# from / fromEvent
|
|
|
|
Wrappers around RxJS's [`from()`](https://rxjs.dev/api/index/function/from) and [`fromEvent()`](https://rxjs.dev/api/index/function/fromEvent) to allow them to accept `ref`s.
|
|
|
|
## Usage
|
|
|
|
<!-- TODO: import rxjs error if enable twoslash -->
|
|
|
|
```ts no-twoslash
|
|
import { from, fromEvent, toObserver, useSubscription } from '@vueuse/rxjs'
|
|
import { interval } from 'rxjs'
|
|
import { map, mapTo, takeUntil, withLatestFrom } from 'rxjs/operators'
|
|
import { shallowRef, useTemplateRef } from 'vue'
|
|
|
|
const count = shallowRef(0)
|
|
const button = useTemplateRef('buttonRef')
|
|
|
|
useSubscription(
|
|
interval(1000)
|
|
.pipe(
|
|
mapTo(1),
|
|
takeUntil(fromEvent(button, 'click')),
|
|
withLatestFrom(from(count, {
|
|
immediate: true,
|
|
deep: false,
|
|
})),
|
|
map(([curr, total]) => curr + total),
|
|
)
|
|
.subscribe(toObserver(count)), // same as ).subscribe(val => (count.value = val))
|
|
)
|
|
```
|
|
|
|
## Type Declarations
|
|
|
|
```ts
|
|
export declare function from<T>(
|
|
value: ObservableInput<T> | Ref<T>,
|
|
watchOptions?: WatchOptions,
|
|
): Observable<T>
|
|
export declare function fromEvent<T extends HTMLElement | null>(
|
|
value: MaybeRef<T>,
|
|
event: string,
|
|
): Observable<Event>
|
|
```
