Server (index.ts):
- migrate to Hono streamSSE, mounted under Bun.serve fetch handler
- idleTimeout: 255 fixes the silent Bun 10s timeout that killed SSE
responses before the first keepalive could fire (root cause of the
empty EventStream tab)
- stream.onAbort wires an AbortController into upstream fetch signal
- 15s : keepalive raw SSE comments for Cloudflare 120s headroom
- decodeDataUrl returns Uint8Array<ArrayBuffer> for DOM Blob types
- chromeDevToolsAutomaticWorkspaceFolders: false silences the
'Unable to add filesystem' warning in sandboxed browsers
Client (client.ts new):
- extracted from inline <script> — Bun only bundles external script src,
not inline module imports, so node_modules bare specifiers must live
in their own file
- @microsoft/fetch-event-source replaces hand-rolled fetch +
ReadableStream parsing; supports POST + body + signal natively
- client aborts the loop on event:done so fetchEventSource doesn't retry
Build:
- drop unused react/react-dom/@types/react* deps (KISS)
- add 'DOM', 'DOM.Iterable' to tsconfig lib for client.ts
