Community stories

8.
● Stephen is one of our community members from Kenya
● Because of COVID-19, he was without a job and could not afford his medication
● As soon as we learned about his situation
○ Many community members sent him money
○ We also blocked some bug bounties issues for him
● This allowed Stephen to buy his medication!
● And he got a job offer from a US company specialized in JHipster, https://newwave.io/ (kudos to Patrick, their CEO)!!
Stephen Maingi’s story

9.
● “Scouts et Guides de France” is France’s largest scout organization, with 88,000 members
○ This includes many young children, starting at age 6
● As this is a non-profit organization, their volunteers wanted to have a fast and robust platform to build a very
important application
○ The application is for managing alerts in all of their camps
○ This includes lost children or COVID-19 outbreaks
○ It went live during this summer!
○ They are so happy with JHipster that they will probably start another application with it in 2021

JHipster Control Center is a separate JHipster application that will allow you to manage and control all your microservice or
monolith applications from a single place.
● Spring Cloud is used to reach your applications, 4 modes are supported:
○ Eureka server
○ Consul Server
○ Kubernetes
○ A static range URI
● You can log to JHCC through JWT or OAuth2
● You can test your API through a unified Swagger-UI
● The management UI is developed with Vue

● Protractor or Cypress
Here 3 applications with Angular, React and Vue, who can guess ?
Vue.js

18.
Still in discussion at github.com/jhipster/generator-jhipster/issues/11122
● Generate a JHipster project
● Refactor it to an Hexagonal Architecture
● Show case : aggregates, entities, value objects, domain events, etc.
● Discuss with the community
● Start a blueprint ?
Values:
● Clean Architecture
● Split the generated code from the business code
● Easier to change adapters (ex: MySQL -> PostgreSQL)
● Easier to upgrade JHipster application
● For generator-jhipster, easier to maintain existing options
● Easier to add new features (ex: new Database) through ports and adapters
We’ll talk about this subject at twitch.tv/ippontech
