useDatabaseManager

useDatabaseManager(walletAddress: string | undefined, manager: DatabaseManager): Database

Defined in: src/react/useDatabaseManager.ts:49

React hook that returns the correct WatermelonDB Database instance for the current wallet address.

Replaces the common pattern of:


const database = useMemo(() => getWatermelonDatabase(walletAddress), [walletAddress]);

When the wallet address changes, a new database instance is returned, providing complete per-wallet data isolation.

Parameters

Parameter	Type	Description
`walletAddress`	`string` \| `undefined`	The current user’s wallet address, or undefined for guest mode
`manager`	`DatabaseManager`	A DatabaseManager instance (should be created once at app level)

Returns

Database

The WatermelonDB Database instance for the current wallet

Example


import { useDatabaseManager, DatabaseManager, webPlatformStorage } from '@reverbia/sdk/react';
import LokiJSAdapter from '@nozbe/watermelondb/adapters/lokijs';
 
// Create once at app level
const dbManager = new DatabaseManager({
  dbNamePrefix: 'my-app',
  createAdapter: (dbName, schema, migrations) => new LokiJSAdapter({
    schema, migrations, dbName,
    useWebWorker: false,
    useIncrementalIndexedDB: true,
  }),
  storage: webPlatformStorage,
  onDestructiveMigration: () => window.location.reload(),
});
 
function MyComponent() {
  const { user } = usePrivy();
  const database = useDatabaseManager(user?.wallet?.address, dbManager);
 
  // Pass database to SDK hooks
  const { sendMessage } = useChatStorage({ database, ... });
