MigrationInterface#

Meritum\Migrations\MigrationInterface

The contract every migration must implement. Each migration file returns an anonymous class that implements this interface.

Methods#

public function up(SchemaInterface $schema): void;

Applied when the migration is run. Use $schema to create or alter tables.

public function down(SchemaInterface $schema): void;

Applied when the migration is rolled back. Should reverse everything done in up().

Example#

<?php

use Georgeff\Schema\Blueprint;
use Meritum\Migrations\SchemaInterface;
use Meritum\Migrations\MigrationInterface;

return new class implements MigrationInterface {

    public function up(SchemaInterface $schema): void
    {
        $schema->create('posts', function (Blueprint $blueprint) {
            $blueprint->uuid('id')->unique()->primary();
            $blueprint->string('title');
            $blueprint->text('body');
            $blueprint->timestamps();
        });
    }

    public function down(SchemaInterface $schema): void
    {
        $schema->dropIfExists('posts');
    }
};
