Generate Data Transfer Objects directly from JSON objects

Json 2 DTO

Spatie's Data Transfer Object library is awesome, but typing out DTOs can quickly become a chore. Inspired by Json2Typescript style tools, we built one for PHP DTOs.

Web Version

Try it out at https://json2dto.atymic.dev
The web version has all of the same tools as the cli version in an easy to use GUI. When generating nested DTOs, the tool will create a zip file.

CLI Tool

Prefer to use the tool locally? You can install json2dto via composer and generate files directly from json files.

composer global require atymic/json2dto # Install Globally

composer require atymic/json2dto --dev # Install locally in a project

Usage

The tool accepts json input either as a filename (second argument) or via stdin.
You should run the tool in the root of your project (where your composer.json is located) as it will resolve namespaces based on your PSR4 autoloading config. If you aren't using PSR4, your generated folder structure might not match.

Examples

# Generate PHP 7.4 typed DTO
./vendor/bin/json2dto generate "App\DTO" test.json -name "Test" --typed

# Generate PHP 8.0 typed DTO (DTO V3)
./vendor/bin/json2dto generate "App\DTO" test.json -name "Test" --v3

# Generate a flexible DTO (with nested DTOs)
./vendor/bin/json2dto generate "App\DTO" test.json -name "Test" --nested --flexible

# Generate a DTO from stdin
wget http://example.com/cat.json | ./vendor/bin/json2dto generate "App\DTO" -name Cat
