Current version supports SQL based migration.

use HHPack\Migrate\Migrator;
use HHPack\Migrate\SqlMigrationLoader;
use HHPack\Migrate\DatabaseClient;

$mysql = await DatabaseClient::createConnection('mysql:dbname=migrate;port=3306', 'migrate', 'migrate');
$loader = new SqlMigrationLoader(__DIR__ . '/sql/migrations');

$migrator = new Migrator($loader, $mysql);

await $migrator->upgrade();

use HHPack\Migrate\Migrator;
use HHPack\Migrate\SqlMigrationLoader;
use HHPack\Migrate\DatabaseClient;

$mysql = await DatabaseClient::createConnection('mysql:dbname=migrate;port=3306', 'migrate', 'migrate');
$loader = new SqlMigrationLoader(__DIR__ . '/sql/migrations');

$migrator = new Migrator($loader, $mysql);

await $migrator->downgrade('20150825102100-create-posts');
