Ports the row taxonomy in docs/terminal-rendering.md (app.js's renderStream/renderRichToolUse/renderToolResult/renderTaskEvent) to real Preact components + hooks: - lib/streamRow.ts: plain-data StreamRow model (one row = one line/ panel), lib/classifyEvent.ts: raw stream-json event -> StreamRow[], almost entirely dispatching on the backend's precomputed _icon/ _summary/_category/_body/_body_type fields, same as the old client. - lib/markdown.ts, lib/linkify.tsx: sanitized-markdown + auto-link helpers, same behavior as app.js's mdNode/terminal.js's linkify. - hooks/useLiveStream.ts: backfill + SSE + seq-dedupe + coalescing, reduced to a plain StreamRow[] — deliberately has no opinion on scroll position, only on what rows exist. - components/Row.tsx: renders one StreamRow (flat or details). - components/LiveStream.tsx: owns the scrollable DOM node + a from- scratch sticky-bottom implementation — not the old MutationObserver + rAF snap-animation + smoothScrollingUntil gate. stickToBottom is plain state driven by the scroll handler; snapping is an instant scrollTop write in a useLayoutEffect that runs after Preact has already committed the new rows, so it always sees the real scrollHeight. A load-older prepend is told apart from a normal append via an explicit ref set right before calling loadMore(), rather than inferred from DOM mutation shape after the fact. Wired into Root.tsx below Header/StatusChips; turn_start/turn_end also nudge useAgentState's refresh() for a snappier badge update than the plain poll interval. Reuses @hive/shared/terminal.css's existing row-kind classes as-is — the taxonomy's visual language isn't what changed, the component model underneath it is. |

hyperhive frontend
npm workspaces project for the hyperhive browser-facing assets:
packages/shared/— shared modules used by both surfaces (terminal pane, Catppuccin palette + body typography).packages/dashboard/— the hive-c0re dashboard SPA.packages/agent/— the per-container web UI (default agent page, stats, screen).
Build
npm install # one-off; uses the checked-in package-lock.json
npm run build # builds every workspace into packages/*/dist/
The Rust binaries serve packages/dashboard/dist/ and
packages/agent/dist/ via tower_http::ServeDir at runtime; the
build derivation is wired up in nix/modules/frontend.nix. Per-agent
additions are layered on top of the default agent dist via the
hyperhive.frontend.extraFiles option in agent.nix.
Why npm + esbuild
- Hermetic: dependencies vendored via the checked-in lockfile;
buildNpmPackagein nix uses it as the source-of-truth so the output is reproducible without network access at build time. - esbuild: vanilla-JS bundler, no framework runtime overhead.
Each workspace's
build.mjsis ~30 lines. - Single-PR migration: see issue #273 for the design proposal and the four-commit shape (npm scaffold → nix derivations → container plumbing → Rust cutover).
