Case Introduction

Customer Pain Points
As the HarmonyOS ecosystem expands, a leading smart home client required rapid adaptation of their mature React Native app (already on Android/iOS). The migration faced five core pain points:
Solution
We executed a systematic, four-phase adaptation strategy:
1.Precision Gap Analysis
- Mapped 117 adaptation points within the React Native framework and analyzed over 140 key native third-party libraries to build a clear adaptation roadmap.
2.Cross-Platform Logic Alignment
- Went beyond simple API mapping to align Android and iOS interaction logic with HarmonyOS design paradigms, ensuring a native-optimal user experience.
3.Targeted API Adaptation
- Leveraged HarmonyOS native APIs to systematically resolve compatibility issues and implement all core functions with high performance.
4.Automated Migration Tooling
- Developed forward-looking automation scripts covering 110+ scenarios to handle RN version upgrades, drastically improving efficiency and future-proofing the client's tech stack.
Project Value
Hybrid architecture enables decoupling and hot updates for agile iteration. Self-developed scaffold cuts migration barriers and boosts dev efficiency 50%+. Compilation 5x faster, package 1/3 smaller, enabling lightweight deployment and seamless domestic IT ecosystem migration.
1.Decoupled Architecture for Agility
Implemented a "Native Framework + RN Panel" hybrid model. Business logic is developed in React and loaded dynamically via standardized HAR packages, supporting hot updates and rapid iteration.
2.Scaffolding Drives 50%+ Efficiency Gain
Developed a custom migration scaffolding tool that auto-generates initialization code, interface mappings, and parameter conversions based on RN API definitions. This reduced dependency on RN expertise and boosted development efficiency by over 50%.
3.Performance Breakthrough
Optimized CMake scripts and introduced pre-compilation and bytecode compilation (C++ to SO files). Achieved a 5x compile speed increase and reduced package volume by two-thirds.
4.Lossless Digital Migration
Successfully bridged the architectural gap between Windows and HarmonyOS, achieving a seamless, functional migration of mature software into the domestic IT ecosystem.
