@fictjs/use-effect-event

Stable event callback wrapper for Fict, modeled after @radix-ui/react-use-effect-event (React's useEffectEvent). Returns a function with a stable identity that always calls the latest callback — useful for event handlers referenced from effects.

Part of ui-primitives, a port of Radix Primitives to Fict.

Installation

pnpm add @fictjs/use-effect-event fict

Usage

import { prop } from 'fict'
import { useEffectEvent } from '@fictjs/use-effect-event'

const onChange = useEffectEvent<(value: string) => void>(prop(() => props.onChange))
// `onChange` never changes identity, but always invokes the current props.onChange

API

• useEffectEvent(callback) — returns a stable function that forwards to callback. A direct callback is retained as provided; when a parent can replace it, pass a Fict signal, computed value, or prop(() => callback) so each invocation reads the current callback. An undefined current callback is a no-op.

Exports

• Values: useEffectEvent.

Documentation

The API mirrors @radix-ui/react-use-effect-event. See the ui-primitives overview and the architecture guide.
