An da safidar a gida zuwa HTML na jiya lokacin gida kuma an ajiye a kan CDN. Mafi sauri a iya kariya, amma abin kunya ya kasance sanye har zuwa gida na gaba. Kyau wajen abubuwanda ba su canja kaɗan ba: shafukan kasuwa, bayani, abubuwan blog.
// HTML generated FRESH on every request
export default async function Page() {
const data = await fetch("...", { cache: "no-store" }).then(r => r.json());

Server yana sakawa safidar akan kowane buɗe, don haka bayanai kuma na al'ada — akan faɗi da naushe amsawa da loadin server akan kowane ziyarci. Kyau wajen bayanai na kada hankali ko kuma na kullun sabo: allunan shida, shafukan asusun, sakamakon bincike.
// Static, but automatically rebuilt in the background every N seconds

SSR slower always fresh every request dashboards, personalized
ISR fast every N seconds occasional catalogs, news
A cikin App Router kuna zaɓi waɗannan ta hanyar-buɗe ta hanyar zaɓuwan cache (force-cache = SSG, no-store = SSR, revalidate = ISR) maimakon ayyuka na musamman.
Sanin jujjuyawar — jiya shi ke sauri amma tsoho, SSR shi ke sabo amma tsada, ISR ya daidaita duka — yana ba ku iko na daidaita kowane safidar don daidaicin nisani da sabo na bayanai.
