Mortezakoohjani 6f4a484051 Migrate Beauty, Healthcare, and Accounting frontend to modular src/modules architecture. 
Move business logic out of App Router into module packages, add boundary validation scripts, and keep all routes as thin re-exports without changing URLs or API behavior.

Date: 2026-07-26

Dev dependencies

Package Version Purpose
typescript ^5.4.0 Type checking
tailwindcss ^3.4.0 Styling
autoprefixer ^10.4.0 CSS post-processing
postcss ^8.4.0 CSS pipeline
@types/* various Type definitions

Unused dependency impact

Package Bundle impact Recommendation
@tanstack/react-table Tree-shaken if unused, but adds install size Remove unless table upgrade planned
recharts Same Remove until analytics charts implemented

2. Internal Dependency Graph

Layer model (verified acyclic)

Layer 0: styles/, public/
Layer 1: lib/utils.ts, lib/auth.ts
Layer 2: lib/api.ts, lib/theme.ts, lib/identity.ts
Layer 3: lib/{module}-api.ts, lib/{module}-portals.ts
Layer 4: hooks/
Layer 5: components/ds/
Layer 6: components/{module}/
Layer 7: app/

Circular dependencies detected: 0

Internal dependency hotspots

File Inbound refs Outbound deps Role
lib/utils.ts ~47 clsx, tailwind-merge Utility hub
lib/auth.ts ~15 — Token/session management
hooks/useTenantId.ts ~67 useMe, lib/auth Most-referenced hook
components/ds/index.ts ~90+ ds internals, lib/utils DS barrel
lib/accounting-api.ts ~30 lib/auth Accounting API monolith
lib/beauty-business-api.ts ~28 lib/auth Beauty API monolith
lib/healthcare-api.ts ~14 lib/auth Healthcare API monolith

3. API Client Monoliths

Structure (common pattern)

All three module API clients follow identical architecture:

import { getValidAccessToken, refreshSession } from "@/lib/auth";

const BASE = typeof window !== "undefined"
  ? "/api/{service}"                    // browser → BFF
  : process.env.NEXT_PUBLIC_*_API_URL;  // SSR → direct

export class {Module}ApiError extends Error { status, body }

async function request<T>(path, options): Promise<T> {
  // token refresh, x-tenant-id header, error mapping
}

export const {module}Api = {
  // 100–200+ methods
};

Size comparison

Client Lines Import sites Exported methods (est.)
lib/accounting-api.ts 1,856 30 200+
lib/beauty-business-api.ts 1,446 28 150+
lib/healthcare-api.ts 1,322 14 120+
lib/api.ts (platform) 502 ~15 40+

Duplication within API layer

Each monolith reimplements:

  • Token refresh on 401
  • x-tenant-id header injection
  • Error class with status code
  • JSON parse/error handling
  • Query string building

Estimated duplicated code: ~80 lines × 3 = ~240 lines of identical fetch wrapper logic.

Superseded / dead API files

File Lines Imports Status
lib/api-client.ts 62 0 Dead — duplicate of lib/api.ts
lib/optional-sso.ts ~50 0 Dead — SSO helpers never wired
lib/beauty-business-nav.ts ~100 0 Dead — superseded by lib/beauty-portals.ts

4. Platform API Dependencies

Direct backend calls (no BFF)

Client Target Used by
lib/api.ts NEXT_PUBLIC_BACKEND_URL (:8000) Admin, dashboard, onboarding
lib/identity.ts NEXT_PUBLIC_IDENTITY_API_URL (:8001) Auth flows
lib/auth.ts Keycloak + identity All authenticated modules

BFF-proxied calls

Client BFF route Upstream
lib/accounting-api.ts /api/accounting/* :8002
lib/beauty-business-api.ts /api/beauty-business/* :8011
lib/healthcare-api.ts /api/healthcare/* :8010

Missing BFF routes

Backend service Frontend client Gap
Delivery None No frontend module
Communication None Not implemented
Core (admin) Direct call CORS risk in some deployments

