Preface

React has established itself as one of the most popular and widely adopted JavaScript libraries due to its simplistic yet scalable ability to create applications. Quarkus is a fantastic alternative for backend development by boosting developer productivity with features such as prebuilt integrations, application services, and more that bring a new revolutionary developer experience to Java.

This book provides hands-on experience to get started with creating and deploying an end-to-end web application with Quarkus and React. For a simpler understanding, the book has been divided into three main parts. In the first part, you will begin with a basic introduction to Quarkus and its features. You will be taught how to bootstrap a Quarkus project from scratch to create a secure, tested HTTP server for your backend. The second part focuses on the frontend; you will learn how to create a React project from scratch to build the application’s user interface and how to integrate it with the Quarkus backend. The last part shows you how to create cluster configuration manifests and how to deploy them into Kubernetes, along with other alternatives such as Fly.io.

By the end of the book, you will be confident in your skills to combine the robustness of both frameworks to create and deploy standalone, fully functional web applications.

Who this book is for

This book is for backend web developers who have at least some basic experience with Java and who would like to learn React to build full stack apps, by integrating it with a Quarkus-based backend. It is also for frontend web developers with at least some basic experience with JavaScript who would like to implement a backend in Quarkus, integrate it with their frontend, and create full stack web applications.

Basic knowledge of Java and JavaScript is recommended, but any developer experienced just with Java or JavaScript should be able to follow the backend and frontend parts with no problem.

What this book covers

Chapter 1, Bootstrapping the Project, introduces Quarkus and the tooling that will be used, and shows you how to bootstrap a project for an application that will be implemented throughout the book.

Chapter 2, Adding Persistence, shows how to implement a persistence layer in Quarkus using Hibernate and the Java Persistence API (JPA).

Chapter 3, Creating the HTTP API, explains how to create a service layer and use dependency injection to implement an HTTP API in Quarkus.

Chapter 4, Securing the Application, shows how to provide a security layer based on JSON web tokens (JWTs) to protect the HTTP API.

Chapter 5, Testing Your Backend, introduces the Quarkus testing framework and Quarkus Dev Services and explains how to use them to implement tests for your application.

Chapter 6, Building a Native Image, shows you how to create a native executable for your Quarkus application.

Chapter 7, Bootstrapping the React Project, introduces React and the libraries that will be used to implement the frontend part of the application, and shows you how to bootstrap the project.

Chapter 8, Creating the Login Page, explains how to implement the authorization infrastructure and how to create the login page for the frontend side of the application.

Chapter 9, Creating the Main Application, shows how to implement the core features of the application and how to consume the backend’s HTTP API.

Chapter 10, Testing Your Frontend, explains how to implement unit and integration tests for your frontend applications based on React.

Chapter 11, Quarkus Integration, shows how to integrate the frontend application with Quarkus.

Chapter 12, Deploying Your Application to Kubernetes, gives a quick overview of Kubernetes and explains how to deploy the application to a Minikube Kubernetes cluster.

Chapter 13, Deploying Your Application to Fly.io, shows you how to deploy the application to Fly.io and make it publicly available.

Chapter 14, Creating a Continuous Integration Pipeline, introduces GitHub Actions and explains how to create a continuous integration (CI) pipeline.
