Switon Context Package

Switon's runtime state manager for ContextAware components, including HTTP request isolation and coroutine sharing.

Highlights

• Request isolation: mutable state stays out of long-lived services.
• Automatic context binding: getContext() resolves the matching context for each component.
• Coroutine sharing: child coroutines can inherit or reset context as needed.
• Lifecycle events: child-context creation and propagation are observable.
• Scoped runtime state: ContextManager keeps the active context available for the current request or coroutine.

Installation

composer require switon/context

Quick Start

use Switon\Core\Attribute\Autowired;
use Switon\Core\ContextAware;
use Switon\Core\ContextManagerInterface;

final class RequestStateContext
{
    public array $vars = [];
}

final class RequestState implements ContextAware
{
    #[Autowired] protected ContextManagerInterface $contextManager;

    public function getContext(): RequestStateContext
    {
        return $this->contextManager->getContext($this);
    }

    public function remember(string $key, mixed $value): void
    {
        $this->getContext()->vars[$key] = $value;
    }
}
