For comprehensive React and TanStack patterns including TanStack Query, TanStack Table, TanStack Router, TanStack Form, Next.js App Router, and headless UI abstractions, see:
Pattern Documentation: docs/patterns/react-modern-patterns.md
The patterns include production-ready implementations of:
TanStack Query (React Query)
// Server state management and caching
import { useQuery, useMutation, useQueryClient } from '@tanstack/react-query';
// Complex query patterns
const useVoiceSession = (sessionId: string) => {
return useQuery({
queryKey: ['voice-session', sessionId],
queryFn: () => fetchSession(sessionId),
staleTime: 30_000,
gcTime: 5 * 60_000,
refetchInterval: (query) =>
query.state.data?.status === 'active' ? 5_000 : false,
});
};
// Optimistic updates
const useUpdateTranscript = () => {
const queryClient = useQueryClient();
return useMutation({
mutationFn: updateTranscript,
onMutate: async (newTranscript) => {
await queryClient.cancelQueries({ queryKey: ['transcripts'] });
const previous = queryClient.getQueryData(['transcripts']);
queryClient.setQueryData(['transcripts'], (old) => ({
...old,
...newTranscript,
}));
return { previous };
},
onError: (err, newTranscript, context) => {
queryClient.setQueryData(['transcripts'], context.previous);
},
onSettled: () => {
queryClient.invalidateQueries({ queryKey: ['transcripts'] });
},
});
};
// Infinite queries for pagination
const useTranscriptHistory = () => {
return useInfiniteQuery({
queryKey: ['transcript-history'],
queryFn: ({ pageParam = 0 }) => fetchTranscripts(pageParam),
getNextPageParam: (lastPage) => lastPage.nextCursor,
initialPageParam: 0,
});
};
TanStack Table
// Advanced table implementations
import {
useReactTable,
getCoreRowModel,
getFilteredRowModel,
getSortedRowModel,
getPaginationRowModel,
flexRender,
} from '@tanstack/react-table';
// Reusable table abstraction
function useDataTable<TData>({
data,
columns,
enableSorting = true,
enableFiltering = true,
enablePagination = true,
}: DataTableOptions<TData>) {
return useReactTable({
data,
columns,
getCoreRowModel: getCoreRowModel(),
getFilteredRowModel: enableFiltering ? getFilteredRowModel() : undefined,
getSortedRowModel: enableSorting ? getSortedRowModel() : undefined,
getPaginationRowModel: enablePagination ? getPaginationRowModel() : undefined,
});
}
// Complex column definitions
const columns = [
columnHelper.accessor('timestamp', {
header: 'Time',
cell: (info) => formatTimestamp(info.getValue()),
sortingFn: 'datetime',
}),
columnHelper.accessor('text', {
header: 'Transcript',
cell: (info) => (
<TranscriptCell
text={info.getValue()}
confidence={info.row.original.confidence}
/>
),
enableSorting: false,
}),
columnHelper.display({
id: 'actions',
cell: (props) => <RowActions row={props.row} />,
}),
];
TanStack Router
// Type-safe routing
import { createRouter, createRoute } from '@tanstack/react-router';
const rootRoute = createRootRoute({
component: RootLayout,
});
const sessionRoute = createRoute({
getParentRoute: () => rootRoute,
path: '/session/$sessionId',
component: SessionView,
loader: async ({ params }) => {
const session = await fetchSession(params.sessionId);
return { session };
},
validateSearch: (search) => ({
tab: search.tab as 'transcript' | 'metrics' | undefined,
}),
});
// Type-safe navigation
const navigate = useNavigate();
navigate({
to: '/session/$sessionId',
params: { sessionId: '123' },
search: { tab: 'transcript' }
});
TanStack Form
// Type-safe form handling
import { useForm } from '@tanstack/react-form';
function VoiceSettings() {
const form = useForm({
defaultValues: {
vadSensitivity: 2,
asrModel: 'whisper-small',
ttsVoice: 'piper-lessac',
},
onSubmit: async ({ value }) => {
await updateSettings(value);
},
});
return (
<form
onSubmit={(e) => {
e.preventDefault();
form.handleSubmit();
}}
>
<form.Field
name="vadSensitivity"
validators={{
onChange: ({ value }) =>
value < 0 || value > 3
? 'VAD sensitivity must be between 0 and 3'
: undefined,
}}
>
{(field) => (
<div>
<label htmlFor={field.name}>VAD Sensitivity</label>
<input
id={field.name}
name={field.name}
value={field.state.value}
onChange={(e) => field.handleChange(Number(e.target.value))}
/>
{field.state.meta.errors && (
<em role="alert">{field.state.meta.errors[0]}</em>
)}
</div>
)}
</form.Field>
</form>
);

