Astro

Hvor er vi?

  • Hvad består en Astro-component af?
  • Hvordan sender vi props?
  • Hvor skal vi placere vores styles?
  • Hvor lægger vi billeder?
  • Hvordan fetcher vi, og hvordan looper vi over data?
    • Ved vi, hvad der skal kopieres og rettes i?

Dynamiske routes

I dag

Routing

Statiske routes / fil-baseret

Det, vi gør nu

Build time

SSG Mode

Fordi vi skal arbejde med et statisk site, skal Astro på forhånd ("build time") vide, hvilke routes der skal genereres.

getStaticPaths()

SSG Mode

Det gør vi ved at kalde en "magisk" function, der hedder getStaticPaths().

Den skal returnere et array af objekter med en params-egenskab. Hvert af disse objekter vil generere en tilsvarende route.
