Description

Author

Sergii Pryz

This package can generate transfer objects using property hooks.

It can take a definition of a transfer object as an array or in a file in the YML format and generate a code file for the described transfer object class.

The package uses a template to define the transfer object class code using PHP class property hooks to implement the code of functions that are called to set or get the transfer object class variable values.

Innovation Award

January 2025
Number 4

A data transfer object is an object that is used in applications to pass information between different processes.

This package can quickly generate data transfer object classes from object class definitions passed as arrays or configuration files in YML format.

It uses PHP property hooks to simplify the definition of the generated data transfer object class.

new TransferGeneratorFacade()->generateTransfersOrFail($configPath);



echo <<<'STORY'

======================================================

        Try newly Generated Transfer Objects

foreach ($customerTransfer as $key => $value) {

    echo "key: $key, value: $value\n";

}



echo "CustomerTransfer properties count: {$customerTransfer->count()}\n}.";



$merchantTransfer = new MerchantTransfer();

$merchantTransfer->merchantReference = 'PL-234-567';

$merchantTransfer->country = CountryEnum::PL;

$merchantTransfer->isActive = true;



var_dump($merchantTransfer->toArray());



echo <<<'STORY'

======================================================

             Try how fromArray() works

======================================================



STORY;

$agentTransfer = new AgentTransfer()

    ->fromArray([

        AgentTransfer::CUSTOMER => [

            CustomerTransfer::FIRST_NAME => 'Max',

            CustomerTransfer::LAST_NAME => 'Mustermann',

        ],

        AgentTransfer::MERCHANTS => [

            [

                MerchantTransfer::COUNTRY => 'DE',

                MerchantTransfer::MERCHANT_REFERENCE => 'DE-234-567',

                MerchantTransfer::IS_ACTIVE => false,

            ], [

                MerchantTransfer::COUNTRY => 'PL',

                MerchantTransfer::MERCHANT_REFERENCE => 'PL-774-444',

Transfer Object Generator

Would you like to build lightweight Transfer Objects (TO) easily? You're in the right place!

Build TOs Using an Array as Blueprint

Imagine you have an array:

$data = [
    'firstName' => 'Jan',
    'lastName' => 'Kowalski'
];

TO facade method helps to convert array into YML definition file:

Customer:
  firstName:
    type: string
  lastName:
    type: string

Generator console command builds TO based on definition file:

$customerTransfer = new CustomerTransfer();
$customerTransfer->firstName = 'Jan';
$customerTransfer->lastName = 'Kowalski';

How it works in action can be found on Wiki: - Try Sample to generate Definition files - Try Sample to generate TOs - Try Advanced Sample to generate TOs

Key Features

Interface methods: implements `fromArray()`, `toArray()`
Standard interfaces: implements `IteratorAggregate`, `JsonSerializable`, and `Countable`
Lightweight: TO includes only data without any business logic
Nullable: supports both attribute types nullable and not nullable (`required:`)
BackedEnum: supports `BackedEnum`
Adaptable: compatible with custom Data Transfer Object (DTO) implementation

Installation

Composer installation:

$ composer require picamator/transfer-object

Usage

Terminal

Run command bellow to generate Transfer Objects:

$ ./vendor/bin/generate-transfer [-c|--configuration CONFIGURATION]

Please check Wiki for more details: - Command Configuration - Definition File

Facade Interface

Facade interface DefinitionGeneratorFacadeInterface is used to generate YML definition file based on array.

Please check Wiki for more details: - Facade Interfaces - Visualizing Diagrams
