majiayu000 Monorepo Boundaries (REQUIRED)
- ALWAYS keep application code inside
apps/*. - ALWAYS keep reusable code inside
packages/*. - NEVER import app code from another app (e.g.
apps/webimporting fromapps/mobile). Extract shared logic into a package.
Package Design (REQUIRED)
- ALWAYS design packages as platform-agnostic when possible.
- ALWAYS expose stable entrypoints from each package (avoid deep imports across packages).
- NEVER duplicate shared UI or utilities across apps; add/extend a package instead.
Cross-Platform UI Rules (REQUIRED)
- ALWAYS prefer shared UI in
packages/ui. - ALWAYS keep platform-specific implementations behind explicit entrypoints (e.g.
*.native.tsx,*.web.tsx) when needed. - NEVER assume DOM APIs exist in mobile code.
Dependency & Ownership Rules
- ALWAYS keep dependencies as low as possible in packages.
- ALWAYS add dependencies at the narrowest scope that needs them (package/app
package.json, not the root). - NEVER add a dependency to the root unless it is truly repo-wide tooling.
