Are you aspiring to create a sophisticated book rental application? Dive into this guide to learn how to build a seamless application using Java Spring Boot for the backend and React JS for the frontend. We will explore the critical components of the application, including API routes, database management with PostgreSQL, and user roles.

Understanding the Components

This application serves as a library system where a librarian can manage book rentals effortlessly. Imagine being a librarian who efficiently organizes books, assists patrons, and maintains a systematic approach to book lending. Here’s a breakdown of the components involved:

• Backend (Java Spring Boot): This acts as the engine of your application, handling requests, and managing data flows.
• Frontend (React JS): Think of this as the interactive face of your application that users will see and engage with.
• Database (PostgreSQL): Picture a vast library where all the data is stored and organized.

Key Features of the Application

The book rental module caters specifically to users with librarian roles, granting them multiple privileges:

• Add new books to the collection.
• Delete books that are no longer in good condition.
• Modify book entries.
• Mark books as rented.

Application Requirements

Here’s how the user interacts with the application:

• All available books are displayed on the home page. You can navigate to this via books path.
• Each book has an Edit, Delete, and Mark As Taken button for easy management.
• Clicks on the Edit or Delete buttons trigger calls to the API for modifications.
• Clicking the Mark As Taken button reduces the number of available copies through an API call.
• There’s a prominent button to add a new book to the collection.
• A header section acts as a navigation menu to aid user experience.

Putting It All Together: An Analogy

Imagine running a bustling library. Each book is yours to manage, just like your application’s data. When a new book arrives, you carefully place it on the shelf (adding a book in the application). When a book is torn and worn out, you remove it from circulation (deleting a book). Want to change the book’s title? You wouldn’t just slap a sticker on it; you’d ensure the catalog (database) is updated as well (modifying a book). When a patron checks out a book, you notate that it’s rented (decreasing available copies). All of these operations happen seamlessly at the click of a button, just like the buttons on your app’s interface.

Troubleshooting Tips

While building this application, you may encounter challenges. Here are some common troubleshooting ideas:

• Ensure that your Java Spring Boot server is running properly. You can check the console logs for any error messages.
• If your frontend is not displaying data, verify the API endpoints you are calling and ensure they are correctly configured.
• Check your PostgreSQL database for any missing entries or incorrect data types that could lead to errors.
• If you face issues with buttons not functioning as expected, inspect the console for any JavaScript errors.
• If you continue to encounter challenges, consider reaching out for help or collaboration. For more insights, updates, or to collaborate on AI development projects, stay connected with fxis.ai.
