> JHipster is a development platform that generates production-ready Spring Boot + Angular/React/Vue applications with built-in authentication, CI/CD, and cloud deployment.

## Install

Save as a script file and run:

# JHipster — Full-Stack App Generator for Spring Boot and Modern Frontends

## Quick Use
```bash
# Install JHipster
npm install -g generator-jhipster

# Create a new project
mkdir myapp && cd myapp
jhipster

# Follow the interactive prompts to choose:

# - SQL or NoSQL database
# - Authentication type (JWT, OAuth2, Session)
```

## Introduction
JHipster is a code generator that scaffolds full-stack Java applications combining a Spring Boot backend with a modern JavaScript frontend. It handles boilerplate for authentication, database access, API design, testing, CI/CD pipelines, and cloud deployment so teams can focus on business logic.

## What JHipster Does
- Generates complete Spring Boot applications with Angular, React, or Vue frontends
- Scaffolds JPA entities, REST APIs, and CRUD screens from a JDL domain language
- Configures authentication via JWT, OAuth2/OIDC, or session-based security
- Produces Docker Compose files and Kubernetes manifests for deployment
- Creates CI/CD pipelines for GitHub Actions, GitLab CI, Jenkins, and Azure DevOps

## Architecture Overview
JHipster uses Yeoman as its generator engine. Users answer prompts or provide a JDL (JHipster Domain Language) file describing entities and relationships. The generator produces a Spring Boot backend with Spring Security, Spring Data, and Liquibase migrations, alongside a webpack-bundled frontend. For microservice architectures, it generates a gateway, service registry (Consul or Eureka), and per-service projects with inter-service communication via REST or messaging.

## Self-Hosting & Configuration
- Requires Node.js 18+ and Java 17+ as prerequisites
- Use JDL Studio (online editor) to design entity models visually
- Configure database choice (PostgreSQL, MySQL, MongoDB, Cassandra) during generation
- Customize generated code via blueprints and side-by-side modules
- Deploy to AWS, Azure, GCP, or Heroku using built-in sub-generators

## Key Features
- Supports monolithic and microservice architectures from a single toolchain
- JDL domain language enables rapid entity and relationship modeling
- Built-in Gatling and Cypress tests for load and end-to-end testing
- Elasticsearch integration for full-text search across entities
- Blueprint system allows community extensions for .NET, Quarkus, and more

## Comparison with Similar Tools
- **Spring Initializr** — generates bare Spring Boot projects without frontend or CRUD scaffolding
- **Rails** — opinionated full-stack Ruby framework with conventions over configuration
- **Laravel** — PHP full-stack framework, similar philosophy but different ecosystem
- **Nx + Nest.js** — TypeScript monorepo approach without Java backend generation
- **Hilla** — Spring Boot + Lit/React integration by Vaadin, narrower scope

## FAQ
**Q: Can I use JHipster with an existing Spring Boot project?**
A: JHipster is designed to scaffold new projects. For existing projects, you can use the entity sub-generator or adapt the generated code, but full integration requires starting from a JHipster-generated base.

**Q: Does JHipster support GraphQL?**
A: Not out of the box. REST is the default API style. GraphQL support is available through community blueprints.

**Q: How do I update a JHipster project to a new version?**
A: Run `jhipster upgrade` to regenerate the project with the latest templates while preserving custom code via git merge.

**Q: Is JHipster suitable for production?**
A: Yes. Generated applications include production-grade defaults for security, caching (Ehcache, Hazelcast, Redis), monitoring (Micrometer + Prometheus), and database migrations.
