Fix type error in generated Paraglide hook

[sfirrin]

Motivation

When creating a new project with Paraglide and TS, the generated src/hooks.ts file has a type error:

I was able to fix it in my own project by following the Paraglide docs to add the reroute: Reroute type

Change

This change checks for TS and conditionally imports and adds the type

Testing

Creating a new project using the locally built dist/bin.js with TS and Paraglide generates a hooks.ts file equivalent to the Paraglide doc with no type error:

import type { Reroute } from '@sveltejs/kit';
import { deLocalizeUrl } from '$lib/paraglide/runtime';

export const reroute: Reroute = (request) => deLocalizeUrl(request.url).pathname;

Creating a new project with Paraglide in JS keeps the existing behavior:

import { deLocalizeUrl } from '$lib/paraglide/runtime';

export const reroute = (request) => deLocalizeUrl(request.url).pathname;

Running the Paraglide test passes:

➜  cli-sfirrin-fork git:(fix/add-type-to-paraglide-reroute) pnpm vitest run packages/addons/_tests/paraglide/test.ts

Thanks for your pr and detailed explanations. Could you please elaborate on how to replicate the problem initially? For me running npx sv create and npx sv add paraglide produces this file:

Which is different from what you are reporting. And the error for $lib/paraglide/runtime goes away instantly as soon as you run pnpm dev.

Could you also confirm that you are using up to date svelte, typescript packages and a current svelte vs code extension?
