Convert routes using the old, array syntax for options to use Laravel's modern expressive method chains.

Before

Route::post('token', [
    'uses' => 'TokenController@create',
    'as' => 'token.create',
    'middleware' => ['auth', 'throttle:2,1']
]);

After

Route::post('token', 'TokenController@create')
    ->middleware('auth', 'throttle:2,1')
    ->name('token.create');
