Broken with next@9.5.3 and preact@10.4.8 #19

Hello,

first of all, I'm a huge fan of being able to use Preact together with Next.js. It's an awesome combination!

Unfortunately, I can not get it to work with next@9.5.3 (using TypeScript) and preact@10.4.8. Build successfully finishes, but when I start the app, nothing gets rendered.

To be correct, following gets rendered:

<html><head></head><body><undefined></undefined></body></html>

Are there any known issues?

Thanks!

UPDATE:

I got it to work using https://github.com/vercel/next.js/tree/canary/examples/using-preact

The only thing I now notice is that bundle size increase from 21.1 kB to 26.2 kB. I suspect this increase to caused by a different next.config.js than in your example.

Hmm - are you able to show your next.config.js? Typically <undefined> is caused by React.createElement being used with preact, which is not supported.

Just checked with the current master and it builds fine with TypeScript. The page is rendered via SSR correctly in production mode for me 👍
