## 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

||||
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)

|
||||
### 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
|
||||
