Custom shadow node state allows storing data that persists across node cloning during commits, with platform-specific implementations for iOS (Objective-C++) and Android (Kotlin/C++ via folly dynamic objects). Commit hooks run before each tree commit and can modify any node in the shadow tree — not just custom ones. The guide walks through registering commit hooks via a TurboModule, exposing node registration to JavaScript via JSI bindings, and handling the register/unregister lifecycle from React components. Both iOS and Android implementations are covered in full with code examples. ## Full article daily.dev links to this article rather than hosting it.
