# useUIState() function
This API is provided as a preview for developers and may change based on feedback that we receive. Do not use this API in a production environment.
Simple state management for UI purposes.
Signature:
export declare function useUIState(params?: {
stateName?: Ref<string> | string;
}): {
isOpen: ComputedRef<boolean>;
switchState: (to?: boolean) => void;
};
# Parameters
Parameter | Type | Description |
---|---|---|
params | { stateName?: Ref<string> | string; } |
Returns:
{ isOpen: ComputedRef<boolean>; switchState: (to?: boolean) => void; }
# Remarks
If you pase stateName
on composable invocation (ex. useUIState({stateName: 'sidebarCart'})
), then state is shared between all instances with this key. Otherwise state is local, so multiple useUIState()
will not share state
# Example
// Component1
const {isOpen, switchState} = useUIState({stateName: 'SIDEBAR_STATE'})
switchState()
// Component 2
const {isOpen} = useUIState({stateName: 'SIDEBAR_STATE'})
// isOpen will be true
If you'll not use KEY on composable init, then state is only local
// Component1
const {isOpen, switchState} = useUIState()
switchState()
// Component 2
const {isOpen} = useUIState()
// isOpen will be false
