A detailed guide on structuring OpenHarmony projects for enterprise use has emerged, focusing on API23+ standards. The author proposes a modular architecture that separates concerns into layers: foundation, business, and feature modules, each with clear dependency rules. This approach aims to solve common pain points in large-scale OpenHarmony development, such as code reuse, testing isolation, and team collaboration. The guide also covers build configuration using hvigor, version catalog management, and automated code quality checks. For overseas developers, this signals that OpenHarmony is moving beyond hobbyist projects into serious production environments. The modular patterns resemble those used in Android's multi-module setups but are tailored to OpenHarmony's unique distributed capabilities. Teams evaluating OpenHarmony for IoT or smart device fleets should consider adopting similar structures early to avoid technical debt. The post does not include full source code but provides enough architectural insight to be actionable.
This post outlines a comprehensive modular architecture for OpenHarmony projects targeting API23+, including directory structure, dependency management, and testing strategies. It addresses a gap in official documentation for large-scale implementations. The signal is that OpenHarmony is maturing toward enterprise readiness, with structured engineering practices becoming critical for adoption.
