import {create} from 'tinyjoin';

const db = await create();
await db.exec(`
  CREATE TABLE tasks (id TEXT PRIMARY KEY, title TEXT NOT NULL)
`);
await db.transaction(async (tx) => {
  await tx.query('INSERT INTO tasks (id, title) VALUES ($1, $2)', [
    'a',
    'Write docs',
  ]);
  await tx.rollback();
  console.log(tx.closed);
  // -> true
});

const {rows} = await db.query('SELECT * FROM tasks');
console.log(rows);
// -> []
await db.close();
