# Extension Implementation Status

## Current State: ✅ COMPLETE - Ready for Production Testing

### What's Complete ✅

1. **Environment Configuration**
   - Dev/prod builds with correct API URLs
   - Build: `npm run build` (dev) or `npm run build:prod`
   - Dev: `http://127.0.0.1:8888`
   - Prod: `https://atlast.byarielm.fyi`

2. **Server Health Check**
   - Extension checks if dev server is running (dev mode only)
   - Shows "Server offline" state with instructions
   - "Check Again" button to retry

3. **Authentication Flow**
   - Extension checks `/session` endpoint on init
   - Shows "Not logged in" state if no session
   - "Open ATlast" button to log in
   - "Check Again" to retry after login
   - **User must be logged in to ATlast BEFORE using extension**

4. **Upload Flow** (matches file upload)
   - Scan Twitter Following page
   - POST to `/extension-import` (requires auth)
   - Backend:
     - Gets DID from session
     - Creates `user_upload` entry
     - Saves to `source_accounts` table
     - Returns `uploadId`
   - Opens `/results?uploadId={id}`
   - Frontend searches and displays (same as file upload)

5. **CORS Permissions**
   - Extension has host_permissions for:
     - `http://127.0.0.1:8888/*`
     - `http://localhost:8888/*`
     - `https://atlast.byarielm.fyi/*`

6. **Cleanup Complete**
   - ❌ Removed `extension_imports` table
   - ❌ Removed `get-extension-import` function
   - ❌ Removed `ExtensionImport.tsx` page
   - ❌ Removed `/import/:id` route
   - ❌ Removed `utils/import-store.ts`

### What Needs Testing 🧪

1. **Full Flow Test**
   ```bash
   # 1. Start dev server
   npx netlify-cli dev --filter @atlast/web

   # 2. Build extension
   cd packages/extension
   npm run build

   # 3. Load extension in Chrome
   chrome://extensions/ → Load unpacked → packages/extension/dist/chrome/

   # 4. Log in to ATlast
   Open http://127.0.0.1:8888 → Log in

   # 5. Go to Twitter
   https://twitter.com/justadev_atlast/following

   # 6. Open extension popup
   - Should show "Ready to scan Twitter/X"
   - Click "Start Scan"
   - Wait for completion
   - Click "Open in ATlast"
   - Should open /results?uploadId={id}
   - Results should load and search automatically
   ```

2. **Error Cases to Test**
   - Not logged in → should show login prompt
   - Server offline → should show offline state
   - Empty results → should show appropriate message
   - Network errors → should handle gracefully

### Recently Completed (Dec 2024 - Jan 2025) 🎉

**Extension Flow Fixes:**
- ✅ NaN database error - Fixed missing `matchedUsers` parameter in `extension-import.ts` (node #287)
- ✅ Database initialized successfully (node #288)
- ✅ API response unwrapping - Fixed api-client to access ApiResponse.data field (nodes #290-295)
- ✅ Loading screen during extension upload search (node #325)
- ✅ Timezone fixes - All timestamp columns use TIMESTAMPTZ (node #326)
- ✅ Vite dev server optimization - Pre-bundling dependencies for faster startup (node #327)

**Decision Graph Documentation:**

- ✅ Improved decision graph workflow with lifecycle management (node #332)
- ✅ Updated CLAUDE.md with node status transitions and common mistakes

### Current Status 📊

**All extension bugs resolved!** The extension is fully functional and ready for production testing and deployment.

### Next Steps 📋

1. ✅ Build extension: `cd packages/extension && pnpm run build`
2. ✅ Reload extension in Chrome
3. ✅ Test login flow
4. ✅ Test scan and upload
5. ✅ Verify results page works
6. ✅ All bugs fixed
7. 🔜 Test production build: `pnpm run build:prod`
8. 🔜 Chrome Web Store submission
9. 🔜 Firefox Add-ons support and submission

### Architecture Notes 📝

**Removed temporary import storage approach:**
- Previously tried in-memory storage (doesn't work in serverless)
- Then tried database storage with temp table (overkill)

**Current approach:**
- User logs in to ATlast FIRST
- Extension requires authentication
- Upload creates permanent records immediately
- No temporary storage needed
- Matches file upload behavior exactly

**Why this is better:**
- Simpler architecture
- No temporary storage to expire
- Proper user association from the start
- Reuses existing upload/search infrastructure
- Same flow as file uploads (consistency)

### Files Modified in Latest Refactor

**Deleted:**
- `packages/functions/src/get-extension-import.ts`
- `packages/functions/src/utils/import-store.ts`
- `packages/web/src/pages/ExtensionImport.tsx`

**Modified:**

- `packages/functions/src/infrastructure/database/DatabaseService.ts` - Removed extension_imports table
- `packages/functions/src/core/types/database.types.ts` - Removed ExtensionImportRow
- `packages/web/src/Router.tsx` - Removed /import/:id route
- `packages/extension/src/popup/popup.ts` - Added session check, login state
- `packages/extension/src/popup/popup.html` - Added not-logged-in state
- `packages/extension/src/lib/api-client.ts` - Added checkSession(), credentials: 'include'
