Key Changes

1. Automatic PrismaClient Initialization:
   • The Db class now imports @prisma/client and creates a new PrismaClient instance if none is provided in the constructor.
   • This eliminates the need for users to declare const prisma = new PrismaClient() in their code.
2. Database Methods Under db:
   • Removed the #proxyDbMethods function from Indexer.
   • The Db instance is now exposed as indexer.db, allowing calls like indexer.db.save(), indexer.db.modify(), etc.
3. Dependency Update:
   • Added @prisma/client as a direct dependency in package.json since it’s now used internally.
   • Removed it from peerDependencies to simplify installation for users.
4. Simplified Usage:
   • The usage example in the README.md and your provided code no longer requires declaring a PrismaClient.
   • Database methods are accessed via indexer.db, matching your specified syntax.
5. Maintained Flexibility:
   • Users can still provide a custom prismaClient via the options.prismaClient parameter if they need to customize the Prisma client (e.g., with specific configurations).
   • Config customization remains intact via options.config or options.configOverrides.

Updated Usage Example

Your provided usage code is now simplified as follows:

const Indexer = require('my-indexer-package');

async function main() {
  const indexer = new Indexer({
    configOverrides: {
      db: { host: 'production.db.com' },
      proxy: { SPEED_CONFIG: { RATE_LIMIT_DELAY: 1000 } }
    }
  });

  await indexer.start();
  // Output: Indexer started with configuration: { db: { host: 'production.db.com' }, proxy: {...} }
  // Output: Saving data to database at production.db.com...
  // Output: Data saved to the database: { status: 'Indexer started' }

  await indexer.db.save({ data: 'test' });
  // Output: Saving data to database at production.db.com...
  // Output: Data saved to the database: { data: 'test' }

  await indexer.db.modify(1, { data: 'updated' });
  // Output: Modifying data in database at production.db.com...
  // Output: Data modified in the database: { id: 1, data: 'updated' }

  await indexer.db.delete(1);
  // Output: Deleting data from database at production.db.com...
  // Output: Data deleted from the database: 1

  await indexer.db.reset();
  // Output: Resetting database at production.db.com...
  // Output: Database reset.
}

main().catch(console.error);
