NextJS is not supported with Preact, FYI.

We don't provide an implementation for use yet through compat, which looks like the issue.

Hey! Sorry for the (very) late response.

This is not a valid reproduction. Please follow the instructions we laid out in the bug template, it's there so we can help you better.

Unfortunately, that's all that happens by the time that the error occurs. I build the application, run it, go to the website and I see a blank page with that error logged in the console.

That seems to be the issue, the use hook is new so should've expected that not all libraries support it yet 😅

Are there plans for official Next.js support?

"Build a NextJS app" is not a valid reproduction. As the issue template instructs, we need a repo we can clone or a Stackblitz/CodeSandbox to look at. Anything else has us blindly guessing at your setup, we have absolutely no idea how you configured it.

Without a reproduction there's very little chance anyone will be able and willing to help.

Are there plans for official Next.js support?

NextJS will not be supported, no.

They killed any chance of continued support (not that we necessarily loved maintaining the plugin either, it often broke) and entirely bought into React.
