DatabaseManager

Defined in: src/lib/db/manager.ts:159 

Manages per-wallet WatermelonDB database instances.

Each wallet address gets its own isolated database. The manager handles:

• Singleton caching per wallet
• Automatic database switching when the wallet changes
• Destructive schema migration detection and handling
• Per-wallet storage key namespacing

Example

import { DatabaseManager, webPlatformStorage, sdkSchema, sdkMigrations } from '@reverbia/sdk/react';
import LokiJSAdapter from '@nozbe/watermelondb/adapters/lokijs';
 
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(),
});
 
// Get the database for the current wallet
const database = dbManager.getDatabase(walletAddress);
