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.

Spring Data JPA

Spring Data JPA (Java Persistence API) is a widely used specification for managing relational data in Java applications. It helps develop Spring, as it reduces boilerplate code by not implementing read and write operations. It also handles the complex process involved in JDBC-based accessing of database and object-relational mappings.

Before discussing Spring Data JPA, let’s discuss its clear advantages and why it is commonly used in Spring development.

The advantages of Spring Data JPA

The following are the advantages of Spring Data JPA:

  • No-code repositories: Spring Data JPA promotes no-code repositories, which means that we don’t have to write the repository pattern, which creates a lot of repetitive code. It provides a set of interfaces that we can use to extend our classes to apply data-specific implementations.

For example, we have a BlogRepository class in our application; when we extend it with the CrudRepository<Blog...
