Conventions

The Spryker SDK defines the following conventions.

Task

In a task, id, short_description, version, type, and command are required properties. The task properties must meet the following conditions:

  • id must follow the schema <group>:<language>:<subgroup>, where <group> stands for validation or generation, <language> is PHP, and <subgroup> should be a descriptive name. For example, there can be a task with the following ID: validation:php:architecture.

  • version must follow the semver specification.

  • Every task must have a short_description.

  • type can have one of the following values: local_cli, local_cli_interactive, task_set, php.

  • command must be an executable command string or null

Task set

A task set must have the following properties:

  • type with the task_set value.

  • tasks with the list of the required sub-tasks.

  • Sub-task id in the tasks list.

  • Null value in the command property. For example, command: ~.

Workflow

There are no conventions for the workflow yet.

ValueResolver

A ValueResolver must meet the following conditions:

Note: The configurable ValueResolver interface should be preferred over the concrete implementation.

Setting

A setting must meet the following conditions:

  • Define the path with an underscore as a separator. For example, some_setting).

  • Define the scope setting_type: sdk/local/shared to distinguish if the setting is per project or global.

  • Define a type to be either array, integer, string, boolean or float.

  • Define the strategy to be used when setting the value. The allowed values are: merge, overwrite.

  • Define init as boolean. true means that this value is initially requested from the user.

Placeholder

A placeholder must meet the following conditions:

  • The placeholder's name must start and end with %. For example, %some_placeholder%.
  • Define optional: true/false to indicate if the placeholders needs to be resolved to run the task.
  • Use the id or a full qualified class name of an existing ValueResolver for the valueResolver field.

Console command

A console command must meet the following conditions:

  • Only basic input validation and output formatting SHOULD present in the console command.
  • protected static $defaultName SHOULD NOT be used because of performance reasons and future deprecation in Symfony 6.1 version. Instead protected const NAME SHOULD be provided and passed to the parent constructor as a parameter.

Naming conventions

There are the following conventions for naming entities:

  • Folder name: Must be in a singular form. For example, Event and not Events.

  • Class name: Must be in a singular form. For example, AcmeTask and not AcmeTasks.

  • Method name: Core convention must be followed.

  • Variable name:Core convention must be followed.

Contracts

A contract is an interface that allows users to customize the existing business logic. Contracts must meet the following conditions:

REST API

  • Controller SHOULD have no business logic.
  • Controller MUST have only one action method __invoke.
  • Controller MUST be placed in namespace SprykerSdk\Sdk\Presentation\RestApi\Controller\v1. The v1 is current version of SDK API.
  • Route MUST be placed in src/Presentation/RestApi/Resources/routing.yaml
  • Route SHOULD be named by template api_${version}_${controller_name}. Example: For action ValidatePhpCodestyleController::__invoke route is api_v1_validation_php_codestyle
  • Route's path SHOULD be named in hyphen-case. For task validation:php:codestyle path is /api/v1/validation-php-codestyle

TODO

  • .env usage.
  • Enums.
