* fix(hub): raise maxRequestBodySize so file uploads work The Bun server inherited maxRequestBodySize from Socket.IO's default maxHttpBufferSize (1 MB). The upload endpoint sends files as base64 in JSON, so any image > ~750 KB was silently rejected before reaching the route handler. The frontend allows 50 MB uploads. Raise the limit to at least 100 MB to accommodate 50 MB files with base64 encoding overhead (~33%). via [HAPI](https://hapi.run) Co-Authored-By: HAPI <noreply@hapi.run> * fix(hub,web): fix file uploads — raise body limit, lower max size, show errors Three changes: 1. hub/server.ts: Bun's maxRequestBodySize inherited Socket.IO's 1 MB default, silently rejecting any upload. Raise to 10 MB. 2. hub/routes + web/attachmentAdapter: lower MAX_UPLOAD_BYTES from 50 MB to 5 MB (realistic for images; 5 MB base64 ≈ 6.7 MB body, fits within the 10 MB server limit). 3. web/AttachmentItem: show "Upload failed" text and strike-through filename on error, instead of just a tiny icon. via [HAPI](https://hapi.run) Co-Authored-By: HAPI <noreply@hapi.run> * fix(hub): keep 50MB upload limit, size maxRequestBodySize to match Bot review correctly flagged that lowering MAX_UPLOAD_BYTES to 5 MB regresses the documented 50 MB limit. Revert to 50 MB and calculate maxRequestBodySize properly: 50 MB × 4/3 (base64) + 1 MB (JSON overhead) ≈ 68 MB. via [HAPI](https://hapi.run) Co-Authored-By: HAPI <noreply@hapi.run> --------- Co-authored-by: HAPI <noreply@hapi.run>
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.
- Permission mode and model selection.
- Machine list and remote session spawn.
- File browser and git status/diff views.
- PWA install prompt and offline banner.
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>(orCLI_API_TOKENfor 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.
Routes
See src/router.tsx for route definitions.

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.

Development
From the repo root:
bun install
bun run dev:web
If testing in Telegram, set:
HAPI_PUBLIC_URLto the public HTTPS URL of the dev server.CORS_ORIGINSto include the dev server origin.
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:
- Build the web app. If your static host uses a subpath, set the Vite base:
bun run build:web -- --base /<repo>/
- Deploy
web/distto your static host. - Set hub CORS to allow the static origin (
HAPI_PUBLIC_URLorCORS_ORIGINS). - 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.
