add it to the library.
  2. Display Book List: The library can show the full list of books stored.
  3. Remove Books: A book can be deleted from the library by selecting or clicking on it.
  4. Search for Books: A simple search functionality can allow users to find books by title or author.

HTML Structure

We start with the HTML layout that will house our book library UI.

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Book Library</title>
  <link rel="stylesheet" href="styles.css">
</head>
<body>
  <h1>My Book Library</h1>

  <div class="form-container">
    <input type="text" id="bookTitle" placeholder="Book Title">
    <input type="text" id="bookAuthor" placeholder="Author">
    <button id="addBookBtn">Add Book</button>
  </div>

  <h2>Library Collection</h2>
  <ul id="bookList"></ul>

  <script src="script.js"></script>
</body>
</html>

This simple layout consists of:

  • A form with input fields for the book title and author.
  • A button to add the book to the library.
  • An empty <ul> where the list of books will be displayed.

JavaScript for Adding and Removing Books

Next, let’s write the JavaScript code that powers the functionality of our Book Library.

// Select necessary elements
const addBookBtn = document.getElementById('addBookBtn');
const bookList = document.getElementById('bookList');

// Function to add a new book
function addBook() {
  const title = document.getElementById('bookTitle').value;
  const author = document.getElementById('bookAuthor').value;

  if (title && author) {
    const listItem = document.createElement('li');
    listItem.textContent = `${title} by ${author}`;

    // Add remove button
    const removeBtn = document.createElement('button');
    removeBtn.textContent = 'Remove';
    removeBtn.onclick = function() {
      bookList.removeChild(listItem);
    };

    listItem.appendChild(removeBtn);
    bookList.appendChild(listItem);

    // Clear the input fields
    document.getElementById('bookTitle').value = '';
    document.getElementById('bookAuthor').value = '';
  } else {
    alert('Please enter both a title and an author');
  }
}

// Event listener for adding a book
addBookBtn.addEventListener('click', addBook);

This script achieves the following:

  • Adding a New Book: When the “Add Book” button is clicked, the book details are retrieved from the input fields, and a new list item is created.
  • Removing a Book: Each book is listed with a “Remove” button that allows users to delete it from the library.
  • Input Validation: An alert is displayed if the user tries to add a book without providing both a title and author.

CSS for Styling

Lastly, let’s add some simple styling to enhance the look and feel of the application.

body {
  font-family: Arial, sans-serif;
  text-align: center;
  padding: 20px;
}

h1, h2 {
  color: #333;
}

.form-container {
  margin-bottom: 20px;
}

input {
  padding: 8px;
  margin-right: 10px;
}

button {
  padding: 8px 15px;
  background-color: #4CAF50;
  color: white;
  border: none;
  cursor: pointer;
}

button:hover {
  background-color: #45a049;
}

ul {
  list-style-type: none;
  padding: 0;
}

li {
  margin: 10px 0;
  display: flex;
  justify-content: space-between;
}

li button {
  background-color: #f44336;
}

The above CSS code provides basic styling for our HTML elements, giving the application a clean and user-friendly interface
