NodeConf Barcelona 2017, A Retrospective

Podiums discussion at NodeConf Barcelona 2017 It was with immense passion and pleasure that the team here at worked tirelessly to bring another . But, this isn’t about us, it’s about the event itself. So, without much further ado, let’s get down to the retrospective. Let’s see what we did well, and what we can do better next time.

By The Numbers

NodeConf Barcelona 2017 was the second NodeConf to be hosted in Barcelona (the third, if you count ). In 2015, the first NodeConf Barcelona attracted roughly 100 attendees, with 13 speakers, mostly from Europe, with 4 out of the 13 speakers (31%) being female. This year, NodeConf Barcelona attracted 150 attendees from 15 countries. We had 12 speakers, from inside and outside the European Union, with 5 out of 12 speakers (42%, an 11% increase) being female. But it wasn’t just by the numbers that NodeConf Barcelona did well in 2017, the feedback from both attendees and speakers was also phenomenal.

Really an awesome couple days connecting with the people at  — thanks for a fantastic event. Until next time !

The Inspiring Talks

This year, we had a lineup of 12 amazing speakers sharing their learnings and thoughts on a variety of NodeJS and DevOps topics. As always, we strive for diversity and greater representation at our conferences. So, we were very happy to welcome speakers from outside of Europe, as well as have 5 out of 12 speakers (42%) be female. Hopefully, next year, we’ll cross the 50% boundary on that one!

Jan Lenhardt: Kill All Humans

Jan opened the day with his ‘scarily’ titled talk: “Kill All Humans”. Luckily, all the attendees survived this informative session about development tool automation. Whilst you should watch Jan’s session yourself online, our favourite takeaways were:

• Hauptversionsnummernerhöhungsangst: The German word for fear of increasing the major version number
• Semantic Versioning makes the ecosystem and library usage reliable as you can see by the number if this is a breaking change to your code
• Greenkeeper keeps your libraries up-to-date

Thanks all for being a great audience at . If you have any question about or , find me ✌️
