After a deploy a browser could keep the old entry document, which named a bundle that no longer exists, and the missing script was answered with the entry document, so the page was blank with only a MIME-type error to say why. The hashed bundle is immutable and a missing file is a 404; the entry document, the worker, the manifest, the icons and the theme's colors.css are revalidated. The pages carry a content security policy. The service worker fetches its shell past the HTTP cache, logs a failed install, refreshes the cached entry document on each navigation and holds cache writes open with waitUntil. The proxy test pins the cache rules, the 404s and the policy; docs/swarm/ui.md says what the browser keeps. |

hyperhive frontend
npm workspaces project for the hyperhive browser-facing assets:
packages/shared/— shared modules used by every surface (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).packages/swarm-ui/— the swarm-level operator UI shell (hives, agents, jobs, issue-report pages).
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;
nix/packages/frontend.nix wires up the build derivation. The
services.hyperhive.agent.frontend.extraFiles option in agent.nix
layers per-agent additions on top of the default agent dist.
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:
agentandswarm-uiare Preact apps;dashboardis a vanilla-JS + custom-element MPA with a few Preact-rendered pages (builds.js,agents.js, imported by the dashboard entry);sharedholds both kinds of module. No framework runtime beyond Preact where it's used. Each workspace'sbuild.mjsis a short esbuild script. - Single-PR migration: see the tracked design proposal and the four-commit shape (npm scaffold → nix derivations → container plumbing → Rust cutover).
