Static manifest.json file is overridden with generated file

Describe the bug

A manifest file added to the static folder i.e. /static/manifest.json is overwritten with a generated SvelteKit file at runtime (happens with adapter-node & adapter-auto).

Reproduction

Add /static/manifest.json file:

{
  "name": "test"
}

Build / run app, request /manifest.json, response is like:

{
  ".svelte-kit/runtime/client/start.js": {
    "file": "_app/immutable/start-1e83f480.js",
    "src": ".svelte-kit/runtime/client/start.js",
    "isEntry": true,
    "imports": [
      "_index-e11c2291.js",
      "_index-b191a7c7.js",
      "_singletons-eca981c1.js"
    ],
    "dynamicImports": [
      "src/routes/__layout.svelte",
      ".svelte-kit/runtime/components/error.svelte",
      "src/routes/folder/[...path]/__layout.svelte",
      "src/routes/about/index.svelte",
      "src/routes/cart/index.svelte",
      "src/routes/folder/[...path]/index.svelte",
      "src/routes/index.svelte",
      "src/routes/photo/[id].svelte"
    ]
  },
  ...

Severity

serious, but I can work around it

Additional Information

manifest.json is specifically mentioned as an example of using a static file:

assets — a place to put static files that should have stable URLs and undergo no processing, such as favicon.ico or manifest.json

Is there any workaround for now?

You could simply name your manifest manifest.webmanifest.

That’s the official file extension for webmanifests anyway. https://developer.mozilla.org/de/docs/Web/Manifest

[benmccann]

manifest.json is a static file that Vite creates in the output directory and Vite copies the static assets to the output directory as well, so this seems like an issue that would need changes in Vite to address. Can you file an issue there? See https://github.com/sveltejs/kit#bug-reporting
