Hi @krishnaTORQUE!

This might be related to #237. Could you possibly try the potential solution outlined in that issue and name the entry file to index.mjs in node_modules and see if the error goes away? Then that might be the change that is needed.

@EmilTholin
I tried & it worked but svelte/register does not have mjs support.

@krishnaTORQUE did you ever find a solution? I need SSR for SEO support and since this doesn't look like it's going to get fixed, I've started looking for alternatives to this library.

Hi @atsepkov

The solution which I have implemented is quite hard & only works on linux.
I am using rust in the backend & this is how I SSR. Rust get data from node & render.
Here you go

# src/pages/
- Home.svelte
- About.svelte

# src/App.svelte
<Router>
...
</Router

# src/ssr.cjs
require("svelte/register");

const args = process.argv.slice(2);

/**
 * Args *
 * @Param 0 Page/File Name Only
 * @Param 1 Props in JSON String Format
 */
const page = require(`./src/pages/${args[0]}.svelte`).default;

const render = page.render(args[1] ? JSON.parse(args[1]) : {});

console.log(JSON.stringify(render));

# usage
- node src/ssr.cjs Home ‘{}’
-  node src/ssr.cjs About ‘{"name": "Krishna"}’

If you are using vite then the solution will be slightly different. Vite has some cool features for SSR & Typescript.
