Please mention any other relevant information
I am running node 17 and this bug seems similar to this bug in create-react-app

Please paste the results of npx preact-cli info here.

Just a note for anyone else having this issue, a temporary workaround is to use the current LTS version of Node

[rschristian]

Unfortunately it's a breaking change in Node that caused pretty widespread breakages across the ecosystem. See webpack/webpack#14532

You'll need to set the NODE_OPTIONS env var to use the OpenSSL legacy provider, i.e.:

package.json

{
  "scripts": {
    "dev": "NODE_OPTIONS=--openssl-legacy-provider preact watch"
  }
}

It doesn't look like Webpack v4 will ever get fixed, so this is required if you want to use v17+.

Is there any plans to upgrade preact-cli to use Webpack 5?

[rschristian]

Plans? Unfortunately no.

We'd like to upgrade, but we have limited maintainers with even more limited time; upgrading Webpack is always a very time consuming process. See #1579

Edit: Well this comment is what pushed me into starting it on a Friday night, so... we're trying to get there. No idea if/when I'll get that done though.

Closing this out as it's a duplicate of #1579 essentially.

Please track that for any further updates.
