Summary
This is a comprehensive guide for building HarmonyOS apps with the modern Stage model and ArkTS. It's laser-focused on the hard rules that trip up developers coming from other frameworks: strict typing with no dynamic types, immutable state updates for reactive UI, and proper component composition. You get practical patterns for state management decorators (@State, @Link, @Provide), a clear project architecture, and real code examples showing both the wrong and right way to handle common scenarios. If you're building for HarmonyOS NEXT or working with distributed capabilities, this covers the core patterns and gotchas you need to know upfront.
