📖 Minimalist Book Manager API

Introduction

This is the starter repository for the Further APIs session. It provides a start to creating a Minimalist Book Manager API using a Test-Driven Development approach.

Pre-Requisites

• Java SE Development Kit 17
• Maven

Technologies & Dependencies

• Spring Boot
• Spring Web
• H2 Database
• Lombok
• Spring Data JPA

How to Get Started

Tasks

Here are some tasks for you to work on:

📘 Discussion Task

Explore the code and make notes on the following features and how it is being implemented in the code. We'd like you to note down what classes and methods are used and how the objects interact.

The features are:

• Get All Books
• Get a Book by ID
• Add a Book
• Update a Book

📘 Task 1: Implement the following User Story with tests.

User Story: As a user, I want to use the Book Manager API to delete a book using its ID

📘 Extension Task: Oh no! 😭 We've only covered the happy paths in the solution, can you figure out a way to add in exception handling to the project?

• Clue 1: What if someone wants to add a book with an ID for a book that already exists? How do we handle this gracefully?

• Clue 2: What if someone wants to find a book by an ID that doesn't yet exist? How can we improve the API by handling errors gracefully and show a helpful message to the client?
