Cache a ref with a custom comparator.
Demo
Value: 42
Extra: 0
Cached Value: 42
Cached Extra: 0
Usage
import { useCached } from '@vueuse/core'
interface Data {
value: number
extra: number
}
const source = ref<Data>({ value: 42, extra: 0 })
const cached = useCached(source, (a, b) => a.value === b.value)
source.value = {
value: 42,
extra: 1,
}
console.log(cached.value) // { value: 42, extra: 0 }
source.value = {
value: 43,
extra: 1,
}
console.log(cached.value) // { value: 43, extra: 1 }
import { useCached } from '@vueuse/core'
interface Data {
value: number
extra: number
}
const source = ref<Data>({ value: 42, extra: 0 })
const cached = useCached(source, (a, b) => a.value === b.value)
source.value = {
value: 42,
extra: 1,
}
console.log(cached.value) // { value: 42, extra: 0 }
source.value = {
value: 43,
extra: 1,
}
console.log(cached.value) // { value: 43, extra: 1 }
