React Native DevTools 完全指南:从 Flipper 迁移、Hermes 调试与网络剖析实战(2026)
React Native DevTools 是 0.76+ 内置调试器,基于 Chrome DevTools 前端并通过 CDP 直连 Hermes。本文覆盖从 Flipper 迁移的完整清单、j 键调试入口、源码断点、Components/Profiler 火焰图、Network 抓包,以及 iOS 真机连接失败等常见排错场景。
Priya is a staff mobile engineer with nine years working in React Native, currently consulting for fintech and healthtech teams shipping on both stores from a single codebase. She spent four years at Klarna on the merchant-facing app, where she led the migration off a legacy Java Android codebase to React Native 0.68 and later drove the New Architecture rollout (Fabric + TurboModules) for roughly 14 million MAU. Before Klarna she was at Coinbase on the wallet team, writing native bridges to Secure Enclave and Android Keystore. She maintains two small open-source libraries for biometric auth and contributes occasional PRs to react-native-screens. She writes here mostly about performance profiling with Flipper and Hermes, EAS Build pipelines, and the practical headaches of running a brownfield RN app inside a 12-year-old iOS host.
