State Persistence in React Maps component

18 Oct 2021 / 1 minute to read

State Persistence

State persistence allows the Maps to retain the current model value in the browser cookies for state maintenance. This action is handled through the enablePersistence property which is set to false by default. When this property is set to true, some of the Maps component model values are preserved even after the page is refreshed.
