debounce()

Delays each upstream change by ms; resets the timer if another value arrives sooner (leading-edge cancel).

Signature

function debounce<A>(ms: number): StoreOperator<A, A | undefined>

Parameters

Parameter	Type	Description
ms	number	Debounce interval in milliseconds.

Returns

StoreOperator<A, A | undefined> — undefined until the first debounced emission; flushes pending on upstream complete.

Basic Usage

import { state, pipe } from 'callbag-recharge';
import { debounce } from 'callbag-recharge/extra';

const q = state('');
const d = pipe(q, debounce(100));
q.set('hi');
// after 100ms idle, d emits 'hi'

Options / Behavior Details

• Tier 2: Cycle boundary; each debounced emit is its own DIRTY+DATA cycle.
• Errors: Cancels the timer and forwards upstream errors.
