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
usePutState. These provide a
MonadStateupdate function rather than a stateID. This is similar to the
useStatein that framework behaves like
useModifyState_here. Use these functions if you only need a single way to update state and prefer more concise code.
useGet- Produce a
getfunction for a value by saving the value in a mutable reference. This function behaves like the
Hooks.getfunction for reading the current state. Most commonly used to get a mutable reference to component
inputso you can read the most up-to-date input when in a callback or effect cleanup.
- Reduce boilerplate when calling
preventDefaulton mouse events and key events.
