Switon Log Package

Switon's PSR-3 logger for application services that want automatic categories, structured context, per-category filtering, and low-setup defaults.

Highlights

• Standard logger contract: LoggerInterface is the main logging contract.
• Automatic category routing: log categories can be derived from the caller.
• Structured context: placeholder interpolation and extra context stay structured.
• Output backends: stdout, file, syslog, and memory sinks are available.
• Category-aware filtering: Logger derives categories from the caller and applies per-category levels.

Installation

composer require switon/log

Quick Start

use Psr\Log\LoggerInterface;
use Switon\Core\Attribute\Autowired;

class UserService
{
    #[Autowired] protected LoggerInterface $logger;

    public function login(int $userId): void
    {
        $this->logger->info('User logged in', ['user_id' => $userId]);
    }
}
