puui-biz monorepo organizes shared libraries, backend-for-frontend (BFF) services, and multi-platform client applications into a cohesive dependency graph. The root coordinates three main branches: bff-core with type definitions and data handlers, a contract layer exposing tracking, APM, A/B config, and request utilities, and platform-specific consumers including web, mini-programs, Harmony Hybrid, and React Native clients. This structure enforces separation of concerns while enabling code reuse across web and native surfaces.
