Full Stack Development with JHipster,

By: Deepu K Sasidharan, Sendil Kumar Nellaiyapen

Overview of this book

JHipster is a development platform to generate, develop, and deploy Spring Boot and Angular/React applications and Spring microservices. It provides you with a variety of tools that will help you quickly build modern web applications. This book will be your guide to building full stack applications with Spring and Angular using the JHipster tool set. You will begin by understanding what JHipster is and the various tools and technologies associated with it. You will learn the essentials of a full stack developer before getting hands-on and building a monolithic web application with JHipster. From here you will learn the JHipster Domain Language with entity modeling and entity creation using JDL and JDL studio. Moving on, you will be introduced to client side technologies such as Angular and Bootstrap and will delve into technologies such as Spring Security, Spring MVC, and Spring Data. You will learn to build and package apps for production with various deployment options such as Heroku and more. During the course of the book, you will be introduced to microservice server-side technologies and how to break your monolithic application with a database of your choice. Next, the book takes you through cloud deployment with microservices on Docker and Kubernetes. Going forward, you will learn to build your client side with React and master JHipster best practices. By the end of the book, you will be able to leverage the power of the best tools available to build modern web applications.

Live reload for development

When developing an application, one of the most annoying and time-consuming parts is recompiling the code and restarting the servers to see the code changes we have made. Traditionally, JavaScript code used to be easier, as it didn't need any compilation and you could just refresh the browser and see the changes. However, even though current MVVM stacks make the client side more important than before, they also introduce side effects, such as transpiling of client-side code, and more. So, if you are refactoring a field for an entity, you would traditionally need to do the following tasks to see the changes in your browser:

  1. Compile the server-side Java code.
  2. Apply the table changes to the database.
  3. Recompile the client-side code.
  4. Restart the application server.
  5. Refresh the browser.

This takes a lot of time, is frustrating to do for every small change, and results in you making more changes before checking them, hence affecting productivity.
