What JHipster does

5. Companies love JHipster
- 200+ companies officially listed on http://www.jhipster.tech/
companies-using-jhipster/
- All industries, all countries
- Many companies contribute back to the project

6. Some statistics on JHipster
- 19 developers in the « core » team
- 380 contributors, including official contributions
from Google, Red Hat and Salesforce
- 8,600+ GitHub stars
- 700,000+ downloads
- conferences all around the world

7. Why Open Source matters
- Brings together a large number of developers
- Different companies
- Different goals
- Different skills
- Higher quality
- Focus on peer review
- No hidden code

8. Legal aspects
- Open Source is all
about licensing
- Being “free” is a
consequence of the
license
- JHipster uses the
Apache 2 license
- Foundations are great
for hosting successful
projects

9. How to run a successful
Open Source project?

10. Drive project awareness
- Be popular in the Internet
- Social networks:
GitHub, Twitter
- News sites:
Hacker News, Reddit
- Do IRL events
- Conferences
- Meetups

11. At the beginning, do
guerrilla marketing
(yes, that’s +1,500
retweets!)

12. Focus on the project, not on marketing
- Marketing is worthless is you
don’t have a great product
- The most important keys to
success:
- Great community
- Great code
- Lots of releases
-> How can you create this great
community?

13. Events and conferences
- Meetups and
conferences are very
important
- Not everybody is on
Twitter!
- We also help people
organize their own
events
- Slides
- Marketing

14. Provide great documentation
- Documentation is very important
- Help beginners and
advanced users
- Documentation must be
versioned
- Let people contribute: the
JHipster documentation
is also an Open Source
project on GitHub
- Provide user guides
- Video tutorials work great
- Our official tutorial has over 90K
views!

15. Make it easy to contribute
- “Contributing” guide
- Issue and Pull Request
templates
- JHipster even has a
specific sub-generator to
help create an issue!
- Easy-to-understand code
- That’s why we use
JavaScript and EJS: not
the best languages, but
the most common and the
easiest to understand

16. Create a welcoming community

17. Code of Conduct
- Most OSS projects now
follow a Code of Conduct
- Very important for a lot of
people
- Our goal is to attract as
many talented people as
possible
- We don’t tolerate brilliant
jerks

18. JHipster Code of Conduct

19. Managing growth
- JHipster’s community has grown so big that it can’t
be handled by a single person
- This is why we created the “core team”

20. Organization of JHipster
- Meritocracy
- People are voted into the
core team
- Core team members
have write access to the
code, to the dev mailing
list, etc.
- Democracy
- All core team members
are equals

21. JHipster policies

22. Quality at scale
- Follow the GitHub
workflow
- Pull Requests, code
reviews
- Code quality guidelines
- Eslint
- Sonar
- Have a great Continuous
Integration system
- Release early, release
often

23. Support channels
- The main trouble is support
- GitHub tickets for bugs
- Great for bugs, as it
integrates with the commits,
code review and CI systems
- Stack Overflow for questions
- Great for questions and
answers, as it has a voting
and reputation system
- Gitter.im for chat
- People helping each other directly
- Open discussions on the project

24. Finding sponsors
- People contributing for free are not always
enough
- Many companies contribute to OSS
projects
- When they find a business interest on
their side
- Example: Salesforce provides Heroku
support for JHipster
- Companies also provide lots of free “gifts”
- In exchange of some advertisement/
support, it’s easy to have free credits
- Example: Google gives $5,000 of free
Google Cloud credits to JHipster

25. The business of Open Source
- Team
- 6 core comiters
- 2 trainees/year
- Investments
- 100 KE/year
- Marketing support
- ROI
- Sales
- Recruitment
- R&D
- Consulting
engagements
- Trainings
