New Features

Live Queries 🎉

For a full explanation about Drizzle + Expo welcome to discussions

As of v0.31.1 Drizzle ORM now has native support for Expo SQLite Live Queries! We’ve implemented a native useLiveQuery React Hook which observes necessary database changes and automatically re-runs database queries. It works with both SQL-like and Drizzle Queries:

import { useLiveQuery, drizzle } from 'drizzle-orm/expo-sqlite';
import { openDatabaseSync } from 'expo-sqlite/next';
import { users } from './schema';
import { Text } from 'react-native';

const expo = openDatabaseSync('db.db', { enableChangeListener: true }); // <-- enable change listeners
const db = drizzle(expo);

const App = () => {
  // Re-renders automatically when data changes
  const { data } = useLiveQuery(db.select().from(users));

  // const { data, error, updatedAt } = useLiveQuery(db.query.users.findFirst());
  // const { data, error, updatedAt } = useLiveQuery(db.query.users.findMany());


  return <Text>{JSON.stringify(data)}</Text>;
};

export default App;

We’ve intentionally not changed the API of ORM itself to stay with conventional React Hook API, so we have useLiveQuery(databaseQuery) as opposed to db.select().from(users).useLive() or db.query.users.useFindMany()

We’ve also decided to provide data, error and updatedAt fields as a result of hook for concise explicit error handling following practices of React Query and Electric SQL
