Cannot npm run build, Error: Could not resolve "@node-rs/argon2-wasm32-wasi"

[joshdstockdale]

Describe the bug

Trying to build with adapter-cloudflare but I get the following error:

Using @sveltejs/adapter-cloudflare
✘ [ERROR] Could not resolve "@node-rs/argon2-wasm32-wasi"

node_modules/@node-rs/argon2/browser.js:1:14:
  1 │ export * from '@node-rs/argon2-wasm32-wasi'
    ╵               ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

You can mark the path "@node-rs/argon2-wasm32-wasi" as external to exclude it from the bundle, which will remove this error and leave the unresolved path in the bundle.

Versions:
"@sveltejs/adapter-auto": "^3.0.0",
"@sveltejs/adapter-cloudflare": "^4.7.4",
"@sveltejs/kit": "^2.0.0",
"@sveltejs/vite-plugin-svelte": "^4.0.0",

I've tried a number of vite.config.ts fixes to mark the package as external but no success:

export default defineConfig({
	plugins: [sveltekit()],
	build: {
		rollupOptions: {
			external: ['@node-rs/argon2-wasm32-wasi']
		}
	},
	ssr: {
		noExternal: ['oslo']
	}
});

Also, my svelte.config.js:

const config = {
	// Consult https://svelte.dev/docs/kit/integrations
	// for more information about preprocessors
	preprocess: vitePreprocess(),

	kit: {
		// adapter-auto only supports some environments, see https://svelte.dev/docs/kit/adapter-auto for a list.
		// If your environment is not supported, or you settled on a specific environment, switch out the adapter.
		// See https://svelte.dev/docs/kit/adapters for more information about adapters.
		adapter: adapter({
			routes: {
				include: ['/*'],
				exclude: ['<all>']
			},
			platformProxy: {
				environment: undefined,
				experimentalJsonConfig: false,
				persist: false
			}
		}),
		alias: {
			'@/*': './src/lib/*'
		}
	}
};

This a known issue, cloudflare itself doesn't support wasm modules, although don't know this can be fixed within sveltekit, would be very nice if so
For now noble hashes have a js implementation which works
