sveltekit-page.url.pathname

Minimal repro of a $page.url.pathname bug when building a SvelteKit app using the static adapter.

UPDATE:

• This bug was partially fixed in @sveltejs/kit version 1.0.0-next.213
• The bug is no longer reproducible using version >=1.0.0-next.230

Repro steps

1) Run yarn dev

$page.url.pathname should display a forward slash (/).

1) Run yarn build

Build the app using the static adapter.

Serve the build folder:

serve build

$page.url.pathname displays //prerender/.

When inspecting build/index.html, hydrate.url is set to new URL("sveltekit://prerender/").

<!-- build/index.html -->
<script type="module">
  import { start } from "/_app/start-90034bf0.js";
  start({
    target: document.querySelector("#svelte"),
    paths: { base: "", assets: "" },
    session: {},
    route: true,
    spa: false,
    trailing_slash: "never",
    hydrate: {
      status: 200,
      error: null,
      nodes: [
        import("/_app/layout.svelte-96b29dd0.js"),
        import("/_app/pages/index.svelte-9bf7f989.js"),
      ],
      url: new URL("sveltekit://prerender/"),
      params: {},
    },
  });
