There is no middleware created by adapter-node

[bdadam]

Describe the bug

The readme in adapter-node linked from the svelte kit docs says:

The adapter exports a middleware (req, res, next) => {} that's compatible with Express / Connect / Polka. Additionally, it also exports a reference server implementation using this middleware with a plain Node HTTP server.
But you can use your favorite server framework to combine it with other middleware and server logic. You can import kitMiddleware, your ready-to-use SvelteKit bundle as middleware, from ./build/middlewares.js.

But I cannot find any middleware created by the adapter. I only have an index.js file in the build directory (besides the assets).

Is this an issue with the readme or with some configuration? Is there a way to get a middleware from adapter-node?

You're right, it seems like the latest version 1.0.0-next.43 doesn't even include these functionality yet, i looked into the source code. Maybe there was no new release since this feature was merged, the last adapter node release is 14 days old but the changes got merged 5 days ago.

#2051 should have had a changeset, but it didn't, so it was never released. cc @benmccann

Thank you all for the quick reaction and the fix. I can confirm that it works now as described in the readme. Thank you. :)
