UPGRADE.md

Upgrade from v4 to v5

BREAKING: Promises are based on amphp/amp instead of react/promise

If you have any resolvers waiting for promises using the ->then() method you need to replace these with the yield keyword.

Example:

public function topVotedComment(Article $source, $args, $context, $info)
{
    return $context['loader'](Closure::fromCallable([$this, 'loadComments']))
        ->load($source->id)
        ->then(function ($articleComments) {
            return collect($articleComments)->sortByDesc('votes')->first();
        });
}

to

public function topVotedComment(Article $source, $args, $context, $info)
{
    $comments = yield $context['loader'](Closure::fromCallable([$this, 'loadComments']))
        ->load($source->id);

    return collect($comments)->sortByDesc('votes')->first();
}

BREAKING: The signature of Butler\Graphql\DataLoader@__construct has changed

If you manually instantiate Butler\Graphql\DataLoader anywhere you need to update your code. It's no longer necessary to provide a React\EventLoop\LoopInterface to the constructor.

Example:

$dataLoader = new DataLoader($this->getLoop());

to

$dataLoader = new DataLoader();
