React Native EU 2020 marked a significant milestone as our conference transitioned to a fully virtual format on September 3–4, 2020. This edition brought together nearly 6,000 participants from around the globe, engaging in 23 live-streamed talks delivered by 24 speakers from leading organizations like Facebook, Microsoft, Artsy, and Expo. The sessions delved into a wide array of topics, including cross-platform development, performance optimization, testing methodologies, native module integration, and GraphQL data management.

Attendees had the opportunity to explore innovative tools and libraries such as SyncState, URQL, and XcodeGen, and gain insights into React Native's new architecture, including CodeGen, JSI, and TurboModules. The conference also featured discussions on performance profiling, visual regression testing, and strategies for managing large-scale React Native applications.
