FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:

If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.

Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
To use Composer is sometimes complicated. Especially for beginners.
Composer needs much resources. Sometimes they are not available on a simple webspace.
If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Please rate this library. Is it a good library?

Informations about the package dto

jooservices/dto

A PHP 8.5+ attribute-driven DTO and Data library: immutable Dto and mutable Data objects, constructor-first hydration, opt-in validation, serialization control, collections, and JSON Schema / OpenAPI generation. One runtime dependency: psr/http-message (interface-only).

[!WARNING] v3.0.0 is a complete ground-up rebuild of this package and is NOT backward compatible with any previous version (v1.x, v2.x). Rewrite DTO classes for the v3 API before upgrading; there are no legacy shims or deprecation bridges. See the changelog.

Upgrade highlights

v3 has a new DTO/Data engine, constructor-first hydration, and explicit key-space rules.
jooservices/exceptions is no longer a runtime dependency; psr/http-message supports fromRequest().
with(), merge(), and clone() use property names and rebuild through the constructor.

Features

Immutable Dto and mutable Data objects with typed, constructor-first hydration.
Factories for arrays, JSON, objects, and PSR-7 requests; collection and partial-payload support.
Attribute-driven mapping, casting, transforms, validation, and serialization control.
Immutable copies, merging, comparison, hashing, and lazy derived properties.
JSON Schema and OpenAPI generation, structured exceptions, and cached reflection metadata.

Requirements

PHP >= 8.5
Extensions: dom, libxml
psr/http-message (fromRequest()), optional: psr/log (Engine debug logging)
Docker (recommended — all local tooling runs in php:8.5-cli-bookworm)

Installation

Quick start

Design notes

Every DTO declares a constructor with public promoted properties; constructor-less classes are unsupported.
Each entry point owns exactly one key space:

Entry point	Key space
`new UserDto(...)`	Property names — already-typed values
`UserDto::from()` / `fromArray()` / `fromJson()` / `fromObject()` / `fromRequest()`	Source keys — resolved via `MapFrom` / naming strategy
`$dto->with(...)` / `merge(...)`	Property names only — immutable copies built through the constructor

Validation is opt-in via Context; casting and pipelines never silently change scope when a Context argument is omitted.

Development

All PHP tooling runs inside Docker (php:8.5-cli-bookworm via Docker Compose).

Command	Purpose
`make validate`	`composer validate --strict`
`make lint`	Pint, PHPCS, PHPStan, PHPMD, PHP-CS-Fixer
`make test`	PHPUnit (Unit + Integration)
`make test-coverage`	PHPUnit with Clover coverage
`make audit`	Composer audit
`make bench`	phpbench
`make ci`	lint + coverage run (local CI parity)

Every linter runs at maximum strictness with no ignore lists — fix issues at the source instead of suppressing them.

IDE setup: Cursor / VS Code — install recommended workspace extensions; format-on-save runs Pint via tools/pint (Docker). PHPStorm — inspection profile + Pint file watcher.
