$dbal = new Database\DatabaseManager(new Config\DatabaseConfig([
    'default' => 'default',
    'databases' => [
        'default' => [
            'connection' => 'sqlite'
        ]
    ],
    'connections' => [
        'sqlite' => new Config\SQLiteDriverConfig(
            connection: new Config\SQLite\MemoryConnectionConfig(),
            queryCache: true,
        ),
    ]
]));

$config = new Migrations\Config\MigrationConfig([
    'directory' => __DIR__ . '/../migrations/',    // where to store migrations
    'vendorDirectories' => [                       // Where to look for vendor package migrations
        __DIR__ . '/../vendor/vendorName/packageName/migrations/'
    ],
    'table' => 'migrations'                       // database table to store migration status
    'safe' => true                                // When set to true no confirmation will be requested on migration run. 
]);

$migrator = new Migrations\Migrator(
    $config, 
    $dbal, 
    new Migrations\FileRepository($config)
);

// Init migration table
$migrator->configure();

Running

while (($migration = $migrator->run()) !== null) {
    echo 'Migrate ' . $migration->getState()->getName();
}

Generate Migrations

You can automatically generate a set of migration files during schema compilation. In this case, you have the freedom to alter such migrations manually before running them. To achieve that you must install the Cycle migrations extension.
