Implement push notification system with VAPID keys, client service worker integration, and push subscription management. Includes server-side PushService for sending notifications and PushNotifier for reactive event handling, plus client-side usePushNotifications hook and service worker support.
Adds support for hosting the web UI separately from the hapi server on static hosts (GitHub Pages, Cloudflare Pages). Users can now set a custom server origin via a dialog on the login screen, with the ability to return to same-origin behavior.
Changes include:
- New useServerUrl hook for managing server URL configuration and storage
- Updated API client to support baseUrl parameter for all requests
- Enhanced login UI with server picker dialog (top-right button)
- Auth system now keys tokens per baseUrl to support multiple servers
- SSE connection updated to use configured baseUrl
- Documentation updates for standalone hosting setup
Add additional condition to check for the intermediate auth state where
authSource exists but token hasn't been fetched yet. This prevents the
LoginPrompt from briefly flashing when the page is refreshed and the user
already has a stored access token.
Changes the condition from just `isAuthLoading` to also cover the gap
before the useAuth effect starts fetching the token, displaying the
loading state instead of the login prompt.
Introduces two reusable loading components to standardize loading states:
- Spinner: Base spinner with accessibility support (role, aria-label)
- LoadingState: Semantic loading indicator combining spinner and label
Updates loading patterns across the app:
- Full-screen/block loading now uses LoadingState (App, router, files, file)
- Inline button loading states show spinner + text with aria-busy
- Message list loading replaced with MessageSkeleton component
- Removes duplicate SpinnerIcon definition from PermissionFooter
Improves UX and accessibility:
- Loading screens centered and full-height
- Consistent ellipsis character (…)
- Semantic accessibility (role="status", aria-live, aria-busy)
- Adds CSS variables for banner styling
Added isFirstConnectRef to distinguish between first SSE connection
(page load) and subsequent reconnects (session switches). Only the
first connection forces the banner to show; subsequent connects use
non-forced mode which only displays the banner when returning from
background within 30s, eliminating unwanted banner flashes on
session changes.
Implement two key UX improvements:
1. Syncing banner with visibility tracking:
- New useSyncingState hook manages syncing state with safety timeout
- Banner shows when SSE connects/reconnects
- Auto-hides after 10s to prevent stuck spinner
- Smart visibility detection to suppress banner when returning from background
2. Smart scroll behavior for chat thread:
- Only auto-scrolls when user is near bottom (<120px threshold)
- Shows "X new messages" indicator when user is reading history
- Smooth scroll to bottom with indicator button
- Resets state on session change
Files:
- New: useSyncingState hook for syncing state management
- New: SyncingBanner component for non-blocking indicator
- Modified: App.tsx integrates syncing with SSE handling
- Modified: HappyThread implements smart scroll with dynamic autoScroll
- Modified: index.css adds spinner and bounce-in animations
Replace state-based screen navigation with proper URL-based routing. This includes:
- New router configuration with routes for sessions, machines, and spawn pages
- App context provider to share API and token across the app
- useAppGoBack hook for handling browser and Telegram back navigation
- Refactored App component to render outlet and use router hooks
- Memory history for Telegram app, browser history for web
Replace manual state management with TanStack Query (React Query) for more robust server state handling. This refactoring introduces:
- New hooks for queries: useSessions, useSession, useMessages, useMachines
- New hooks for mutations: useSendMessage, useSessionActions, useSpawnSession
- Centralized query client with optimized configuration (5s staleTime, disabled window focus refetch)
- Query key factory for consistent cache invalidation
- Improved message synchronization via socket events with cache updates
- Optimistic updates for message sending with retry capability
- Simplified App.tsx by removing manual state management logic
- Integrated React Query devtools in development mode
This enables automatic cache management, better error handling, and a foundation for more sophisticated data fetching patterns.
Add lazy loading of Telegram SDK only when running inside Telegram Mini App
environment instead of unconditionally loading in all browsers. Includes:
- New environment detection functions: isTelegramEnvironment(), isTelegramApp()
- Dynamic SDK loading with 3s timeout via loadTelegramSdk()
- Removed static script tag from index.html
- Made haptic feedback lazy (SDK check on each call)
- Made theme listeners lazy (attached in initializeTheme())
- Updated all components to use unified detection functions
This prevents SDK load time overhead in regular browser environments while
ensuring the app works correctly both in Telegram and browser contexts.
Syncs React routing state with browser History API. Clicking the browser
back button now navigates within the app instead of exiting. Telegram
BackButton behavior is preserved by checking for initData.
- Add iOS Safari install prompt with step-by-step modal guide
- Fix Telegram environment detection (check initData, not just SDK presence)
- Fix install prompt re-entrancy issue (clear deferredPrompt immediately)
- Extract icon components to separate file (web/src/components/icons.tsx)
- Rename "Happy App" to "Hapi" throughout the UI and manifests
- Change button/icon colors from blue (--app-button) to neutral theme (--app-fg/--app-bg)
- Add install dismiss state to prevent repeated prompts
- Improve iOS Safari detection with robust user agent parsing
Add complete PWA implementation including service worker registration,
offline support, and installation prompts:
- Add vite-plugin-pwa and workbox-window dependencies for PWA tooling
- Configure VitePWA plugin with web app manifest and app metadata
- Set up Workbox caching strategies for API endpoints and CDN assets
- Implement service worker auto-update with user-triggered refresh
- Create usePWAInstall hook to handle beforeinstallprompt events
- Create useOnlineStatus hook for monitoring network connectivity
- Add InstallPrompt component with haptic feedback integration
- Add OfflineBanner component to notify users of offline status
- Configure PWA icons and assets (64x64, 192x192, 512x512 variants)
- Add TypeScript type declarations for virtual PWA register module
- Integrate PWA components and service worker into App.tsx and main.tsx
- Add PWA meta tags and viewport configuration to index.html
Enable the web client to run in plain browser environments alongside Telegram Mini App support:
- Server: Add CLI_API_TOKEN authentication path as alternative to Telegram initData
- Client: Add useAuthSource hook to detect and manage Telegram vs browser auth sources
- Client: Add usePlatform hook for platform abstraction with graceful haptic feedback degradation
- Client: Add LoginPrompt component for browser access token login
- Client: Extend useTheme to fall back to system prefers-color-scheme in browser
- Client: Migrate all direct HapticFeedback calls to use usePlatform hook
