VueUsecreateUnrefFn
Make a plain function accepting ref and raw values as arguments. Returns the same value the unconverted function returns, with proper typing.
TIP
Make sure you're using the right tool for the job. Using reactify might be more pertinent in some cases where you want to evaluate the function on each changes of it's arguments.
Usage
ts
import { ref } from 'vue'
import { createUnrefFn } from '@vueuse/core'
const url = ref('https://httpbin.org/post')
const data = ref({ foo: 'bar' })
const post = (url, data) => fetch(url, { data })
const unrefPost = createUnrefFn(post)
post(url, data) /* ❌ Will throw an error because the arguments are refs */
unrefPost(url, data) /* ✔️ Will Work because the arguments will be auto unref */
import { ref } from 'vue'
import { createUnrefFn } from '@vueuse/core'
const url = ref('https://httpbin.org/post')
const data = ref({ foo: 'bar' })
const post = (url, data) => fetch(url, { data })
const unrefPost = createUnrefFn(post)
post(url, data) /* ❌ Will throw an error because the arguments are refs */
unrefPost(url, data) /* ✔️ Will Work because the arguments will be auto unref */
Type Declarations

? (
...args: {
[K in keyof A]: MaybeRef<A[K]>
}
) => R
: never
/**
