Using serve to deliver a static pre-built create-react-app.

serve -s /web/build --listen 5000 --no-clipboard

The file .well-known/apple-app-site-association is part of the served directory but user receives the contents of index.html instead of the static file.

A file just next to it .well-known/assetlinks.json is being resolved correctly.

    "relation"....

I've tried defining a serve.json config with excluded directory in cleanUrls but did not solve it.

{
    "cleanUrls": [
      "/**",
      "/!.well-known/**"
    ]
}

Universal Links documentation: https://developer.apple.com/library/archive/documentation/General/Conceptual/AppSearch/UniversalLinks.html

Any help would be appreciated!

Having the same issue, anyone have a fix for this?

shameless self-promotion alert:
this feature is fixed in my @warren-bank/serve fork of serve

The fix for this is to create the apple-app-site-association as apple-app-site-association.json and then create a rewrite rule inside of a file in your public directory called serve.json. The contents of that file should look like this.

{
  "rewrites": [
    {
      "source": "!.well-known/**",
      "destination": "index.html"
    },
    {
      "source": ".well-known/apple-app-site-association",
      "destination": ".well-known/apple-app-site-association.json"
    }
  ]
}

Then when you start your static file server, you don't use the -s or --single argument. You start it using the following command.

serve -c serve.json

The first item will send all requests that don't exist inside of .well-known to index.html, and the second rewrite will send requests for that specific URL to the apple-app-site-association.json file and assign a content-type: application/json header to it. All other files with file extensions should be served as normal, ignoring any rewrite rules.
