A lot shipped this week across React, React Native, and the surrounding ecosystem. New browser APIs landed, libraries evolved, and platform work kept moving. Some of it immediately useful, some of it easier to misread without context.

In this live stream, Kewin Wereszczyński and Łukasz Chludziński go through the latest React and React Native updates and talk through the ones that matter. The goal is to add engineering perspective: what changes behavior, what affects architecture, and what’s likely to stay relevant beyond this release cycle.

The conversation will span React core, browser features, tooling, and mobile, including React Native and Expo. Expect commentary on direction, maturity, and trade-offs rather than announcements repeated verbatim.

Join us live on Thursday, January 22 at 4 pm CET.
