Controller

PSX allows you to define complete type-safe controllers which map every value from the HTTP request to an argument. This idea is inspired by great frameworks like Spring or NestJS.

src/Controller/Population.php
class Population extends ControllerAbstract
{
    #[Get]
    #[Path('/population')]
    public function getAll(#[Query] ?int $startIndex = null, #[Query] ?int $count = null): Model\PopulationCollection
    {
        // @TODO return population entries
    }

    #[Post]
    #[Path('/population')]
    #[StatusCode(201)]
    public function create(#[Body] Model\Population $payload): Model\Message
    {
        // @TODO create population entry
    }
}

Dependency Injection

A key concept in PSX is dependency injection. Internally we use the Symfony DependencyInjection Component to automatically inject all dependencies into your controller so that you can build a clean architecture.

src/Controller/Population.php
class Population extends ControllerAbstract
{
    public function __construct(private MyService $myService)
    {
    }

    #[Post]
    #[Path('/population')]
    #[StatusCode(201)]
    public function create(#[Body] Model\Population $payload): Model\Message
    {
        $id = $this->myService->create($payload);

        $message = new Model\Message();
        $message->setSuccess(true);
        $message->setMessage('Population record successfully created');
        $message->setId($id);
        return $message;
    }
}

Client SDK

One of the innovative features of PSX is, that you can automatically generate a client SDK for your API. Through a simple command you can generate a complete type-safe client SDK to communicate with your API.

Console
php bin/psx generate:sdk spec-openapi
php bin/psx generate:sdk client-typescript
php bin/psx generate:sdk client-php

Symfony Bundle

In case you are a fan of Symfony you can simply use the PSX API Bundle to integrate all PSX features.
