Malformed svelte.config.js

[mylastore]

updated today to latest sveltekit and adapter node see below and using example configuration listed on sveltekit documentation and I am using node adapter as you can see.

    import node from '@sveltejs/adapter-node'
	kit: {
		adapter: node(),

  "@sveltejs/adapter-node": "^1.0.0-next.0",
  "@sveltejs/kit": "^1.0.0-next.1",

now getting this error:

Malformed svelte.config.js
Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: /mnt/Backup/sys/now/svelte-kit/svelte.config.js
require() of ES modules is not supported.
require() of /mnt/Backup/sys/now/svelte-kit/svelte.config.js from /mnt/Backup/sys/now/svelte-kit/@root is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules.
Instead rename svelte.config.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from /mnt/Backup/sys/now/svelte-kit/package.json.

This sounds like maybe #1618. From those error messages, it's definitely not the latest version of Kit getting used somewhere.

updated to "@sveltejs/kit": "^1.0.0-next.113" and I am pass the original error on this issue, but a new one was generated see below. At least the app is running (who knows for how long :) )

This fixed this issue

import node from '@sveltejs/adapter-node'
	kit: {
		adapter: {
			adapt: async () => await node()
		},
}

[benmccann]

Ok. I'll go ahead and close this since it sounds like the issue is fixed now

@benmccann
Can you please update this on the docs?

import node from '@sveltejs/adapter-node'
kit: {
adapter: {
adapt: async () => await node()
},
}

Thanks

[benmccann]

The adapter isn't async: https://github.com/sveltejs/kit/blob/master/packages/adapter-node/index.js

That shouldn't be necessary. I just tested on my project and don't need to do it. Can you provide a repo where it is necessary?

I have a private repo I'm currently working on,
when I try to set svelte.config.js like so:

import node from '@sveltejs/adapter-node';
import preprocess from 'svelte-preprocess';
/** @type {import('@sveltejs/kit').Config} */
const config = {
    kit: {
        adapter: node(),
     },
    preprocess: [
        preprocess({
            postcss: true,
        }),
    ],
    kit: {
        // hydrate the <div id="svelte"> element in src/app.html
         target: '#svelte',
     },
 };
 
export default config;

I get this:

> TODO@0.0.1 build
> svelte-kit build

/sveltekit/node_modules/@sveltejs/adapter-node/index.js:8
builder.copy_server_files(out);
^

Press return ...

But if I use:

adapter: {
adapt: async () => await node(),
},

as @mylastore wrote in his last comment everything works.

[benmccann]

That's not enough info to reproduce. I have basically the same exact config and don't get the error you're talking about. I think you probably have an outdated dependency or something, but can't tell from the info here

[shlomocarmeter]

I'll try to update and see how it goes.
Thanks

[mylastore]

The issue is that you need to move almost all devDependencies to dependencies and that work for me specifically when you deployed
