REACT NATIVE HARDENS BUILD PIPELINE WHILE FIXING ANDROID TEXT RENDERING

By RepoJournal · Filed 06:03 UTC on June 9, 2026 · About Meta

React Native shipped critical infrastructure upgrades overnight: OIDC token replacement for npm publishing, AGP v9 adoption across the stack, and a text decoration rendering fix that restores native Android behavior.

The biggest story is npm publishing security [1]. React Native replaced long-lived `GHA_NPM_TOKEN` automation tokens with OIDC Trusted Publishing via a reusable workflow, eliminating a critical attack surface for package compromises. Alongside that, the team adopted Android Gradle Plugin v9 repository-wide [2], deprecating legacy APIs and modernizing the entire build graph. That same modernization work includes removing the folly::Endian dependency from JSIndexedRAMBundle [4], cutting unnecessary build overhead by inlining a simple little-endian decoder. On the stability front, a recent change that switched Android text decoration to custom canvas drawing inadvertently increased stroke thickness by 1.5dp [3]. The fix removes the minimum thickness enforcement, restoring native Android behavior. A minor CI fix landed for gradle.properties templating [5], but it's a cleanup that unblocks template testing.
