README

Symfony bundle for easy implementation images to your GraphQL API ( bundle with GraphQL implementation and its documentation is here ). Bundle provides UploadImageMutation:

mutation {
  uploadImage(field: "image") {
    id
    url
    resized(width: 100, height: 100, mode: INSET) {
      url
    }
  }
}

Mutation assumes that request content-type is multipart/form-data and include image data in field that is passed as argument field. Also bundle provides ImageField to use in your API like this:

{
  me {
    id
    firstName
    lastName
    image { // image field from bundle
      url
      resized(width: 100, height: 100, mode: INSET) {
        url
      }
    }
  }
}

or you can add arguments directly to the image field for your convenience.

{
  me {
    id
    firstName
    lastName
    small: image(width: 100, height: 100, mode: INSET) { // resized directly
      url
    }    
    medium: image(width: 500, height: 300, mode: OUTBOUND) { // different mode
      url
    }    
    fullSize: image {
      url
    }
  }
}

How to use

• Installation
• Configuration
• Entity set-up
  • ORM way
  • ODM way
• GraphQL schema set-up
  • Mutation type
  • Custom type
  • Resolver

1. Installation:

composer require youshido/api-images

2. Configuration:

2.1 Enable bundle in your AppKernel.php:

$bundles[] = new Youshido\ImagesBundle\ImagesBundle()

2.2. Add new routing in routing.yml:

images:
    resource: "@ImagesBundle/Controller/"
    type:     annotation

2.3. Configurate bundle in config.yml

images:
    web_root: "%kernel.root_dir%/../web" #your app web root
    path_prefix: "uploads/images"        #folder in web root where images will be stored
    platform: orm                        #orm or odm
    driver: gd                           #imagine driver, can be gd, imagick or gmagick

3 Set-up your entities

3.1 ORM set-up

Add image property and implement ImageableInterface to your entity:

<?php

use Youshido\ImagesBundle\Entity\Interfaces\ImageableInterface;

/**
 * @ORM\Entity
 */
class YourEntity implements ImageableInterface
{

    // other your properties

  /**
   * @var Image
   *
   * @ORM\ManyToOne(targetEntity="Youshido\ImagesBundle\Entity\Image")
   */
  private $image;

  /**
   * @return Image
   */
  public function getImage()
  {
      return $this->image;
  }

  /**
   * @param Image $image
   *
   * @return User
   */
  public function setImage(Image $image = null)
  {
      $this->image = $image;

      return $this;
  }

3.2 ODM set-up

Use ImageableTrait and implement ImageableInterface to your entity:

<?php

use Youshido\ImagesBundle\Document\Interfaces\ImageableInterface;
use Youshido\ImagesBundle\Document\Traits\ImageableTrait;

/**
 * @MongoDB\Document()
 */
class Category implements ImageableInterface
{

    use ImageableTrait;

    //other properties

4. Set-up GraphQL schema:

4.1 Add UploadImageMutation to your MutationType:

<?php

use Youshido\ImagesBundle\GraphQL\Field\Mutation\UploadImageField;

class MutationType extends AbstractObjectType
{

    public function build($config)
    {

        $config->addFields([
            new UploadImageField(),

            // other mutations
        ]);

    }
}

4.2 Add image field to your type:

use Youshido\ImagesBundle\GraphQL\Field\Query\ImageField;

class CategoryType extends AbstractObjectType
{

    public function build($config)
    {
        $config->addFields([
            // category fields
        
            new ImageField()
        ]);
    }

}

4.3 Set/update image in your field resolver:

//for odm
$image = $dm->getRepository(Image::class)->find($imageId);
$yourEntity->setImage($image ? new EmbeddedImage($image) : null);

//for orm
$image = $em->getRepository(Image::class)->find($imageId);
$yourEntity->setImage($image);
