Øvelse

  1. Sæt jer sammen med sidekammeraten
  2. Brug 10 min. på at vise hinanden, hvordan I har løst opgaven
  3. Én af jer (eller begge to) skal navigere til GitHub-repo (Fronter)
  4. Klon det ned lokalt
  5. Kør npm install og npm run dev i terminalen
  6. Sammenlign og diskutér evt., hvad I ser i /src

Hvordan løste I den?

20-25 min.

Vi samler op sammen bagefter...

Hvordan løste vi den?

I dag

  • Pages & layouts

  • Conditionals

  • Deployment

Mål

  • Omorganisering af kode

  • Bruge betinget HTML / styling

  • Læg sitet på Netlify

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.

Kode, der ikke virker?

Astro

npm run build

Laver koden om til almindelig HTML, CSS og JavaScript

Netlify gør det hele for os

  1. Hvis du ikke allerede har en konto på Netlify (netlify.app), så opret en konto vha. din GitHub-konto
  2. Giv de nødvendige tilladelser til GitHub
  3. Under Sites i hovedmenuen på Netlify, vælger du Add new site > Import an existing project
  4. Via GitHub peger du på dit repository
  5. Klik derefter på Deploy site
  6. Find linket og verificér, at det virker

Push dit site til Netlify
