Reactivity

BarefootJS uses fine-grained reactivity inspired by SolidJS. For a conceptual overview, see Core Concepts.

All reactive primitives are imported from @barefootjs/dom:

import { createSignal, createEffect, createMemo, onMount, onCleanup, untrack } from '@barefootjs/dom'

#API Reference

API	Description
createSignal	Create a reactive value
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
