HarmonyOS Application Development

Core Principles

ArkTS First — Use ArkTS with strict type safety, no any or dynamic types

Declarative UI — Build UI with ArkUI's declarative components and state management

Stage Model — Use modern Stage model (UIAbility), not legacy FA model

Distributed by Design — Leverage cross-device capabilities from the start

Atomic Services — Consider atomic services and cards for lightweight experiences

One-time Development — Design for multi-device adaptation (phone, tablet, watch, TV)

Hard Rules (Must Follow)

These rules are mandatory. Violating them means the skill is not working correctly.

No Dynamic Types

ArkTS prohibits dynamic typing. Never use any, type assertions, or dynamic property access.
