Summary

  • Clears every npm audit advisory in ui and docs/docs (28 and 10 findings, including critical Vite/Vitest and Next.js issues).
  • Updates Next.js to 16.4.0, React Router to 7.18.4, Vite to 6.4.4, Vitest to 5.0.4, and Tailwind CSS to 4.3.3.
  • Keeps the existing class-based theme on Tailwind 4, and maps shadow-sm, backdrop-blur-sm, and outline-none to their v4 equivalents.
  • Includes the standalone Traefik datasource fix from smoochy (Fix/config proxy active traefik source #108). When active_data_source is traefik, GET /api/v1/traefik-config is built from Middleware Manager state and does not call Pangolin. Pangolin mode still fetches, and a Pangolin failure with an empty cache returns an error.

Validation

  • npm audit reports 0 vulnerabilities in both package trees.
  • vite build succeeds for the UI, and next build succeeds for the docs site.
  • Dashboard, dark mode, and middleware search were checked in the browser on the dev server and the built UI.
  • CGO_ENABLED=1 go test -race -count=1 -timeout 12m ./... passed.
  • npm run build in ui passed (tsc -b && vite build). npx vitest run found no UI test files on this branch and exited 1.

Summary by CodeRabbit

  • New Features
    • Traefik configuration is available when Traefik is the active data source, even if Pangolin cannot be reached.
  • Bug Fixes
    • Proxy status and configuration retrieval now work in standalone Traefik mode.
    • Host-based routing now handles ambiguous matches consistently, avoiding unintended changes to router priorities or middleware.
  • Documentation
    • Updated setup and data-source guidance to describe standalone Traefik configuration access.

…s/paths

findMatchingRouter() matched routers only on Host(...) and returned the
first router found while iterating an unordered Go map. When a host is
served by more than one non-redirect router - e.g. Pangolin's multi-target
path routing, where one resource with several Targets produces multiple
routers sharing an identical Host() but differing PathPrefix() - the
function returned whichever router Go's randomized map iteration visited
first. Since the router map is freshly deserialized on every 5s cache
refresh, the winner changed from call to call, and the caller
(applyResourceOverrides) mutates the returned router's `priority` field in
place - so a resource's RouterPriority override could land on the wrong
sibling router, corrupting its priority and creating a priority tie between
routers whose relative order must stay fixed.

Fix: sort matches deterministically, and when more than one non-redirect
router shares a host, treat it as ambiguous (host alone cannot identify the
correct router) and report no match instead of guessing. The caller already
skips the override entirely when no router is found, so this leaves
Pangolin's own router configuration - including its own priority - untouched
in the ambiguous case, which is strictly safer than corrupting it.

Fixes #113
…rect-only fallback (review feedback)

CodeRabbit review on PR #114 flagged two findings:

- The case-1 branch of findMatchingRouter checked router entryPoints for
  "websecure" but returned the same router either way, making the check
  dead code. Removed it; behavior is unchanged.
- The case-0 branch (host matches only -redirect routers, deterministic
  fallback to the first match) had no test coverage. Added a subtest that
  asserts the fallback stays deterministic across repeated calls.
Bump Next.js, Vite, Vitest, React Router, and Tailwind to patched releases, and keep the existing class-based theme on Tailwind 4.

📝 Walkthrough

The config proxy now builds configuration based on the active data source and handles ambiguous host matches deterministically. The changes also update proxy documentation and tests, migrate UI styling to Tailwind CSS 4, and update frontend dependencies.

Changes: Proxy Configuration

Layer / File(s) Summary
Data-source configuration
services/config_proxy.go, services/config_proxy_datasource_test.go, services/config_proxy_test.go, services/resource_watcher_test.go
GetMergedConfig builds standalone configuration when Traefik API is active and fetches Pangolin configuration otherwise. Tests cover both data-source paths, and watcher tests read running state with Load().
Router matching and TLS domains
services/config_proxy.go, services/config_proxy_test.go
Host matches are sorted by router name. Ambiguous matches with multiple non-redirect routers return no match. TLS conversion preserves non-string domain values. Tests cover matching and ambiguous override behavior.
Proxy endpoint checks and documentation
api/handlers/proxy_test.go, docs/docs/content/docs/configuration/data-sources.mdx, docs/docs/content/docs/getting-started/deploy-standalone.mdx
Handler tests check status and configuration responses with Traefik active. Documentation states that the config proxy can operate without Pangolin in this mode.

UI Styling Migration

Layer / File(s) Summary
Tailwind and frontend tooling setup
ui/package.json, ui/postcss.config.js, ui/src/styles/globals.css, ui/tailwind.config.ts
The UI adopts Tailwind CSS 4 imports and PostCSS configuration. Dependency versions change for Tailwind, PostCSS, Vite, Vitest, and react-router-dom.
UI utility class updates
ui/src/components/plugins/PluginHub.tsx, ui/src/components/ui/*
Components replace outline utilities and update selected shadow and backdrop-blur utilities.

Documentation Site Dependency

Layer / File(s) Summary
Next.js version update
docs/docs/package.json
The documentation package updates Next.js from 16.0.10 to 16.4.0.

Merge Risk: 🔵 Low · up to 5d292

A misconfigured standalone deployment can unexpectedly contact Pangolin, and the UI can lose its intended container spacing. Correct those behaviors and the test counter before merging, or explicitly accept the bounded risk.

A rabbit checked the proxy path,
Then watched the config take its shape.
The routers lined up by name,
While Tailwind changed its frame.
Fresh styles crossed the UI floor,
And documentation noted more.

Fix non-deterministic router priority for hosts with multiple Targets/paths
These two checks existed only on the issue/107 reimplementation: Pangolin mode still contacts Pangolin, and a Pangolin failure with an empty cache returns an error.

Make the hits counter concurrency-safe.

httptest runs the handler on a server goroutine. The HTTP response completion does not create a Go happens-before edge for the plain hits++ write and the later plain read. This test can therefore race under go test -race.

Make the hits counter in the HTTP handler test concurrency-safe: replace the
plain integer increment and read with atomic operations, updating the assertion
to compare the loaded value with the expected count.

Do not fall back to Pangolin when the active data source lookup fails.

GetActiveDataSourceConfig returns an error when the active name has no matching entry or has an unknown type. buildBaseConfig then retains models.PangolinAPI and calls cp.fetchPangolinConfig(). This violates the documented Traefik-mode contract that Pangolin must not be consulted. Logging the error unconditionally does not fix the incorrect fetch. Propagate the lookup error instead.

Suggested fix
 		if dsConfig, err := cp.configManager.GetActiveDataSourceConfig(); err == nil {
 			activeType = dsConfig.Type
-		} else if shouldLogInfo() {
-			log.Printf("Warning: failed to read active data source for config proxy, defaulting to Pangolin: %v", err)
+		} else {
+			return nil, fmt.Errorf("failed to read active data source for config proxy: %w", err)
 		}

Update buildBaseConfig to return an error when GetActiveDataSourceConfig fails
instead of retaining the PangolinAPI default and proceeding to fetch Pangolin
config. Preserve the existing source selection when the lookup succeeds.

Preserve the configured container behavior in CSS.

Tailwind CSS 4 does not apply the legacy theme.container.center and theme.container.padding options. The UI uses container in App.tsx, Header.tsx, and Footer.tsx. Add the equivalent CSS utility with the configured 2rem padding.
