Utility for creating event hooks
|
|
|
|
## Usage
|
|
|
|
Creating a function that uses `createEventHook`
|
|
|
|
```ts
|
|
import { createEventHook } from '@vueuse/core'
|
|
|
|
export function useMyFetch(url) {
|
|
const fetchResult = createEventHook<Response>()
|
|
const fetchError = createEventHook<any>()
|
|
|
|
fetch(url)
|
|
.then(result => fetchResult.trigger(result))
|
|
.catch(error => fetchError.trigger(error.message))
|
|
|
|
return {
|
|
onResult: fetchResult.on,
|
|
onError: fetchError.on,
|
|
}
|
|
}
|
|
```
|
|
|
|
Using a function that uses `createEventHook`
|
|
|
|
```vue
|
|
<script setup lang="ts">
|
|
import { useMyFetch } from './my-fetch-function'
|
|
|
|
const { onResult, onError } = useMyFetch('my api url')
|
|
|
|
onResult((result) => {
|
|
console.log(result)
|
|
})
|
|
|
|
onError((error) => {
|
|
console.error(error)
|
|
})
|
|
</script>
|
|
```
|
|
|
|
