## New Components Required
|
||||
|
||||
### Atoms (Basic Elements)
|
||||
|
||||
#### StatBadge
|
||||
|
||||
**Purpose**: Small metric indicator with icon and optional pulse animation
|
||||
**Variants**: success, warning, error, info
|
||||
**States**: default, pulse (animated)
|
||||
**Similar to**: Badge (78% match)
|
||||
|
||||
**Recommendation**: Extend existing Badge component with `variant="stat"` prop instead of creating new component. Add icon prop and pulse animation state.
|
||||
|
||||
### Molecules (Simple Combinations)
|
||||
|
||||
#### TrendIndicator
|
||||
|
||||
**Purpose**: Show metric trend with arrow and percentage change
|
||||
**Composition**: Icon (arrow up/down) + Text (percentage) + StatBadge
|
||||
**Variants**: up (green), down (red), neutral (gray)
|
||||
**Similar to**: None (0% match)
|
||||
|
||||
**Recommendation**: Create new molecule component. Reuse StatBadge internally.
|
||||
|
||||
### Organisms (Complex Components)
|
||||
|
||||
#### DashboardGrid
|
||||
|
||||
**Purpose**: Responsive grid layout for dashboard widgets
|
||||
**Composition**: Grid container + flexible widget slots
|
||||
**Responsive**: 1 col (mobile), 2 col (tablet), 3 col (desktop)
|
||||
**Similar to**: None (0% match)
|
||||
|
||||
**Recommendation**: Create new organism component with responsive grid behavior. Use CSS Grid for layout.
|
||||

|

|
||||
## Component Reuse Opportunities
|
||||
|
||||
### StatBadge → Extend Badge
|
||||
|
||||
**Similarity**: 78%
|
||||
**Recommendation**: Extend existing Badge component with new variant instead of creating duplicate component
|
||||
**Time Saved**: 2-3 hours
|
||||
|
||||
**Approach**: Add `variant="stat"` option to Badge props. Add `icon` prop for optional icon display. Add `pulse` boolean prop for animation state. Maintains existing Badge API while adding new functionality.
|
||||
|
||||
### MetricCard → Enhance Existing
|
||||
|
||||
**Similarity**: 85%
|
||||
**Recommendation**: Add trend and comparison props to existing MetricCard component
|
||||
**Time Saved**: 2 hours
|
||||
|
||||
**Approach**: Add `trend` prop (up/down/neutral). Add `comparisonPeriod` prop (string). Both optional initially for backward compatibility. Mark as required in v3.0.0.

||||
## Design System Impact
|
||||
|
||||
### Token Health
|
||||
|
||||
- **In Sync**: 87 tokens
|
||||
- **Drift Detected**: 5 tokens
|
||||
- **Missing in Code**: 12 tokens
|
||||
- **Unused in Design**: 3 tokens
|
||||
|
||||
**Sync Status**: Drift Detected
|
||||
**Priority Level**: High
|
||||
|
||||
### High Impact Changes
|
||||
|
||||
- **Color primary.600 modification**
|
||||
- **Impact**: Breaking change for custom theme consumers
|
||||
- **Action Required**: Update documentation, notify users in changelog
|
||||
|
||||
- **Spacing.md increase** (16px → 20px)
|
||||
- **Impact**: Layout shifts in existing grid components
|
||||
- **Action Required**: Visual regression testing on all layouts
|
||||
|
||||
### Low Impact Changes
|
||||
|
||||
- Typography weight increase (400 → 500) - minimal visual change
|
||||
- New status colors - additive only, no conflicts
|
||||
- New widget tokens - isolated to dashboard feature
|
||||
|

|
||||
|
||||
## Implementation Recommendations
|
||||
|
||||
### Phased Approach
|
||||
|
||||
**Phase 1: Design Tokens** (2 hours)
|
||||
- Priority: High
|
||||
- Add 12 new tokens to design-tokens.json
|
||||
- Update 5 existing tokens
|
||||
- Run Style Dictionary build
|
||||
- Update Tailwind @theme
|
||||
|
||||
**Phase 2: Atomic Components** (3 hours)
|
||||
- Priority: High
|
||||
- Extend Badge component with stat variant (2h)
|
||||
- Add pulse animation to Badge (1h)
|
||||
|
||||
**Phase 3: Molecule Components** (2 hours)
|
||||
- Priority: Medium
|
||||
- Create TrendIndicator component (2h)
|
||||
|
||||
**Phase 4: Organism Components** (5 hours)
|
||||
- Priority: Medium
|
||||
- Create DashboardGrid component (3h)
|
||||
- Enhance MetricCard with trend props (2h)
|
||||
|
||||
### Total Estimated Time
|
||||
|
||||
**12 hours** (Medium complexity)
|
||||
|
||||

|
||||
|
||||
## Breaking Changes
|
||||
|
||||
### MetricCard
|
||||
|
||||
**Issue**: Adding required `trend` and `comparisonPeriod` props breaks existing usage
|
||||
**Previous Mapping**: `src/components/molecules/MetricCard.tsx` (8 existing usages)
|
||||
**Recommendation**: Add props as optional first, then require in major version
|
||||
|
||||
**Migration Steps**:
|
||||
- Add props as optional in v2.4.0
|
||||
- Add deprecation warning when props not provided
|
||||
- Update all 8 existing usages in codebase
|
||||
- Document migration in CHANGELOG.md
|
||||
- Make props required in v3.0.0 (breaking change)
|
||||
- Provide codemod script for automated migration
|
||||

|
||||
|
||||
## Next Steps
|
||||
|
||||
1. **Review Implementation Plan**: `.agent/tasks/TASK-16-dashboard-redesign.md`
|
||||
2. **Update Design Tokens**: Phase 1 implementation
|
||||
3. **Implement Components**: Follow atomic design hierarchy
|
||||
4. **Test & Verify**: Visual regression, accessibility, unit tests
|
||||
5. **Update UI Kit Inventory**: After each component completion
