Provides useful Halogen Hooks and other utilities commonly used in hooks (e.g. actions).
useDebouncer
- run an action only when a specified amount of time has passed without receiving any new updats/values (e.g. search the database using user's query after 300 ms of no input).useThrottle
- run an action with the next value after ignoring new values for a specified amount of time (e.g. handle 1 scroll event every 300 ms).useEvent
- run a callback whenever a new value is pushed (e.g. allow a library to publish events within it to end-users of the library).- Convenience function
useStateFn
and shorthanduseModifyState_
/useModifyState
/usePutState
. These provide aMonadState
update function rather than a stateID. This is similar to thereact-basic-hooks
API, whereuseState
in that framework behaves likeuseModifyState_
here. Use these functions if you only need a single way to update state and prefer more concise code. useGet
- Produce aget
function for a value by saving the value in a mutable reference. This function behaves like theHooks.get
function for reading the current state. Most commonly used to get a mutable reference to componentinput
so you can read the most up-to-date input when in a callback or effect cleanup.
- Reduce boilerplate when calling
preventDefault
on mouse events and key events.
