Consolidate 5 stat mapper useCallbacks and 6 series useMemos into
single mappers/series objects. Extract statsWhenShown helper for
repeated visibility guard pattern. Deduplicate SSE record envelope
construction. Simplify prepareRecords with if/else. Remove unused
gridColumns ternary with Number() indexing.
Replace all ternary operators with if/else, &&/||, or early returns.
Remove unused noAnimation constant that caused lint error.
Fix variable shadowing in tooltip deduplication loop.
- Decouple 1Hz SSE ingestion from render rate: accumulate data in a
ref and flush to React state every 3s instead of every tick
- First data point flushes immediately to avoid blank screen
- Reduce MAX_BUFFER from 60 to 30 (halves SVG reconciliation work)
- Gate chart data hooks behind visibility flags so disabled charts
skip all array processing
Keep showing existing charts during brief WebSocket reconnections
instead of flashing the error UI. The error state only shows when
no data was ever received (genuine initial connection failure).
- Set withDots={false} to eliminate thousands of hidden SVG Dot nodes
- Disable Recharts animation (isAnimationActive: false) during data updates
- Merge ChartPanel + BeszelAreaChart into BeszelChartPanel to fix
React.memo being defeated by children prop creating new refs
- Memoize yAxisProps inside BeszelAreaChart instead of rebuilding inline
- Hoist chartStyle, panelStyle, CPU_Y_AXIS_DOMAIN to module constants
- Memoize subscription input/enabled in useLiveStats
- Replace O(n) find() with Map lookup in useDockerChartData hot path
- Stabilize useContainerNames with ref comparison so it returns the
same array reference when container names haven't changed
- Memoize containerSeries (was computed inline every render)
- Hoist all system chart series arrays into useMemo
- Hoist activeDotProps/dotProps to module-level constants
- Wrap BeszelAreaChart and ChartPanel in React.memo
When SSE connection fails, the error UI now shows a specific message
and a button to switch back to historical view, so users don't need
to reload the page to recover.
- Restore timePeriod union cast to fix typecheck (TS2769)
- Clear live data on subscription error so error UI always shows
- Emit error when no integration is configured for live subscription
- Add error state to system select input when query fails
- Surface subscription errors in useLiveStats via onError + error state
- Show error UI in live mode when SSE connection fails
- Abort SSE reader on subscribeTopic failure instead of silent log
- Guard mock realtime against pre-aborted signal to prevent interval leak
- Remove dead includeDocker from subscription input schema
- Gate stats/live queries on systems loading state to prevent stale ID
requests during initial load
- Simplify useLiveStats: functional setState, stable integrationKey dep,
remove unused includeDocker param
- Extract prepareRecords helper to deduplicate chart ordering logic
- Remove stale timePeriod type cast
Replace plain text systemId option with a dedicated beszelSystem factory
type backed by a searchable Select that fetches available systems from
the integration. Shows proper states for no integration, loading, and
no systems found.
- Skip toReversed() for live data (already chronological from buffer)
- Reset live buffer on systemId/integration change to avoid stale data
- Throw on unexpected SSE stream end so subscription emits error
- Delete unused time-period.ts config (duplicate of server-side config)
Add "Live" option to time period selector that uses the existing
subscribeSystemStats tRPC subscription (PocketBase SSE) instead of
REST polling. A useLiveStats hook accumulates incoming data points
in a 60-entry rolling buffer. Charts use HH:mm:ss timestamps in
live mode.
- Add subscribeSystemStats tRPC subscription bridging PocketBase SSE
- Add subscribeRealtimeMetrics to BeszelIntegration with SSE parsing
- Add error handling: try/catch in subscription, response check in topic POST
- Add cacheDurationForInput to request handler for per-period cache TTL
- Add mock subscribeRealtimeMetrics with 1s interval for dev testing
Non-stacked charts produce duplicate Recharts payload entries (stroke +
fill). Deduplicate by dataKey keeping the first entry (correct color).
Also increase indicator borderRadius for a fully rounded pill.
BeszelAreaChart hardcoded type="stacked" for all charts, causing Docker
Network I/O to render blended colors that didn't match the tooltip.
- Make `type` prop configurable (default "default")
- Only stack Memory, Docker CPU, and Docker Memory charts
- Add systemId as a persisted widget option with Menu-based selector
- Replace Popover with Menu trigger="click-hover" for proper hover UX
- Show error state with Select when selected system is not found
- Remove 1-minute time period (live SSE not wired yet)
The postinstall codegen script crashes CI when homarr.dev/sitemap.xml
is unreachable. Now catches fetch errors and keeps the existing
committed homarr-docs-sitemap.ts instead of crashing.
