useResizeObserver reads ref.current at render time; on page refresh with
fast SWR cache, no re-render occurs after mount so ref.current remains null
in the effect, observation never starts, and containerWidth stays 0 forever.
Add a useLayoutEffect that measures offsetWidth synchronously before paint
as a seed value (effectiveWidth = containerWidth || initialWidth). Once
ResizeObserver fires normally, containerWidth takes over. The Responsive
grid is gated on effectiveWidth > 0 so it always renders correctly on both
first load and refresh.

Gate <Responsive> rendering on containerWidth > 0 so it only mounts after
ResizeObserver has measured the container. Use availableWidth directly as
the width prop (no window.innerWidth fallback) since the component now only
renders when containerWidth is known. This prevents the grid from rendering
wider than its container (which caused the rightmost column to overflow the
right edge).
https://claude.ai/code/session_01H1sqbcFmtwwsdNTJcJHJWd
availableWidth starts at 0 (not null/undefined) before ResizeObserver fires.
The ?? operator passes 0 through instead of falling back to window.innerWidth,
making cellHeight negative and causing react-grid-layout to render a ~10px
container. The overflow-x-hidden div then becomes an implicit scroll container,
producing the 'cards squeezed in a small rectangle' symptom.
Changing ?? to || makes 0 trigger the window.innerWidth fallback, giving a
reasonable initial rowHeight until the real container width is measured.

Grid tiles explicitly set --frigate-mse-object-fit:fill so video stretches
to fill the card without preserving aspect ratio. The MsePlayer default
is contain, so History preview and all other contexts keep correct proportions.

* dynamic ffmpeg
* ensure previews dir exists
when ffmpeg processes restart, there's a brief window where the preview frame generation pipeline is torn down and restarted. before these changes, ffmpeg only restarted on crash/stall recovery or full Frigate restart. Now that ffmpeg restarts happen on-demand via config changes, there's a higher chance a frontend request hits the preview_mp4 or preview_gif endpoints during that brief restart window when the directory might not exist yet. The existing os.listdir() call would throw FileNotFoundError without a directory existence check. this fix just checks if the directory exists and returns 404 if not, exactly how preview_thumbnail already handles the same scenario a few lines below

- use-overlay-state: use refs for location to keep setter identity
stable across renders, preventing cascading re-render loops when
effects depend on the setter. Add Object.is bail-out guard to skip
redundant navigate calls. Move setPersistedValue after bail-out to
avoid unnecessary IndexedDB writes.
* don't try to fetch previews when motion search dialog is open
* revert unneeded changes
re-rendering was caused by the overlay state hook, not this one
* filter dicts to only use id field in sync recordings
* remove unused RecoilRoot and fix implicit ref callback
Remove the vestigial recoil dependency (zero consumers) and convert
the implicit-return ref callback in SearchView to block form to
prevent React 19 interpreting it as a cleanup function.
* replace react-transition-group with framer-motion in Chip
Replace CSSTransition with framer-motion AnimatePresence + motion.div
for React 19 compatibility (react-transition-group uses findDOMNode).
framer-motion is already a project dependency.
* migrate react-grid-layout v1 to v2
- Replace WidthProvider(Responsive) HOC with useContainerWidth hook
- Update types: Layout (single item) → LayoutItem, Layout[] → Layout
- Replace isDraggable/isResizable/resizeHandles with dragConfig/resizeConfig
- Update EventCallback signature for v2 API
- Remove @types/react-grid-layout (v2 includes its own types)
* upgrade vaul, next-themes, framer-motion, react-zoom-pan-pinch
- vaul: ^0.9.1 → ^1.1.2
- next-themes: ^0.3.0 → ^0.4.6
- framer-motion: ^11.5.4 → ^12.35.0 (React 19 native support)
- react-zoom-pan-pinch: 3.4.4 → latest
* upgrade to React 19, react-konva v19, eslint-plugin-react-hooks v5
Core React 19 upgrade with all necessary type fixes:
- Update RefObject types to accept T | null (React 19 refs always nullable)
- Add JSX namespace imports (no longer global in React 19)
- Add initial values to useRef calls (required in React 19)
- Fix ReactElement.props unknown type in config-form components
- Fix IconWrapper interface to use HTMLAttributes instead of index signature
- Add monaco-editor as dev dependency for type declarations
- Upgrade react-konva to v19, eslint-plugin-react-hooks to v5
* upgrade typescript to 5.9.3
* modernize Context.Provider to React 19 shorthand
Replace <Context.Provider value={...}> with <Context value={...}>
across all project-owned context providers. External library contexts
(react-icons IconContext, radix TooltipPrimitive) left unchanged.
* add runtime patches for React 19 compatibility
- Patch @radix-ui/react-compose-refs@1.1.2: stabilize useComposedRefs
to prevent infinite render loops from unstable ref callbacks
https://github.com/radix-ui/primitives/issues/3799
- Patch @radix-ui/react-slot@1.2.4: use useComposedRefs hook in
SlotClone instead of inline composeRefs to prevent re-render cycles
https://github.com/radix-ui/primitives/pull/3804
- Patch react-use-websocket@4.8.1: remove flushSync wrappers that
cause "Maximum update depth exceeded" with React 19 auto-batching
https://github.com/facebook/react/issues/27613
- Add npm overrides to ensure single hoisted copies of compose-refs
and react-slot across all Radix packages
- Add postinstall script for patch-package
- Remove leftover react-transition-group dependency
* formatting
* use availableWidth instead of useContainerWidth for grid layout
The useContainerWidth hook from react-grid-layout v2 returns raw
container width without accounting for scrollbar width, causing the
grid to not fill the full available space. Use the existing
availableWidth value from useResizeObserver which already compensates
for scrollbar width, matching the working implementation.
* remove unused carousel component and fix React 19 peer deps
Remove embla-carousel-react and its unused Carousel UI component.
Upgrade sonner v1 → v2 for native React 19 support. Remove
@types/react-icons stub (react-icons bundles its own types).
These changes eliminate all peer dependency conflicts, so
npm install works without --legacy-peer-deps.
* fix React 19 infinite re-render loop on live dashboard
The "Maximum update depth exceeded" error was caused by two issues:
1. useDeferredStreamMetadata returned a new `{}` default on every render
when SWR data was undefined, creating an unstable reference that
triggered the useEffect in useCameraLiveMode on every render cycle.
Fixed by using a stable module-level EMPTY_METADATA constant.
2. useResizeObserver's rest parameter `...refs` created a new array on
every render, causing its useEffect to re-run and re-observe elements
continuously. Fixed by stabilizing refs with useRef and only
reconnecting the observer when actual DOM elements change.

Cameras that have `ui.dashboard = false` config are hidden from
the All Cameras "default" group, but their alerts still appear in the
top row. This hides the alerts as well.
One can still view the hidden cameras and their alerts by making a
custom camera group.
