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.

Walking through the generated files

The files generated by JHipster are in the following structure. 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 gateway application. There will be three generated files, which will be the gateway-service, gateway-mysql, and gateway-deployment.yml files.

The following is the gateway-service.yml file:

apiVersion: v1
kind: Service
    name: gateway
    namespace: default
        app: gateway
        app: gateway
    type: LoadBalancer
 - name: web
   port: 8080

The first line defines the API version of Kubernetes, followed by the kind of template or object that this template carries. This template will have a service inside of it. 

Then, we will have the metadata information. Kubernetes uses this metadata information to group certain services together. In the metadata, we can define:

  • The service name
  • The namespace it belongs...
