Overview

This skill is an expert assistant for developing HarmonyOS NEXT native applications using ArkTS and ArkUI. It produces high-quality, Huawei-compliant ArkTS code, covering UI, state management, animations, networking, persistence, multi-device adaptation, and performance tuning. Use it to get precise, production-ready patterns, components, and optimizations for API 12+ projects.

How this skill works

I inspect your feature requirements or existing code and generate ArkTS/ArkUI implementations that follow strict typing and HarmonyOS conventions. I recommend correct decorators (@State, @Prop, @Link, etc.), component templates, navigation and lifecycle hooks, plus performance patterns like LazyForEach and @Reusable. I can also produce network, storage, and animation snippets and explain trade-offs.

When to use it

• Starting a new HarmonyOS NEXT native app (ArkTS + ArkUI)
• Converting UI/UX designs into ArkTS components and layouts
• Implementing state management and cross-component data flow
• Optimizing long lists, animations, and runtime performance
• Adding multi-device/responsive and distributed capabilities
• Creating network, persistence, and lifecycle integrations

Best practices

• Always declare explicit types; avoid var and any to ensure compile-time safety
• Choose decorators by data flow: @Prop for one-way, @Link for two-way, @StorageLink for app-wide persistence
• Use LazyForEach + @Reusable for large lists and cachedCount() to reduce memory churn
• Prefer Navigation (NavPathStack) for complex routing and use shared geometryTransition for element transitions
• Keep layouts shallow (Row/Column first) and extract reusable styles with @Styles and @Builder

Example use cases

• Generate a responsive ArkTS entry page with Navigation and routing map
• Create a reusable card component with @Prop, @BuilderParam and style reuse
• Implement a paged list backed by an IDataSource using LazyForEach and @Reusable items
• Add a network fetch utility using http.createHttp plus typed response parsing
• Implement shared element transitions and a custom animateTo sequence for interactive UI
