Introduction

React Native EU is an annual conference that brings together developers, industry leaders, and enthusiasts from around the world to share their knowledge, experience, and insights about the popular cross-platform framework, React Native.

React Native EU is the largest React Native conference in Europe, and if you are interested in React Native, this is the one event you don't want to miss. Frequently, developers from Meta unveil new developments at this conference or Chain React in the US. Back in 2019, I took a long flight from Taiwan to Portland just to attend the Chain React conference, and the experience was amazing. At that event, Tzvetan from Meta announced the Hermes engine, which was a game-changer. Tzvetan will also be attending React Native EU this year, and it's exciting to anticipate what Meta will unveil.

Major themes

This year, speakers from large companies such as Meta, Microsoft, PlayStation, Amazon, Shopify, and JPMorgan Chase will share insights on scaling, building systems, and infrastructure around React Native. Since the technology has already been widely adopted in the industry, you can expect to learn more about how things work at scale.

Keynotes

This year, the keynotes will be hosted by Alex and Riccardo from Meta, and Łukasz from Callstack. Details have not been revealed yet, but I predict they might discuss the React Native Developer Experience. You may have heard earlier this year that the Meta team decoupled Flipper from the React Native core. Currently, Expo supports debugging with Chrome DevTools and the Network Inspector. Kudos to Kudo, who bridged the gap by implementing the Chrome DevTools Protocol (CDP). Though information from Meta is uncertain, we could expect more CDP implementation in version 0.74.
