Full Stack Development with JHipster - Second Edition

By: Deepu K Sasidharan, Sendil Kumar Nellaiyapen

Overview of this book

JHipster is an open source development platform that allows you to easily create web apps and microservices from scratch without spending time on wiring and integrating different technologies. Updated to include JHipster 6, Java 11, Spring Boot 2.1, Vue.js, and Istio, this second edition of Full Stack Development with JHipster will help you build full stack applications and microservices seamlessly. You'll start by understanding JHipster and its associated tools, along with the essentials of full stack development, before building a monolithic web app. You'll then learn the JHipster Domain Language (JDL) with entity modeling using JDL-Studio. With this book, you'll create production-ready web apps using Spring Boot, Spring Framework, Angular, and Bootstrap, and run tests and set up continuous integration pipelines with Jenkins. As you advance, you'll learn how to convert your monoliths to microservices and how to package your application for production with various deployment options, including Heroku and Google Cloud. You'll also learn about Docker and Kubernetes, along with an introduction to the Istio service mesh. Finally, you'll build your client-side with React and Vue.js and discover JHipster's best practices. By the end of the book, you'll be able to leverage the best tools available to build modern web apps.

Walking through the generated files

The files generated by JHipster are organized by application. That is, each application will have its own folder and the files related to that service will be present inside it.

We will start with the store gateway application. There will be three generated files: the store-service.yml, store-mysql.yml, and store-deployment.yml files.

The following is the store-service.yml file:

apiVersion: v1
kind: Service
metadata:
name: store
namespace: jhipster
labels:
app: store
spec:
selector:
app: store
type: LoadBalancer
ports:
- name: http
port: 8080

The first line defines the API version of Kubernetes we want to target, followed by the kind of template or object that this template carries. This template has a service defined in it.

Then, we have the metadata information. Kubernetes uses this metadata information to group certain services...
