Component Consolidation Guide

Overview

This guide consolidates 55+ duplicated components into 12 unified modules. Target: 50% code reduction in components directory.

---

Priority 1: High-Duplication Components

1. Communication System

Current State:

• communication-view.tsx (800 lines)
• parent-communication-view.tsx (900 lines)
• Total: 1,700 lines of 85% similar code

Consolidated Solution:

• ✅ Created unified-communication.tsx (wrapper)
• Uses unified-nav-menu for role-based filtering
• Both views now auto-select based on user role

Migration Path:

1. Update imports in parent pages to use UnifiedCommunication
2. Keep both views as internal implementations
3. Remove direct imports from pages

---

2. Navigation System

Current State:

• Multiple navigation implementations
• Duplicated menu building logic
• Inconsistent route references

Consolidated Solution:

• ✅ Created navigation-config.ts (centralized config)
• ✅ Created unified-nav-menu.tsx (single component)
• Single source of truth for all routes

Benefits:

• Change route once, updates everywhere
• Role-based filtering in one place
• Compliance gates centralized (Module L)

Action Items:

// OLD: Multiple nav implementations
import { TeacherNav } from './teacher-nav'
import { StudentNav } from './student-nav'
import { ParentNav } from './parent-nav'

// NEW: Single unified nav
import { UnifiedNavMenu } from '@/components/unified-nav-menu'

<UnifiedNavMenu orientation="vertical" />

---

3. Data Tables (8 implementations)

Current State:

• analytics-table.tsx
• attendance-table.tsx
• grades-table.tsx
• behavior-table.tsx
• assessments-table.tsx
• competitors-table.tsx
• notebook-table.tsx
• messages-table.tsx

Problem: 85% identical code, only differs in columns/data

Consolidated Solution:

• Already created: data-table.tsx (reusable)
• Configure via column definitions, not code duplication

Implementation:

// Define columns once
const gradesColumns: ColumnDef<Grade>[] = [
  { accessorKey: 'subject', header: 'Subject' },
  { accessorKey: 'grade', header: 'Grade' },
  // ... more columns
];

// Use generic table
<DataTable
  columns={gradesColumns}
  data={grades}
  onSort={handleSort}
  onFilter={handleFilter}
  actionButtons={[/* actions */]}
/>

Consolidation Checklist:

• Extract column definitions to separate files
• Replace all 8 table components with DataTable
• Verify sorting, filtering, pagination work
• Delete original 8 files
• Expected saving: ~3,000 lines

---

4. Forms (10+ implementations)

Current State:

• student-form.tsx
• grade-entry-form.tsx
• assessment-creation-form.tsx
• behavior-incident-form.tsx
• wellness-check-form.tsx
• message-compose-form.tsx
• notebook-form.tsx
• And more duplicates

Consolidated Solution:

• Already created: form-builder.tsx (schema-driven)

Implementation:

// Define schema once
const gradeSchema = z.object({
  subject: z.string(),
  grade: z.number().min(1).max(6),
  comment: z.string().optional(),
});

// Use generic builder
<FormBuilder
  schema={gradeSchema}
  onSubmit={handleSubmit}
  fields={['subject', 'grade', 'comment']}
/>

Consolidation Checklist:

• Extract form schemas to schemas/forms/
• Replace all 10+ forms with FormBuilder
• Test validation on all forms
• Delete original files
• Expected saving: ~4,000 lines

---

5. Analytics & Charts (4 implementations)

Current State:

• grade-analytics-view.tsx (600 lines)
• attendance-analytics.tsx (500 lines)
• behavior-analytics.tsx (550 lines)
• competency-analytics.tsx (480 lines)

Problem: Same charting logic, different data sources

Consolidated Solution:

// Centralized chart configs
const chartConfigs = {
  GRADES: { type: 'bar', color: 'emerald', metrics: ['grade', 'trend'] },
  ATTENDANCE: { type: 'line', color: 'blue', metrics: ['present', 'absent'] },
  BEHAVIOR: { type: 'area', color: 'red', metrics: ['incidents', 'warnings'] },
};

// Generic analytics component
<AnalyticsPanel
  type="GRADES"
  data={gradesData}
  config={chartConfigs.GRADES}
/>

Expected saving: ~2,000 lines

---

Priority 2: Medium-Duplication Components

6. Dashboard Widgets (4 variations)

Consolidation: Use widget-container.tsx + dashboard-customizer.tsx

7. Modal/Dialog Components (6+ duplicates)

Consolidation: Use confirm-dialog.tsx for confirmations

8. Status Badges (5+ implementations)

Consolidation: Create centralized status-badge.tsx

---

Priority 3: API & Data Patterns

9. API Hooks (60+ manual fetch patterns)

Solution: Use useApi() hook everywhere

Migration:

// OLD
const [data, setData] = useState([]);
useEffect(() => {
  fetch('/api/grades').then(r => r.json()).then(setData);
}, []);

// NEW
const { data } = useApi('/api/grades', { revalidateOnFocus: true });

10. Response Handling (100+ duplicated patterns)

Solution: Use api-response.ts wrapper

---

Expected Results After Consolidation

Metric	Before	After	Reduction
Component files	55	12	78%
Total LOC	~18,000	~9,000	50%
Form code	4,000	400	90%
Table code	3,000	300	90%
Navigation LOC	2,000	300	85%
API calls	60+ patterns	1 hook	99%
Bundle size	450KB	300KB	33%
Bundle (gzip)	120KB	75KB	37%
