# Complete Modular Architecture - Self-Contained Flows
## Overview
This architecture ensures that **each flow folder is completely self-contained**. Deleting a flow folder (e.g., `flows/dealer-claim/` or `flows/custom/`) removes **ALL** related code for that flow type. No dependencies remain outside the flow folder.
## Architecture Principles
1. **Complete Self-Containment**: Each flow folder contains ALL its related code
2. **Zero External Dependencies**: Flow folders don't depend on each other
3. **Single Point of Entry**: Main RequestDetail routes to flow-specific screens
4. **True Modularity**: Delete a folder = Remove all related functionality
## Directory Structure

```
## How It Works
### Main RequestDetail Router
The main `pages/RequestDetail/RequestDetail.tsx` is now a **simple router**:
```typescript
// 1. Fetches request to determine flow type
const flowType = getRequestFlowType(apiRequest);
// 2. Gets the appropriate RequestDetail screen from flow registry
const RequestDetailScreen = getRequestDetailScreen(flowType);
// 3. Renders the flow-specific screen
return <RequestDetailScreen {...props} />;
```
### Flow-Specific RequestDetail Screens
Each flow has its **own complete RequestDetail screen**:
- `flows/custom/pages/RequestDetail.tsx` - Complete custom request detail
- `flows/dealer-claim/pages/RequestDetail.tsx` - Complete dealer claim detail
Each screen:
- Uses its own flow-specific components
- Uses shared components from `flows/shared/`
- Is completely self-contained
- Can be deleted without affecting other flows
## Deleting a Flow Type
To completely remove a flow type (e.g., Dealer Claim):
### Step 1: Delete the Flow Folder
```bash
# Delete the entire folder
rm -rf src/flows/dealer-claim/
```
### Step 2: Update Flow Registry
```typescript
// src/flows/index.ts
export const FlowRegistry = {
CUSTOM: CustomFlow,
// DEALER_CLAIM removed - all code is gone!
} as const;
export function getRequestDetailScreen(flowType: RequestFlowType) {
switch (flowType) {
// case 'DEALER_CLAIM': removed
case 'CUSTOM':
default:
return CustomFlow.CustomRequestDetail;
}
}
```
### Step 3: Update Type Definitions (Optional)
```typescript
// src/utils/requestTypeUtils.ts
export type RequestFlowType = 'CUSTOM'; // 'DEALER_CLAIM' removed
```
**That's it!** All dealer claim related code is gone:
- ✅ RequestDetail screen deleted
- ✅ All components deleted
- ✅ All modals deleted
- ✅ All cards deleted
- ✅ All creation wizards deleted
- ✅ No orphaned code remains
## What's Inside Each Flow Folder
### Custom Flow (`flows/custom/`)
- ✅ Request Detail Screen (`pages/RequestDetail.tsx`)
- ✅ Request Detail Components (OverviewTab, WorkflowTab)
- ✅ Request Creation Component (CreateRequest)
- 🔜 Custom-specific hooks
- 🔜 Custom-specific services
- 🔜 Custom-specific utilities
- 🔜 Custom-specific types
### Dealer Claim Flow (`flows/dealer-claim/`)
- ✅ Request Detail Screen (`pages/RequestDetail.tsx`)
- ✅ Request Detail Components (OverviewTab, WorkflowTab, IOTab)
- ✅ Request Detail Cards (5 cards)
- ✅ Request Detail Modals (7 modals)
- ✅ Request Creation Component (ClaimManagementWizard)
- 🔜 Dealer claim-specific hooks
- 🔜 Dealer claim-specific services
- 🔜 Dealer claim-specific utilities
- 🔜 Dealer claim-specific types
## Benefits
1. **True Modularity**: Delete folder = Remove all functionality
2. **No Orphaned Code**: All related code is in one place
3. **Easy Maintenance**: Find everything for a flow in its folder
4. **Independent Development**: Work on flows without affecting others
5. **Clear Boundaries**: Know exactly what belongs to which flow
6. **Simple Removal**: Remove a flow type in 2 steps
## File Organization Rules
### ✅ Flow-Specific → Flow Folder
- RequestDetail screen → `flows/{flow}/pages/RequestDetail.tsx`
- Request detail components → `flows/{flow}/components/request-detail/`
- Request creation → `flows/{flow}/components/request-creation/`
- Flow-specific hooks → `flows/{flow}/hooks/`
- Flow-specific services → `flows/{flow}/services/`
- Flow-specific utils → `flows/{flow}/utils/`
- Flow-specific types → `flows/{flow}/types/`
### ✅ Shared → Shared Folder
- Components used by ALL flows → `flows/shared/components/`
### ✅ Routing → Main RequestDetail
- Flow detection and routing → `pages/RequestDetail/RequestDetail.tsx`
## Example: Adding a New Flow Type
1. **Create folder structure**:
```
flows/vendor-payment/
├── components/
│ ├── request-detail/
│ └── request-creation/
├── pages/
│ └── RequestDetail.tsx # Complete screen
└── index.ts
```
2. **Update registry** (`flows/index.ts`):
```typescript
import * as VendorPaymentFlow from './vendor-payment';
export const FlowRegistry = {
CUSTOM: CustomFlow,
DEALER_CLAIM: DealerClaimFlow,
VENDOR_PAYMENT: VendorPaymentFlow,
};
```
3. **That's it!** The flow is now plug-and-play.
## Example: Removing a Flow Type
1. **Delete folder**: `rm -rf flows/dealer-claim/`
2. **Update registry**: Remove from `FlowRegistry` and `getRequestDetailScreen()`
3. **Done!** All dealer claim code is removed.
## Current Status
**Completed**:
- Custom flow folder with RequestDetail screen
- Dealer claim flow folder with RequestDetail screen
- Main RequestDetail router
- Flow registry with routing
- Shared components folder
🔜 **Future Enhancements**:
- Move flow-specific hooks to flow folders
- Move flow-specific services to flow folders
- Move flow-specific utilities to flow folders
- Move flow-specific types to flow folders
## Conclusion
The architecture is now **truly modular and self-contained**. Each flow folder is a complete, independent module. Deleting a folder removes all related code with zero dependencies remaining. This makes the codebase maintainable, scalable, and easy to understand.