Adapter Pattern for Library Abstraction
// Abstract away component library specifics

}
// React Aria adapter

Button: AriaButton,
Dialog: AriaDialog,
Select: AriaSelect,
};
// Radix adapter
const radixAdapter: ComponentAdapter = {
Button: RadixButton,
Dialog: RadixDialog,
Select: RadixSelect,
};
// Context-based selection
const ComponentAdapterContext = createContext<ComponentAdapter>(reactAriaAdapter);
// Generic components
function VoiceButton({ children, ...props }: VoiceButtonProps) {
const { Button } = useContext(ComponentAdapterContext);
return <Button {...props}>{children}</Button>;
}
// Easy library swapping
<ComponentAdapterContext.Provider value={radixAdapter}>
<App />
</ComponentAdapterContext.Provider>
Server State (TanStack Query)
// Centralized query configuration
const queryClient = new QueryClient({
defaultOptions: {
queries: {
staleTime: 1000 * 60,
gcTime: 1000 * 60 * 5,
retry: 3,
refetchOnWindowFocus: false,
},
},
});
// Query keys factory
const queryKeys = {
sessions: {
all: ['sessions'] as const,
lists: () => [...queryKeys.sessions.all, 'list'] as const,
list: (filters: SessionFilters) =>
[...queryKeys.sessions.lists(), filters] as const,
details: () => [...queryKeys.sessions.all, 'detail'] as const,
detail: (id: string) => [...queryKeys.sessions.details(), id] as const,
},
transcripts: {
all: ['transcripts'] as const,
bySession: (sessionId: string) =>
[...queryKeys.transcripts.all, sessionId] as const,
},
};
Client State (Zustand with TanStack Query)
import { create } from 'zustand';
import { devtools, persist } from 'zustand/middleware';
interface VoiceStore {
// UI state
isSettingsOpen: boolean;
selectedVoice: string;
vadSensitivity: number;
// Actions

setVoice: (voice) => set({ selectedVoice: voice }),
setVadSensitivity: (level) => set({ vadSensitivity: level }),

React Performance
// Memoization patterns
const MemoizedAudioVisualizer = memo(
AudioVisualizer,
(prev, next) => prev.amplitude === next.amplitude
);
// Expensive computation caching
const processedTranscript = useMemo(() => {
return transcriptSegments
.filter((s) => s.confidence > 0.7)
.map((s) => formatSegment(s));
}, [transcriptSegments]);
// Stable callback references
const handleAudioFrame = useCallback((frame: AudioFrame) => {
// Process frame
}, [/* dependencies */]);
Virtual Scrolling for Large Lists
import { useVirtualizer } from '@tanstack/react-virtual';

transform: `translateY(${virtualRow.start}px)`,
}}
>
<TranscriptSegment segment={segments[virtualRow.index]} />
</div>
))}
</div>
</div>
);
}
Web Workers for Heavy Processing
// Audio processing in worker
const audioWorker = useMemo(
() => new Worker(new URL('./audio-processor.worker.ts', import.meta.url)),
[]
);
useEffect(() => {
audioWorker.onmessage = (e) => {
const { type, data } = e.data;

};
return () => audioWorker.terminate();
}, [audioWorker]);
const processAudio = useCallback((audioData: Float32Array) => {
audioWorker.postMessage({ type: 'process', data: audioData });
}, [audioWorker]);
