JHipster: Micronaut + Angular + SQL Database CRUD example

Hello everyone, today we will learn how to generate a Monolithic Full-stack web application that is a basic Employee Management Application using JHipster. Technologies used: Micronaut, Angular, H2DB, Maven.

User Interface



JHipster is an open-source application development platform to quickly generate, develop, & deploy modern web applications & microservice architectures using Angular or React or Vue and Spring Boot or Micronaut Frameworks.
Micronaut is a modern, JVM-predicated, full-stack Java framework designed for building modular, facilely testable JVM applications with support for Java, Kotlin and the Groovy language.

JHipster Micronaut Environment Setup

Step 1: Install Java 11, click here

Step 2: Install Node.js, click here

Step 3: Install JHipster using the following command
npm install -g generator-jhipster@6.10.5
or
yarn global add generator-jhipster@6.10.5
or
Download the JHipster Docker image, click here

Step 4(Optional)
Install Maven or Gradle depends on you.
You normally don’t have to install anything, as JHipster will automatically install the Maven Wrapper or the Gradle Wrapper for you. If you don’t want to use those wrappers, go to the official Maven website or Gradle website to do your own installation.

Step 5: Install the JHipster Micronaut blueprint:
npm install generator-jhipster-micronaut@1.0.0

Creating a Web App using JHipster

Step 1Create an empty directory in which you will create your application.

Running the Application

Once the application is generated, you can launch it using 
Maven 
./mvnw
Gradle
