State persistence in React Query builder component

30 Jan 20235 minutes to read

State persistence allows you to maintain the current state in the browser’s localStorage even if the browser is refreshed or if you move to the next page within the browser. State persistence stores the Query Builder’s rule object in the local storage when the enablePersistence is defined to true.
