Wires the new /api/pty WebSocket into the dashboard as a top-level
Chat tab. Clicking Chat (or the ▶ play icon on any session row)
spawns a PTY running hermes --tui and renders its ANSI output with
xterm.js in the browser.
Frontend
--------
web/src/pages/ChatPage.tsx
* @xterm/xterm v6 + @xterm/addon-webgl renderer (pixel-perfect cell
grid — DOM and canvas renderers each have layout artifacts that
break box-drawing glyph connectivity in a browser)
* @xterm/addon-fit for container-driven resize
* @xterm/addon-unicode11 for modern wide-char widths (matches Ink's
string-width computation so kaomoji / CJK / emoji land on the
same cell boundaries as the host expects)
* @xterm/addon-web-links for URL auto-linking
* Rounded dark-teal "terminal window" container with 12px internal
padding + drop shadow for visual identity within the dashboard
* Clipboard wiring:
- Ctrl/Cmd+Shift+C copies xterm selection to system clipboard
- Ctrl/Cmd+Shift+V pastes system clipboard into the PTY
- OSC 52 handler writes terminal-emitted clipboard sequences
(how Ink's own Ctrl+C and /copy command deliver copy events);
decodes via TextDecoder so multi-byte UTF-8 codepoints
(U+2265, emoji, CJK) round-trip correctly
- Plain Ctrl+C still passes through as SIGINT to interrupt a
running response
* Floating "copy last response" button in the bottom-right corner.
Triggers Ink's /copy slash by sending bytes in two frames with a
100ms gap — Ink's tokenizer coalesces rapid adjacent bytes into
a paste event (bypasses the slash dispatcher), so we deliberately
split '/copy' and '\r' into separate packets to land them as
individual keypresses.
web/src/App.tsx
Chat nav entry (Terminal icon) at position 2 and <Route path="/chat">.
web/src/pages/SessionsPage.tsx
Play-icon button per session row that navigates to /chat?resume=<id>;
the PTY bridge forwards the resume param to hermes --tui --resume.
web/src/i18n/{en,zh,types}.ts
nav.chat label + sessions.resumeInChat action label.
web/vite.config.ts
/api proxy gains ws: true so WebSocket upgrades forward to :9119
when running Vite dev mode against a separate hermes dashboard
backend.
web/src/index.css + web/public/fonts-terminal/
Bundles JetBrains Mono (Regular/Bold/Italic, Apache-2.0, ~280 KB
total) as a local webfont. Fonts live outside web/public/fonts/
because the sync-assets prebuild step wipes that directory from
@nous-research/ui every build.
Package deps
------------
Net new: @xterm/xterm ^6.0.0, @xterm/addon-fit ^0.11.0,
@xterm/addon-webgl ^0.19.0, @xterm/addon-unicode11 ^0.9.0,
@xterm/addon-web-links ^0.12.0.
Bundle impact: +420 KB minified / +105 KB gzipped. Acceptable for a
feature that replaces what would otherwise be a rewrite of the entire
TUI surface in React.
Backend contract preserved
---------------------------
Every TUI affordance (slash popover, model picker, tool cards,
markdown streaming, clarify/sudo/approval prompts, skin engine, wide
chars, mouse tracking) lands in the browser unchanged because we are
running the real Ink binary. Adding a feature to the TUI surfaces in
the dashboard immediately. Do NOT add parallel React chat surfaces.
