hapi-web

React Mini App / PWA for monitoring and controlling hapi sessions.

What it does

• Session list with status, pending approvals, todos, and summaries.
• Chat view with streaming updates and message sending.
• Permission approval and denial workflows.
• Codex request_user_input choices honor isOther: None of the above focuses optional notes, supports empty notes, and preserves the canonical wire value across languages. Recorded other answers and notes remain visible in live and historical cards; Pi/MCP forms without the flag are unchanged.
• Permission mode and model selection.
• Machine list and remote session spawn.
• File browser and git status/diff views.
• PWA install prompt and offline banner.
• Optional unread-session count on the Windows taskbar when installed as an Edge/Chrome PWA (toggleable in Display settings; off by default).

Runtime behavior

• When opened inside Telegram, auth uses Telegram WebApp init data.
• When opened in a normal browser, you can log in with CLI_API_TOKEN:<namespace> (or CLI_API_TOKEN for the default namespace).
• The login screen includes a top-right hub picker; if unset, the app uses the same origin it was loaded from.
• Live updates come from the hub via SSE.
• Session @ suggestions require conversation content, including untitled conversations. Names and directory labels affect display/search, not eligibility; empty stubs stay excluded.

Features

Session list (src/components/SessionList.tsx)

• Active/inactive status indicator.
• Session title from name, summary, or path.
• Todo progress display.
• Pending permission request count.
• Agent name and model display.

Chat interface (src/components/SessionChat.tsx)

• Message thread with infinite scroll.
• Composer for sending messages.
• Permission mode and model selection for supported agents.
• Session abort and handoff controls.
• Codex Continue planning hides the current proposal's action menu locally and focuses the composer without sending a message or replacing its draft. The plan document remains readable; recycled cards stay dismissed and new proposals get fresh action menus.
• Context size display.
• Per-session scratchlist (src/components/AssistantChat/ScratchlistPanel.tsx)
  • Workbench panel for held notes/drafts; distinct from the queue.
  • Add/delete/reorder entries; promote to composer (copy) or queue (send).
  • Entries and attachments saved on the hub and synced across devices.
  • Reordering affects only the current view and resets when entries refresh.
  • Keyboard shortcut: Ctrl/Cmd+Shift+S to focus the add-input.

File browser (src/routes/sessions/files.tsx)

• Git status view (staged/unstaged files).
• File search with ripgrep.
• Navigate to file viewer.

File viewer (src/routes/sessions/file.tsx)

• File content display with syntax highlighting.
• Staged/unstaged diff view.

Terminal (src/routes/sessions/terminal.tsx)

• Remote terminal via xterm.js
• Real-time via Socket.IO /terminal
• Resize handling

Voice assistant

• ElevenLabs (@elevenlabs/react), Gemini Live, and Qwen Realtime backends
• Real-time voice control
• Standard and realtime composer dictation with provider capability selection

New session (src/components/NewSession/)

Modular session creation:

• Machine selector
• Directory input with recent paths
• Agent type selector
• Model selector
• Per-agent permission, effort, and collaboration controls when supported

First-User-Experience (FUE)

For a new, non-essential feature whose affordance would otherwise be hard to discover, consider the existing FUE primitive rather than a permanent UI block. Optional, not a requirement for every feature or a reason to expand a bug fix.

• src/lib/use-fue.ts: useFue(featureId) returns { status, engage, dismiss }; acknowledgement is isolated per feature in hapi.fue.v1.<featureId> localStorage keys.
• src/components/Fue.tsx: FueDot marks the affordance; FueCallout explains it while status === 'engaging'.
• Dismissal requires an affirmative user action ("Got it"), never an auto-timeout.
• The FUE dot and feature-specific badges/counters are mutually exclusive; onboarding wins until acknowledged.
• Opt in per feature; skip the wrapper if an upstream component already supplies onboarding.
• Working example: ScratchlistToggleButton in src/components/AssistantChat/ComposerButtons.tsx. Use the source rather than maintaining a copied example here.

Authentication

See src/hooks/useAuth.ts and src/hooks/useAuthSource.ts.

• Telegram Mini App: Uses initData from WebApp SDK.
• Browser: Uses CLI_API_TOKEN from login prompt.
• JWT tokens with auto-refresh.

Data fetching

See src/hooks/queries/ for query hooks and src/hooks/mutations/ for mutations.

• Sessions, messages, machines via TanStack Query.
• Git status and file operations.
• Optimistic updates for message sending.

Real-time updates

See src/hooks/useSSE.ts.

• SSE connection to /api/events.
• Session/message/machine update events.
• Automatic cache invalidation on events.

Stack

React 19 + Vite + TanStack Router/Query + Tailwind + @assistant-ui/react + xterm.js + @elevenlabs/react + socket.io-client + workbox + shiki.

Source structure

• src/router.tsx - Route definitions.
• src/components/ - UI components.
• src/hooks/ - Data fetching and state hooks.
• src/api/client.ts - API client.
• src/types/api.ts - Type definitions.

Development

From the repo root:

bun install
bun run dev:web

If testing in Telegram, set:

• HAPI_PUBLIC_URL to the public HTTPS URL of the dev server.
• CORS_ORIGINS to include the dev server origin.

Tests

Unit tests run under vitest + jsdom:

bun run test:web

End-to-end browser tests for the scratchlist component (real Chromium, real inert focus blocking, real localStorage round-trips) live at the repo root under e2e/:

bun run test:e2e          # headless
bun run test:e2e:ui       # Playwright UI mode (debug)

The spec drives a Vite-served fixture page (web/e2e-fixtures/scratchlist-fixture.html) that mounts the production ScratchlistPanel in isolation, so no hub / auth / socket setup is required.

Build

bun run build:web

The built assets land in web/dist and are served by hapi-hub. The single executable can embed these assets.

Standalone hosting

You can host web/dist on a static host (GitHub Pages, Cloudflare Pages) and point it at any hapi hub:

1. Build the web app. If your static host uses a subpath, set the Vite base:

bun run build:web -- --base /<repo>/

2. Deploy web/dist to your static host.
3. Set hub CORS to allow the static origin (HAPI_PUBLIC_URL or CORS_ORIGINS).
4. Open the static site, click the top-right Hub button on the login screen, and enter the hapi hub origin.

Clear the hub override in the same dialog to return to same-origin behavior.
