Detailed Findings

🚨 CRITICAL (3 issues)

1. Tokens stored in localStorage (Security)

Current State: Authentication tokens stored in localStorage in 3 files Target State: Use HttpOnly cookies for JWT storage

Files Affected:

• src/utils/auth.ts
• src/hooks/useAuth.ts
• src/api/client.ts

Impact: localStorage is vulnerable to XSS attacks. If attacker injects JavaScript, they can steal authentication tokens.

Migration Steps:

1. Configure API backend to set JWT in HttpOnly cookie
2. Remove localStorage.setItem('token', ...) calls
3. Use credentials: 'include' in fetch requests
4. Implement CSRF protection
5. Test authentication flow

Effort: MEDIUM

---

2. No features/ directory - flat structure (Structure)

Current State: All 287 files in flat src/ directory structure Target State: 80%+ code organized in feature-based modules

Impact:

• Difficult to scale beyond current size
• No clear feature boundaries
• High coupling between unrelated code
• Difficult to test in isolation
• New developers struggle to find code

Migration Steps:

1. Create src/features/ directory
2. Identify distinct features (e.g., authentication, dashboard, profile, settings)
3. Create directories for each feature
4. Move feature-specific code to respective features/
5. Organize each feature with api/, components/, hooks/, stores/ subdirectories
6. Update all import paths
7. Test thoroughly after each feature migration

Effort: HIGH (plan for 2 weeks)

---

3. No testing framework detected (Testing)

Current State: Jest found but no @testing-library/react Target State: Use Testing Library for user-centric React testing

Impact:

• Testing components requires low-level implementation testing
• Tests are brittle and break on refactoring
• Cannot follow testing trophy distribution
• Poor test quality

Migration Steps:

1. Install @testing-library/react
2. Install @testing-library/jest-dom
3. Configure test setup file
4. Write example tests using Testing Library patterns
5. Train team on Testing Library principles

Effort: LOW

---

⚠️ HIGH (12 issues - showing top 5)

4. No data fetching library (State Management)

Current State: Manual API state management with Redux Target State: Use React Query or SWR for server cache state

Migration Steps:

1. Install @tanstack/react-query
2. Wrap app with QueryClientProvider
3. Convert Redux API slices to React Query hooks
4. Remove manual loading/error state management
5. Configure caching strategies

Effort: MEDIUM

---

5. Test coverage at 65.3% (Testing)

Current State: Line coverage: 65.3%, Branch coverage: 58.2% Target State: Maintain 80%+ test coverage

Critical Untested Paths:

• Authentication flow
• Payment processing
• User profile updates

Migration Steps:

1. Generate coverage report with uncovered files
2. Prioritize critical paths (authentication, payments)
3. Write integration tests first (70% of tests)
4. Add unit tests for business logic
5. Configure coverage thresholds in jest.config.js

Effort: HIGH

---

6. Large component: UserDashboard.tsx (468 LOC) (Components)

Current State: src/components/UserDashboard.tsx has 468 lines Target State: Components should be < 300 lines

Migration Steps:

1. Identify distinct UI sections in dashboard
2. Extract sections to separate components (DashboardHeader, DashboardStats, DashboardActivity)
3. Move business logic to custom hooks (useDashboardData)
4. Extract complex calculations to utility functions
5. Update tests to test new components independently

Effort: MEDIUM

---

7. Cross-feature imports detected (Structure)

Current State: 8 files import from other features Violations:

• features/dashboard → features/profile
• features/settings → features/authentication

Target State: Features should be independent. Shared code belongs in src/components/ or src/utils/

Migration Steps:

1. Identify shared code being imported across features
2. Move truly shared components to src/components/
3. Move shared utilities to src/utils/
4. If code is feature-specific, duplicate it or refactor feature boundaries

Effort: MEDIUM

---

8. No error boundaries detected (Error Handling)

Current State: No ErrorBoundary components found Target State: Multiple error boundaries at route and feature levels

Migration Steps:

1. Create src/components/ErrorBoundary.tsx
2. Wrap each route with ErrorBoundary
3. Add feature-level error boundaries
4. Display user-friendly error messages
5. Log errors to Sentry

Effort: LOW

---

📊 MEDIUM (24 issues - showing top 3)

9. Too many shared components (Structure)

Current State: 62.3% of components in src/components/ (shared) Target State: Most components should be feature-specific

Migration Steps:

1. Review each shared component
2. Identify components used by only one feature
3. Move feature-specific components to their features
4. Keep only truly shared components in src/components/

Effort: MEDIUM

---

10. Component with 12 props: UserProfileForm (Components)

Current State: UserProfileForm accepts 12 props Target State: Components should accept < 7-10 props

Migration Steps:

1. Group related props into configuration object
2. Use composition (children) instead of render props
3. Extract sub-components with their own props
4. Consider Context for deeply shared state

Effort: LOW

---

11. No code splitting detected (Performance)

Current State: No React.lazy() usage found Target State: Use code splitting for routes and large components

Migration Steps:

1. Wrap route components with React.lazy()
2. Add Suspense boundaries with loading states
3. Split large features into separate chunks
4. Analyze bundle size with vite-bundle-analyzer

Effort: LOW

---

Recommendations

Immediate Action Required (This Week)

1. Security: Move tokens from localStorage to HttpOnly cookies
2. Structure: Create features/ directory and plan migration
3. Testing: Install Testing Library and write example tests

This Sprint (Next 2 Weeks)

4. Structure: Begin feature extraction (start with 1-2 features)
5. State: Add React Query for API calls
6. Testing: Increase coverage to 70%+
7. Components: Refactor largest components (> 400 LOC)
8. Errors: Add error boundaries

Next Quarter (3 Months)

9. Structure: Complete feature-based migration
10. Testing: Achieve 80%+ coverage
11. Performance: Implement code splitting
12. State: Evaluate Redux necessity (might not need with React Query)

Backlog

13. Standards: Add git hooks (Husky) for pre-commit checks
14. Components: Improve component colocation
15. Styling: Document design system
16. Naming: Enforce kebab-case file naming
