getListenerStats

The getListenerStats method provides a set of statistics about the listeners registered with the Store, and is used for debugging purposes.

getListenerStats(): StoreListenerStats

The StoreListenerStats object contains a breakdown of the different types of listener. Totals include both mutator and non-mutator listeners.

The method is intended to be used during development to ensure your application is not leaking listener registrations, for example.

import {createStore} from 'tinybase';

const store = createStore();
store.addTablesListener(() => console.log('Tables changed'));
store.addRowIdsListener(() => console.log('Row Ids changed'));

const listenerStats = store.getListenerStats();
console.log(listenerStats.rowIds);
// -> 1
console.log(listenerStats.tables);
// -> 1
