README

Sidecar package for t3n/graphql that brings an Upload scalar and enables you to handle file uploads in your schema.

Simply install the package via composer:

composer require t3n/graphql-upload

Configuration

This package ships all needed parts. However, you must add the typeDefs and the Resolver to your schema like this:

t3n:
  GraphQL:
    endpoints:
      'your-endpoint': #use your endpoint variable here
        schemas:
          upload:
            typeDefs: 'resource://t3n.GraphQL.Upload/Private/GraphQL/schema.upload.graphql'
            resolvers:
              Upload: 't3n\GraphQL\Upload\Resolver\Type\UploadResolver'

This is everything you need to do. Once configured you can use the Upload scalar in your app.

Usage

To use the Upload scalar you might want to add it as an arg to a mutation like this:

type Mutation {
    uploadFile(file: Upload): String
}

This package will handle the upload itself and pass an Neos\Http\Factories\FlowUploadedFile to your MutationResolver. Within your resolver method your could for instance import your resource:

class MutationResolver implements ResolverInterface
{
    /**
     * @Flow\Inject
     *
     * @var ResourceManager
     */
    protected $resourceManager;

    public function uploadFile($_, $variables): string
    {
        /** @var FlowUploadedFile $file */
        $file = $variables['file'];

        $resource = $this->resourceManager->importResource($file->getStream()->detach());
        $resource->setFilename($file->getClientFilename());
        $resource->setMediaType($file->getClientMediaType());

        return $file->getClientFilename();
    }
}

Some notes

To actually use file upload your frontend client must use multipart/form-data in your forms. This Package is tested with a react app that uses https://github.com/jaydenseric/apollo-upload-client
