Developer Experience
Hvordan det føles at bygge noget
Astro
Astro
Et framework, der bl.a. handler om DX
Framework
Et værktøj, der hjælper med at bygge hurtigere og smartere
(... men ikke flottere...)
Hvorfor lige Astro?
- Det er let at komme i gang med
- Forholdsvis lille læringskurve
- Det er bare HTML & CSS...
Marketing-afdelingen
Hvad hjælper Astro med?
- Struktur og overblik
- Genbrug af dele i stedet for copy-paste
- Styling uden konflikter
- Diverse optimeringer
Astro løser ikke ét stort problem, men fjerner mange små irritationer, du allerede har accepteret som “sådan er webudvikling”.
Komponenter
Genbrug af dele i stedet for copy-paste
Komponenter
Genbrug af dele i stedet for copy-paste
Hvornår copy-paster I kode?
Hvornår er noget en komponent?
- En genbrugelig skabelon, der kan modtage data
- Hvis noget html skal copy-pastes, så er det nok en component
- Hvis du kan give det et navn (a la footer) så er det nok en component
Alt kan være en komponent, men gode komponenter handler om overblik og klarhed; gør koden lettere at læse.
gruppe-øvelse
Identificer komponenter
Kan du og din sidemakker få øje på komponenter?
- Hvilke dele gentager sig, hvis der var 10 indlæg? (hvad ville du kopiere?)
- Hvilke dele kunne få deres eget navn?

Når vi arbejder i Astro…
• browseren forstår ikke "import", "<Header />" mm.,
• så koden kører ikke direkte i browseren.
• “Live server” virker ikke her.
• koden skal samles og oversættes først.
Derfor har vi installeret Node
Udviklingsmiljø, der kan:
• forstå Astro-filer
• samle komponenter til HTML
• starte en lokal server
• opdatere siden automatisk, når vi gemmer

Det er bare et program på computeren,
der kan køre JavaScript uden for browseren.
Astro bruger det til at bygge hjemmesiden,
før browseren ser den.
