Paragraphs weight delta

Yeah lets do it. I’ll try get it done tomorrow and into dev.

OOooohkay!
Hopefully this is enough information for you:

I've updated the docs to help with your query:
https://drupal-graphql-compose.github.io/documentation/#/extending/custo...

This is possible using hooks in a custom module on your end.

I'm hesitant to add it to the schema, as the data doesn't really exist and isn't a schema requiremen... The return order of the data is the same as the delta. So you use case might be a little unique in the need for it to be in the data.

What you want though, is 100% possible, just using a few hooks.

/**
 * @file
 * My drupal module that extends graphql_compose.
 */

declare(strict_types=1);

use Drupal\Core\Cache\RefinableCacheableDependencyInterface;
use Drupal\Core\Entity\EntityTypeInterface;
use Drupal\Core\Field\BaseFieldDefinition;
use Drupal\paragraphs\ParagraphInterface;

/**
 * Implements hook_entity_base_field_info().
 *
 * Add a weight field to paragraphs.
 */
function mymodule_entity_base_field_info(EntityTypeInterface $entity_type): ?array {
  if ($entity_type->id() === 'paragraph') {
    $fields = [];
    $fields['weight'] = BaseFieldDefinition::create('integer')
      ->setLabel(t('Weight'))
      ->setDescription(t('The delta weight of this paragraph within a fielded context.'))
      ->setComputed(TRUE)
      ->setDefaultValue(0);
    return $fields;
  }
}

/**
 * Implements hook_graphql_compose_field_results_alter().
 *
 * Modify the entity results as they are given to the schema.
 *
 * You could also compute this somewhere else, but for this example
 * we'll do it here.
 *
 * The delta is the position of the paragraph in the field.
 */
function mymodule_graphql_compose_field_results_alter(array &$results, array $context, RefinableCacheableDependencyInterface $metadata): void {
  foreach ($results as $delta => $result) {
    if ($result instanceof ParagraphInterface) {
      $result->set('weight', $delta ?? 0);
    }
  }
}

/**
 * Implements hook_graphql_compose_entity_base_fields_alter().
 *
 * Add the new "weight" field to the interface.
 */
function mymodule_graphql_compose_entity_base_fields_alter(array &$fields, string $entity_type_id): void {
  if ($entity_type_id === 'paragraph') {
    // You could use any entity type base_field annotation in the array.
    // @see https://drupal-graphql-compose.github.io/documentation/#/extending/entity_type
    $fields['weight'] = [];
  }
}

Does this answer the feature request?

#3 does the trick. Thanks for the help!
