First of the six planned live integrations (Proxmox, Synology, Semaphore,
Tailscale, Gitea, Dockhand), reusing Sloth Manager's existing Tailscale
adapter logic. Generalizes the "integrations" table already scaffolded in
the foundation pass into a working config-in-UI + encrypted-credentials
flow, following the same pattern as the DNS providers module — an
"Add integration" form only offers types with an implemented adapter
(currently just Tailscale), so the framework is ready for the next five
integrations without further schema/plumbing changes.
- server/src/integrations/tailscale/adapter.ts: ported from Sloth Manager's
backend/src/adapters/tailscale.js — listDevices/setAuthorized/deleteDevice
against the Tailscale API, now config-based (tailnet + apiKey) instead of
reading process.env, and returning a ping() result instead of throwing.
- server/src/routes/integrations.ts: generic integration CRUD (admin) + a
"test connection" endpoint, plus Tailscale-specific device routes
(dashboard-and-basic-actions depth per the plan: authorize/deauthorize/
remove, gated to operator+, audit-logged).
- web: an Integrations page (provider-style manage/browse split, matching
the DNS page's UX) with a device table, and a live Tailscale widget on
the Dashboard.
Bug found and fixed while testing: hitting the Tailscale device routes on
a non-Tailscale integration row crashed the ENTIRE server process, not just
that request — the generic adapter registry throws for unimplemented types,
and that throw happened inside an async handler with no surrounding
try/catch, which Express 4 doesn't catch, so it became an unhandled
rejection that (on modern Node) kills the process. Fixed at the source
(check the row's type before ever constructing an adapter) and, since the
same "a helper throws before any local try/catch runs" shape existed
wherever a route calls into loadDnsProviderConfig/loadIntegrationConfig
(both call decryptSecret, which throws if CREDENTIALS_ENCRYPTION_KEY is
ever wrong/missing after data was already encrypted with a different key),
added a small asyncHandler() wrapper and applied it to every route handler
across every router — a single bad request should never be able to take
the whole app down for every user.
Verified: full build passes. Fresh HTTP-layer tests against a running
server (17 checks) cover not-implemented-type rejection, missing-field
validation, a real network call to api.tailscale.com with a bogus key
(clean ok:false, not a crash), role gating at every tier, credential
non-leakage, disabled-integration blocking, and the wrong_type case that
originally crashed the server — confirmed it now returns 400 cleanly and
the server stays up. Re-ran the existing DNS (13 checks) and Servers/Tasks
suites afterward to confirm the asyncHandler sweep didn't regress anything
— all passing. Authorizing/removing a real device still needs a real
Tailscale API key to verify end-to-end.
