How to add a new column to an existing table in Laravel

This tutorial is How to add a new column to an existing table in Laravel. Here create a migration, you may use the migrate:make command on the Artisan CLI. Use a specific name to avoid clashing with existing models.

php artisan make:migration add_username_to_users_table --table=users

You then need to use the Schema::table() method accessing an existing table, not creating a new one. And you can add a column like this:

#database/migrations/2020_09_16_001052_add_username_to_users_table.php

class AddUsernameToUsersTable extends Migration
{
    public function up()
    {
        Schema::table('users', function($table) {
            $table->string('username');
        });
    }

    public function down()
    {
        Schema::table('users', function($table) {
            $table->dropColumn('username');
        });
    }
}

Now run migrations:

php artisan migrate
