Readme
⚽ A collection of ref-related hooks.
import {
useConstant,
useLatest,
usePrevious,
useRefs
} from "https://cdn.skypack.dev/use-referee"
yarn add use-referee
npm install use-referee
useConstant
useConstant<T>(value: Lazy<T>) => T
Given a (lazy) variable, useConstant
will return it as is while never updating or mutating it on subsequent changes.
Import useConstant
.
import { useConstant } from "use-referee"
Declare a constant from an initial (lazy) value.
const id = useConstant(() => uuid())
// id: "123e4567-e89b-12d3-a456-426614174000"
useLatest
useLatest<T>(value: T): MutableRefObject<T>
Given a variable, useLatest
will return a ref which reflects its latest value—mutating itself on variable changes to do so.
Import useLatest
.
import { useLatest } from "use-referee"
Pass it a variable and get a mutating ref of its latest value in return.
const [state, setState] = useState(false)
const latest = useLatest(state)
// latest: { current: false }
Being a ref, latest
will always reflect the latest state
value even when omitted from dependency lists (e.g. []
).
setState(true)
useEffect(() => {
// latest: { current: true }
}, [])
usePrevious
usePrevious<T>(value: T) => T | undefined
Given a variable, usePrevious
will return its previous value or undefined
before an initial change has happened.
Import usePrevious
.
import { usePrevious } from "use-referee"
Pass it a variable and get its previous value in return.
const [state, setState] = useState(false)
const previous = usePrevious(state)
// previous: undefined
setState(true)
// previous: false
setState(false)
// previous: true
useRefs
useRefs<T>(...refs: Ref<T>[]) => RefCallback<T>
Given any number of refs, useRefs
will return a single callback ref that merges them all.
Import useRefs
.
import { useRefs } from "use-referee"
Pass it multiple refs and get a single ref in return.
const refs = useRefs(ref, forwardedRef)
return <div ref={refs} />
// ref: { current: <div /> }
// forwardedRef: { current: <div /> }
