Reactivity

All reactive primitives are imported from @barefootjs/client:

"use client"
import { createSignal, createEffect, createMemo, onMount, onCleanup, untrack, batch } from '@barefootjs/client'

#API Reference

createEffect	Run side effects when dependencies change
createMemo	Create a cached derived value
onMount	Run once on component initialization
onCleanup	Register cleanup for effects and lifecycle
untrack	Read signals without tracking dependencies
batch	Group signal writes so subscribers run once
