Can you start Sveltekit programmatically from another directory?

[alexbjorlig]

I'm trying to simplify some test setup in my project, and came up with the idea to run Sveltekit like this. However it only works when the script is next to sveltekit. Is it possible to call createServer from another directory?

**test script in the same directory as svelte.config - that works!)

import { createServer } from 'vite';

async function main() {
    const server = await createServer({
        server: {
            port: 1337,
        },
    });
    await server.listen();
    console.log(server.printUrls());
}
main();

This does work, but only if running in the same directory as the sveltekit project. If I move this to the parent directory, I get:

Could not auto-determine entry point from rollupOptions or html files

(setup that does not work, in parent directory):

import { createServer } from 'vite';

async function main() {
    const server = await createServer({
        root: './web-app', // <== I tried setting the root to various values, but did not seem to work.
        server: {
            port: 1337,
        },
    });
    await server.listen();
    console.log(server.printUrls());
}
main();
