# Bug Fixes - Local Development Setup

## Summary
Fixed critical issues blocking local development after Cloudflare migration.

## Issues Fixed

### 1. OAuth API Breaking Changes (✅ Fixed)
**Problem:** `@atcute/oauth-node-client` v1.1.0 removed `importJwkKey` export

**Solution:**
- Updated to use `ClientAssertionPrivateJwk` type directly
- Parse JWK JSON and pass as array to keyset parameter
- Updated key generation script to use `generateClientAssertionKey`

**Files Changed:**
- `src/lib/server/auth.ts`
- `scripts/generate-key.ts`

### 2. Missing Local Development Fallbacks (✅ Fixed)
**Problem:** App required Cloudflare D1 and KV which aren't available in local dev

**Solution:**
- Database: Falls back to better-sqlite3 when D1 not available
- OAuth Storage: Falls back to MemoryStore when KV not available
- Environment: Reads from process.env when platform.env not available
- Added dotenv back for local development

**Files Changed:**
- `src/lib/server/db.ts`
- `src/lib/server/auth.ts`
- `src/hooks.server.ts`

### 3. ESM/CommonJS Module Issues (✅ Fixed)
**Problem:** `require is not defined` error in ESM modules

**Solution:**
- Use `createRequire` from 'module' to enable CommonJS in ESM
- Keep getDb synchronous to avoid breaking 16+ call sites

**Files Changed:**
- `src/lib/server/db.ts`

### 4. OAuth Key Generation (✅ Fixed)
**Problem:** Key generation script using old API, detecting commented keys

**Solution:**
- Updated to use `generateClientAssertionKey` from @atcute/oauth-crypto
- Fixed regex to only detect uncommented PRIVATE_KEY_JWK lines

**Files Changed:**
- `scripts/generate-key.ts`

## Current Status

### ✅ Working
- OAuth key generation (`npm run setup:key`)
- Database initialization (SQLite local fallback)
- Environment configuration (.env loading)
- Build process (`npm run build`)

### ⚠️ Needs Testing
- Dev server runtime (`npm run dev`)
- OAuth login flow
- Game creation and moves
- Image generation endpoints

### 📋 Next Steps
1. Test dev server with all endpoints
2. Verify OAuth flow works end-to-end
3. Test game creation and gameplay
4. Add reactions feature
5. Deploy to Cloudflare Pages

## Development Setup

To run locally:
```bash
# 1. Install dependencies
npm install

# 2. Generate OAuth keys
npm run setup:key

# 3. Start dev server
npm run dev
```

The app will use:
- SQLite database at `./data/app.db`
- MemoryStore for sessions/state
- OAuth with generated JWK keys

## Deployment Notes

For Cloudflare Pages deployment:
- D1 database will be used instead of SQLite
- KV namespaces will be used instead of MemoryStore
- Environment secrets from Cloudflare dashboard
