SSR

Attribute binding with <SvelteHTML> is only applied on the client. To assign arbitrary attributes during SSR, use the apply function in the handle hook.

// hooks.server.js
import { apply } from '@jill64/svelte-html'

export const handle = async ({ event, resolve }) => {
  // ...
  return resolve(event, {
    transformPageChunk: apply({
      lang: 'en',
      prefix: 'example'
    })
  })
}
