Spring Boot 3 and Next.js 13: A Hands-On Approach

Welcome to Spring Boot 3 and Next.js 13: A Hands-On Approach!

In this book, we will take a guided tour of Spring Boot 3, a Java framework for creating RESTful APls with minimal boilerplate code and configuration, and Next.js, a React framework for client-side rendering.

The best way to learn something new is to be active in the learning process. Throughout the book, we will structure learning by building a full-stack web application called Expensify.

Expensify is a fictional expense reimbursement platform. Employees of a company submit expenses for reimbursement, and reviewers approve or reject these expenses. The purpose of an expense reimbursement platform is to provide a way for employees to get their money back for things they buy for work (e.g., flight tickets, hotel accommodations, food, etc.). Reviewers approve or reject expenses based on whether the spending was appropriate based on company policies.

I wrote this book because I was interested in learning Spring Boot and Next.js for a side project, but I found myself having to piece information together from various resources, such as official documentation, tutorials, and Stack Overflow. These resources, while helpful, often left me with more questions than answers. I longed for a resource that would not only teach me how to do something but also why I needed to do it in the first place.

The frustration I experienced inspired me to embark on a journey to write the book I wish I had when I was starting.

By the end of this book, you will have built a full-stack web application, and along the way, you will have developed a better understanding of Spring Boot and Next.js.

I do not claim you will be an expert in these frameworks by the end of the book, nor will you be completely ready for the complexity of full-stack web applications in the real world. 

What I can say is that you will have foundational knowledge from which to expand upon now that you know the basics.
