purescript-halogen-hooks-extra

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 shorthand useModifyState_ / useModifyState / usePutState. These provide a MonadState update function rather than a stateID. This is similar to the react-basic-hooks API, where useState in 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 get function for a value by saving the value in a mutable reference. This function behaves like the Hooks.get function for reading the current state. Most commonly used to get a mutable reference to component input 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.
