VEF Hooks

useAuthorizedItems​

Filters config arrays by permission metadata.

useBreakpoints​

Returns breakpoint state from a custom breakpoint configuration.

useCheckPermission​

Returns a reusable function for imperative permission checks.

useDataDictQuery​

Fetches data-dictionary options through appContext.dataDictQueryFn.

useDataOptionsQuery​

Transforms query or dictionary data into normalized option structures, including pinyin-enhanced variants when needed.

Deep / Shallow Comparison Hooks​

These hooks help when dependency arrays contain objects or arrays and default shallow reference checks are not enough:

  • useDeepCallback
  • useDeepCompare
  • useDeepEffect
  • useDeepIsomorphicEffect
  • useDeepLayoutEffect
  • useDeepMemo
  • useShallowCallback
  • useShallowCompare
  • useShallowEffect
  • useShallowIsomorphicEffect
  • useShallowLayoutEffect
  • useShallowMemo

Event and Environment Hooks​

Representative hooks in this group:

  • useDocumentEvent
  • useEmitterEvent
  • useLatest
  • useRafState
  • useSingleton
  • useViewportSize

Query and Mutation State Hooks​

  • useHasFetching
  • useHasMutating

These are especially useful for page-level loading coordination and disabling repeated actions while requests are running.
