README

Switon's application bootstrap kernel for env loading, config merging, provider lifecycle, and fatal handling.

Highlights

• Single bootstrap entrypoint: KernelInterface::start() starts the application from one contract.
• Config loading: root YAML and PHP config files are merged together.
• Provider discovery and overrides: built-in and app providers are loaded in one bootstrap flow.
• Autowiring and boot order: services are wired before runtime control is handed over.
• Fatal handling: the kernel sets up fatal handling during bootstrap.
• Runtime checks: the kernel includes a version command for quick verification.

Installation

composer require switon/kernel

Quick Start

use Switon\Kernel\Kernel;

class AppKernel extends Kernel
{
    public function start(): void
    {
        parent::start();
        // Attach HTTP server, CLI loop, worker, etc.
    }
}

(new AppKernel(__DIR__))->start();
