Stability: Stable

Core primitive for disclosure/collapsible behavior with deterministic boolean state.

Overview

Use disclosure-core for expandable sections where state is open/closed and framework adapters own rendering.

Installation

npm install @affino/disclosure-core

Quick start

import { DisclosureCore } from "@affino/disclosure-core"

const disclosure = new DisclosureCore(false)

disclosure.open()
disclosure.close()
disclosure.toggle()

const snapshot = disclosure.getSnapshot()
const isOpen = disclosure.isOpen()

Core API

• new DisclosureCore(defaultOpen?)
• open()
• close()
• toggle()
• isOpen()
• getSnapshot()
• subscribe(listener)
• destroy()

Guarantees

• Duplicate open/close calls are no-ops.
• Subscribers are notified only on state transitions.
• getSnapshot() returns frozen immutable values.
• Snapshot reference is stable between no-op operations.

Adapter usage

• Keep one source of truth for disclosure state.
• Bind rendered state directly from snapshots.
• Route manual runtime actions (affino-disclosure:manual) to open/close/toggle in adapter layers.
