Getting Started

import 'package:calljmp/calljmp.dart';

final calljmp = Calljmp();

// Type-safe database operations
final users = await calljmp.database.query(
  sql: 'SELECT * FROM users WHERE age > ?',
  params: [21],
);

// Real-time database subscriptions
final subscription = await calljmp.database.observe<User>('users.insert')
  .onInsert((event) {
    print('New users: ${event.rows}');
  })
  .filter(DatabaseGtFilter('age', 18))
  .subscribe();

// Real-time pub/sub messaging
final rtSubscription = await calljmp.realtime.observe<Message>('chat.room1')
  .onData((event) {
    print('Message: ${event.data}');
  })
  .filter(RealtimeEqFilter('room_id', 'room123'))
  .subscribe();
