Custom logger?

[notrab]

I was thinking we could do something like this:

<?php

namespace Dumbo\Helpers;

use Dumbo\Context;
use Psr\Http\Message\ResponseInterface;

class Logger
{
    private static function colorizeStatus(int $status): string
    {
        return match (true) {
            $status >= 500 => "\033[31m$status\033[0m", // Red
            $status >= 400 => "\033[33m$status\033[0m", // Yellow
            $status >= 300 => "\033[36m$status\033[0m", // Cyan
            $status >= 200 => "\033[32m$status\033[0m", // Green
            default => "\033[37m$status\033[0m", // White
        };
    }

    private static function formatElapsedTime(float $elapsed): string
    {
        return $elapsed >= 1000
            ? sprintf("%.2fs", $elapsed / 1000)
            : sprintf("%.0fms", $elapsed);
    }

    public static function logger(callable $logFunc = null): callable
    {
        return function (
            Context $c,
            callable $next
        ) use ($logFunc): ResponseInterface {
            $start = microtime(true);
            $method = $c->req->method();
            $path = $c->req->path();

            $defaultLogFunc = function (string $message) {
                error_log($message);
            };

            $log = $logFunc ?? $defaultLogFunc;

            $log(sprintf("<-- %s %s", $method, $path));

            $response = $next($c);

            $status = $response->getStatusCode();
            $elapsed = (microtime(true) - $start) * 1000;
            $colorizedStatus = self::colorizeStatus($status);
            $formattedTime = self::formatElapsedTime($elapsed);

            $logPath = $c->req->routePath() ?: $path;
            $log(
                sprintf(
                    "--> %s %s %s %s",
                    $method,
                    $logPath,
                    $colorizedStatus,
                    $formattedTime
                )
            );

            return $response;
        };
    }
}

Which means it can be used like this:

<?php

require "vendor/autoload.php";

use Dumbo\Dumbo;
use Dumbo\Helpers\Logger;

$app = new Dumbo();

$app->use(Logger::logger());

I do think there's an issue with 404 routes and that those won't be matched so there might need to be some updates to findRoute to render run middleware too.

Could this also be used to log into log files for debugging or finding errors?
