Google Lighthouse — saytni 5 ta yo'nalishda baholaydi: Performance, Accessibility, Best Practices, SEO, PWA. Bepul, Chrome'da o'rnatilgan. Sayt sifatini bir necha daqiqada bilish.
Qanday ishga tushirish
1) Chrome → DevTools (F12). 2) Lighthouse paneli. 3) Mobile/Desktop tanlang. 4) Generate report. 5) 30-60 soniya kuting.
Performance (eng muhim)
0-100 ball. 90+ yashil, 50-89 sariq, <50 qizil. Asosiy ko'rsatkichlar: FCP, LCP, TBT, CLS, Speed Index. Har biri uchun aniq tavsiyalar beradi.
Accessibility
Ko'rmaydigan/eshitmaydigan foydalanuvchilar uchun moslik. Alt text, aria-label, kontrast nisbati, klaviatura navigatsiyasi. Yashil bo'lsa — yaxshi UX va SEO.
Best Practices
HTTPS, console xato, deprecated API, JS errors. "Avoid an excessive DOM size" — DOM 1500+ elementdan ko'p bo'lmasin.
SEO
Meta description, title, viewport, robots, alt, link descriptive text. Texnik SEO uchun yaxshi tekshiruv. Lekin kontent va backlinks tekshirmaydi.
PWA (Progressive Web App)
Manifest.json, service worker, offline rejim, install prompt. PWA qilmasangiz, bu bo'limni e'tibordan o'tkazsangiz mumkin.
CLI rejimi
npm i -g lighthouse → lighthouse https://sayt.uz --output html. Avtomatik CI/CD pipeline'da ishlatish mumkin. Har deploy'da reportni tekshirish.
Sayt.uz natijalar
