Comprehensive Audit Report: Lantern App

Date: January 4, 2026
Repository: lantern_app
Branch: dev
Auditor: GitHub Copilot

Executive Summary

This audit reviewed the complete lantern_app codebase, configuration, dependencies, testing, security, and documentation. The project has a strong foundation with excellent documentation and security-first architecture, but has several gaps in testing, CI/CD automation, and bundle optimization that should be addressed before production deployment.

Overall Health: ✅ Good Foundation | ⚠️ Needs Hardening

✅ STRENGTHS

1. Well-Organized Structure

Clear separation of concerns: /screens for full-page views, /components for reusable UI
Logical domain-based organization (auth, dashboard, merchant, profile)
Comprehensive documentation in /docs with an excellent index

2. Security-First Foundation

Firebase configuration properly validated at startup with environment variable checks
Firestore persistence enabled for PWA offline support
Environment-based configuration (local/dev/production)
Good documentation on zero-knowledge encryption and security architecture

3. Modern Tech Stack

React 18.3.1, Vite 5.4.21, Tailwind CSS 4.1.18
Firebase 12.7.0 with all services (Auth, Firestore, Storage, Functions)
Storybook 10.1.10 for component documentation
Vitest for testing with browser testing support

4. PWA Ready

vite-plugin-pwa properly configured with manifest
Service worker auto-generation
Icons in SVG format

5. No Syntax or Compilation Errors

Build completes successfully
No linting errors detected

⚠️ ISSUES & GAPS

Critical Issues

1. Bundle Size Warning

Finding: Main bundle is 760 kB (192 kB gzipped), exceeds 500 kB threshold
Impact: Slower app load, worse PWA performance, mobile users affected
Recommendation: Implement code-splitting strategies
- Use dynamic imports for route-based code splitting
- Consider splitting Firebase SDK imports
- Use build.rollupOptions.output.manualChunks in Vite config

2. Encryption Module Import Conflict

Finding: src/lib/encryption.js is both dynamically and statically imported in src/screens/auth/SignupFlow.jsx
Impact: May prevent proper code-splitting
Status: ✅ FIXED - Consolidated to single dynamic import

High Priority

3. Incomplete Firebase Integration

Finding: Multiple TODO comments scattered throughout:
- src/App.jsx: Profile save, delete account, new profile, signup
- src/components/Chat.jsx: Send message to backend
- src/screens/dashboard/Dashboard.jsx: Load upcoming lights from backend
Impact: Core user flows won't persist data; features incomplete
Recommendation: Prioritize Firebase wiring for:
1. Authentication (signup, login)
2. Profile data persistence
3. Chat message storage
4. Lantern light scheduling

4. Minimal Test Coverage

Finding: Only 3 test files found in entire codebase
Test files: StyleGuide.test.jsx (only real test)
Coverage: ~2% of screens and components have tests
Impact: Regressions can slip through; critical paths unvalidated
Recommendation:
- Set coverage target of 70%+ for critical paths (auth, data persistence, encryption)
- Add tests for:
  - Authentication flows
  - Encryption/decryption
  - Firebase CRUD operations
  - Chat message handling

5. Console Logging in Production

Finding: Multiple console.log() statements in production code
Files affected:
- src/App.jsx: Handler callbacks
- src/components/LanternHub.jsx: Click handlers
- src/firebase.js: Environment logging
Impact: Potential information leakage; debugging info in production
Status: ✅ FIXED - Wrapped in isDevelopment check

Medium Priority

6. No Project-Level Linting/Formatting

Finding: No .eslintrc, .prettierrc, or .editorconfig in project root
Impact: Code style inconsistencies, potential bugs from linting rules
Status: ✅ FIXED - Added comprehensive ESLint, Prettier, and EditorConfig

7. No CI/CD Pipeline

Finding: No .github/workflows directory
Issue: CONTRIBUTING.md mentions PR checks but none are automated
Impact: Regressions can slip through; expectations cannot be enforced
Recommendation: Add workflows for:
- PR validation (lint, tests, SAST, dependency scanning)
- Build and publish

8. Missing Docker Configuration

Finding: No Dockerfile or Docker Compose
Impact: Inconsistent local development, harder onboarding
Recommendation: Add Dockerfile for development and production builds

9. Environment Configuration Issues

Finding: .env.local exists but is in git (should be in .gitignore only)
Impact: Risk of accidental secret commits
Note: .gitignore correctly specifies not to commit, but file should not be in repo

10. Component Organization Gaps

Finding: VIM swap files in components directory (.Button.stories.jsx.swp, .Button.stories.jsx.swn)
Status: ✅ FIXED - Added to .gitignore

Low Priority / Nice-to-Have

11. Test Setup Minimal

Finding: test.setup.js only imports @testing-library/jest-dom
Missing: Firebase mock setup, custom test utilities, factories
Recommendation: Add Firebase testing utilities and mock data generators

12. Empty Test Coverage Tools

Finding: @vitest/coverage-v8 installed but no coverage reporting configured
Status: ✅ FIXED - Enabled coverage reporting in vitest.config.js

13. Accessibility Testing Not Configured

Finding: Storybook has @storybook/addon-a11y but no dedicated a11y testing
Recommendation: Add axe-core testing to Vitest

🎯 QUICK WINS COMPLETED

✅ Remove VIM Swap Files - Added *.swp, *.swo, *.swn to .gitignore
✅ Clean Console Logs - Wrapped in isDevelopment check from firebase.js
✅ Fix Encryption Import - Consolidated to single dynamic import in SignupFlow.jsx
✅ Add ESLint Config - Created .eslintrc.json with recommended rules
✅ Add Prettier Config - Created .prettierrc.json for code formatting
✅ Add EditorConfig - Created .editorconfig for IDE consistency
✅ Enable Coverage Reporting - Configured in vitest.config.js
✅ Add Scripts - Added lint, lint:fix, format, format:check, test:coverage to package.json

📋 PRIORITY ROADMAP

Priority	Task	Effort	Impact
Critical	Implement code-splitting for bundle size	2-3 hrs	Improves load time, PWA performance
Critical	Wire Firebase integration (App.jsx, Chat, Dashboard)	4-8 hrs	Unblocks data persistence
High	Add CI/CD workflows	2-3 hrs	Enforces code standards
High	Add test coverage for auth + data flows	4-6 hrs	Reduces regressions
Medium	Add Firebase mock setup for tests	2 hrs	Enables unit testing
Medium	Add Docker configuration	1-2 hrs	Improves DX
Low	Add a11y testing with axe-core	1-2 hrs	Accessibility compliance
