watchWithFilter

可以传入EventFilter来控制watch

用法

类似于watch,但提供了一个将应用于回调函数的额外选项eventFilter

ts
import { debounceFilter, watchWithFilter } from '@mpxjs/mpxuse-core'

watchWithFilter(
  source,
  () => { console.log('changed!') }, // callback will be called in 500ms debounced manner
  {
    eventFilter: debounceFilter(500), // throttledFilter, pausabledFilter or custom filters
  },
)
import { debounceFilter, watchWithFilter } from '@mpxjs/mpxuse-core'

watchWithFilter(
  source,
  () => { console.log('changed!') }, // callback will be called in 500ms debounced manner
  {
    eventFilter: debounceFilter(500), // throttledFilter, pausabledFilter or custom filters
  },
)

类型声明

typescript
export interface WatchWithFilterOptions
  extends WatchOptions,
    ConfigurableEventFilter {}
export declare function watchWithFilter<
  T extends Readonly<WatchSource<unknown>[]>,
  Immediate extends Readonly<boolean> = false
>(
  sources: [...T],
  cb: WatchCallback<MapSources<T>, MapOldSources<T, Immediate>>,
  options?: WatchWithFilterOptions
): WatchStopHandle
export declare function watchWithFilter<
  T,
  Immediate extends Readonly<boolean> = false
>(
  source: WatchSource<T>,
  cb: WatchCallback<T, Immediate extends true ? T | undefined : T>,
  options?: WatchWithFilterOptions
): WatchStopHandle
export declare function watchWithFilter<
  T extends object,
  Immediate extends Readonly<boolean> = false
>(
  source: T,
  cb: WatchCallback<T, Immediate extends true ? T | undefined : T>,
  options?: WatchWithFilterOptions
): WatchStopHandle
export interface WatchWithFilterOptions
  extends WatchOptions,
    ConfigurableEventFilter {}
export declare function watchWithFilter<
  T extends Readonly<WatchSource<unknown>[]>,
  Immediate extends Readonly<boolean> = false
>(
  sources: [...T],
  cb: WatchCallback<MapSources<T>, MapOldSources<T, Immediate>>,
  options?: WatchWithFilterOptions
): WatchStopHandle
export declare function watchWithFilter<
  T,
  Immediate extends Readonly<boolean> = false
>(
  source: WatchSource<T>,
  cb: WatchCallback<T, Immediate extends true ? T | undefined : T>,
  options?: WatchWithFilterOptions
): WatchStopHandle
export declare function watchWithFilter<
  T extends object,
  Immediate extends Readonly<boolean> = false
>(
  source: T,
  cb: WatchCallback<T, Immediate extends true ? T | undefined : T>,
