React Native: Closing the Gap Between Native Bridges and the Web
Today's activity centers on cross-boundary correctness — matching CSS gradient parsing to browser behavior, eliminating unnecessary memory copies between JavaScript and native TurboModules, and fixing recovery bugs in iOS build tooling. Two duplicate security patches for a Metro dependency also landed within an hour of each other.

You're listening to React Native, August 11th, 2026.
The clearest pattern today is React Native tightening the seams between JavaScript, native code, and the web platform it's meant to mirror.
Start with rendering correctness. Thibault Malbranche shipped two related fixes to radial gradient parsing. PR 57873 fixes a bug where specifying a position after an explicit size silently corrupted the gradient's size values. PR 57874 builds on that fix to reject percentage radii on circular gradients, matching how…
Second theme: reducing copies at the native bridge. Two PRs from paradowstack introduce zero-copy ArrayBuffer handling — PR 57879 for Objective-C TurboModules and PR 57897 for the Java side. Previously, every ArrayBuffer crossing the bridge got copied into new memory, which blocked in-place mutation and cost…
Third theme: build reliability. Commit a772a7c fixes a subtle iOS bug where an interrupted core library swap could leave a stale marker file, causing future builds to link the wrong configuration and fail with undefined symbols. The fix writes the marker before touching the framework, so a crash mid-swap is now…
Worth flagging: two nearly identical PRs, 57894 and 57895, both…
