Angular makes building applications with the web easy and Spring Boot helps get an application up and running using just a few lines of code and minimal configuration. This book provides insights into building full-stack apps using Angular and Spring Boot effectively to reduce overall development time and increase efficiency.

You'll start by setting up your CI/CD pipeline and then build your web application's backend guided by best practices. You'll then see how Spring Boot allows you to build applications faster and more efficiently by letting the Spring Framework and Spring Boot extension do the heavy lifting. The book demonstrates how to use Spring Data JPA and add its dependencies along with Postgres dependencies in the project to save or persist a user's data in a database for future use. As you advance, you'll see how to write tests and test a service using Mockito. Finally, you'll create a CI workflow or pipeline for a Spring Boot and Angular application to enable operations to deliver quality applications faster.

By the end of this Spring Boot and Angular book, you'll be able to build a full-stack web application and deploy it through continuous integration and continuous deployment.

Preface

Spring Boot provides JavaScript users with a platform to get an application up and running with just a few lines of code. At the same time, Angular is a component-based framework that makes building a web application’s frontend easy. This book explains how Spring Boot and Angular work together to help you create full-stack applications quickly and effectively.

In this book, you will begin by exploring why Spring Boot and Angular are in-demand frameworks, before being guided by expert solutions and best practices to build your own web application. Regarding the backend, you will see how Spring Boot allows you to build applications efficiently by letting the Spring Framework and Spring Boot extension do the heavy lifting, while using Spring Data JPA and Postgres dependencies in your project to save or persist data in a database. With the frontend, you will use Angular to construct a project architecture, build Reactive forms, and add authentication to avoid malicious users stealing data from the application.

Finally, you will see how to test services with Mockito, deploy applications using continuous integration and continuous deployment, and integrate Spring Boot and Angular to create a single package so that, by the end of the book, you will be able to build your very own full-stack web application.

Who this book is for

The book is for busy Java web developers and TypeScript developers with little experience of developing Angular and Spring Boot apps who want to learn about the best practices for building full-stack web apps.

What this book covers

, , serves as a short recap regarding Spring Boot and Angular’s current state to give you a glimpse of what lies ahead in the web development of Java Spring Boot and Angular. You will also see how stable and reliable Vue.js is as an app and the team behind writing and maintaining the Vue.js framework.

, , teaches you how to set up your computer’s development environment to build backend and frontend web applications. We will turn to different IDEs and text editors to write the code and make sure everything has been set up before we proceed in the app development.

, , uncovers the inner workings of Spring Boot and how to start a project using Spring Initializr. This chapter will also teach you about the concept of dependency injection and the IoC container. This chapter will also tackle how Beans and annotations work.

, , helps you to connect the Java Spring Boot to a database. This chapter will describe Spring Data JPA and how to add Spring Data JPA and Postgres dependencies in the project. This chapter will also show how to use a config file to connect the Java Spring Boot to a Postgres database instance.

, , shows you how to start and run a Java Spring Boot application. This chapter will also show how to add models for the application and use them when writing routers and controllers. Afterward, this chapter will explain how to use Redis for caching to improve the performance of an application.

, , covers the documentation part of the APIs of the Java Spring Boot application. This chapter will also show you how to include the Swagger UI in the application to provide graphical interfaces in the documentation of APIs.

, , details what CORS is and how to add a CORS policy in the Spring Boot application. This chapter describes Spring security, authentication, and authorization. This chapter will also demonstrate how JSON web tokens work and what Identity as a Service (IaaS) is.

, , explains what logging is and what the popular packages to implement logging are. This chapter will also teach you where to save logs and what to do with logs.

, , is all about writing tests for a Java Spring Boot application. This chapter describes JUnit and AssertJ. This chapter will also teach you how to write tests, how to test a repository, and how to test a service using Mockito.

, , focuses on how to organize features and modules, how to structure components, and how to add Angular Material.

, , demonstrates how to build Reactive forms, basic form control, and grouping form controls. This chapter will also explain how to use FormBuilder and validate form input.

, , covers state management in complex applications. This chapter will also introduce NgRx and how to set it up and use it in an Angular application.

, , describes how to remove an item using NgRx, how to add an item using NgRx, and how to update an item using NgRx.

, , explores how to add user login and logout, retrieve user profile information, protect application routes, and call an API with protected endpoints.

, , illustrates how to write basic Cypress tests and how to mock HTTP requests for testing.

, , exemplifies how to utilize the Maven frontend plugin for Angular and Spring Boot to integrate them into one package.

, , describes CI/CD and GitHub Actions. This chapter will also show you how to create a CI workflow or pipeline for a Spring Boot and Angular application.

Don’t lose hope if you are facing problems when installing runtimes, SDKs, or any software tools in general when developing an application. Errors are common, but searching for error messages on Google greatly helps developers when troubleshooting certain problems.

If you are using the digital version of this book, we advise you to type the code yourself or access the code from the book’s GitHub repository (a link is available in the next section). Doing so will help you avoid any potential errors related to the copying and pasting of code.

Play around with Angular on stackblitz.com or codesandbox.io to see the look and feel of Angular without installing anything on your computer.
