Add a command to generate batch service

Please add a command to generate batch service.
Currently there is no command to generate batch class.
Hence we need to code same boilerplate code again and again.
Please Create a generator class to generate batch service.

Hi @bhanu951

Proposed Solution

Introduce a new generator command: generate:batch-service, which will create a batch service class with the required structure to use Drupal's Batch API.

namespace {{ namespace }};

use Drupal\Core\Batch\BatchBuilder;
use Drupal\Core\StringTranslation\StringTranslationTrait;

class {{ class }} {
  use StringTranslationTrait;

  public function buildBatch(array $items) {
    $batch_builder = new BatchBuilder();
    $batch_builder
      ->setTitle($this->t('Processing items...'))
      ->setFinishCallback([$this, '{{ finished_callback|default("finished") }}']);

    foreach ($items as $item) {
      $batch_builder->addOperation([$this, '{{ operation_callback|default("processItem") }}'], [$item]);
    }

    return $batch_builder->toArray();
  }

  public function {{ operation_callback|default("processItem") }}($item, array &$context) {
    // TODO: Implement batch processing logic.
  }

  public function {{ finished_callback|default("finished") }}(bool $success, array $results, array $operations) {
    if ($success) {
    // TODO: Implement batch processing logic.

    }
    else {
    // TODO: Implement batch processing logic.

    }
  }
}
