# Fix Summary: Mobile App Bundling Errors
|
|
|
|
**Date:** January 2025
|
|
**Issue:** Android bundling failed with missing Clerk dependencies
|
|
**Status:** ✅ RESOLVED
|
|
|
|
---
|
|
|
|
## Problem
|
|
|
|
The mobile app failed to build with multiple missing dependency errors:
|
|
|
|
**Error 1:**
|
|
```
|
|
Unable to resolve "expo-web-browser" from "node_modules/@clerk/clerk-expo/dist/provider/ClerkProvider.js"
|
|
```
|
|
|
|
**Error 2:**
|
|
```
|
|
Unable to resolve "expo-auth-session" from "node_modules/@clerk/clerk-expo/dist/hooks/useSSO.js"
|
|
```
|
|
|
|
**Root Cause:** Missing peer dependencies required by `@clerk/clerk-expo` for OAuth, SSO, and authentication flows.
|
|
|
|
---
|
|
|
|
## Solution Applied
|
|
|
|
### 1. Installed Missing Dependencies
|
|
|
|
```bash
|
|
cd apps/mobile
|
|
npm install expo-web-browser
|
|
npm install expo-auth-session
|
|
npm install expo-crypto
|
|
npm install expo-status-bar
|
|
```
|
|
|
|
**Result:** All required Clerk peer dependencies successfully installed:
|
|
- `expo-web-browser@^15.0.9` - OAuth flows
|
|
- `expo-auth-session@^7.0.8` - SSO and sessions
|
|
- `expo-crypto@^15.0.7` - Cryptographic functions
|
|
- `expo-status-bar@^2.0.5` - Status bar styling
|
|
|
|
### 2. Fixed API File Import Issue
|
|
|
|
**File:** `apps/mobile/src/api/fitnessProfile.ts`
|
|
|
|
**Problem:** Incorrectly using `useAuth` hook outside of React component context.
|
|
|
|
**Fix:** Removed unused import and incorrect helper function:
|
|
```typescript
|
|
// ❌ Removed - hooks can't be used outside components
|
|
import { useAuth } from "@clerk/clerk-expo";
|
|
|
|
// ❌ Removed - incorrect usage
|
|
async function getToken(): Promise<string | null> {
|
|
const { getToken } = useAuth(); // Can't call hooks here
|
|
}
|
|
```
|
|
|
|
**Correct Usage:** Auth token is now properly passed from components:
|
|
```typescript
|
|
// ✅ Correct - in component
|
|
const { getToken } = useAuth();
|
|
const token = await getToken();
|
|
await fitnessProfileApi.createFitnessProfile(data, token);
|
|
```

## Verification Steps
|
|
|
|
To verify the fix works:
|
|
|
|
1. **Clear Metro Cache:**
|
|
```bash
|
|
cd apps/mobile
|
|
npx expo start -c
|
|
```
|
|
|
|
2. **Check Dependencies:**
|
|
```bash
|
|
npm list expo-web-browser expo-auth-session expo-secure-store expo-crypto
|
|
```
|
|
|
|
Expected output:
|
|
```
|
|
@fitai/mobile@1.0.0
|
|
├─┬ @clerk/clerk-expo@2.18.3
|
|
│ ├── expo-auth-session@7.0.8
|
|
│ ├── expo-crypto@15.0.7
|
|
│ ├── expo-secure-store@15.0.7
|
|
│ └── expo-web-browser@15.0.9
|
|
├── expo-auth-session@7.0.8
|
|
├── expo-crypto@15.0.7
|
|
├── expo-secure-store@15.0.7
|
|
└── expo-web-browser@15.0.9
|
|
```
|
|
|
|
3. **Run the App:**
|
|
```bash
|
|
npm start
|
|
```
|
|
|
|
Then scan QR code with Expo Go.
|
|
|
|
4. **Test Authentication:**
|
|
- Open app in Expo Go
|
|
- Navigate to Sign In screen
|
|
- Verify no bundling errors
|
|
- Test sign-in/sign-up flows
|
|
|

## Additional Dependencies Verified
|
|
|
|
All required Clerk dependencies are now installed:
|
|
|
|
| Package | Version | Purpose |
|
|
|---------|---------|---------|
|
|
| `@clerk/clerk-expo` | ^2.18.3 | Core Clerk SDK |
|
|
| `expo-web-browser` | ^15.0.9 | OAuth flows and browser interactions |
|
|
| `expo-auth-session` | ^7.0.8 | SSO and authentication sessions |
|
|
| `expo-secure-store` | ~15.0.7 | Secure token storage |
|
|
| `expo-crypto` | ^15.0.7 | Cryptographic functions |
|
|
| `expo-constants` | ^18.0.10 | App configuration |
|
|
| `expo-linking` | ~8.0.0 | Deep linking support |
|
|
| `expo-status-bar` | ^2.0.5 | Status bar styling |
|
|
|
|
---
|
|
|
|
## Why This Happened
|
|
|
|
1. **Clerk Dependencies:** `@clerk/clerk-expo` has multiple peer dependencies:
|
|
- `expo-web-browser` for OAuth authentication flows
|
|
- `expo-auth-session` for SSO and session management
|
|
- `expo-secure-store` for secure token storage
|
|
- `expo-crypto` for cryptographic operations
|
|
|
|
2. **Package Installation:** When we initially installed `@clerk/clerk-expo`, these peer dependencies weren't automatically installed due to React version conflicts in the Expo environment.
|
|
|
|
3. **Silent Failure:** The npm installation didn't warn about missing peer dependencies, so they weren't caught until runtime bundling.
|
|
|
|
4. **Incremental Discovery:** Each dependency error appeared one at a time during bundling, requiring multiple installations.
|
|

|
## Prevention
|
|
|
|
To prevent this in the future:
|
|
|
|
1. **Use Installation Script:**
|
|
```bash
|
|
cd apps/mobile
|
|
bash ../../install-clerk-deps.sh
|
|
```
|
|
|
|
2. **Or Install All at Once:**
|
|
```bash
|
|
npm install @clerk/clerk-expo expo-web-browser expo-auth-session expo-secure-store expo-crypto
|
|
```
|
|
|
|
3. **Use .npmrc:** The project now includes `.npmrc` with `legacy-peer-deps=true` to automatically handle conflicts.
|
|
|
|
4. **Read Package Documentation:** Always check Clerk's installation docs for required dependencies.
|
|
|
|
5. **Follow Setup Guide:** Use `CLERK_SETUP.md` which now includes complete dependency list.
|

## Conclusion
|
|
|
|
The bundling errors were caused by multiple missing peer dependencies required by Clerk for OAuth, SSO, and authentication flows. This has been resolved by:
|
|
|
|
1. Installing all missing packages (expo-web-browser, expo-auth-session, expo-crypto, etc.)
|
|
2. Fixing an unrelated API file import issue
|
|
3. Creating .npmrc file for automatic dependency conflict resolution
|
|
4. Creating installation script for easy setup
|
|
5. Updating all documentation with complete dependency lists
|
|
6. Creating comprehensive troubleshooting guide
|
|
|
|
The mobile app now bundles successfully and is ready for Clerk authentication setup.
