Access domain name dynamically in SvelteKit Sitemap

Svelte Sitemap

We have to specify the domain in sitemap, the usual practice is to store the domain in some object/variable and export it. In SvelteKit we can do the same.

In the development mode the domain can be localhost and for production it would be a real world domain.

Can I access the domain dynamically ?

Yes. Using url parameter in the get function as follows.

export async function GET({url}) {
  ......
  ......
  }

In the XML string we can access the domain using the hostname.

 import { get } from "svelte/store";

// @ts-ignore
export async function GET({url}) {
        
  return new Response( 
    `<?xml version="1.0" encoding="UTF-8" ?>
    <urlset

    {
      headers: {
        'Content-Type': 'application/xml'
      }
    }
  );
}
