App.js Conf

The very first Expo & React Native conference in Europe

As the global health situation is changing we cannot yet tell you when the next App.js Conf may happen. At the same time, we are closely monitoring the news, ready to roll up our sleeves and organize our next event as soon as possible. Stay in touch with us by following us on Twitter or signing up to our newsletter. Stay safe!


Closer look into the future
App.js is a base. It is a place, where every React Native developer feels secure. Attend App.js Conf and meet people that joined the React Native Team at the very beginning. Talk to the authors of your favorite libraries and keep your ears on the ground for their new projects. The future of React Native is now. The future is at App.js.
Meet creators of RN & Expo
Join App.js Conf and listen to the talks by the members of the Expo team. Experience the importance of networking during the conference and run fierce discussions with speakers and other attendees at our evening event. Get first-hand Expo tips during our workshops ran by Expo's creators. Participate, discuss and boost your skills. Make your next mobile app in no time.
Contribute to open-source
The community of open-source developers is similar to a group of scientists. Most of the findings are shared with others and evaluated by them. This way, some of them become commonly accepted facts, others are denied and forgotten. That is more-less how the open-source projects work. Unlike the commercial ones, they develop much closer to the users' needs.
