Spring Boot and Angular

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.

Getting started with SLF4J and Log4j2

Logging is considered one of the most important aspects of developing an application. Its importance tends to be underrated and, worse, we forget to apply it to our applications.

Event logging is used in most tech industries, especially those providing enterprise applications. It is applied with a given standard to prevent complex debugging and allow for an easier understanding of the code we are reading. A well-written and structured log can benefit developers, especially when maintaining or debugging code from another developer. Instead of searching exhaustively for an error, records will expedite the debugging process, providing information on where and why the error occurred, and what has happened in our application.

Logging has also evolved with improvements in languages and frameworks; in backend development, several logging frameworks have been developed to provide more flexible logging capabilities. Some of the example frameworks...