5. Hook Dependencies

Hook Depends on Depended on by
useMe lib/api.ts, TanStack Query useTenantId, useAuth, all portal layouts
useTenantId useMe ~67 component/page files
useAuth lib/auth.ts Auth pages, guards
useTheme lib/theme.ts ThemeProvider
useBeautyLookups beauty-business-api Beauty owner CRUD pages
useHealthcareLookups healthcare-api Healthcare portal pages
useHealthcarePatientContext healthcare-api, useMe Patient portal
useHealthcareDoctorContext healthcare-api, useMe Doctor portal
useHeaderSession useMe SiteHeader
useTenantHost lib/api.ts Platform home

No hook imports from wrong domain API client. ✅

6. Dead Code Inventory

Confirmed dead files (zero imports)

File Lines Reason
lib/api-client.ts 62 Superseded by lib/api.ts
lib/optional-sso.ts ~50 SSO flow never integrated
lib/beauty-business-nav.ts ~100 Superseded by lib/beauty-portals.ts
components/HealthStatus.tsx ~80 Component never mounted
components/beauty/pages/mobile.tsx ~60 MobilePortalFrame unused

Total dead code: ~350 lines across 5 files

Likely-unused exports (requires ts-prune)

The three API monoliths export hundreds of methods and types. Many correspond to routes not yet wired or features in development. Static analysis without runtime profiling cannot enumerate all unused exports.

High-confidence unused npm packages: 2
High-confidence dead files: 5
Estimated unused API exports: Unknown (likely 20–40% of monolith surface)

Deprecated but present

File Marker Imports
components/beauty/BeautyBusinessShell.tsx @deprecated comment 0 (verify)

7. Cross-Module Dependency Matrix

platform lib accounting lib beauty lib healthcare lib
platform lib ✅ ❌ ❌ ❌
accounting lib ✅ ✅ ❌ ❌
beauty lib ✅ ❌ ✅ ❌
healthcare lib ✅ ❌ ❌ ✅

Cross-module component imports: 0
Cross-module hook imports: 0
Circular dependencies: 0

8. Environment Variable Dependencies

From next.config.mjs:

Variable Default Consumer
NEXT_PUBLIC_BACKEND_URL localhost:8000 lib/api.ts
NEXT_PUBLIC_API_BASE_URL localhost:8000 Legacy alias
NEXT_PUBLIC_IDENTITY_API_URL localhost:8001 lib/identity.ts
NEXT_PUBLIC_KEYCLOAK_URL localhost:8080 lib/auth.ts
NEXT_PUBLIC_KEYCLOAK_REALM superapp lib/auth.ts
NEXT_PUBLIC_KEYCLOAK_CLIENT_ID superapp-frontend lib/auth.ts
NEXT_PUBLIC_ACCOUNTING_API_URL localhost:8002 accounting-api SSR
NEXT_PUBLIC_HEALTHCARE_API_URL localhost:8010 healthcare-api SSR

Missing from next.config.mjs env block:

  • NEXT_PUBLIC_BEAUTY_BUSINESS_API_URL (used in beauty-business-api.ts via process.env directly)
  • BEAUTY_BUSINESS_SERVICE_URL (BFF server-side)
  • ACCOUNTING_SERVICE_URL (BFF server-side)
  • HEALTHCARE_SERVICE_URL (BFF server-side)

9. Build Dependency Health

Check Result
npm run build compile ✅ ~55s
TypeScript check ❌ Fails (Button loading prop)
ESLint Not reached
Circular deps ✅ None
Unused npm (confirmed) ⚠️ 2 packages

10. Recommendations

Immediate (Phase 0)

  1. Remove @tanstack/react-table and recharts OR implement usage
  2. Delete 5 confirmed dead files
  3. Fix Button type error to unblock build

Short-term (Phase 3)

  1. Extract shared createApiClient() from three monoliths
  2. Split API clients by domain subdomain
  3. Run ts-prune to identify unused exports

Medium-term

  1. Add @next/bundle-analyzer to CI
  2. Add depcheck to CI for npm hygiene
  3. Add import graph validation script
