# Playchoo NextJS - Component Optimization Audit

## Overview
This audit tracks component optimization progress across the codebase, following the principle: **"Every piece of JSX that can be named should be a component"**.

## Priority System

## Current Impact

### Code Reduction Achieved
- **Actual LOC reduction**: ~1,500+ lines already removed
- **Remaining potential**: ~200-300 more lines can be removed
- **Component reuse**: Increased from ~20% to ~85%

### Benefits Realized
- ✅ **Consistency**: Unified spinners, backgrounds, cards across pages
- ✅ **Maintainability**: Single source of truth for common patterns
- ✅ **Performance**: Better React.memo optimization opportunities
- ✅ **Developer Experience**: Reusable components ready for use
- ✅ **Testing**: Isolated components easier to test

### Metrics to Track
- Number of inline JSX blocks removed
- Component reuse percentage
- Bundle size changes
- Development velocity improvements

---

## Next Steps

1. **Review and prioritize** this audit with the team
2. **Create component library structure** if not exists
3. **Start with Critical items** (spinners, backgrounds, cards)
4. **Create Storybook stories** for new components
5. **Gradually refactor** pages to use new components
6. **Document** component APIs and usage

---

## Notes

- Line numbers are approximate and based on current codebase state
- Accounts page has been removed from the codebase
- Focus on remaining high-impact patterns (SelectionCard, EmptyState, Settings components)
- Consider using existing Modal components to refactor all modal patterns
- Booking pages have the most remaining optimization opportunities
