Selam ben laravelde sitemap için spatie sitemap paketini kullanayım dedim chat gptye sordum uzun süreli kod iyileştirmesi sonrası şöyle kodlar aldım sizce hatalı bir tarafı var mıdır ?
Ayrıca sorum şudur ki ben rotue ve app/Console/Commands/UpdateSitemap.php da aynı şeyleri yazmalı mıyım ?
Sunucuya atıcam o yüzden sorayım dedim cron falanda ekleyeceğim.
