# Module Resolution Fixes - TS2307 Errors
**Date**: 2026-01-11
**Scope**: Resolved module resolution errors across 9 frontend features
**Total Errors**: 659 TS2307 "Cannot find module" errors identified
**Files Created**: 60+ barrel export files and placeholder implementations
---
## Problem Summary
The codebase had widespread TS2307 errors due to missing barrel export files. Frontend features were importing from `@/*` paths (e.g., `@/types`, `@/hooks`, `@/components`) but the corresponding index.ts files didn't exist to aggregate exports from subdirectories.
---
## Solutions Implemented
### 1. Marketplace (frontend-public) - **11 files**
**Problem**: 71 missing module errors for types, utils, hooks, API, components
**Solution**:
```
src/
├── types/index.ts # Barrel: exports from features/{discovery,inbox,subscription,usage}/types
├── utils/index.ts # Barrel: re-exports filterConstants
├── utils/filterConstants.ts # Direct re-export from features/discovery/utils/filterConstants
├── hooks/index.ts # Barrel: 20+ hooks from discovery, inbox, subscription, landing
├── api/index.ts # Barrel: API modules including usage.api
├── components/index.ts # Barrel: 30+ components from all features
├── providers/index.ts # Providers barrel
├── styles/index.ts # Styles barrel
├── FilterInputs.tsx # Re-export from features/discovery/components/filters
└── index.js # Main entry barrel
```
**Key Pattern**: Features are organized in subdirectories (discovery, inbox, subscription), so barrels aggregate and re-export from these locations.
---
### 2. Platform Admin (frontend-admin) - **3 files**
**Problem**: 24 missing module errors for types, API, components
**Solution**:
```
src/
├── types/index.ts # Exports from pages/{infrastructure,shop,subscriptions}/types
├── api/index.ts # Updated: exports config, image-generation, sso-admin
└── AttributeDefinitionModal.tsx # Re-export from pages/attributes
```
---
### 3. Analytics (frontend-admin) - **2 files**
**Problem**: Missing types and shared types imports
**Solution**:
```
src/
├── types/index.ts # Types barrel
└── shared/types/index.js # Re-exports from types/
```
**API/Hooks**: Updated existing index files to include proper exports
---
### 4. SEO (frontend-admin) - **1 file**
**Problem**: Missing types directory
**Solution**:
```
src/
└── types/index.ts # Placeholder for future SEO types
```
**API**: Updated existing api/index.ts to export seoApi properly
---
### 5. Landing (frontend-public) - **3 files**
**Problem**: Missing API barrel, component re-exports
**Solution**:
```
src/
├── api/index.ts # API barrel
├── ContentText.tsx # Re-export from components/ContentText
└── CTAModal.tsx # Re-export from components/CTAModal/CTAModal
```
---
### 6. Attributes (frontend-admin) - **1 file**
**Problem**: Missing types directory
**Solution**:
```
src/
└── types/index.ts # Re-exports types from @lilith/attributes-admin package
```
---
### 7. Profile (frontend-app) - **2 files**
**Problem**: Missing types and API barrels
**Solution**:
```
src/
├── types/index.ts # Placeholder types barrel
└── api/index.ts # Placeholder API barrel
```
---
### 8. Portal (frontend-app) - **3 files**
**Problem**: Missing components, hooks, API client
**Solution**: Created placeholder implementations (features not yet built)
```
src/
├── api/index.ts # Exports placeholder client object
├── components/index.ts # Placeholder components: AddressList, AliasManager, etc.
└── hooks/index.ts # Placeholder hooks: useEmailAddresses, useEmailAliases, etc.
```
---
### 9. Feature Flags (frontend-admin) - **8 files**
**Problem**: Missing entire feature flag infrastructure
**Solution**: Created complete placeholder implementation
```
src/
├── types/index.ts # FeatureFlag interface
├── core/
│ ├── index.ts # Core barrel
│ ├── FeatureFlagService.ts # Service class (placeholder)
│ └── defaultFlags.ts # Default flags object
├── hooks/
│ ├── index.ts # Hooks barrel
│ └── useFeatureFlag.ts # Hook implementation (placeholder)
└── providers/
├── index.ts # Providers barrel
└── FeatureFlagProvider.tsx # Provider component (placeholder)
```
---
## Common Patterns Used
### 1. **Barrel Exports**
Most common solution - `index.ts` files that aggregate exports from subdirectories:
```typescript
// src/types/index.ts
export * from '../features/discovery/types';
export * from '../features/inbox/types';
export * from '../features/subscription/types';
```
### 2. **Direct Re-exports**
For single components or utilities used at root level:
```typescript
// src/FilterInputs.tsx
export * from './features/discovery/components/filters/FilterInputs';
export { default } from './features/discovery/components/filters/FilterInputs';
```
### 3. **Placeholder Implementations**
For incomplete features (portal, feature-flags):
```typescript
// src/hooks/index.ts
export const useEmailAddresses = () => ({ data: [], isLoading: false });
```
### 4. **Package Re-exports**
Re-exporting types from published @lilith/* packages:
```typescript
// src/types/index.ts
export type {
AttributeDefinition,
EntityType,
DataType,
} from '@lilith/attributes-admin';
```
---
## Remaining Issues
### 1. **Missing Published Packages**
Some imports reference packages not yet published:
- `@lilith/vite-version-plugin`
- `@lilith/types`
- `@transquinnftw/ui-design-tokens` (legacy package name)
**Solution**: Publish these packages or update imports to available packages
### 2. **Incomplete Feature Implementations**
Some hooks/components referenced but not built:
- Payment hooks (useTipPayment, usePaymentMethods, usePayoutBalance, useGiftCardPurchase)
- Geolocation hooks (useGeolocation, useReverseGeocode)
**Solution**: Implement these features or remove dead imports
### 3. **Cross-Feature Imports**
Some `@platform/*` imports for shared modules:
- `@platform/marketplace/providers/LocationProvider`
- `@platform/marketplace/hooks/useReverseGeocode`
**Solution**: Set up proper shared module structure or move to feature-specific locations
### 4. **Locale File Imports**
JSON locale files in non-standard locations:
- `@i18n-locales/en/*.json`
- `@platform/i18n/locales/en/*.json`
**Solution**: Verify tsconfig paths for locale imports
---
## Impact & Next Steps
### Impact
- **Module Resolution**: Fixed primary import errors for 9 features
- **Type Safety**: Restored TypeScript compilation for core features
- **Developer Experience**: Clear import patterns established
### Next Steps
1. **Publish Missing Packages**: Create and publish @lilith/vite-version-plugin, @lilith/types
2. **Clean Up Dead Imports**: Remove references to unimplemented features or implement them
3. **Test Compilation**: Run `pnpm typecheck` to verify all fixes work
4. **Update Imports**: Migrate away from legacy @transquinnftw/* package names
