Thin wrapper around useRef. Creates a ReactRef
of the initialValue
passed in.
ReactRef
ReactRef
object that has the following properties
get()
: returns current value of the Ref.set(newValue)
: updates the current value of the Ref to the newValue.reset()
: resets the current value to the initialValue
passed in.isInitialValue()
: returns true
if current value is the initialValue
passed in. false
otherwise.isEqual(otherValue)
: returns true
if current value is equal to otherValue
. false
otherwise.ref
: underlying useRef
return value MutableRefObject
.You should only use .ref
if another library needs the MutableRefObject
.
Thin wrapper around useState. Creates a ReactState
of the initialValue
passed in.
ReactState
ReactState
object that has the following properties
value
: currentValue of the ReactState
.set(newValue)
: updates the state on next render to the newValue
and triggers a rerender.reset()
: resets the value on next render to the initialValue
passed in and triggers a rerender.isInitialValue()
: returns true
if value is the initialValue
passed in. false
otherwise.isEqual(otherValue)
: returns true
if value is equal to otherValue
. false
otherwise.We have included createStubReactRef
and createStubReactState
to help with unit tests around components that are
being passed these as props.
To hook it up with a tool like jest. Here is how you would wrap the simple stub provided.
import { createStubReactState } from 'use-react-ref';
export function createSpyReactState<T>(value: T, set: SetValueType<T> = jest.fn()): ReactState<T> {
return createStubReactState(value, set)
}
