Additional Pages Implementation - 2025-11-16

Summary

Built out Login and Settings pages (Tasks T105-T109, T120), added React Router for navigation, and implemented protected routes.

What Was Built

1. Auth Service (T105-T107)

File: frontend/src/services/auth.ts

Functions:

• login() - Redirect to /auth/login for HF OAuth
• getCurrentUser() - GET /api/me to fetch user profile
• getToken() - POST /api/tokens to generate new API token
• logout() - Clear token and redirect
• isAuthenticated() - Check if user has token
• getStoredToken() - Get current token from localStorage

2. Login Page (T108)

File: frontend/src/pages/Login.tsx

Features:

• ✅ Centered card layout with app branding
• ✅ "Sign in with Hugging Face" button (primary)
• ✅ "Continue as Local Dev" button (for development)
• ✅ Clean, professional dark mode design
• ✅ Responsive layout

Local dev mode sets a dummy token in localStorage for testing without backend OAuth.

3. Settings Page (T109, T120)

File: frontend/src/pages/Settings.tsx

Features:

• ✅ Profile Card

  • User avatar (from HF profile or fallback initials)
  • Username and user ID display
  • Vault path
  • Sign Out button

• ✅ API Token Card

  • Bearer token display (password field)
  • Copy to clipboard button (with success feedback)
  • "Generate New Token" button
  • MCP configuration example with actual token

• ✅ Index Health Card

  • Note count display
  • Last updated timestamp
  • Last full rebuild timestamp
  • "Rebuild Index" button with loading state
  • Success message after rebuild

4. Routing & Protected Routes

File: frontend/src/App.tsx

Added React Router v6:

• /login - Public login page
• / - Protected main app (requires auth)
• /settings - Protected settings page (requires auth)
• Auto-redirect to /login if not authenticated

5. Navigation Integration

Updated MainApp.tsx:

• Added Settings button (gear icon) in header
• Clicking navigates to /settings
• Back button in Settings returns to /

Pages Flow

└─────────────────────────────────────┘

Dark Mode

All pages use dark mode by default (set in main.tsx).

Dependencies Added

npm install react-router-dom

Backend Integration Status

Pages are fully built but show loading states or errors because backend APIs don't exist yet:

• Login page: Works (local dev mode bypasses OAuth)
• Settings page:
  • Profile: Shows "Loading user data..." (needs GET /api/me)
  • API Token: Shows token from localStorage (needs POST /api/tokens)
  • Index Health: Shows "Loading index health..." (needs GET /api/index/health)
  • Rebuild Index: Button present (needs POST /api/index/rebuild)

What Works Right Now

✅ Login page displays ✅ Local dev login works (sets token, redirects to main app) ✅ Protected routes redirect to login if no token ✅ Settings page displays with proper layout ✅ Token copy to clipboard works ✅ Navigation between pages works ✅ Back button works ✅ Sign out clears token and returns to login

What Needs Backend

⏳ HF OAuth flow (backend routes /auth/login, /auth/callback) ⏳ User profile data (GET /api/me) ⏳ Token generation (POST /api/tokens) ⏳ Index health data (GET /api/index/health) ⏳ Index rebuild (POST /api/index/rebuild)

Task Status

✅ T105 - Auth service login function ✅ T106 - Auth service getCurrentUser function ✅ T107 - Auth service getToken function ✅ T108 - Login page with HF OAuth button ✅ T109 - Settings page with profile and token ✅ T120 - Rebuild index button in settings

Testing

Login Page

1. Navigate to http://localhost:5173/
2. Should redirect to /login (no token)
3. Click "Continue as Local Dev"
4. Should redirect to main app

Settings Page

1. From main app, click Settings icon (⚙️)
2. Should show Settings page with 3 cards
3. Profile shows "Loading..." (expected - no backend)
4. Token shows "local-dev-token"
5. Click Copy button → token copied to clipboard
6. Index Health shows "Loading..." (expected - no backend)

Navigation

1. Click Back button → returns to main app
2. Click Settings icon → returns to settings
3. Sign out from settings → returns to login page

All navigation works perfectly!

Summary

3 new pages built and integrated:

• ✅ Login page with HF OAuth + local dev mode
• ✅ Settings page with profile, tokens, and index health
• ✅ Routing with protected routes

Ready for backend integration - Once you implement the backend auth routes (T095-T104), the pages will be fully functional!
