Endpoints /.well-known/* are not included

Describe the bug

We are hosting some endpoints under the /.well-known/ path prefix, this prefix is quite standard and enforced by Android et iOS domain checks. During the “adapt” phase, endpoint files are not copied by the builder writeServer() funnction. Paths starting with a dot are explicitly filtered out.

Reproduction

I created a reproduction app there https://github.com/trecloux/svelte-kit-dot-path-filtered-out

Serve .well-known/file from static folder. I am using the same in production in a project

Unfortunately, I’m using dynamic content there

I think adapters should respect config.kit.routes and/or include .well-known as an exception.

I agree. I think the blanket filter is a bug, but besides @sidvishnoi 's workaround you can work around it this way as well:

Rename .well-known to [...wellKnown=wellKnown]

src/routes/.well-known => src/routes/[...wellKnown=wellKnown]/

and then: src/params/wellKnown.ts is

import type { ParamMatcher } from '@sveltejs/kit';

export const match: ParamMatcher = (param) => {
  const isWellKnownPath = /^\.well-known$/i.test(param);
  return isWellKnownPath;
};

That way the file doesn’t start with a . and isn’t filtered by the adapter.
