Incompatible with Nextjs 5

[hidesminimally]

Hi there,
Thanks for creating this starter repo! I've cloned it and updated next to
"next": "^11.0.1" in package.json to run Next.js 5 and Webpack 5

and am running into the following error:

➜  eui-starter git:(master) ✗ yarn run dev

It seems that html-webpack-plugin is the dependency that's causing this problem

Anyone have ideas for how to get around this?

I've tried specifying a resolution in package.json but no change:

  "resolutions": {
    "html-webpack-plugin": "5.3.2"
  },

Mentioned this in their adoption thread: vercel/next.js#23498 (reply in thread)

Saw that @miukimiu posted on a similar issue that was resolved: #33 (comment)

Are there plans for Elastic UI Kit to support Webpack 5?

We don't have any active plans to upgrade this repo to the latest Next + Webpack, but it is something we want.

From reading the stack trace & next.js thread you linked to, it's may be possible this specific error can be resolved by updating some dependencies.

@chandlerprall Thanks for the quick response! For clarification, do you suggest forking the repo and updating some dependencies (such as html-webpack-plugin) for this to be solved on my end? Or are you suggesting that I may be able to solve this without forking?

[chandlerprall]

I'd try forking and updating those dependencies. If you get a functioning build with the latest next.js and webpack (or close to a functioning build), I'd be happy to review a pull request with any changes!

I opened a PR with a functioning webpack config :)
