- web/src/components/AssistantChat/messages/UserMessage.tsx now subscribes only to role, text, status,
and localId instead of the entire message object to avoid re-renders caused by unrelated message state
changes (hover/isLast/etc.).
- web/src/components/AssistantChat/messages/SystemMessage.tsx now subscribes only to role, text, and icon
for the same reason.
- This reduces unnecessary renders observed in React DevTools without changing message UI or behavior.
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.
Wrap SessionHeader content in a centered container using the same
mx-auto w-full max-w-[720px] pattern as HappyThread to ensure the
back button and session info align with the main content area instead
of appearing at the top-left corner.
Slim down SessionSummary responses to reduce payload size:
- Replace full todos array with computed todoProgress summary
- Replace metadata object with only necessary fields (name, path, summary.text)
- Remove unused fields (thinking, createdAt, permissionMode, modelMode)
- Refactor sorting to work on full Session objects before mapping
This significantly reduces /api/sessions response size, especially for
sessions with many todos or tools.
Use the cached message converter from @assistant-ui/react to prevent
re-converting all messages on every render. The previous implementation
called convertMessage for every ChatBlock on each render cycle, creating
new objects (Date, arrays, metadata) that triggered unnecessary state
updates and re-render storms.
The new implementation:
- Uses useExternalMessageConverter which internally caches via WeakMap
- Memoizes callbacks with useCallback for stable references
- Memoizes the adapter object to prevent subscription churn
Implement block reconciliation to maintain object identity across renders when content hasn't changed, reducing unnecessary re-renders. Add memoization and performance optimizations to ToolCard component.
Enable concurrent web development workflow with Vite HMR instead of requiring pre-build. Configure Vite server to listen on 0.0.0.0 for LAN access, proxy /api and /socket.io to backend (127.0.0.1:3006), and run dev:server and dev:web together.
The conditional Telegram SDK loading (commit 4606ba2) caused dark mode to
break in non-Telegram browsers. Added dark mode CSS variable overrides with
proper fallbacks, and restored the module-level applyTheme() call that applies
theme before React renders, preventing a flash of incorrect styling.
- web/src/index.css: Added dark mode overrides for primary colors (--app-bg,
--app-fg, --app-hint, --app-link, --app-button, --app-button-text,
--app-secondary-bg) with system-appropriate dark fallbacks when Telegram
theme variables are unavailable
- web/src/hooks/useTheme.ts: Restored module-level applyTheme(currentScheme)
call to ensure theme is applied before React renders
Add comprehensive support for the AskUserQuestion tool including:
- New footer component for handling user responses with multi-step question flow
- Type definitions and parsing utilities for question and answer formats
- View component for displaying questions and options
- Integration with permission system to capture user answers
- Support for single and multi-select questions with optional text input
- Haptic feedback and error handling for better UX
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.
Improve service worker update handling to fix caching issues during development:
- Add skipWaiting and clientsClaim in Workbox config for immediate SW activation
- Remove user confirmation prompt and switch to silent automatic updates
- Replace hourly polling with visibility-based update checks via visibilitychange event
This resolves the issue where web updates would not take effect without manual cache clearing.
Remove unreliable conditions from Telegram environment detection in useAuthSource:
- window.Telegram !== undefined: Always true due to unconditional SDK loading
- window.self !== window.top: Causes false positives in iframe scenarios
Only keep URL parameter detection (tgWebApp in search/hash) which is reliable.
This prevents 5-second polling delay before login page displays on PC browser.
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.
Replaces react-shiki with a custom minimal Shiki highlighter to significantly reduce bundle size. Only loads 29 common languages and 2 themes (github-light/dark), using the JavaScript RegExp engine instead of WASM.
- Reduced web bundle from 5.8MB to 2.5MB (57% reduction)
- Saves 622KB by avoiding WASM runtime
- Graceful fallback for unsupported languages
- Removed react-shiki dependency
- Added @shikijs/langs, @shikijs/themes, shiki, hast-util-to-jsx-runtime
- Added light mode CSS rules for syntax highlighting
- 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 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
Replace no-op browser haptic feedback with Web Vibration API support,
allowing haptic feedback when running outside Telegram Mini App. Also
remove stale react-syntax-highlighter type reference from tsconfig.
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
Consolidate markdown rendering logic into dedicated assistant-ui components and update syntax highlighting to use Shiki with GitHub themes. Removes dependency on react-markdown and react-syntax-highlighter in favor of @assistant-ui/react-markdown with Shiki-based highlighting.
Consolidate markdown rendering logic into dedicated assistant-ui components and update syntax highlighting to use Shiki with GitHub themes. Removes dependency on react-markdown and react-syntax-highlighter in favor of @assistant-ui/react-markdown with Shiki-based highlighting.
