Announcing React Native EU 2017

First conference of its kind

As a core contributor to React Native, my focus was always on better developer experience (rnpm) and helping others. Thanks to the community that noticed my efforts, I founded Callstack — a company all about React. I’ve been talking a lot recently about giving back to the community. I think it’s a very important part of the open source and the success of people that raises around such projects like React Native.

Today, I am really excited to announce React Native Europe — the first conference in the world to focus on anything and everything React Native. If you have ever wanted a dive deep into React Native, to share your experience with others, or to meet core contributors in person, this will be a great opportunity. Attendees will also have the opportunity to interact with and hear talks from developers from around the world who are contributing to and building apps with React Native.

Whether you are an experienced React Native developer or just at the beginning of your journey, you will benefit from our great sessions covering various aspects of mobile development.

And it’s not only about the coding this time. The conference will take place in a beautiful city of Poland, Wroclaw. This is a great opportunity for you to not only explore beautiful culture and history of Poland, but also travel around IIWW monuments and see how Europe used to be hundreds years ago. You’ll have plenty of tours to choose from, so better get ready!

Sign up for updates on react-native.eu. We will be announcing the call for papers, conference date, and venue this fall.

Sneak peek of what’s waiting for you

React Native Europe is a two-day conference anything and everything React Native organised by Callstack, Mike Grabowski, Nader Dabit and friends.
