  "textContent": "Recently, I migrated a production React Native application from the Legacy Architecture to the New Architecture (Fabric + TurboModules + JSI).\n\nWhat looked like a simple configuration change:\n\nnewArchEnabled=true\n\nturned into a journey of debugging navigation issues, Fabric rendering glitches, Reanimated crashes, and third-party library incompatibilities.\n\nKey Lessons\n\n✅ Audit every dependency before enabling New Architecture.\n\n✅ Upgrade React Navigation, Reanimated, and Gesture Handler first.\n\n✅ Avoid navigation calls during render; use useEffect.\n\n✅ Test on real devices, not just simulators.\n\n✅ Enable New Architecture gradually in staging before production.\n\nIssues We Faced\nCannot apply update because surface was stopped\nSurface already running\nFabric layout inconsistencies\nReanimated worklet crashes\nNative module compatibility issues\nWhat Improved?\nFaster app startup\nSmoother animations\nBetter list performance\nReduced JS ↔ Native communication overhead\nFinal Thought\n\nThe New Architecture is not just an upgrade—it's a platform migration. The effort is worth it, but plan carefully, audit dependencies, and migrate incrementally. React Native's future is built around Fabric, TurboModules, and JSI.",
