CLI Tool Built (v0.1.0)

Location: packages/mobile-ui/cli/

Commands:

• ✅ list - Show all components with install status
• ✅ add <component> - Copy component with automatic dependency resolution

Features:

• ✅ Automatic dependency resolution - Recursively installs all dependencies
• ✅ Conflict detection - Asks before overwriting existing components
• ✅ Skip installed - Doesn't reinstall already-present dependencies
• ✅ Beautiful UI - Colors, spinners, prompts for great UX
• ✅ Path auto-detection - Finds components/ directory automatically
• ✅ Full TypeScript - Type-safe implementation

Technical Stack:

• TypeScript 5.3
• Commander 11.1 (CLI framework)
• Chalk 4.1 (terminal colors)
• Ora 5.4 (spinners)
• Prompts 2.4 (interactive prompts)
• fs-extra 11.2 (file operations)

Example Usage:

# List all components
node packages/mobile-ui/cli/bin/cli.js list

# Add a component
node packages/mobile-ui/cli/bin/cli.js add button

# Output:
# ✔ Found component: Button
# ✔ Dependencies: icon, text
# ✔ Installed Icon
# ✔ Installed Text
# ✔ Installed Button
#
# ✅ Success!
# Files added: components/ui/Button/...
# Import: import { Button } from '@/components/ui/Button';

Documentation Created

Per Component (17 files):

• README.md - Usage examples, props table, variants, common patterns
• index.ts - Clean exports
• TypeScript types exported

Project Level:

• README.md - Main documentation, quick start guide
• STATUS.md - Detailed progress tracking
• CLI.md - Complete CLI documentation
• SUMMARY.md - This file
• registry.json - Component metadata with dependencies

Total Documentation: ~5000+ lines across 20+ markdown files

Architecture & Design Decisions

1. Copy-Paste Approach (shadcn-style)

   • Components are copied into apps, not installed as npm dependencies
   • Apps own the code and can customize freely
   • No version lock-in, updates are opt-in

2. No Theme Context

   • Removed all useTheme() dependencies
   • Hardcoded default colors with override props
   • Makes components portable and framework-agnostic

3. TypeScript First

   • All components fully typed
   • Exported types for all props
   • Generic support where needed (ToggleGroup, etc.)

4. Dependency Resolution

   • CLI automatically resolves and installs dependencies
   • Prevents missing imports
   • Installs in correct order (dependencies first)

5. Monorepo Structure

   • Embedded in picture app for now
   • Can be extracted to separate repo later
   • Uses pnpm workspaces

Testing Completed

✅ CLI Testing:

• Tested in /tmp/test-memoro-ui
• list command shows all 17 components correctly
• add command with dependency resolution works perfectly
• Navigation components (Header) tested successfully
• Installed status tracking works

✅ Component Testing:

• All components have working implementations
• No TypeScript errors
• All dependencies resolved correctly

🎯 What's Next

Immediate (Phase 4: Testing)

1. Test in Picture App

# From picture app root
node packages/mobile-ui/cli/bin/cli.js add header
node packages/mobile-ui/cli/bin/cli.js add button

# Replace existing implementations
# Test in real screens
# Document issues

Goals:

• Verify imports work correctly
• Test TypeScript types
• Check functionality on iOS/Android/Web
• Document any edge cases or problems

2. Real-World Usage

• Use components in actual features
• Replace old implementations gradually
• Test edge cases
• Performance testing

3. Document Learnings

• What works well?
• What needs improvement?
• Missing features?
• Common patterns discovered?

Short-Term (Phase 4: Extraction)

4. Test in Second App

• Pick another memoro project
• Use CLI to add components
• Validate portability
• Ensure components work outside picture app

5. Extract to Separate Repo

# 1. Create github.com/memoro/ui
# 2. Move packages/mobile-ui/ to new repo
# 3. Update all documentation
# 4. Set up GitHub Actions
# 5. Create README with installation instructions

6. Publish to GitHub Packages

# Configure package.json
{
  "name": "@memoro/ui",
  "repository": "https://github.com/memoro/ui",
  "publishConfig": {
    "registry": "https://npm.pkg.github.com"
  }
}

# Publish first version
npm publish

# Then in apps:
npx @memoro/ui add button

Medium-Term (Optional Enhancements)

7. CLI Improvements (If Needed)

• update <component> - Update with diff view
• diff <component> - Show differences
• init - Create directory structure
• remove <component> - Remove component

8. More Components (As Needed)

• Input/TextInput
• Switch/Toggle
• Checkbox
• Modal/Sheet
• Dropdown/Menu
• Avatar
• Divider
• Progress Bar
• Tabs
• Accordion

9. Tooling (Nice to Have)

• VSCode extension with snippets
• GitHub Actions for CI/CD
• Automated tests
• Storybook/Preview app
• Screenshot tests

Long-Term (Phase 2: Design System)

10. Design Tokens (If Patterns Emerge)

• Extract common colors/spacing
• Create @memoro/tailwind-preset package
• Refactor components to use tokens
• Centralize design decisions
• Theme variants (dark mode, brand colors)

---

✅ Success Criteria

Phase 4 Complete When:

• ✅ Components work perfectly in picture app
• ✅ Components work in second app
• ✅ CLI published to GitHub Packages
• ✅ Documentation is comprehensive
• ✅ No critical bugs

Overall Success When:

• ✅ Used in 2+ production apps
• ✅ Component reuse rate >60%
• ✅ Time to build features reduced by ~30%
• ✅ UI consistency across all apps
• ✅ Developers love using it
• ✅ Easy onboarding for new developers

📝 Key Learnings

What Worked Well:

1. CLI-first approach - Having the tool ready made testing easy
2. Copy-paste philosophy - No npm dependencies = full control
3. Comprehensive READMEs - Examples make adoption easy
4. TypeScript types - Catch errors early
5. Automatic dependencies - Just works, no manual tracking

Architecture Strengths:

1. Portable components - No theme context = works anywhere
2. Prop-based customization - Color props allow flexibility
3. Dependency resolution - CLI handles complexity
4. Monorepo structure - Easy to develop and test

Future Considerations:

1. Theme system - May need shared theme later
2. More components - Input fields, forms, modals
3. Testing strategy - Consider automated tests
4. Preview app - Might be useful for showcasing
