createBooleanState

Creates a reactive boolean state with convenient methods for boolean operations. Extends createState with boolean-specific helpers like toggle, setTrue, and setFalse.

Example

import type * as React from 'react';
import { createBooleanState } from 'synstate';
import { useObservableValue } from 'synstate-react-hooks';

// Menu drawer open/close state.
// setTrue and setFalse can be passed directly as callbacks
// — no need to create wrapper functions like `() => setState(true)`.
const [menuOpen$, { setTrue: openMenu, setFalse: closeMenu }] =
    createBooleanState(false);

const SampleComponent = (): React.JSX.Element => (
    <MenuDrawer
        open={useObservableValue(menuOpen$)}
        onClose={closeMenu}
        onOpen={openMenu}
    />
);
