📋 Daily Codebase Review - 2026-02-04

[claude]

Executive Summary

The Sobers codebase demonstrates strong overall health with well-structured architecture, comprehensive security measures, and good test coverage. The project follows consistent patterns across components and has robust PII protection mechanisms in place. A few minor improvements are recommended.

Health Score: A-

Justification: The codebase exhibits:

• Clean architecture with clear separation of concerns
• Strong security practices with PII scrubbing in Sentry and analytics
• Good test coverage (40 of 42 component files have tests)
• Consistent coding patterns and import conventions
• Modern React patterns (hooks, memoization)
• Well-documented code with JSDoc comments

Minor deductions for:

• A few missing component tests (2 files)
• One skipped TODO in test file
• Large SettingsContent component (2k+ lines)

Top 5 Priority Items

1. Add missing tests for navigation components (LOW)

   • SettingsButton.tsx and TabBarBackground.tsx need test coverage
   • Files: components/navigation/SettingsButton.tsx, components/navigation/TabBarBackground.tsx

2. Fix meetings test TODO (LOW)

   • __tests__/app/program/meetings.test.tsx:105 has a TODO to fix mock setup
   • Tests are skipped due to unmounted component issues

3. Consider splitting SettingsContent (LOW)

   • components/settings/SettingsContent.tsx is 2089 lines
   • Could be split into smaller section components for maintainability

4. Keep dependencies up to date (INFO)

   • Dependencies appear reasonably current
   • Recommend periodic pnpm outdated checks

5. Continue expanding E2E test coverage (INFO)

   • E2E infrastructure is in place with Playwright
   • Coverage could be expanded for critical user flows

Detailed Findings by Category

1. Code Health & Technical Debt ✅

Findings:

• TODO/FIXME Comments: Only 1 found in test file (__tests__/app/program/meetings.test.tsx:105)
• Code Complexity: SettingsContent.tsx is large (2089 lines) but well-organized with clear sections
• Deprecated Patterns: None found
• Duplicated Code: Minimal - good use of shared utilities and components

2. Security Audit ✅

Findings:

• No hardcoded secrets detected in source files
• Strong PII protection:
  • lib/sentry-privacy.ts: Comprehensive scrubbing of sensitive fields (email, tokens, passwords, sobriety dates)
  • lib/analytics-utils.ts: PII stripping for analytics events
• Secure storage: Uses expo-secure-store with chunking for large tokens
• OAuth handling: Proper token extraction and session management
• Input validation: lib/validation.ts provides password and display name validation
• No SQL injection risks: Uses Supabase SDK with parameterized queries
• No eval/dangerouslySetInnerHTML usage

3. Test Coverage Gaps ⚠️

Findings:

• Components: 40 of 42 files have tests (95% file coverage)
• Missing tests:
  • components/navigation/SettingsButton.tsx
  • components/navigation/TabBarBackground.tsx (has test but may be different component)
• Skipped tests:
  • meetings.test.tsx has TODO noting mock setup issues

4. Documentation Freshness ✅

Findings:

• README.md: Accurate and up-to-date
• CLAUDE.md: Comprehensive development guide with current patterns
• CHANGELOG.md: Well-maintained with [Unreleased] section for new Program features
• JSDoc: Good coverage on public APIs and complex functions
• Architecture docs: docs/ folder contains OAuth setup guides and logger documentation

5. Dependency Health ✅

Findings:

• Using Expo 54, React Native 0.81, React 19 - modern stack
• TypeScript 5.9 in strict mode
• All major dependencies appear well-maintained
• Has pnpm.overrides for @react-native-async-storage/async-storage resolution

6. Performance Opportunities ✅

Findings:

• Good memoization: 127 uses of useMemo/useCallback/React.memo across 30 component files
• Style optimization: Uses createStyles pattern with theme for memoized styles
• Lazy loading: Analytics initialized via dynamic import
• Efficient data fetching: Supabase queries use appropriate limits and ordering

7. Consistency Check ✅

Findings:

• Import conventions: Consistent use of @/ path alias (115 occurrences in components)
• Only 2 relative imports: Both in settings for package.json version access (acceptable)
• Naming conventions: PascalCase for components, camelCase for functions
• Code organization: Follows Imports → Types → Constants → Helpers → Component → Styles pattern
• ESLint enforcement: no-console rule with appropriate exceptions
