Summary

Transforms foyer into a configurable, tested, reproducible static SPA ready for nixpkgs (pkgs/by-name/fo/foyer/package.nix):

• Runtime /config.json Catalogue (src/lib/config.ts, static/config.json): Replaces hardcoded fleet inventory (services.ts and hosts.ts removed) with validated runtime /config.json loading, URL scheme sanitization (http:/https: and single-slash root-relative paths), weather coordinate bounds checks, and duplicate-ID filtering.
• Data & Domain Layer (src/lib/portal.ts, src/lib/data/gatus.ts): Removes hardcoded status.kleinbem.dev and probe alias chain; adds buildGatusStatusesUrl, AbortSignal.any, visibility-aware polling, crypto.randomUUID() bookmark creation, NaN-guarded Open-Meteo parsing, and unified multi-token ⌘K search (#host, @category, !network, >) across services, pinned bookmarks, and hosts.
• Frontend & @kleinbem/web-config#13 (src/lib/components/, src/routes/+page.svelte): Consolidates host filtering into HostBar.svelte (removes duplicate HostFilter.svelte and local StatusDot.svelte), upgrades modals to native <dialog closedby="any"> (showModal()) with combobox/listbox/aria-activedescendant ARIA and scrollIntoView({ block: 'nearest' }), replaces $effect state mutations with Svelte 5 writable $derived, aligns header clock updates to minute boundaries, and adopts @kleinbem/web-config 91a902ed6aec552ba103aa90b5597b1d2081148d (defineWebConfig deterministic build version + @theme inline tokens).
• Automated Tests (test/): Adds 34 tests across 16 suites using Node's built-in node:test + svelte/compiler SSR hooks (test/setup.ts) with zero extra npm dependencies, and enforces svelte-check --fail-on-warnings.
• Nix Packaging & Hygiene (nix/package.nix, flake.nix, LICENSE): Replaces importNpmLock IFD with buildNpmPackage (finalAttrs: ...) + npmDepsHash, sets strictDeps = true and __structuredAttrs = true, runs tests + svelte-check in checkPhase, verifies static output and /nix/store leak absence in installCheckPhase, adds an offline AF_UNIX Caddy passthru.tests.smoke check, drops flake-utils, and adds the MIT LICENSE.

Verification

• nix flake check -L (sandboxed foyer build, 34/34 unit & SSR tests, svelte-check --fail-on-warnings, installCheckPhase, and Caddy smoke check)
• nix build --rebuild --no-link .#default (bit-for-bit reproducible)
• nixfmt --check, deadnix --fail, statix check, actionlint, zizmor, yamllint, markdownlint-cli2, gitleaks, osv-scanner
• Follow-up before bumping foyer in nix-presets: mount/serve fleet /config.json in nix-presets/containers/dashboard/foyer/default.nix.

Walkthrough

The pull request changes Foyer from a fixed fleet portal to a configuration-driven static SPA. It adds configuration parsing and portal helpers, updates page and component behaviour, and adds Nix packaging, automated tests, CI checks, and documentation.

Changes: Foyer runtime portal

Layer / File(s)	Summary
Configuration contracts and portal helpers src/lib/types.ts, src/lib/config.ts, src/lib/portal.ts, src/lib/index.ts, static/config.json, test/config-and-portal.test.ts	Adds portal configuration types, defaults, parsing and loading, plus bookmark, palette, service, and weather helpers. The shipped configuration provides Foyer branding, empty host and service lists, and a source link. Tests cover parsing, validation, and helper results.
Configuration-driven page and service rendering src/routes/+page.svelte, src/routes/+layout.svelte, src/lib/data/gatus.ts, src/lib/components/{Header,HostBar,CategorySection,LayoutToggle,ServiceCard}.svelte, src/lib/components/{HostFilter,StatusDot}.svelte, src/app.{css,html}, test/components.test.ts, test/gatus.test.ts	The page derives host counts, service metrics, filters, and categories from loaded configuration. Gatus polling uses the configured URL. Host and service components render supplied data; shared theme classes and app-shell theme handling are updated. Component and Gatus tests cover the changed output and lookup behaviour.
Palette, bookmarks, and weather interactions src/lib/components/{CommandPalette,BookmarksSection,WeatherWidget,Header}.svelte, src/routes/+page.svelte, test/components.test.ts	The palette supports services, bookmarks, and hosts, with configured web search and keyboard navigation. Bookmarks use shared parsing and creation helpers, storage events, and a native dialog. Weather refreshes use configured settings and the shared fetch helper.
Build, tests, and project documentation .github/workflows/ci.yml, flake.nix, nix/package.nix, vite.config.ts, package.json, justfile, test/{setup.ts,env.d.ts,app-shell.test.ts}, README.md, AGENTS.md, LICENSE, tsconfig.json	Adds the Nix package, package and smoke checks, and test-runner support. CI and project instructions use the updated checks. Documentation describes runtime configuration and deployment, and the MIT licence is added.

