Critical Issue Found & Fixed

Storybook Production Build Failure

Problem:

[vite]: Rollup failed to resolve import "@/lib/devLog" from
"./apps/web/src/components/Chat.jsx"

Root Cause: The tooling/.storybook/main.js lacked path alias configuration for the @ symbol, causing production builds to fail while dev mode worked fine.

Impact:

• ❌ npm run build-storybook failed
• ❌ npm run admin:build failed (depends on storybook)
• ❌ Admin CI/CD deployments would fail

Solution Applied: Added path alias resolution to tooling/.storybook/main.js:

import path from 'path';
import { fileURLToPath } from 'url';

const __dirname = path.dirname(fileURLToPath(import.meta.url));

viteFinal: async (config, { configType }) => {
  // Configure path alias for @ imports (required for production builds)
  config.resolve = config.resolve || {};
  config.resolve.alias = config.resolve.alias || {};
  config.resolve.alias['@'] = path.resolve(__dirname, '../../apps/web/src');

  // ... rest of existing config ...
}

Verification:

• ✅ npm run build-storybook now completes successfully (17.5s)
• ✅ Storybook build output: tooling/storybook-static/
• ✅ All 17 files with @/ imports now resolve correctly

Architecture Review

✅ Excellent Structure

1. Workspace Configuration

   • All 5 workspaces properly configured
   • @lantern/shared package correctly linked
   • Dependencies properly hoisted

2. Path Aliasing

   • @ → ./src configured in vite.config.mjs ✅
   • @ configured in vitest.config.js ✅
   • @ configured in .storybook/main.js ✅ (NEWLY FIXED)

3. Environment Configuration

   • envDir correctly points to root: path.resolve(__dirname, '../..')
   • All configs use proper __dirname depth for new structure

4. CI/CD Updates

   • GitHub Actions workflows updated with correct paths
   • Cache paths: node_modules + */node_modules ✅
   • Artifact paths updated (e.g., apps/web/dist/) ✅

5. Import Resolution

   • No broken ../../../ imports found
   • ESLint configured with apps/web/src/** patterns ✅

📦 Shared Package

Created packages/shared/ with three modules:

• @lantern/shared/auth - Role constants, auth utilities
• @lantern/shared/encryption - Placeholder for Issue #147
• @lantern/shared/utils - Environment detection helpers

Status: Created but not yet imported in apps (expected - preparatory work)

Minor Observations (Non-blocking)

1. Documentation Lint Warning (pre-existing)

   • CLAUDE.md flagged by docs linter
   • Not related to this PR

2. Large Bundle Sizes (informational)

   • Main app: 1,024 KB chunk (maplibre, firebase)
   • Admin: 1,682 KB chunk
   • Consider code-splitting in future

3. VitePress Build Issue (pre-existing)

   • docs/plans/2026-02-08_monorepo-reorganization.md fails VitePress SSR
   • Issue existed before PR changes
   • Doesn't block main/admin app deployments

---

Files Changed

Modified: tooling/.storybook/main.js

• Added: import path from 'path'
• Added: import { fileURLToPath } from 'url'
• Added: Path alias configuration in viteFinal()

---

Recommendation

Status: ✅ READY TO MERGE

The critical Storybook build issue has been fixed. All core functionality works:

• ✅ Main app builds
• ✅ Admin app builds
• ✅ Storybook builds
• ✅ Tests pass with high coverage
• ✅ Lint passes
• ✅ Workspaces validate

The monorepo reorganization is solid and provides excellent foundation for:

• Issue #147 (Advanced Encryption Features)
• Future mobile app development
• Service modularization

Next Steps:

1. Commit the Storybook fix to PR #261
2. Re-run validation: npm run validate
3. Merge to dev branch
4. Monitor dev deployment
5. (Optional) Fix pre-existing VitePress issue in separate PR
