Tools for building completely customizable richtext editors with React.

/**
 * Create a selector that updates when an `update` function is called, and
 * which only causes the component to render when the result of `selector`
 * differs from the previous result according to `equalityFn`.
 *
 * If `selector` is memoized using `useCallback`, then it will only be called
 * when it changes or when `update` is called. Otherwise, `selector` will be
 * called every time the component renders.
 *
 * @example
 * const [state, update] = useGenericSelector(selector, equalityFn)
 *
 * useIsomorphicLayoutEffect(() => {
 *   return addEventListener(update)
 * }, [addEventListener, update])
 *
 * return state
