Astro

Hvor er vi?

Hvad er en component i Astro?
Hvad er props?
Hvad er et <slot />?
Hvad er scoped styles?
Hvordan starter man en dev-server (live server)?
- Hvordan stopper man dev-serveren?
Er Astro smart (eller har det i det mindste potentiale)?

Pages

speciel mappe

Pages

I /pages-mappen findes diverse (under)sider
Filer, der ender på .astro eller endda .html
Sider i /pages begynder altid med små bogstaver, selvom de har endelsen .astro (til forskel fra components)
Der kan linkes imellem siderne med et normalt a-tag:

<nav>
  <a href="/">Home</a> <!-- index.astro -->
  <a href="/search">Search</a> <!-- search.astro -->
</nav>

Layout-components

We conventionally use the term “layout” for Astro components that provide common UI elements shared across pages such as headers, navigation bars, and footers.

Projektarbejde

Installér Astro
Lav en layoutfil
Opret pages
Planlæg components
Skriv den grundlæggende, generelle CSS
Læg en plan, hvem tager hvad
Læg det på GitHub og tilføj “collaborators”
Klon GitHub repo til gruppens øvrige medlemmer og
kør npm install, når der er klonet (ellers virker det ikke!)

Én af jer opretter et projekt, og de andre kloner og kører npm install
