- Generic WebSockets (stats, exec) now connect to /ws?nodeId= instead of
the bare root so the upgrade handler detects the remote node and proxies
the WS connection to the correct remote Sencho instance.
- Vite dev proxy gains ws:true on /api and a new /ws entry so WebSocket
upgrades reach localhost:3000 during npm run dev.
- Backend WS message handler falls back to the default local node when the
nodeId in a proxied message doesn't exist in the local DB.
- Open App button now extracts the hostname from the remote node's api_url
instead of using window.location.hostname.
The remoteNodeProxy middleware (line 373) is already positioned before
all API route definitions, so remote requests are correctly proxied to
the target Sencho instance before any route handler executes.
However, /api/system/stats had a dead remote branch that called
NodeRegistry.getDocker() for remote nodes. This method throws by design
("remote nodes are not directly accessible") since no direct Docker TCP
socket is used for remote nodes. The thrown error propagated through the
catch block, returning a 500 to the frontend and causing system stats to
show as loading/unavailable for remote nodes.
Removed the dead branch. Remote requests for /api/system/stats are now
correctly proxied, returning real CPU/RAM/disk data from the remote host.
Adds an ImageUpdateService that queries OCI registry manifest endpoints
every 6 hours to compare remote digests against local RepoDigests.
Results are cached in a new stack_update_status SQLite table. A pulsing
blue dot badge appears in the stack sidebar for stacks with updates
available. Manual refresh available via POST /api/image-updates/refresh
with a 10-minute rate limit.
Two backend fixes:
1. proxyReq was forwarding the browser's sencho_token cookie to the remote
Sencho. The remote's authMiddleware uses cookieToken || bearerToken, so
the invalid local-signed cookie was verified before the valid Bearer token,
returning 401 on every proxied API call. Strip the cookie header in
proxyReq so remote auth uses only the Bearer token.
2. nodeContextMiddleware blocked /api/nodes when x-node-id referenced a
deleted node, trapping the frontend in an unrecoverable 404 loop (it
could not fetch the nodes list to discover the node was gone). Exempt
/api/nodes alongside /api/auth/ so the app can always self-heal.
app.use('/api/', ...) causes Express to strip the '/api/' prefix from
req.url before http-proxy-middleware sees it, so the proxy was forwarding
'/stats' to the remote instead of '/api/stats'. The remote Sencho found
no matching route, fell through to its SPA catch-all, and returned
index.html (200 text/html) — explaining the SyntaxError on res.json().
Added pathRewrite: (path) => '/api' + path to restore the full path.
The connection test passed because testRemoteConnection calls the remote
directly via axios with the full URL, bypassing the proxy entirely.
Add Node modal — type selector & state reset:
- Restored a Local/Remote <Select> dropdown in renderFormFields so users can
explicitly choose the node type instead of it defaulting silently to 'remote'.
- Switching type clears api_url and api_token so no stale remote credentials
carry over if a user switches from Remote to Local mid-form.
- Replaced the static "Add Remote Node" title with a dynamic one that reflects
the currently selected type ("Add Local Node" / "Add Remote Node").
- onOpenChange now resets formData to defaultFormData whenever the dialog
opens, preventing stale values from a previous session leaking in.
Remote connection details — real metrics:
- testRemoteConnection previously returned hard-coded '-' for containers,
images, and cpus after a successful auth/check ping.
- Now fires three parallel requests (Promise.allSettled) after auth passes:
/api/stats → containers total + running count
/api/system/stats → cpu.cores
/api/system/images → image list length
- Each field falls back to '-' gracefully if an endpoint is unavailable,
so a slow or older remote instance never breaks the connection test.
DEP0060 util._extend suppression:
- http-proxy@1.18.1 calls util._extend when createProxyServer() is first
invoked at runtime (NOT at import time). A process.emitWarning override
placed before the proxy instantiations intercepts only DEP0060 without
suppressing any other warnings. No package version changes needed.
Also includes linter/formatter normalisation across multiple files.
Proxy memory leak (MaxListenersExceededWarning + DEP0060):
createProxyMiddleware was instantiated inside the request handler on every
single API call. Each new instance registered fresh 'close' listeners on the
HTTP server and re-ran the http-proxy util._extend deprecated path. After ~10
requests the MaxListeners threshold was breached. Fix: declare ONE global
remoteNodeProxy at startup using the router option to dynamically resolve the
target URL per request. Listeners are registered once. ECONNREFUSED errors are
caught in the on.error handler and returned as structured 502 JSON.
Node switcher "nothing happens":
EditorLayout had a single useEffect([], []) that called refreshStacks() once
on mount. Changing the active node updated NodeContext state and localStorage
but nothing re-triggered the stack list fetch. Fix: split into two effects —
notifications polling (no dependency) and a stack-refresh effect keyed on
activeNode?.id. When the node changes, stale editor/container/file state is
cleared and the stacks for the new node are fetched.
Copy button silently failing:
navigator.clipboard.writeText() throws DOMException in non-HTTPS / non-localhost
contexts (e.g. http://192.168.x.x). The uncaught async exception silently
swallowed the success toast and state update. Fix: wrapped in try/catch with
an execCommand('copy') textarea fallback and a final error toast if both fail.
- Extend WS upgrade handler to accept Authorization: Bearer tokens as a
fallback to cookie auth. Remote Sencho instances receive proxied WS
connections carrying Bearer (no cookie), so the previous cookie-only
check caused immediate 401 rejections for all proxied log/terminal streams.
- Log token validation failures in authMiddleware (was silently swallowed,
violating no-empty-catch directive).
- Normalize api_url by stripping trailing slashes in testRemoteConnection,
the HTTP proxy target, and the WS proxy target to prevent double-slash URLs.
Remote nodes in the Distributed API model are self-monitoring — each
remote Sencho instance runs its own MonitorService against its local
Docker socket. The main instance must not attempt direct DockerController
access for remote nodes, which caused fatal crashes on every 30s tick.

Eliminates massive false-positive error misclassifications caused by Docker
containers writing standard INFO logs to STDERR. The new hierarchy:
1. INFO/DEBUG/TRACE indicators (overrides STDERR default)
2. WARN/WARNING indicators
3. ERROR/FATAL/CRIT/CRITICAL/PANIC + Exception: indicators
Supports common log formats: level=info, [INFO], and bare INFO tokens.
Applied to both /api/logs/global and /api/logs/global/stream endpoints.
