Ports the shadow-DOM <hive-jobq-graph> custom element
(frontend/packages/shared/src/jobq-graph/) to a Preact component
(JobqGraph.js) shared by the dashboard and swarm-ui, per hyperhive#3310.
- JobqGraph.js: written with plain h() calls (no JSX) so the same file
compiles unmodified under both the dashboard's text-loader CSS config
and swarm-ui's JSX config. Exports `JobqGraph` for JSX use and
`mountJobqGraph(container, props)` for the dashboard's non-JSX
imperative mount, returning a `{refresh(), update()}` handle matching
the old custom element's public surface. Same rendering contract as
before: indented state tree, payload.label verbatim, payload.data as
a generic key/value list, "waits on: <label>" text for Node-kind deps,
per-state filter checkboxes, optional cancel button.
- jobq-graph.css: light-DOM adaptation of the old shadow-scoped
stylesheet (:host -> .jg-root, otherwise unchanged).
- dashboard/src/builds.js: local mountJobqGraph() renamed to
mountRebuildQueue() to avoid colliding with the newly-imported shared
mountJobqGraph; cancel handling is now a plain onCancel callback
instead of a DOM CustomEvent listener (no shadow boundary to cross
anymore).
- dashboard + shared package.json: added preact as a dependency (matches
swarm-ui's existing pin, 10.29.8) - the dashboard was a vanilla-JS MPA
with no Preact/JSX pipeline before this.
- Removed the old hive-jobq-graph.js/.css entirely (confirmed via grep
it had exactly one consumer, dashboard/src/builds.js, so this is a
clean swap, not parallel maintenance of two implementations).
- Updated stale doc-comment references to the old element name in
builds.html, tabs.js, swarm.js, docs/web-ui/dashboard.md, and
hive-c0re/src/job_queue/mod.rs.
Verified: npm run build (whole frontend workspace) and npm run
typecheck (swarm-ui) both clean; cargo build/clippy/test -p hive-c0re
all clean (331 tests, 0 failures); headless-chromium screenshot of
/builds.html against a mock GET /api/jobq/graph payload confirms full
visual/behavioral parity with the old custom element (tree, filter
checkboxes, cancel buttons, error text, waits-on line, data list, live
build log panel).
This covers the dashboard-replacement half of hyperhive#3310 only. The
swarm-ui half (rendering the CreateAgent DAG on the agent-creation page)
is downstream of hyperhive#3306/#3124 landing - no swarm-ui page exists
yet to mount it in.
Project-bootstrap scope per the issue: static build as a nix pkg,
empty start page for now, functionality deferred until auth against
authelia is figured out. Stack (Preact + wouter + TypeScript + JSX)
matches the shell decision from the earlier framework-paths thread —
a real SPA shell with a router and deep links, distinct from the
per-hive dashboard's vanilla-JS + custom-element MPA.
- New npm workspace frontend/packages/swarm-ui: one route (/), a
wouter Switch/Route shell, a 404 fallback. Reuses @hive/shared's
colors.css/theme.css/base.css for visual consistency; no other
shared JS (the vanilla-JS el()/dom.js helpers are superseded by
Preact in this shell).
- nix/packages/swarm-ui.nix: its own buildNpmPackage derivation
(scoped to just this workspace via an explicit buildPhase), not
folded into nix/packages/frontend.nix's packages.default closure —
same reasoning swarm-controller/swarmctl already use for staying out
of daemonBins: a hive that doesn't run the swarm controller
shouldn't carry swarm-ui bytes.
- npmDepsHash recomputed in both frontend.nix and swarm-ui.nix (same
shared lockfile, new deps: preact, wouter-preact, typescript).
- Added swarm-ui to nix/checks.nix alongside frontend, for the same
FOD-staleness reason plus being the only thing that actually builds
it in CI (not in packages.default's closure like frontend is, so
nix flake check wouldn't otherwise touch it).
- npm run typecheck (tsc --noEmit) is available locally; not yet wired
into CI — esbuild transpiles TS without type-checking, so that's a
real gap, left as a follow-up rather than growing this bootstrap PR
with a new CI workflow step.
Verified: nix build .#swarm-ui and .#frontend both succeed; npm run
build (root, all workspaces) succeeds; tsc --noEmit clean;
scripts/check-issue-refs.sh clean.
Both mdNode implementations (agent UI app.js, dashboard common.js)
assigned marked.parse() output straight to innerHTML with no
sanitizer. marked v5+ dropped its built-in sanitize option, and there
was no DOMPurify anywhere in frontend/, so markdown containing raw
HTML/script tags rendered live in the browser.
Both sinks receive untrusted input in practice: the agent UI's mdNode
renders recv tool_result bodies, assistant prose, and send/ask/answer
payloads sourced from peer agents and matrix-relayed messages (the
documented prompt-injection adversary); the dashboard's mdNode renders
agent-authored .md files served verbatim by GET /api/state-file
(the endpoint validates path, not content). Since the per-agent UI and
dashboard are same-origin behind the gateway with operator-authority
endpoints (approve/spawn/rebuild/destroy/answer-question), injected
script would run with the operator's session.
Fix: DOMPurify.sanitize() the marked.parse() output at both sinks
before assigning to innerHTML. Added dompurify as a dependency to
both the agent and dashboard npm workspaces, recomputed npmDepsHash
in nix/frontend.nix for the updated lockfile. Also corrected
docs/web-ui/shape.md, which claimed the markdown-rendering path was
XSS-safe by construction the same way the text-node-based linkify
path is — it isn't; it's safe because it's sanitized.
CSP hardening for the dashboard (no unsafe-inline) is a separate,
larger backend change (response headers in hive-c0re) and is left as
a fast-follow rather than folded into this fix.
Follow-up to 9e558c3. Runs `npm install` with the new nodejs_22 + npm
toolchain that just landed in iris's container (approval dfae406),
which generates the lockfile + node_modules tree. Only the lockfile
is checked in; node_modules/ stays in .gitignore.
Pinned versions (resolved by npm from the package.json constraints):
- chart.js 4.4.4 (replaces the jsDelivr CDN script on stats.html)
- marked 4.3.0 (replaces hive-fr0nt/assets/marked.umd.js)
- esbuild 0.25.5 (bumped from 0.24.0 to clear an audit warning
about the dev-server CSRF advisory; bundling
behaviour is unaffected)
Validated locally:
npm install — 0 vulnerabilities reported
npm run build — both workspace builds succeed
dashboard: dist/{app.js (149kb), dashboard.css (33kb), index.html}
agent: dist/{app.js (114kb), stats.js (435kb), agent.css (16kb),
index.html, stats.html, screen.html}
Stripped-comment diff of dist/dashboard.css vs the runtime concat
(BASE_CSS + TERMINAL_CSS + assets/dashboard.css) shows only
whitespace + comment-strip differences — selectors/properties match.
Hermetic-build wiring (the Nix `buildNpmPackage` derivation that
consumes this lockfile) lands in Phase 2 on a follow-up commit.