Change: Feature

Merge Risk: Low · previous review bfa1a

This change makes Foyer configurable at runtime. The remaining issues are small edge cases: tests may not start on Node 22.17, a failed config load shows an empty portal without explanation, and a few unusual inputs behave incorrectly. They are worth fixing but do not block use.

Full details: Title check

Explanation

The title names three changes: a runtime /config.json catalogue, an SSR test suite, and a nixpkgs-ready build. The changeset covers all three: config.ts and the static config.json replace hard-coded inventories, test/ adds 34 tests with Svelte SSR hooks, and flake.nix and nix/package.nix add packaging and checks. The title is long and lists several changes, but it is related to the main change.

only still-valid issues, skip the rest with a brief reason, keep changes
minimal, and validate.

Inline comments:
Review comments at @nix/package.nix:
- Around line 32-33: Update the comment above makeCacheWritable to include a
link to the relevant upstream issue or PR; if this is an integration requirement
rather than an upstream bug, document the reason using the required no-link
annotation.

Review comments at @package.json:
- Line 16: Update the package.json test script to enable Node.js type stripping
before importing test/setup.ts, so npm test works on Node.js 22.17.x. Preserve
the existing test discovery and setup import, and keep the command compatible
with the declared engines.node range.

Review comments at @src/lib/components/CommandPalette.svelte:
- Around line 43-46: Update the CommandPalette scroll-reset behaviour so changes
to query or filtered.length scroll the result list to the top, keeping the list
aligned with the selection reset to index 0. Use the existing list element
reference and preserve the current selection behaviour.

Review comments at @src/lib/components/HostBar.svelte:
- Line 70: Separate the all-hosts selection from configured host IDs in the
HostBar selection and filtering flow: ensure a configured host with id 'all' can
be selected and filtered independently. Either reserve and validate that ID
during configuration parsing or use a distinct all-hosts value consistently
across the filter controls and filterServices, preserving the existing all-hosts
behaviour.

Review comments at @src/lib/components/WeatherWidget.svelte:
- Line 16: Add a visibilitychange listener in the WeatherWidget component that
triggers the existing weather refresh when the document becomes visible, so a
skipped initial request is retried on return to the tab. Remove the listener
during component cleanup, preserving the existing in-flight guard and refresh
behaviour.

Review comments at @src/lib/config.ts:
- Around line 215-217: Update the configuration-loading warning logic so fetch
rejection and five-second timeout produce a load-failure warning instead of
silently returning empty defaults, while caller-initiated cancellation remains
silent. Preserve the existing SyntaxError warning and default-configuration
behaviour.

Review comments at @src/lib/data/gatus.ts:
- Line 21: Update the URL construction around `trimmed` and
`ENDPOINTS_STATUS_PATH` to check and append the status path on the URL pathname,
not after the query string. Preserve the query separately and support both
same-origin paths and absolute URLs, including URLs that already end with the
status path.

Review comments at @src/lib/portal.ts:
- Line 202: Change the host-count aggregation around hostCounts so the overall
service total is stored separately from the per-host counts. Ensure a host ID of
total is counted only as that host, while the aggregate total filter still
reports services.length; preserve the existing host-count behaviour for other
IDs.
- Line 72: Update the URL normalization in the bookmark flow so bare
hostname-and-port inputs such as grafana.example.test:3000 receive the HTTPS
prefix before scheme validation. Preserve explicit HTTP and HTTPS URLs, and
continue rejecting non-HTTP schemes through isValidHttpUrl.

Review comments at @src/routes/+page.svelte:
- Line 223: The footer each block can receive multiple links with the same URL,
so its key is not guaranteed to be unique. Update the loop in the footer
rendering to be unkeyed or use an identity unique to each configured link,
preserving distinct links even when their URLs match.
