JTC Solutions Code Generator Bundle

Symfony bundle that helps generate boilerplate code for CRUD Controllers (List, Detail, Create, Update, Delete), DTOs, Repositories and Services.

Designed primarily for Domain-Driven Design structured applications.

Installation

1. Require the bundle using Composer:

composer require jtc-solutions/code-generator --dev

(Note: Typically used as a dev dependency)

2. Enable the bundle:
   If your application doesn't use Symfony Flex, you'll need to manually enable the bundle by adding it to your config/bundles.php file:

// config/bundles.php
return [
    // ... other bundles
    JtcSolutions\CodeGenerator\JtcSolutionsCodeGeneratorBundle::class => ['dev' => true],
];

Configuration

Create a configuration file (e.g., config/packages/dev/jtc_solutions_code_generator.yaml) to define how the generator should behave.

# config/packages/dev/jtc_solutions_code_generator.yaml
jtc_solutions_code_generator:
    global:
        # Supported variables are {domain} and {entity}
        # Example: App\Domain\Catalog\Entity\Product -> domain=Catalog, entity=Product
        namespace:
            # Template for generated controller namespaces.
            controllerNamespaceTemplate: 'App\{domain}\App\Api\{entity}'
            # Template for generated DTO namespaces.
            dtoNamespaceTemplate: 'App\{domain}\Domain\Dto\{entity}'   
            # Template for generated Service namespace.
            serviceNamespaceTemplate: 'App\{domain}\Domain\Service\{entity}'
            # Template for generated Repository namespace.
            repositoryNamespaceTemplate: 'App\{domain}\Infrastructure\Repository'
            
        project:
            # Project source directory relative to kernel.project_dir
            # Example: 'src' or '.' if source is in the root
            projectDir: '%kernel.project_dir%/src' # Required

            # Base namespace corresponding to the projectDir
            # Example: 'App' for 'src/...'
            projectBaseNamespace: 'project' # Required

            # Fully qualified class name (FQCN) of the interface that all your entities implement.
            # Used by the DTO generator to identify entity properties.
            entityInterface: JtcSolutions\Core\Entity\IEntity # Required

            # Fully qualified class name (FQCN) of the class to use as a type hint
            # in DTOs when an entity property is detected.
            # Example: A property 'product' of type Product (implements IEntity)
            # will become 'product' of type EntityId in the DTO.
            dtoEntityReplacement: JtcSolutions\Core\Dto\EntityId

            # Fully qualified class name (FQCN) of an interface that generated
            # Request DTOs (for Create/Update) should implement.
            requestDtoInterface: JtcSolutions\Core\Dto\IEntityRequestBody
            
            # Properties that will be skipped and ignored for generations
            # useful for common properties that you do not want in your DTOs and service such as entity Id, or timestamps.
            ignoredProperties:
              - "id"
              - "createdAt"
              - "createdBy"

        openApi:
            # Fully qualified class name (FQCN) of the DTO used for error responses
            # in generated OpenAPI documentation.
            errorResponseClass: JtcSolutions\Core\Dto\ErrorRequestJsonResponse

            # Fully qualified class name (FQCN) of the DTO used for pagination metadata
            # in generated OpenAPI documentation for list endpoints.
            paginationClass: JtcSolutions\Core\Dto\Pagination
    
    # Configuration for controllers.
    # - "parent" is default extended class
    controllers:
        create:
          parent: JtcSolutions\Core\Controller\BaseEntityCRUDController
        update:
          parent: JtcSolutions\Core\Controller\BaseEntityCRUDController
        delete:
          parent: JtcSolutions\Core\Controller\BaseEntityCRUDController
        detail:
          parent: JtcSolutions\Core\Controller\BaseController
        list:
          parent: JtcSolutions\Core\Controller\BaseController

Placeholders

• {domain}: Extracted from the entity's namespace (e.g., Catalog from App\Catalog\Domain\Entity\Product).
• {entity}: The short class name of the entity (e.g., Product from App\Domain\Catalog\Entity\Product).

Usage

The primary way to use the bundle is via the provided Symfony console command.

php bin/console jtc-solutions:generate-crud <TargetEntityFQCN>

Note: The TargetEntityFQCN must be in quotes. Otherwise it is escaped.

Example:

php bin/console jtc-solutions:generate-crud 'App\Domain\Catalog\Entity\Product'
