Magento setup script – Uninstall

As we already know that Mage 2 also have some uninstall script too!! And the uninstall script is very handy in case we want to remove some tables, columns or data from the root or DB. Hence the uninstall script sweep such a way that the data was not even exist in server site.

In comparison uninstalling is quite different action than disabling. In most cases all of Mage 2 extension should have the uninstall script which is a good practice and suggested. Basically it’ll help to maintain a clean DB without the unwanted extensions. Also it is very useful to clean some specific data from DB tables.

Though today there no such Uninstall scripts whom are available in core modules to test. But regardless of that the pattern is identical.

The Magento setup script for Uninstalling is following:

namespace Aspiration\SetupTest\Setup;

use Magento\Framework\Setup\UninstallInterface;
use Magento\Framework\Setup\SchemaSetupInterface;
use Magento\Framework\Setup\ModuleContextInterface;

class Uninstall implements UninstallInterface
{
public function uninstall(SchemaSetupInterface $setup, ModuleContextInterface $context)
{
$setup->startSetup();

//uninstall code goes here; call table …

$setup->endSetup();
}
}

Here Make a note these script only works with modules installed using Composer.
