External imports can't build

[livehtml]

Describe the bug

I want to put in the root dir of SvelteKit my config file: app.config.js (near svelte.config.js, package.json, etc)
So I create alias $base, mark file as external and use it anywhere in app via import (import appConfig from "$base/app.config"):

config = {
    kit: {
        adapter: adapterNode({
            esbuild(defaultOptions) {
                return {
                    ...defaultOptions,
                    external: [...Object.keys(JSON.parse(readFileSync('package.json', 'utf8')).dependencies || {}), "*app.config.js"]
                };
            }
        }),
        vite: () => ({
            build: {
                rollupOptions: {
                    external: [/app\.config\.js/],
                    // makeAbsoluteExternalsRelative: 'ifRelativeSource'
                },
            },
            resolve: {
                alias: {
                    '$base': path.resolve('./'),
                }
            },
        })
    }
};

Everything works in DEV but when I want build via adapter-node I've got an error:

Using @sveltejs/adapter-node
Cannot find module '/home/user/Projects/Svelte/site/sources/.svelte-kit/output/server/app.config.js' imported from /home/user/Projects/Svelte/site/sources/.svelte-kit/output/server/app.js

 ELIFECYCLE  Command failed with exit code 1.

I spent much time to find solution and only possible is made path absolute during rollup build. For it helps option makeAbsoluteExternalsRelative: 'ifRelativeSource' (by default it's true in rollup and looks like error with it — rollup writes incorrect relative path)
So, with this option my config file imports from absolute path and works as expected. But I need solution to move my app in another place without hard coded imports.

Reproduction

Use code sample above

[benmccann]

there's no longer a second bundling step with esbuild in adapter-node, so please note the removal of the esbuild option: https://github.com/sveltejs/kit/tree/master/packages/adapter-node

@benmccann oh, missed it, thanks. But behaviour (error) the same.

[Rich-Harris]

You should be able to do path.resolve('app.config.js') and have it correctly externalised (while still using a relative import). Will need a repro to investigate further though, I'm afraid.

Closing due to inactivity and lack of reproduction.

Still not work, add

  build: {
    emptyOutDir: false,
    rollupOptions: {
      external: ["/plugins/siyuan-plugin-publisher-pro/app/libs/publisher-service/publisher_service.js"],
    },
  },

but still report Error [ERR_MODULE_NOT_FOUND]: Cannot find module '/plugins/siyuan-plugin-publisher-pro/app/libs/publisher-service/publisher_service.js' imported from /Users/terwer/Documents/mydocs/siyuan-plugins/siyuan-plugin-publisher-pro-src/apps/publisher-app/.svelte-kit/output/server/entries/pages/_layout.ts.js

Fixed, I disable ssr import by the following code

const initWasm = async () => {
  if (!isBrowser) {
    return
  }

}
