Spring Boot and Angular

By: Devlin Basilan Duldulao, Seiji Ralph Villafranca

Overview of this book

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.

What this book covers

Chapter 1, Spring Boot and Angular – The Big Picture, 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.

Chapter 2, Setting Up the Development Environment, 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.

Chapter 3, Moving into Spring Boot, 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.

Chapter 4, Setting Up the Database and Spring Data JPA, 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.

Chapter 5, Building APIs with Spring, 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.

Chapter 6, Documenting APIs with OpenAPI Specification, 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.

Chapter 7, Adding Spring Boot Security with JWT, 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.

Chapter 8, Logging Events in Spring Boot, 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.

Chapter 9, Writing Tests in Spring Boot, 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.

Chapter 10, Setting Up Our Angular Project and Architecture, focuses on how to organize features and modules, how to structure components, and how to add Angular Material.

Chapter 11, Building Reactive Forms, 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.

Chapter 12, Managing States with NgRx, 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.

Chapter 13, Saving, Deleting, and Updating with NgRx, describes how to remove an item using NgRx, how to add an item using NgRx, and how to update an item using NgRx.

Chapter 14, Adding Authentication in Angular, explores how to add user login and logout, retrieve user profile information, protect application routes, and call an API with protected endpoints.

Chapter 15, Writing Tests in Angular, illustrates how to write basic Cypress tests and how to mock HTTP requests for testing.

Chapter 16, Packaging Backend and Frontend with Maven, exemplifies how to utilize the Maven frontend plugin for Angular and Spring Boot to integrate them into one package.

Chapter 17, Deploying Spring Boot and the Angular App, 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.
