What is the structure of a Laravel migration?

A Laravel migration typically consists of a class that extends the Migration class, with two main methods: up() and down(). The up() method is used to define the changes to be made to the database, while the down() method reverses those changes.

Can you give me an example of a migration?

Sure! Here's a simple example:

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Schema;

class CreateUsersTable extends Migration {
    public function up() {
        Schema::create('users', function (Blueprint $table) {
            $table->id();
            $table->string('name');
            $table->string('email')->unique();
            $table->timestamps();
        });
    }

    public function down() {
        Schema::dropIfExists('users');
    }
}

What does the Blueprint class do in this context?

The Blueprint class is used to define the structure of the database table. It provides methods to add columns, indexes, and foreign keys, allowing you to easily specify the schema of your table.

How do I run a migration after creating it?

You can run a migration using the Artisan command line tool. Simply execute php artisan migrate in your terminal, and it will apply all pending migrations.
