Mara hit:
TypeError: can't access property "innerHTML", root is null
renderContainers app.js:666
applyContainerStateChanged app.js:484
container_state_changed app.js:2306
…on /flow.html. The same bundled `app.js` runs on both /index.html
(dashboard, has the tab panes) and /flow.html (flow page, has only
the broker terminal). SSE events arrive on every page —
`container_state_changed` / `tombstones_changed` / `approval_*` /
`question_*` route through their corresponding renderers, which
then `root.innerHTML = ''` on `$('section-id')` and crash when the
section isn't in the DOM.
The convention is already "no-op when the target DOM doesn't
exist" — `renderMetaInputs`, `renderRebuildQueue`, `renderReminders`
all guard with `if (!root) return;` at the top. Bring the rest in
line:
- `renderContainers`
- `renderTombstones`
- `renderQuestions`
- `renderApprovals`
`renderInbox` already handles the absent case via its
`if (root && !root.hidden)` branch — no change.
No behaviour change on /index.html. On /flow.html the failing
events silently no-op as intended (terminal renderers still
re-render the broker tail normally).

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).
