Update Preact Example

[kurtextrem]

Preact supports hot loading: https://github.com/developit/zero-to-preact/commits/master

(It seems to work anyway. I just removed React from the using-preact example and HMR still does its thing)

[kurtextrem]

Also using-preact is missing a .babelrc file (which is mentioned in the readme).

The .babelrc isn't needed anymore. React is dropped via module-alias + the next.config.js changes.

Hello,

@kurtextrem I just tried using preact + next.js, but removing all the conditional if (dev) give me this error :

This module was not found:
* react-dom/lib/ReactReconciler in ./~/next/dist/client/next-dev.js

Here is a gist of all my files : https://gist.github.com/jgoux/e188f17f0b121684b3a6bbc0189e0cb5

What did I miss ?

[lukeed]

@jgoux You're missing react-dom. Next.js still requires a React environment in order to build & develop. As pointed out in #1564, the final output actually still includes React in the client bundle.

Oh I miss this one, thanks for the quick reply @lukeed ! 👍
